        Guys,
      
        Who has or has not installed an ELT? It appears that it is required by the regs
      but I don't hear much on the list.

Hello one and all. My name is Chet and I have just purchased a Piet fusealodge from a fellow in Texas. I've been watching your list for about a week now and it looks like a great place for information to me. Mr. Nelson I live in Jefferson City and travel your way with my work for the state. And would like to take a look at your Piet some time. Also our EAA chapter 429 is holding a flying / carshow with a BBQ on Oct 9th from 9am to 2pm.

Chet, do you know Gabe Borbeau, a part time but mostly retired state pilot? I flew with him in his Cub a few weeks ago at the California Airport. I am still buzzing about that. Just give me a call. My home office is 417 882 8122, and my cell is 417 849 2997. If your EAA chapter is in Jeff, WEs SCott, my buddy, belongs to that and he is mostly an old car guy, semi retired from Dept of Health, and HE has a Piet project, too, plus 13 model A ford engines. Call me sometime. Hitting the rack, now, however, for an early start manana. --- Chet's Mail wrote: > > > Hello one and all.

Subject: Air Camper's response to Nigerian Spam
I get tons of spam from "wealthy" Nigerians in desperate need of hiding money in American bank accounts. So, I flood the Nigerian e-mail address with this response, from one of my accounts that will not accept any mail. If you are flooded with Nigerian spam too, maybe we can lock up all the ISPs in Africa by sending bogus mail back to these bozos. Below is the response I am sending. Dear Mr. (Name of Nigerian scam artist here__________), I am Piet Wannabe, a U.S. citizen by nationality. Presently, I reside in the Southern United States. My uncle Piet Wasabuilder, was the president of a large U.S. Airline. When the airline industry began to decline several years ago, politcal leaders in this nation contributed $200 million in cash, to keep my uncle's airline in business. Uncle Wasabuilder stashed the money in a secret location in the desert southwest in order to keep the funds protected. Unfortunately, my Uncle succumbed to a propellor accident when a mute aviator started an airplane engine on a dark and foggy night. The mute aviator was not able to shout "clear prop" when starting the engine and Uncle Wasabuilder walked into the propellor as the engine was cranking. And since it was dark and foggy, my uncle was not able to see and read the sign language when the mute aviator indicated with his hands, as he was waving sign language in the windscreen "clear prop." I am very confident that my deceased uncle buried his $200 million somewhere between El Paso, Texas and Las Vegas, Nevada -- in a dust-proof and water-tight lock box. Uncle Wasabuilder frequently took me on many flying adventures in an airplane he built, when I was a young boy. We frequently flew across the desert from El Paso to Las Vegas and uncle often remarked, "If I had a million dollars I wanted to hide, I'd bury it out here under 5 feet of sand." Although I was too small at the time to effectively see out of the window where uncle was referencing on the earth below, I think I have a good idea where his secret hiding place might be and I am extraordinarily confident that uncle buried the $200 million the government gave him recently. I seek your help in finding this money and I intend to make you a beneficiary of $150 million when I locate the funds. I only wish to keep a small amount of the money for sentimental reasons. And I'd like to have some cash reserves that would allow me to purchase all the parts and materials to complete a Pietenpol experimental aircraft, having a turbine engine, storm scope, IFR-GPS and some other modest instruments and equipment. I'll build this airplane only so I can retrace the flying adventures Uncle Wasabuilder took me on, between El Paso and Las Vegas many years ago. Oh, how I miss my dear uncle. You can help me in my quest by providing a new Hummer that would allow me to explore the desert between El Paso and Las Vegas. Since there are no hotels in the area I plan to travel, I ask that you also provide a highly modified Airstream travel trailer to be towed by the Hummer. The Airstream trailer needs to be fitted with a flat and reinforced roof, having a surface area 36 feet long by 8 feet wide. This will be suitable for landing a small Bell Jet Ranger that I ask you to provide. The helicopter is needed in order to search the desert as I drive the Hummer between El Paso and Las Vegas. As you know, the Hummer can go almost anywhere, but the Jet Ranger will be a great asset when searching vast areas around canyons and mountains. As soon as I receive your indication to assist me, I will inform you with the necessary modalities of how to proceed. Until then, in order to verify that you are in a position to provide the above mentioned tools for the search of the vast and open desert, please submit your bank account numbers as well as the account numbers to any and all credit cards you have. I am embarrassed to even ask that you submit this information, but let me assure you, this is simply a formality. The exchange of this information will help us develop trust in each other and establish credibility in regard to your ability to help in this rewarding endeavor. Also please provide the name of your first born child and your mother's maiden name. Kindest Regards and may God Bless You. Mr. Piet Wannabe, Esq. ________________________________________________________________________________

Be very careful with starting fluid...The ether in starting fluid is a solvent that removes the very thin oil film from the cylinders which evaporates quickly with the ether. Since the job of the oil rings is to limit the amount of oil which reaches the cylinders and combustion chambers it can take quite a few revolutions before the oil film is reestablished..the compression rings will run without lubrication during this period of time...I've also seen engines with the ringlands blown off the pistons from useing heavy shots of either in hot weather...I worked as a mechanic in a tractor shop for six years and several times heard guys say their tractor engine got hooked on starting fluid. Fact was it just didn't have enough compression to start without it because it ruined the rings...Go very easy with it. Of course you probably know this already but just in case.......Don't want anyone hurting their Piet engines..Ed >From: Waytogopiet(at)aol.com >Reply-To: pietenpol-list(at)matronics.com >To: pietenpol-list(at)matronics.com >Subject: Re: Pietenpol-List: Starting the Model A >Date: Fri, 24 Sep 2004 17:00:25 EDT > >Larry, After the usual break-in problems were solved, we found that a >half >turn on the gas adjustment valve, about four turns on the prop (with the >switch off), one shot of starting fluid in the carb heat inlet.....contact >and it >usually starts her on the first pull.

Subject: Starting the Model A
I don't know if this will help or not since I have never had much to do with Model A engines before, but I have had a lot of experience with Kinner radials which too are low compression engines. In fact, I think that the Kinner and Model A have a lot in common. The Kinners were hard to start sometimes. What worked (as well as did the ether) was to pour about a table spoon full of gasoline into the top cylinder (or better top three cylinders) then pull the prop through three or four times before turning on the mags. I was using plain old 87 octane auto fuel with Marvel Mystery Oil mixed in. Does anyone with Model A Piets use Mystery Oil in their gas? It sure extends the TBO of old radials. The low compression of the engines (especially on colder days) doesn't pull the fuel up into the cylinders very well. When the rings heat up and expand, they do a better job of pulling the fuel up. I have been known to apply a butane torch to the cylinders on cold days to heat up the rings to make them start better.

no particular reason really..... I saw a couple Piets on William Wynne's website that used that size, and the guy who made my prop also thought it would be a good size. I had my prop made by Tennessee Propellers. Since then I've fond that most Corvair powered Piets seem to go with a slightly smaller diameter and more pitch. I have plenty of static thrust, but I'm a little bit concerned if it'll produce good thrust once the plane is moving. I'm pretty sure it'll be ok and I'll certainly have awesome climb performance which is always good in my book. My dad is giong to use a Tennessee Propellers 64X32 or 62X34 on his 'Var powered Celebrity. He'll be buying his prop before I fly my Aircamper so I'll be able to try both sizes.

Subject: Al Schubert, Al Kelch...
I was pleased to see Alvin Schubert's name mentioned in reference to propeller carving and his book "How I Carve Propellers." Some of you my know that Alvin passed a few years ago. Following is a piece that I wrote shortly after Alvins passing for the Galesville Republican newspaper. At the time I was considering building a Volksplane, but once again, I came back to the Pietenpol instead. In fact, at Alvin's estate sale, I purchased the Pietenpol plans that Alvin had purchased back in 1968. Anyway, here's my tribute to Alvin... I should also mention that Al Kelch, who kept his magnificent collection of antique airplanes at Brodhead, passed away this last week on Sept. 21. See EAA's latest "Hotline." Last Flight: Alvin Schubert Remembered By Frederick Beseler, La Crosse, WI We lost a good friend when Alvin Schubert, rural Trempealeau, (Wis.) passed away on March 9th, 2002, at 85 years of age. Alvin grew up during aviation's Golden Age when pioneers like Lindbergh, Byrd, Hughes, Post, Doolittle, Earhart, Cochrane and Wittman blazed new trails across the sky=E2=80=94faster, farther and higher. "Pushing the envelope," as the test pilots say. They inspired a whole generation of kids like Alvin to get into aviation. Alvin was born in Genoa, Wisconsin, in 1916. His family later settled on the farm near Trempealeau where Alvin lived his entire life. I first encountered Alvin when I was a kid, growing up in Trempealeau. I was always building gas-powered model planes=E2=80=94control-line planes that go around in circles on the end of 40-foot long strings. My buddy, Claus Ryder, and I flew the planes in the small field below my parent's house on West Second Street. Around 1970 or so I decided to try free-flight modeling and so I built a balsa wood model of a Piper Cub that was powered by a little gas engine. Unlike control line models, free flight model planes require a large, treeless field from which to fly. One hot summer I pedaled my bicycle out of Trempealeau towards Centerville until finally I found a nice big, wide-open field just perfect for flying a free flight model plane. With a free flight model you set the rudder for a right turn, gas it up, start the engine and let her go. If successful, the airplane spirals upwards, circling left due to the propeller torque. Once the engine runs out of fuel=20and quits, it should glide slowly down, turning right in response to the bend in the rudder. Technicalities aside, you mostly pray that the model and all your hard work and the then expensive-for-a-kid $5.98 gas engine, doesn't simply=20fly straight away to the next county, never to be found. There was no danger of=20my Cub flying over the rainbow on that day. She took off and climbed away okay, but once the engine quit the model went into a nasty, ever-tightening spiral and bored straight down into the soft farm field. Test pilots call it "auguring in." While cleaning the dirt from the engine I noticed a farmer coming across the field, heading straight for me. No doubt it was the owner of the land that I was using for a flying field. I began packing up my tools, ignition battery=20and fuel as I was certain that he would chase me out of his fields. "Nice day for flying, isn't it?" he asked. "I believe that you need to bend the right aileron down just a little bit, and maybe bend the elevator up just a little_then she should fly pretty well!" I was amazed and astonished. First, he hadn't told me to get the heck off his land. Second, he spoke "airplane." But then I thought, "Who is this old farmer in the baggy coveralls, and how on earth would he know anything about flying and aerodynamics?" Appearances are deceiving. I soon learned that Alvin Schubert knew more about airplanes and aerodynamics than anyone else I ever knew. He was Valedictorian of the Class of 1938 at Galesville High School and he was forever and always tinkering with mechanical gadgets and engines. For example, Alvin had built=20a couple of tractors and then a working electrical generator for the family farm long before the power company came along. (Over the years I often wondered what this latter day Wright Brother would have accomplished had he gone on to college.) We got the model Cub fixed up and flying. He thoroughly enjoyed watching that little model fly. Standing there with his hands in the pockets of his bib coveralls, looking skyward as the tiny yellow plane floated upwards, Alvin said, "Well, you know, a model airplane obeys the same laws of flight that a full size airplane does." Alvin admitted that he had "monkeyed around with airplanes a little, now and then." He had done more than "monkey around." Alvin knew about flying and aerodynamics and how to build an airplane just as surely as William Boeing and Donald Douglas knew how to build airplanes. We walked over to one of his farm sheds. Alvin rolled the old weathered barn door open. Lo and behold, nestled among the straw bales was a real airplane! It was a trim little single-seat, all-silver plane that Alvin had designed and then built with his own two hands. It had a 21-foot wingspan and was powered by an early 36-horsepower Volkswagen engine, which was about the only thing on it that Alvin hadn't built from scratch. Even the propeller was designed and carved by Alvin. "I call her Der Fledermaus. Just step up right there, swing your leg into the cockpit and then you can sit in her," said Alvin. I asked if it actually flew. Alvin replied, "Well...yep...she flies pretty well...cruises along pretty fast on 36 horsepower. Well...I'm going to carve a new propeller with a little finer pitch to give her a little more zip on takeoff. Let's start her up." Before I could jump out, Alvin gave the propeller a couple flips and away she went, the little four-cylinder VW engine barking away through the stubby exhaust stacks. The wind from the propeller blew our hair. Alvin`s eyes sparkled. I was sitting at the controls of a real, running airplane! No disrespect to Der Fledermaus, but I recall looking through the Plexiglas windscreen and for a moment imagining that I was sitting in a World War II Spitfire or P-47 Thunderbolt. And then I remember thinking that I'd have to keep the whole experience a secret as I knew that my parents wouldn't care for the idea of their kid at the controls of a real, running airplane=E2=80=94much less a homemade airplane! That little plane truly was, and is, an engineering marvel. With only three times the horsepower of the Wright Brothers` plane, Alvin's plane is capable of cruising at nearly 100 miles per hour. I told Alvin that I had lived in Trempealeau nearly all my life and never knew that he had an airplane and a grass runway just outside of town. He said, laughing, "Well...I don't like much publicity. When people hear that you built your own airplane, well...some folks think you're some kind of a crazy fool!" Even as a kid, I empathized with Alvin. I understood. Many people thought I was kind of goofy the way I was always building and flying model airplanes (30 years later I still build model planes on occasion!). To me Alvin seemed like just another big kid fooling around with airplanes=E2=80=94the only difference was the horsepower, wingspan and payload. What a wonderful August afternoon out at Alvin's flying field, 32 years ago. The sun was hot and the summer air smelled of fresh-cut hay=E2=80=94and the possibility of flight! I got my pilot's license several years later in a 150-horsepower Piper Super Cub. On weekends I'd hop around to various fly-in pancake breakfasts, or over to The Big Show: the Experimental Aircraft Association's (EAA) Fly-In and Convention held at Oshkosh each August. At all of these fly-ins and at Oshkosh, in the midst of some of the world`s greatest designers, pilots and airplanes, Alvin held court, talking about his airplane and propellers. I've been away from airplanes for a few years, and I hadn't seen Alvin in many years. But recently I've been drawn back to airplanes and flying. Last=20year I purchased a set of plans for the Evans Volksplane_a proven, simple design that I figure even I can build. I also recently acquired a 1600-cc VW Super Beetle engine. With the right propeller I should be able to get a good 50 horsepower or so from it. (I know that my wife loves me because this past Valentines Day she stuck a wad of cash in my hand, gave me a kiss and said, "Happy Valentines Day! Go get that engine for your airplane!") I once thought about building a second Fledermaus, if only Alvin had made a set of plans. Ironically, on Saturday, March 9th, the very day that Alvin passed from this life=E2=80=94"Gone West" as World War I aviators would say=E2=80=94I was visiting a fellow over near Winona (Minn.) who is nearly ready to fly his homebuilt plane. It's a real Cadillac for a homebuilt. With a 160-horsepower Lycoming engine it will cruise at nearly 170 miles per hour. Like any bunch of pilots standing around talking about airplanes, our conversation got around to the=20subject of propellers and then, of course, to Alvin Schubert. And so we talked about Alvin and his self-taught skills as a propeller maker and airplane builder. I said, "Yep, I'll have to get over to see Alvin one of these days and ask him what propeller he recommends for a Volksplane=E2=80=94maybe he'd even carve a prop for me." On Monday morning, March 11, I saw the notice of Alvin's passing in the newspaper. I suspect that had I contacted Alvin several months ago, he would have recommended just the right propeller diameter and pitch, with a little finer pitch for more zip on those warm summer day takeoffs. More likely, Alvin would have taken the time to teach me how to figure out for myself the correct diameter and pitch for a given RPM, horsepower and airspeed. And then he would have taught me how to carve that propeller. Alvin was firm believer in self-reliance. Building and flying your own airplane is perhaps the ultimate expression of self-reliance. As far as I know, Alvin never lived anywhere but on his farm. Some might even say that he never really got out and experienced life. I disagree. Here on the ground what we do with our life is, for the most part, up to us. We can=20even drift along day to day with few serious consequences. But up there, how well you built your plane, how well you fly it, and the decisions you make, totally determine whether it's a successful flight or a disaster. Up there, life itself is in one's own hands. Richard Bach once wrote, "Why do we fly? We fly to know what it is to be alive!" Some say that Alvin never kept real close track of how many total flying hours he had accumulated flying Der Fledermaus and that he only kept track of how many takeoffs and landings they had made. I don't know if that's true, but it's just like Alvin. What difference does it make how many hours are spent=20aloft when what's important is whether you got off the ground in the first place, and even more critically, whether you were able to successfully land once again? Forever more, Alvin has now logged one more take-off than landing. I'm sure that he's out at some little flying field where the grass is always green, the sky is perpetually blue with "severe clear" visibility, and there's a light breeze that never varies from straight down the runway=E2=80=94always a perfect day for flying. I`d also bet that Alvin's probably got St. Peter and a squadron of angels cornered over at the hangar teaching them all a thing or two that even they didn't know about flying and aerodynamics. Maybe even how to carve a propeller. Happy landings, Alvin! ### ________________________________________________________________________________

As I read the regs, an inspector shouldn't withold signature for an annual inspection because of a lack of ELT. Its not his responsibility. If one is there, he should inspect it to make sure the installation is proper and doesn't interfere with operation of other installed equipment. But he cannot get written up for any violation for returning an aircraft to service without an ELT. On the other hand, the pilot could get written up for operating an airplane without an ELT as required under Part 91. ________________________________________________________________________________

Thank you for sharing Alvin with us. I have been too busy lately to read all of the posts or reply, let alone play with my Piet project. Inspiring stories like this one about Alvin are really good inspiration not to give up to the demands of today's busy world. My regards to you on the list, Thanks, John -----Original Message----- From: owner-pietenpol-list-server(at)matronics.com [mailto:owner-pietenpol-list-server(at)matronics.com] On Behalf Of TBYH(at)aol.com Subject: Pietenpol-List: Al Schubert, Al Kelch... I was pleased to see Alvin Schubert's name mentioned in reference to propeller carving and his book "How I Carve Propellers." Some of you my know that Alvin passed a few years ago. Following is a piece that I wrote shortly after Alvins passing for the Galesville Republican newspaper. At the time I was considering building a Volksplane, but once again, I came back to the Pietenpol instead. In fact, at Alvin's estate sale, I purchased the Pietenpol plans that Alvin had purchased back in 1968. Anyway, here's my tribute to Alvin... I should also mention that Al Kelch, who kept his magnificent collection of antique airplanes at Brodhead, passed away this last week on Sept. 21. See EAA's latest "Hotline." Last Flight: Alvin Schubert Remembered By Frederick Beseler, La Crosse, WI We lost a good friend when Alvin Schubert, rural Trempealeau, (Wis.) passed away on March 9th, 2002, at 85 years of age. Alvin grew up during aviation's Golden Age when pioneers like Lindbergh, Byrd, Hughes, Post, Doolittle, Earhart, Cochrane and Wittman blazed new trails across the sky-faster, farther and higher. "Pushing the envelope," as the test pilots say. They inspired a whole generation of kids like Alvin to get into aviation. Alvin was born in Genoa, Wisconsin, in 1916. His family later settled on the farm near Trempealeau where Alvin lived his entire life. I first encountered Alvin when I was a kid, growing up in Trempealeau. I was always building gas-powered model planes-control-line planes that go around in circles on the end of 40-foot long strings. My buddy, Claus Ryder, and I flew the planes in the small field below my parent's house on West Second Street. Around 1970 or so I decided to try free-flight modeling and so I built a balsa wood model of a Piper Cub that was powered by a little gas engine. Unlike control line models, free flight model planes require a large, treeless field from which to fly. One hot summer I pedaled my bicycle out of Trempealeau towards Centerville until finally I found a nice big, wide-open field just perfect for flying a free flight model plane. With a free flight model you set the rudder for a right turn, gas it up, start the engine and let her go. If successful, the airplane spirals upwards, circling left due to the propeller torque. Once the engine runs out of fuel and quits, it should glide slowly down, turning right in response to the bend in the rudder. Technicalities aside, you mostly pray that the model and all your hard work and the then expensive-for-a-kid $5.98 gas engine, doesn't simply fly straight away to the next county, never to be found. There was no danger of my Cub flying over the rainbow on that day. She took off and climbed away okay, but once the engine quit the model went into a nasty, ever-tightening spiral and bored straight down into the soft farm field. Test pilots call it "auguring in." While cleaning the dirt from the engine I noticed a farmer coming across the field, heading straight for me. No doubt it was the owner of the land that I was using for a flying field. I began packing up my tools, ignition battery and fuel as I was certain that he would chase me out of his fields. "Nice day for flying, isn't it?" he asked. "I believe that you need to bend the right aileron down just a little bit, and maybe bend the elevator up just a little_then she should fly pretty well!" I was amazed and astonished. First, he hadn't told me to get the heck off his land. Second, he spoke "airplane." But then I thought, "Who is this old farmer in the baggy coveralls, and how on earth would he know anything about flying and aerodynamics?" Appearances are deceiving. I soon learned that Alvin Schubert knew more about airplanes and aerodynamics than anyone else I ever knew. He was Valedictorian of the Class of 1938 at Galesville High School and he was forever and always tinkering with mechanical gadgets and engines. For example, Alvin had built a couple of tractors and then a working electrical generator for the family farm long before the power company came along. (Over the years I often wondered what this latter day Wright Brother would have accomplished had he gone on to college.) We got the model Cub fixed up and flying. He thoroughly enjoyed watching that little model fly. Standing there with his hands in the pockets of his bib coveralls, looking skyward as the tiny yellow plane floated upwards, Alvin said, "Well, you know, a model airplane obeys the same laws of flight that a full size airplane does." Alvin admitted that he had "monkeyed around with airplanes a little, now and then." He had done more than "monkey around." Alvin knew about flying and aerodynamics and how to build an airplane just as surely as William Boeing and Donald Douglas knew how to build airplanes. We walked over to one of his farm sheds. Alvin rolled the old weathered barn door open. Lo and behold, nestled among the straw bales was a real airplane! It was a trim little single-seat, all-silver plane that Alvin had designed and then built with his own two hands. It had a 21-foot wingspan and was powered by an early 36-horsepower Volkswagen engine, which was about the only thing on it that Alvin hadn't built from scratch. Even the propeller was designed and carved by Alvin. "I call her Der Fledermaus. Just step up right there, swing your leg into the cockpit and then you can sit in her," said Alvin. I asked if it actually flew. Alvin replied, "Well...yep...she flies pretty well...cruises along pretty fast on 36 horsepower. Well...I'm going to carve a new propeller with a little finer pitch to give her a little more zip on takeoff. Let's start her up." Before I could jump out, Alvin gave the propeller a couple flips and away she went, the little four-cylinder VW engine barking away through the stubby exhaust stacks. The wind from the propeller blew our hair. Alvin`s eyes sparkled. I was sitting at the controls of a real, running airplane! No disrespect to Der Fledermaus, but I recall looking through the Plexiglas windscreen and for a moment imagining that I was sitting in a World War II Spitfire or P-47 Thunderbolt. And then I remember thinking that I'd have to keep the whole experience a secret as I knew that my parents wouldn't care for the idea of their kid at the controls of a real, running airplane-much less a homemade airplane! That little plane truly was, and is, an engineering marvel. With only three times the horsepower of the Wright Brothers` plane, Alvin's plane is capable of cruising at nearly 100 miles per hour. I told Alvin that I had lived in Trempealeau nearly all my life and never knew that he had an airplane and a grass runway just outside of town. He said, laughing, "Well...I don't like much publicity. When people hear that you built your own airplane, well...some folks think you're some kind of a crazy fool!" Even as a kid, I empathized with Alvin. I understood. Many people thought I was kind of goofy the way I was always building and flying model airplanes (30 years later I still build model planes on occasion!). To me Alvin seemed like just another big kid fooling around with airplanes-the only difference was the horsepower, wingspan and payload. What a wonderful August afternoon out at Alvin's flying field, 32 years ago. The sun was hot and the summer air smelled of fresh-cut hay-and the possibility of flight! I got my pilot's license several years later in a 150-horsepower Piper Super Cub. On weekends I'd hop around to various fly-in pancake breakfasts, or over to The Big Show: the Experimental Aircraft Association's (EAA) Fly-In and Convention held at Oshkosh each August. At all of these fly-ins and at Oshkosh, in the midst of some of the world`s greatest designers, pilots and airplanes, Alvin held court, talking about his airplane and propellers. I've been away from airplanes for a few years, and I hadn't seen Alvin in many years. But recently I've been drawn back to airplanes and flying. Last year I purchased a set of plans for the Evans Volksplane_a proven, simple design that I figure even I can build. I also recently acquired a 1600-cc VW Super Beetle engine. With the right propeller I should be able to get a good 50 horsepower or so from it. (I know that my wife loves me because this past Valentines Day she stuck a wad of cash in my hand, gave me a kiss and said, "Happy Valentines Day! Go get that engine for your airplane!") I once thought about building a second Fledermaus, if only Alvin had made a set of plans. Ironically, on Saturday, March 9th, the very day that Alvin passed from this life-"Gone West" as World War I aviators would say-I was visiting a fellow over near Winona (Minn.) who is nearly ready to fly his homebuilt plane. It's a real Cadillac for a homebuilt. With a 160-horsepower Lycoming engine it will cruise at nearly 170 miles per hour. Like any bunch of pilots standing around talking about airplanes, our conversation got around to the subject of propellers and then, of course, to Alvin Schubert. And so we talked about Alvin and his self-taught skills as a propeller maker and airplane builder. I said, "Yep, I'll have to get over to see Alvin one of these days and ask him what propeller he recommends for a Volksplane-maybe he'd even carve a prop for me." On Monday morning, March 11, I saw the notice of Alvin's passing in the newspaper. I suspect that had I contacted Alvin several months ago, he would have recommended just the right propeller diameter and pitch, with a little finer pitch for more zip on those warm summer day takeoffs. More likely, Alvin would have taken the time to teach me how to figure out for myself the correct diameter and pitch for a given RPM, horsepower and airspeed. And then he would have taught me how to carve that propeller. Alvin was firm believer in self-reliance. Building and flying your own airplane is perhaps the ultimate expression of self-reliance. As far as I know, Alvin never lived anywhere but on his farm. Some might even say that he never really got out and experienced life. I disagree. Here on the ground what we do with our life is, for the most part, up to us. We can even drift along day to day with few serious consequences. But up there, how well you built your plane, how well you fly it, and the decisions you make, totally determine whether it's a successful flight or a disaster. Up there, life itself is in one's own hands. Richard Bach once wrote, "Why do we fly? We fly to know what it is to be alive!" Some say that Alvin never kept real close track of how many total flying hours he had accumulated flying Der Fledermaus and that he only kept track of how many takeoffs and landings they had made. I don't know if that's true, but it's just like Alvin. What difference does it make how many hours are spent aloft when what's important is whether you got off the ground in the first place, and even more critically, whether you were able to successfully land once again? Forever more, Alvin has now logged one more take-off than landing. I'm sure that he's out at some little flying field where the grass is always green, the sky is perpetually blue with "severe clear" visibility, and there's a light breeze that never varies from straight down the runway-always a perfect day for flying. I`d also bet that Alvin's probably got St. Peter and a squadron of angels cornered over at the hangar teaching them all a thing or two that even they didn't know about flying and aerodynamics. Maybe even how to carve a propeller. Happy landings, Alvin! ### ________________________________________________________________________________

Subject: IFR in a Pietenpol
I did a flight yesterday that I just had to pass along to the Piet group. I departed Cook Airfield to the Southwest, following the RR tracks. I saw 3 hot air balloons on the ground, ready to launch. I could see the flames going on and off every few seconds, so I entered a pattern overhead, at about 4 or 5 hundred feet, and blew a BIG smoke ring around the balloons for them to go up through !! The smoke ring hung in there very well in the no wind condition, till I completed the circuit, as the first balloon launched. It also served them to tell which way the wind was blowing up there. Then I picked up the Arkansas River, and dropped down to the deck, less than 100 feet above the water, and followed the river for about 30 miles. I saw lots of deer, and birds, and a beaver, but didn't see a single person along the entire length of the river flight. Gives the meaning to IFR - 'I Follow Rivers' !! Steep bank turns, maintaining 70 mph on the indicator, just below the tree tops for much of the flight, to follow the sharp turns in the river...Way Cool !! There are 3 places where wires cross the river, and 2 bridges, which I'll have to note more carefully on subsequent flights. It's a somewhat shallow river, with lots of sand bars to make an emergency landing. The river carries away lots of sand and silt, much to the farmers dismay. Down below Oxford, I pulled up out of the river bottom, and saw a crop duster just turn off the sprayer bar, and pull up vertical. Stayed out of his way, and made the return trip up the river. The balloons were all down in a different field, about 20 feet off the ground. They stayed very close to each other for their whole flight. I think this IFR course is going to be a regular !! What a Hoot !! Chuck G. ________________________________________________________________________________

I went out for a couple of hours today. A perfect calm, cool day so clear you can see forever. This week I had installed a new windshield. The wind had been hitting the top of my head coming over the shield. I cut this one 2 1/2" higher and a bit wider at the top. I was suprised at how much difference that makes. I cut down on the noise on the radio and is a lot calmer in the cockpit. Also, I posted my problem with the airspeed indicator a few weeks ago.

I agree Don. I have flown with Mystery Oil for years. Started using it in the Kinner radials then began using it in 0200's and C-85's. All with auto gas. I search for auto gas without ethanol though. The Mystery Oil is good in the crank case too. Lubricates better than just straight engine oil alone.

Subject: Hegy prop for a Corvair, and carb questions.
I have a chance to buy a Hegy prop for a Corvair engine for $500. Don't have the stats for the prop, other than it has never been installed. I've been told this prop is the correct pitch, etc. and perfect for a Corvair pumping out 100+ horsepower. Does $500 sound like a fair price? I'm not familiar with pricing and props for a Corvair. I've heard that Hegy (builder from Marfa, TX). Lastly, I'm contemplating installing a Corvair in a Piet. I was impressed with the Corvairs I saw flying at Brodhead this year. But, having had a bad experience with a Mosler 82X a few years ago, I'm reluctant to go back to a car engine. What I didn't like about the 82X (souped up VW with Scat Racing Heads, beefy crank and a hot camshaft) was a funky carb set up, no mixture control and ultimately NO RELIABILITY. In addition, the Mosler could not produce any power at 2,800 RPM and it really needed a reduction drive in order to get the power-band and prop working where they both were happy. (I tried a number of different props, and 2 different 82X engines, but the problem was with the Mosler and funky non-aviation carb. Is there a faithful carb with mixture control for the Corvair set up? What about dual mags for a Corvair? Thanks. S.B. ________________________________________________________________________________

you will need more info before you can decide on that prop.... someone telling you it is the perfect prop for a 110+ hp 'Vair means nothing. Yeah.. it may be the perfect prop for a Corvair.... a 54X60 is a great prop for a Corvair. it will absorb the power nicely.. but only for a plane that will cruise at 120+mph. It would be useless on a Piet. I doubt it would even get airborne with any level of safety. Also remember it needs to be a reverse direction prop (unless you go with a reverse camshaft) You want a prop that's gonna let you cruise around 75-80 or so at about 2400rpm. This is a ballpark figure as I have no direct experience... it just seems about right to me. You'll want a diameter around 62 to 66" with a pitch around 36 to 30" respectively. again... ballpark numbers $500 sounds good. I paid $550 shipped to my door from Tennesee prop. They custom build the prop to order. They use 1/16" laminations. There are 48 of them. Most prop makers use 1/2" laminations. more laminations means a stiffer stronger prop..... and some may think a more beautiful looking prop. You'll also want to make sure the prop is through-bored to allow the William Wynne safetyshaft to clear. Do you have William Wynne's Corvair Conversion manual?

forgot to address a couple other questions in your email as for concern about using a Corvair... just let that concern fade away. The Cirvair is practically an Aero engine. It's closer to an Aero engine than any other auto engine is... period. In about 8 months I'll have mine flying and you can come out and fly it/see it anytime you want. Dual mags can be done on a Corvair. I've seen it. It takes a tremendous amount of re-engineering and machining. In my opinion it's not worth it. If you convert the engine to William Wynne specs you will have dual redundancy in the components of the ignition that fail.... the coil and points. I have dual points in my distributor and I have 2 coils connected by a solid state auto coil switch. If one coil should fail the switch automatically changes to the other coil. Points never fail suddenly. It's usually a slow process that can be detected. 2 plugs are not needed in a Corvair like they are in an Aero engine. Look at an Aero engine..... large displacement... there's alot of volume to ignite. You need 2 plugs just to ignite and burn all the fuel... that's why a mag check gives you a drop in RPM. there's raw fuel not being ignited by the 2nd plug. Now in a Corvair where the volume is less there's just no need for a 2nd plug. Even if you did have dual mags with 2 plugs in each cylinder I doubt a mag check would show much of an RPM drop. Sure there's an element of redundancy with dual mags but you are getting the same redundancy with dual coils/points. The point of failure is usually not spark plug wires or the spark plugs themselves. And of course... there's the need for a battery to power the ignition with coil/points. yes.. if the battery goes dead so does the engine, but that's not likely to happen and there are ways to add in redundancy there if desired. There are thousands of proven flight hours with Corvairs built to WW specs. As for carbs.... you can't go wrong with a Marvel MA3-SPA. I am using a Stromberg NAS-3A1 with mixture control, but there is large debate on how effective the mixture really is on that carb.

I'm not sure what adhesive Tennessee Props uses. But I am very very happy with the quality of workmanship. Flight data still to be proven, but appearance and quality are top notch. They also put a nice Urethane leading edge on it (outter 2/3 of the blade) for an addition $50. Out here in the desert where dirt strips are everywhere it was a no-brainer to get that option. I ran it on the test stand up to 2900rpm and it tracked perfectly. I'll try to give them a call and see what they use.

It takes a tremendous amount of re-engineering and machining. In my opinion it's not worth it. If you convert the engine to William Wynne specs you will have dual redundancy in the components of the ignition that fail.... the coil and points. I have dual points in my distributor and I have 2 coils connected by a solid state auto coil switch. If one coil should fail the switch automatically changes to the other coil. Points never fail suddenly. It's usually a slow process that can be detected. 2 plugs are not needed in a Corvair like they are in an Aero engine. Look at an Aero engine..... large displacement... there's alot of volume to ignite. You need 2 plugs just to ignite and burn all the fuel... that's why a mag check gives you a drop in RPM. there's raw fuel not being ignited by the 2nd plug. Now in a Corvair where the volume is less there's just no need for a 2nd plug. Even if you did have dual mags with 2 plugs in each cylinder I doubt a mag check would show much of an RPM drop. Sure there's an element of redundancy with dual mags but you are getting the same redundancy with dual coils/points. The point of failure is usually not spark plug wires or the spark plugs themselves. And of course... there's the need for a battery to power the ignition with coil/points. yes.. if the battery goes dead so does the engine, but that's not likely to happen and there are ways to add in redundancy there if desired. There are thousands of proven flight hours with Corvairs built to WW specs. As for carbs.... you can't go wrong with a Marvel MA3-SPA. I am using a Stromberg NAS-3A1 with mixture control, but there is large debate on how effective the mixture really is on that carb.

Yes, the project is for sale. I haven't done anything to it and it has been sitting in the hanger on my farm under a tarp. I pulled the tarp off a few days ago and noticed the plywood sides on the fuselage are a little wavy and I suspect the wood went into "shock" after leaving a very, very dry desert climate in Arizona - moving to a very humid environment here in Central Texas. But once the fuselage is covered, it wouldn't be noticable. It is for sale minus the gas tank and motormount. The wing ribs, original rib jigs and much of the spare wood for the various wing parts have been in storage in an air conditioned and humidty controled office in my hanger. ________________________________________________________________________________

I did another river run yesterday. I came around a turn, and spotted 4 turkeys sprinting along a sand bar, like they were running from a mountain lion, or something. They were running like their life depended on it !! They just didn't realize that I posed no threat to them, but the sound of the loud engine must have given them visions of a growling predator. Big fat bodies, and spindly little chicken legs, kicking up a little puff of dust with each step, makes for a humorous sight for something in such a hurry. I think they were so scared, that they forgot they could fly !! Too funny. Chuck G. ________________________________________________________________________________

Hi Chuck, I remember well (and very fondly) of flights like that...slipping effortlessly over the cool, clear rivers of north Arkansas in my old Waco on my way to another barnstorming weekend in the hinterland of the midwest. I marveled that some animals were frightened by the rumbling growls of the old Kinner radial and others were not. Those animals (turkeys, chickens, ducks, etc.) that fear predators from the air (hawks, eagles, etc.) are fearful of large, winged, fabric covered wood and steel that makes the most terrifying sounds ever heard in the wilderness. Animals like cows and most hooved animals aren't bothered much with low flying predators (ie. man and his beautiful flying machines) because they are just another version of "man sounds" most domesticated animals are accustomed to. That is...unless that large-winged, growling predator happens to dive down at them and soar far too close by for comfort and then they often do, when callenged by man, and that is to flee for their precious lives...oh how I remember when...

I am using a Grand Rapids Technologies EIS 2004. It's a digital unit that monitors, rpm, OT, OP, manifold pressure, OAT, 2 CHT's, 2 EGT's, volts, hour meter, up/down counter, fuel flow, also has 2 aux channels for monitoring anything else you want. Small,compact, easy to read and has a ton of safety features. you can get away with OT, OP and tach only though. Keep in mind when you lay out the Piet panel.... the cabane X wires take up valuable panel space. make sure no instruments are in the way of them... I learned the hard way after making a panel that wouldn't work. you could try an Air/Fuel meter to aid in mixture adjustment.... something like that could be mounted in the front panel.

Subject: Engine Development Report
2004) Hi Bert, Congratulations on high speed taxi tests successfully completed. Interesting and exciting times continue. Glad to hear you survived the hurricanes and were able to help with the cleanup. Your friend with a possible interest in pictures of my engine project is a bright guy, willing to innovate and test. It was my pleasure to spend a little time with him at his airfield, just before Sun and Fun last April. I left with the feeling that I should have stayed another day to learn more. I particularly like his ideas on weight saving structures, "T" section rib capstrips, and cooling systems. He told me what happened in the crash that cost a life and totaled a great homebuilt. The passenger squirmed around in the front seat, using the front throttle as a handhold. In so doing, he damaged the pilot's control linkage and reduced power to idle a few hundred feet above the piney woods. Shoulder harnesses were not used, but might have greatly reduced the crash injuries. Years as a charter pilot have taught me that passengers are often credited with more common sense than they actually have. That is why passenger briefings are now the law for air taxi operations and a good idea for everyone else. Since I don't have a digital camera, conventional photo prints of my inverted Ford engine are all I have at present. It is hanging on my shop wall, supported on a mount attached to a Pietenpol Scout forward fuselage hardpoint mockup. --- Looks like a powerplant I might like to fly behind. --- Made in America! Shurely would be fun to have it for the annual gathering at Brodhead Wisconsin. Don't anyone hold their breath waiting for this to happen. There are good reasons why we don't see many inverted auto engine conversions. I'll touch on a few of them below: Oiling --- Oil must be picked up from a low mounted tank, circulated through the engine, and returned to that tank via a scavenge pump or gravity. A pushrod engine would be better than an overhead cam because return oil could run through the pushrod holes. Crank trigger ignition --- I set the entire system up in a lathe and was able to make it work minus the main power control module computer. The same pair of cylinders always fires first. Hand propping will probably work if you pre-rotate the engine with reference to a mark on the camshaft sprocket to take advantage of that fact. The vital parts of these systems can be sheltered behind the firewall, safe from the heat, moisture, and vibration that cause failures. Fuel System --- The factory injectors will be blocked open and pressurized with the factory pump. Mixture control will be via a cockpit controlled needle valve, bypassing fuel rail pressure to the return line. The throttle will have three basic settings: takeoff, cruise, and approach. Emergency fuel will drain from the wing tank to a calibrated orfice just downstream from the throttle valve. My emergency fuel system idea came from the book "Jungle Pilot" by Nate Saint --- recommended reading for those flying light planes through rough country. Happy landings, Mike Fish ________________________________________________________________________________

Subject: GN-1 project & Continental A-80 4 sale
I'm going to place my GN-1 project on Ebay in a couple of weeks but I wanted folks on the list to have first crack at it. You can see what this project looks like (minus the engine) by visiting D.J.'s website. I think he posted the info and pictures on March 12 and they should still be available for viewing. The GN-1 project has been in storage under a tarp at my hanger here in humid central Texas and I suspect the plywood sideboards on the fuselage went into shock going from an extremely dry desert climate (Mesa, Arizona) to what has almost been a tropical sweatland on my farm. The sides are wavy, almost undetectable ... and the laser cut metal parts I have that are unpainted need a light sanding because of a very thin layer of oxidation. I also detected what looks like some surface mold (dark spots) on a few wood surfaces (originally varnished) and it seems like a light sanding with 320 or 400 grade sandpaper would clean this residue off. This project comes with nearly all the ribs, built by D.J himself, as well as all the wood to finish the wings and D.J.'s original rib jigs. I am keeping the motormount and J3 Cub fuel tank, but everything else goes. I probably will also be selling my Continental A-80 engine, disassembled and now looking better than the day it left the factory. The case was worked by Divco ($820.42) and the accessory case was worked on to new factory limits by Drake Air Parts ($495.00) . I have a brand new camshaft (Sacramento Air Parts $500.00) for this engine and I recently purchased a nice yellow tag crankshaft from Aircraft Engine & Accessory ($650.00) that is 20 under with a new set of bearings ($4.25) . The connecting rods, tappet bodies and rocker arms were reconditioned at Aircraft Engine & Accessory to the tune of $906.59. I also purchased new rod bolts and nuts and cotter pins for $107.22 from Aircraft Specialties Services. I installed a brand new engine dataplate and had the old numbers professionally engraved (not stamped) and have all new cylinder base nuts, cover screws, MOH gasket set, all seals and gaskets and clamps from Fresno Airparts Company ($305.08) to go with the engine. The cylinders are currently undergoing a Cerminil process (best there is and I'll argue this point with ANYBODY) and they should be finished in about three weeks. I can't toss a figure out there for the engine until I have an idea what the cylinders will cost, but this will be a pristine engine with all yellow tags and receipts. The engine case is anodized and looks like a golden treasure trove and the new data plate makes this engine look like a million bucks (hey, maybe that's how much I should ask for it.) Keep viewing Ebay and I'll have this engine on the auction block in the coming weeks. Make a reasonabhle offer on the GN-1 project, and I might just sell it without going on Ebay.

I'll add that this GN-1 project was built by the same guy who built the wings I am using on my GN-1. The workmanship is very nice and I would consider it good and safe. It was built from the first day right here in Mesa, AZ. went through 3 owners but always stayed in our dry climate. All of the ribs and wing material are my stuff that I was going to use before I got my beautifully finished wings. I sold all of it to Sterling earlier this year. I used aircraft ply and Sitka Spruce on the ribs. All glued together with T-88. In fact the very same ribs Sterling is selling can be seen in the first entries of my construction log.

Subject: Scimitar Prop
I'm going to see if I can kick up any interest in the design of a 'Scimitar Prop'. I've brought up this subject in years past on this list, but had only limited interest. As we all know, a propeller absorbs the energy of the fuel burned in the engine, and dispenses it in the form of thrust. Whenever energy is transformed from one form to another, some energy is transformed to some other form which is lost to intent of thrust. Energy cannot be created nor destroyed...it's a fact of physics. Therefore, the more efficiently the 'Potential' energy of the fuel that is burned, can be transformed into thrust, the less fuel will be required to perform a given amount of work. A given fixed pitch prop is most efficient at a specific r.p.m., and a specific forward speed. This is why adjustable props came into play, and high performance airplanes usually have Constant Speed Props. Here is where the Scimitar Prop comes in. The blades of the Scimitar Prop will twist to a lower blade angle for the high thrust required for takeoff and climb, then once airborne and power is pulled, the prop unloads and flexes back almost to the blade angle it was carved at. Hence you have an adjustable blade angle prop, with No Moving Parts !! Pretty cool, huh? Wood is the chosen material for this design, because it will not fatigue, it's readily available, and it's relatively easy to work with. Here are the forces imposed upon a Propeller: 1. Centrifugal Force - Most powerful force, tends to pull the blades outward away from the hub. 2. Thrust Bending Force - Blade tips bend forward when put under a load. 3. Torque Bending Force - Blades bend opposite the direction of rotation. 4. Aerodynamic Twisting Force - Twists the blade at the aerodynamic center of pressure. Tends to twist the blades to High Pitch. 5. Centrifugal Twisting Force - The Mass of the blade, under a centrifugal force, tends to twist the blades to a Lower Pitch. 6. Vibration Force (Resonance) - Everything has a resonant frequency, according to the mass, and the location of the mass. A Scimitar design prop takes advantage of these forces to twist the blades to a lower blade angle for takeoff and climb, and then when in cruise flight and power is pulled back, and the prop unloads, the blade angle relaxes back to a higher blade angle, and you have a cruise prop. Steve Wittman certainly understood the potential of a scimitar design, as evidence on the wall of his hanger in Oshkosh. I still can't understand why all props aren't of scimitar design. With enough Research and Development, then mass production could easily bring the additional labor involved, down to a competitive cost. I have searched the library at Oshkosh, lots of web sites, and asked lots of people about scimitar props. By far, the best info I've found on it, is the couple of pages in Eric Clutton's book. I did, however, discover that the concept came about in W.W.I aircraft. The design showed potential, but what happened on several occasions was that in a dogfight, the lead plane would go into a dive, in an effort to escape the aggressor, and the engine / prop would overspeed, then the blades would begin to flutter, and disintegrate. You can imagine the vibration of a broken prop blade, and if power wasn't pulled and shut down the engine, it would then shake the engine right off the plane, and now, with a tail heavy CG condition, the plane would spin to the ground. Even if the pilot was able to shut down the engine in time, he was then a glider pilot...easy prey. I believe when you over-run the prop of a scimitar design, the aerodynamics are what cause the flutter. I have heard stories about how props de-laminate when using thin laminates of wood, however these props had the width of the planks in the conventional direction. The cause of these de-laminations could also have been the technique of construction. The big question, is if any successful props were built using the parameters that Eric Clutton set forth. I do not know the answer to that question. I still plan of building one, but haven't began construction, yet. The method of construction I would use, is laminates of 1/4" or less, bend each laminate in a jig, to match the 'S' shape of the prop, and use T88 exclusively, but to avoid squeezing too much of the adhesive out, by using either scrim cloth between the laminates, or glass beads in the mixture of epoxy. The type of wood would I'll use, is still undecided yet, but the type of types of acceptable prop wood is called out in the AC 43.13-1A. Now, the challenge of designing a reliable Scimitar Prop, using the mass of the blade to twist the blade to a lower blade angle for takeoff and climb, then back almost to the blade angles that they were cut at, when the prop unloads. The laminations would be perpendicular to the direction of conventional props, so as to achieve the dramatic arc of the blades, as set forth by Eric Cluttons design. I'm looking for any input, pros or cons, and especially if anyone is aware of an aircraft that has used this design prop successfully.

Subject: Re: Firewall question
Ol Tony B. was a smart feller. I would follow his recommendation. Here's my logic and I suspect Tony's, too. From the standpoint of what is a minimum safe requirement for certified airplanes... The FAA requires the firewall material be "fireproof". Their definition is that it must resist flame penetration for 15 minutes when exposed to a 2000 degree F flame. .016 stainless has been proven to meet this requirement. So, consider the wood on the backside of the heated steel. I am not sure of the exact temperature...but the auto-ignition temperature of wood is lower than 2000 degrees F. So even though the steel prevents flame penetration, the wood will burn due to the high heat radiating thru the steel sheet. So to meet the intent of the FAA regulation for wood-backed firewalls, insulation is necessary. Now, from the practical standpoint, imagine yourself with an inflight engine fire. Your first action should be to turn off the fuel. Hopefully your fuel shut-off alve is aft of the firewall (also a requirement for certified airplanes) and will thus be protected from heat. It is likely that the engine fire would extinguish if the fuel is valve is off. But theres a chance that your fiberglass resin nose cowl or smoke oil tank or something else is still on fire. Now think of your passenger up front and that nose fuel tank. If I am in that situation... The main thing I need is time to safely land the airplane and get myself and passenger out before the fire spreads thru the firewall to that fuel tank. So to answer the question of how thick the insulation should be.... I plan to do my own simple test. Take a 12" X 12" sample of the stainless material, backed with the insulation material, and wood. Expose it to a carburizing flame (the blue area is approx 2000 deg. F) and see how much time you will have to land the airplane before the wood ignites. Insulation is also helpful for keeping the fron passenger cool on hot days. -- Terry L.

Subject: scimitar prop
Date: Sep 29, 2004
Chuck; There have been many scimitar props built and flown. For a really interesting one, see recent Contact! magazine #76 on David Roe's highly modified Hummelbird airplane with "Aeromorph" super short-stroke VW engine and... scimitar prop. It's made of oak laminations (the hub and about half of each blade), with the tips and the outer half of each blade made of a composite material for resistance to erosion. I don't know that it is intentionally designed to flex in torsion to change the blade angle of attack, but I would suspect that it does some of that simply due to the scimitar shape and the inherent flexibility of the composite material. Warnke's "Almost Constant Speed" wood props have always touted this as a feature of the design... with a bit of torsional flexure to allow changing angle of attack at various engine loads.

I don't think Aluminum for a firewall is considered legal by the FAA, because it will burn. The Brits found the problem of aluminum's burning hot during the loss of one of their ships during the Falkland's war. Small missle set the aluminum on fire and burnt the ship. Missle damage was small, aluminum fire was a disaster. Re; the question of fibefrax, this is just aluminum oxide ceramic fibers "ceramic", I think just about any insulation material like dry fiberglass (silicon oxide ceramic) functions just as well. But bottom line, the "dope" used on the Dacron fabric will be burning real good, long long before an engine fire could burn thru 16-20 ga. galvanized steel over plywood. For those who'd like to save a little wt. forward of the CG, and live near the Boeing surplus store near Auburn WA, the surplus store sells titanium sheet about 20 ga., as scrap metal, cheap and very light weight. None of the ole store-bought certified ragwings have any insulation between the engine and fuselage, just a galvanized steel sheet. The FAA only requires as non-flammable firewall between the pilot and engine. I agree with an earlier posting- if the fire burns thru galvanized steel, and starts scorching the plywood, you've already got more problems than you'd want to be dealing with if still airborne.

The "Dope" won't burn if you use the PolyFiber process. It does not support combustion. Having lost a friend who burned up in an otherwise survivable crash due to the fabric burning, I consider this the primary reason to use Stit's PolyFiber process.

Subject: Letter to Greg, wing making
Date: Sep 29, 2004
Pieters, I just finished a letter to Greg Bacon, the fellow that bought my "Wounded Piet" After rereading it, it occurred to me that this information might be of use to some ot the newer members of the list who are maybe just starting to build a Pietenpol. I am sure that Greg knows most of this stuff, but I guess it won't hurt to repeat it. So with Greg's and your indulgence, I am posting it here where it might be of some use to those just "coming along" John Good Morning, Greg! You asked for information about how I built the wings of "Mountain Piet" and I am happy to do so, please remember that the wings were the first item I built and that was about 10 years ago. I don't think that I am senile yet, but my wife will tell you that my memory is certainly less than perfect! When starting to build the ribs, I checked the drawing that Pietenpol sent with the plans of the ribs against the coordinates that were shown. There was quite a discrepancy between the two and so I elected to layout a new drawing using the coordinates. These coordinates will not provide a smooth line, so you will have to make a batten and use it to connect the majority of the points and get a smooth line. After doing this I made a jig using the drawing and using the =BD X =BD inch cap and truss members as shown on the plans. The jig, which unfortunately I have now tossed, had small cams where needed so as to hold the rib members tightly against the blocks thus insuring accuracy. I then started to cut wood and used Engleman spruce, a locally available material which is a close relative of Sitka spruce except lighter in weight. The drawback to this material is that it has a number of small knots and you must choose the strips after milling which are free of these imperfections. I would think you could certainly use Sitka spruce (which is really expensive) or cedar as Charlie Rubeck uses just as well. I milled my own material, first planing the boards to an accurate =BD inch in thickness and then running these through my table saw into strips slightly larger than =BD inch. The grain for the capstrips was kept vertical to the wing span so there would be less deformation with the pull of the fabric. I then made up, without gluing it together, a rib in the jig using these strips and laid out templates for the gussets. I then set up the saw to cut out all the required components of the ribs. I cut the angles accurately, however, left the lengths a little long for a more accurate fit up later when putting them in the jig. These strips and gussets were then sorted out into a bunch of containers, coffee cans work fine. I made up a jig for bending the front of the top cap strips (four at a time) after soaking them in boiling water for a few minutes until they were flexible. They were then put in the jig and left overnight to dry, ready for the next days work. The 1/16 inch mahogany plywood gussets were sanded to remove any glaze so as to have better adhesion using T-88 epoxy. Actual assembly of the ribs went smoothly but I could only make about one rib a day because I let the epoxy dry completely before removing the rib from the jib. A tight fit of the rib members was done by using a disk sander and lightly touching the end of the precut parts to the sanding disk until I got the exact length needed. Gussets, of course, were only put on the top side of the rib in the jig and then the other side was put on the next day. The jig was protected from the adhesive by a piece of Saran Wrap laid over the top of the entire jig before putting in the rib components. These components were pressed down into the Saran Wrap into the jig as they were fitted and glued. This way avoided any epoxy getting into the jig and sticking the rib. The dimension that you cut slightly more than =BD inch should be above the capstrips so you have some material to sand down to the exact =BD inch of the capstrip. Before putting on the gussets I block sanded the entire side of the rib so that all parts were level with one another and then used an air hose to get rid of the sanding dust. Gussets were left a little high above and below the cap strips so they could be sanded down to be even with the cap strip later. The gussets were fastened with small 3/8 inch aircraft nails. I found that using a automatic (spring loaded) brad setter such as picture framers use, worked well. You might be able to get this at your friendly hardware store, but probably will have to find it yourself because the clerk won't know what you are looking for! I put a few strategically placed holes in the bottom of the jig, so that the part might be pushed out if it was reluctant to pop out by itself. When the gussets were put on the opposite side of the rib the next day, again I block sanded the entire side of the rib so that the gussets would lie flat. After the ribs were done, I made up a couple of false stub spars and mounted the entire set of ribs to these. Then it was possible to sand off all the protruding gussets and block sand the ribs all to exactly the same contour. When gluing, be sure to wipe all the surplus epoxy off of the joints, not to make them stronger or anything, just to massage your own ego! Spars are =BE inch vertical grain fir. There are, at least in my area some dealers that handle this material, and if you explain the project, hopefully developing their enthusiasm, they will let you go through their stock to pick out that most suited for you. I believe there is an EAA publication outlining the specs for the material you need, it's called "EAA Aircraft Building Techniques, Wood" I did not use the little wood wedges that Mr. Pietenpol shows on the plans, but simply cut the top of the spar to fit the angle. The cheek plates for fittings are made of 1/16 and 1/8 ply as needed. Be sure to sand the plywood before gluing with, again T-88 epoxy. The tip bow is laminated and you should be able to use the one on the salvaged wing, along with all the metal fittings. Just sandblast the fittings and refinish. Since we are in a dry climate here, I protected the fittings with just a coat of "Krylon" primer and then a topcoat of the same brand. Build yourself a table to assemble the wing on. It needs to be flat and level and build it long enough to hold both the wing and center section. You will build the wing on the table to the existing center section so that when everything is put together on the plane, it will fit with no surprises. I would suggest that you slide the ribs on the spar and before permanently fastening them down, that you put in the drag and antidrag cables and then adjust the spacing of the ribs slightly to clear them. You can see that I didn't do this and had to in several places put on some doublers and cut the truss members to avoid the wires. Also, even though the plans call for 1" nails to fasten the ribs to the main spar, these are too long. Instead, you only need to use about a =BD inch long nail, and be sure you drive these in the exact center of the spar (the neutral axis) only. This is to avoid weakening the spar. The epoxy is really the connection to the spar, the nail is only to clamp the rib to the spar until the epoxy sets. The leading and trailing edges use the same wood as you will use for the ribs. Block all the trailing edges of the ribs to the same height and cut the trailing edge to the same angles as the ribs, just a little larger than the finished part will be. You will need to scarf the trailing edge in some place, because it is doubtful that you will have a long enough piece to do it all in one shot. Now here is where I differed from the plans. You will notice that I made up 1/8 inch plywood biscuits and then used these to connect the trailing edge to the ribs. To do this I made up a jig incorporating a router and biscuit cutter that can be used on both the rib and trailing edge. I am lending this to you and will send it along with the plans that I forgot to give you before. Just return it when you are done. The leading edge is made up the same way as the trailing edge, scarfed and run through the table saw to the approximate angles as the rib and plans show. I made it just a little oversized and then rabbited the plywood on the top leading edge into the solid leading edge. You can see how this was done on the salvage wing. Don't put any support for the rear edge of the ply. Without any support, the fabric will pull down the ply between the ribs and then there is a smooth transition for the airflow. Bernie was one darned smart feller! I used Australian Hoop Pine, this is advertised in the magazines. Don't remember the thickness, but you can measure what is there and order what you need. This stuff comes in 5 foot lengths and will have to be scarfed together. I made up a jig to hold the proper angle and then used a drum sander on my radial arm saw to cut the work pieces. The leading edge is bolted in place and then hand finished with a jack plane and rough 80 grit sanding block to the final shape. I would suggest that you make a template of the leading edge of the good wing so that the leading edges of the two wing panels are the same. This will help to ensure that once you have the rigging right, the there will be less of a tendency for one wing to stall first. After the wing is assembled, be sure to "trammel" wing and adjust the cables to get the wing perfectly square. Use the "twang method" to get even tension. They don't have to be super tight, just taut with little strain on the fittings. Now its time to go to work with the sandpaper again. Work up to about a 220 grit and then varnish with "Varathane" or something similar. Put two coats on and sand between coats. Don't need to worry about a two part epoxy for finishing, the fabric cement you use later will dry quickly enough that it will not attack the finish. It might just soften it a little and really provides a better bond when cured. At this point, you should have a new wing, all varnished, no rough spots, connected to the center section and ready to cover. Pull the center section off, find a cool beverage and take your wife and kids away for a short vacation to make up for the time spent away from the family while building the wing. We'll talk about covering then. Cordially, John PS Made wine this last weekend from a new crop of California grapes. Won't be ready for a couple of years or more, but will enclose with the plans and router jig, a bottle of our 2000 Petit Sarah. I think you will enjoy the label! ________________________________________________________________________________

Rick, There is a requirement for this. It's somewhere around .016", but I forget. Just remember it can't be aluminum.

----- Original Message ----- From: "Rick Holland" <at7000ft(at)gmail.com> Subject: Re: Pietenpol-List: Another firewall question ============================ Rick, Fluting pliers are just the ticket for shrinking the leg of the angle which fits against the firewall. The screws that hold the angle to the firewall are then located inbetween the flutes. The flange of the angle that faces away from the firewall is then smooth and you can easily fasten the cowl to it. To make the cowlings, first roll them the the radius that you need, then use a sheet metal brake to make the crease on each side so that the angle of the creased section is the same as the fuselage side. Then you can use brass inserts threaded into the strips that hold the fabric away from the plywood sides to provide for machine screws to fasten the cowlings. Be sure that the "stand off strips" are made of a hardwood and of sufficient width to receive the brass inserts.

Subject: Engine mount fittings and your firewall
Terry and Group--- One thing that can bring tears to your eyes is not having enough length on the metal ears of those fittings that stick out thru your firewall that accept the bolts to hold your motor mount on. (I guess the Ford has the ash bearers, but the bottom are the same on all. I made the ears on those fittings about 1/2" longer than the plans show because I knew by the time I added the firewall, the insulation, and the metal firewall that it might be a tough fit to get the engine mount back far enough to make those bolts slip thru the holes. As it was I just had enough room. That 1/2" insulation will compress some Terry but you'd be fine to "peel" a thinner layer off of it if it is the kink I am thinking of. You know how tight Bernie was with those fittings.......some of them as designed just do not fit or work at all. I would bet that Bernie just laid a piece of plywood over the front as a fire wall with some shellac on it. One thing that really helped me out was gluing the firewall plywood on last. It was the last thing I did before covering. It was all made up, test fit, had all the lines/service holes in it.....but only screwed on and off many times before the final gluing.

Subject: on fire during a flight in an open cockpit
The most disconcerting thing (and enjoyable) thing that happens when flying an open cockpit low and slow is that you can smell lots of things going on at ground level like fires. When someone is burning a tire or you go over a town with a plant that is putting out the scent of something burning, it always makes my mind race to "what if that is me ?" Sometimes you know right away because it smells like a camp fire or mowed hay or.......manure even, then other times you can't see a smoke cloud and you smell it-----something burning. The very first thing I do is an s-turn and look over my shoulder to see if I am trailing smoke. Once I see I am not, I relax again. (and engage the autopilot that is coupled to my inertial navigation system) Mike C. PS-- those of you who ride motorcycles know what that experience is like of smelling things much more easily than when riding in a car. You can smell steaks on the grill, dryers going with fabric softener, a good cigar, and even once in a while a Harley chick with some nice perfume ahead of you. ________________________________________________________________________________

One of the guys at the airport gave me about 4 gallons of the smoke oil that the Pepsi Plane used in the airshow put on at Mc Connell AFB. It looks and feels the same as baby oil, but it sure doesn't smell the same !! I always do a Smokin' Take Off. Get the tail up, hit the button, make a vortex curl on each side of the smoke when the wing grabs some lift, and leave it on till I'm past the crosswind leg. I did a flight today, a little over an hour, where I blew circles above 3 different friends houses, and smokin' flyby's at 3 different airports. I approach the airports extra high on short final, then pull power down to about 1300 or 1400 rpm, and put it into a sharp slip, with a very steep approach, keeping the airspeed up to at least 65 mph, and straighten 'er up after I cross the numbers. The smoke all blows completely under the fuselage, and makes a straight line off runway heading, then a low fly by about 60 mph, then add in full power about 3/4 of the way down the runway to build airspeed up over 70 mph, and gently pull the nose up into a relatively steep departure, keeping a close eye on the airspeed, never letting it drop below 60 mph. When I turn around to check out the trail, the smoke hangs in 3 separate straight lines. Pretty Cool !! I'm going to hold the camera backwards for a shot of it, next time I think of it. The other day, I landed using the final rays of sunlight, and I was back taxi on the grass during the perfectly calm evening of playing in the pattern with a J3. I put in over 1000 rpm, dragging the brakes with the stick back, and hit the button. Plumes of smoke surrounded the cockpit, and I couldn't see anything behind me. Drug the smoke almost all the way back to the hanger. In the perfectly calm air, the smoke hung there for at least 15 minutes !! It looked like ground fog. I have my own weather maker !!

The simplest (and most accurate) is to level the plane with EMPTY tanks but ready to fly (leave "unusable" fuel in the tank). Weigh it and determine the CG location. Then put yourself in the cockpit (in what you would wear to fly, no cheating! Most of us seem to use our weight just before getting into the shower but not many of us fly "buck neked". If you do, and if you aren't a beautiful under 30 female, I don't want to know about it.) and weigh it and determine CG again. Next, put full fuel in and repeat the process. Don't forget to MEASURE THE GALLONS OF FUEL YOU ADD! Last, put your backside in the cockpit with the full fuel and do it a fourth time. Most will think this is excessive but, you wouldn't believe how often the numbers you measure WON'T match what you calculated they "should be". Your seat probably isn't exactly where you think it is, your tank probably doesn't hold exactly what you think it does, the tank probably isn't exactly where you think it is and none of our bodies CGs are where we usually think they are. Once you have the location of the CG on the fuselage (for each condition) you need to measure where it falls ON THE WING CHORD. No matter what ANYONE ELSE TELLS YOU, all that matters is where the CG is on the wing NOT THE DISTANCE FROM THE FIREWALL, THE PROP FLANGE OR ANY OTHER PLACE. THE WING! JUST THE WING! ONLY THE WING! There are some guys out there on some of the groups that have stretched tails and noses and moved wings and think the CG should still fall at the same fuselage station. I have 30 years as an aerospace engineer and you have GOT TO TRUST ME, those guys are going to kill someone. Keep the CG in the limits ON THE WING. You have to be in the limits for all of the conditions you measured. If you aren't you need to move something to make sure it is, even if it requires ballast. You haven't had a thrill till you burn fuel from a nose tank that puts you in an aft CG condition and fly into turbulence. Weight transfers from your body to the seat FAST but it doesn't move the CG to help you, it just ruins the seat. If you need help with the math or in set up methods for measuring, just ask, but this ISN'T a place to scrimp. An incorrect CG can and will kill you.

Hank, I rarely fly nekkid, but I sure would like the math procedure and I would like to know the "limits" of where the CG falls on the wing chord.

Here's 4 programs that I used. They are the 4 different scenes that you will run into in a Piet. Worst is pilot only with low fuel, and best is full gross with full nose fuel. Use the one you want.

Your warning is correct. You need to locate the CG on the wing. However most use a convenient point on the plane as their reference or datum. The distance that the leading edge is from that datum will be in the computed distance to the CG. The actual CG can be referenced by subtracting that distance. Most designers specify a distance from a datum instead of the distance or percent of chord. Either method IF done correctly, will work. For further details, check AC 43.13-1B There is a complete method set up by the FAA for weight and Balance.

Hank, Excellent detailed procedure. Couldn't agree more with the pros and cons of using anything but the LE of the wing for determining CG and limits. Adding and subtracting ARMs to do moments, isn't brain surgery. Some guys like all positive arms, but all homebuilts are different. Second issue, the purpose of homebuilding is to LEARN. Learning about CG, MAC, materials limts in construction, contruction techniques is the reason for homebuilts. It is especially a problem when an non-builder pilot becomes PIC test pilot of a newly bought toy someone else built from scratch. Now to the question of Larry. Wing Chord- and CG. Just about all straight wing (verus swept backward like a canard pusher type), I've seen use 20% of chord for loaded forward CG limit max. (this depends on the elevator authority available to keep the nose in the air at flare), 32% of Chord for loaded AFT CG limit. So when you run low on fuel, and you're 300 lbs, have you slowly slid past the AFT CG limit on your wing as you burnt off fuel, therefore going into a tail heavy unrecoverable stall, or do you do your homework about MAC and CG limits before you start your engine? Every homebuilder should build there own CG envelope based on Hank's excellent procedure outlined below. Do the flight test work on the plane, using a guideline of loaded configuration - forward CG max. 25%, Aft CG of 28%, in test loaded configuration. Maintain this very narrow CG envelope test area until you can safely expand the loaded configuration to the max of 20% forward and max. 32% aft. and max takeoff weight configuration. Any of you aerospace wing design Engineers can jump on these % numbers with other hard data or facts, I'm only a reporting these numbers from observations of many types of homebuilts with straight wings. Every homebuilt airplane is going to have a different looking CG envelope. Maybe sloped forward at max. fuel and max passenger wt, or maybe sloped backward to account of fuel burn-off. This is something you learn about homebuilts just like the fuel plumbing or wiring. Every Pilot, by default is a TEST pilot on a homebuilt. You gotta learn or you'll burn.

We have weighed the plane with empy fuel but full radiator. Does anyone have a simple procedure for determining the CG, with my fat rear in place and full tanks? >> Larry, CG has always been a popular topic of Pietenpol aircraft. Last year at Brodhead, Doc Moser pointed to the last two digits of my registration number and said "Chuck, that's the most aft CG I've ever seen !!" If your plane is in the same configuration as the previous owner, I can all but guarantee that with you in the cockpit, you will be AFT of the aft limit of the Center of Gravity...a dangerous place to be. Pietenpol's are notoriously tail heavy, probably due to the fact that Bernard Pietenpol weighed about 160 to 170 lbs. B.H.P. called out the center of gravity range to be between 1/4 and 1/3 of the Chord. This translates to 25% to 33 1/3% of the chord. The chord is 60", so your C G range is between 15" and 20" aft of the leading edge. The aft limit called out by BHP has always concerned me. Very few aircraft have an aft limit that far back. I believe it is due to the undercambered airfoil. This airfoil has a LOT of negative pitching moment, allowing the aft CG limit to be so far back. If your Pietenpol does not have the airfoil called out in the plans, you CAN NOT use the aft limit called out. If you look at the last few pages of the 'Pietenpol Operation Manual' that I sent you, you can see how to compute C G with paper & pencil. Simple math, but very unforgiving of mistakes. Do the math three times !! Chuck G. NX770CG ________________________________________________________________________________

Either Jim is one super artist.... or powdercoating is waayyy cool..... or BOTH!! I think its both! :) We did my rudder pedals, both control sticks and the tail spring assembly, and some other miscellaneous parts. They turned out georgeous. I'll post some pictures soon. Thanks Jim, Julia, Ethan, and Ben for a great time, wonderful hospitality, and for the help. What a boost it is to have friends like you. Thats what this group is all about.

There is something about building a Pietenpol that waxes poetic in the heart of a man. The feel of freshly sanded spruce cut with great care from large slabs of two-by-six chuncks of wood just wanting to someday be a Pietenpol. The mounds of sawdust on the floor, the fresh scent of "new wood", the acrid but plesent smell of epoxy...all that reeks of airplane! The painstaking hours of stooping over a crude rib jig, carefully mitering small sticks of wood to fit tight and not quiting until they all fit tightly together, then cutting rounded gussets by the droves and miticulously sanding one side until the unwanted gloss is all off knowing that once this surface is mated to a piece of rib the joint will be stronger than that wood itself. All these pieces of wood packed with a goo so sitcky that a fly trapped in it would never be free again, and the gussets and sticks matted together with glue all pounded tightly together with small microscopic nails driven with love and determination hoping that one day this rib will become the wing of a mighty airplane that will take the builder/pilot on long flights over mint green meadows floating among cotton white clouds painted upon an azure blue sky...these are the dreams of a man who started out with large two by six chuncks of wood fourteen feet long. Happy building my friends, and may all your aircraft be as beautiful and as graceful as the work you poured out on her and may she always take you to places that only pilots who build their own airplanes can ever go to.

Chuck--- a few years back this great older guy at the airport and I were chasing each other around in the sky with him in his J-3 Cub. I could not shake this guy off my tail, even tho the Piet can turn on a dime. It was like I was being followed by Eddie Rickenbacker. I looked back and Bob was right behind me, about 200 feet back. I hit the smoke oil and flooded his view with thick white smoke and you should have seen him bobble and rock to get out of that so he could see. I'm sure his cockpit was filled with the airshow aroma of Texaco Canoupus #13 Oil. When we re-grouped after our fun he told me that had we been flying armed airplanes, that my smoke would have been black and I would have been dead. How true. Made me respect the flying skills of a 72 year old guy like you would not believe. Mike C. PS-- Chuck--- on a calm eve. before sunset, set yourself up in cruise flight and hit the smoke, pull up hard left. Repeat pulling up right, and look over your shoulder. Sometimes the vortex action can swirl the smoke into smoke rings that stay put long enough so that if you are fast enough you can do a 180 and fly back thru them ! ________________________________________________________________________________

Chuck--- EXACTLY ! Last Sunday I was giving rides at our EAA pot-luck and there were three other planes doing the same thing and I wish they had smoke too. I do the same when entering a pattern--a puff of smoke here and there does not hurt to be seen and avoided. On the g-forces, I don't do anything wild either, but a firm pull-up left or right sometimes produces some neat swirls behind you w/ the smoke on. I don't like to pump the oil at low power settings because it does not vaporize completely and my gear legs on the right side get coated with un-burnt oil.........and you know what they say, " unburned smoke oil is a terrible thing to waste" :) I can it "liquid fun".

Mike, I agree with you that "smoke" is fun and can even help make you visable to other A/C at times. After five years of professional airshow acro in a highly modified Pitts Special with two different smoke systems (the Corvis oil-pumped to the exhaust manifold via an electric fuel pump from a five gallon tank in the top wing, and a second comprised of smoke canisters of different colors of smoke bracketed on the wing tips) that you should never burn smoke at low RPM's. In the Pitts, that was a 1800 rpms. That is to avoid a fire that could be (and has been) fatal. Just be careful and keep the unburned oil cleaned from the fuselage to prevent build-up. I think the smoke systems are neat, but there are some hazards associated with them. But also there are some hazards in flying in general. Always fly safe and "happy landings...always".

Corky, In 50(+) years of messing around with A 65-8 Continentals, I have never seen a right hand thread on the tachometer drive; they were always a left hand thread indicated by an arrow. Possibly the threads are corroded, making it difficult to break loose. Carefully heating the rear case (I think it may be a magnesium alloy casting) and chilling the tach drive adapter should help. Also, a penetrating oil might assist you. Good luck! Graham Hansen (Pietenpol CF-AUN in sunny Alberta) ________________________________________________________________________________

Don't feel bad. When I sent my case and accessory case off to DIVCO and Drake Air (respectively) Drake almost totally screwed up my tach drive housing. They almost succeeded in striping the tach drive when the turned it counter-clockwise trying to remove it. Mine (off a Continental A-80) unscrews counter-clockwise. Try shooting some heat to the tach drive and if you can, place some ice on the accessory case, then turn it counter-clockwise. It will help if you can soak the joint for a few hours with a product my dad has used for many decades called "Knocker Loose" before attempting to remove the tach drive. Corky... did you get my DVD and look at it yet? By the way, my cylinders (having a fresh nickle process) will be fresh from an overhaul in Fort worth in about 4 weeks.

Subject: Smoke System
This smoke system seems like a lot of fun. How does it work? Is it easy to build and fit one? Or do you just buy one to bolt on? regards Tug Tug, My smoke system consists of an after-market windshield washer pump and tank, plumbing to each exhaust pipe, and wiring to the switch on the power lever. I isolated / mounted the tank on the upper left motor mount tubing, with a couple layers of rubber strap. I routed the clear tubing to a Tee fitting secured in rubber, to the engine mount, then used 1/8" brass tubing to each of the fittings in the exhaust pipes. I laid out the route of the tubing, marked the pipes, and removed both exhaust pipes. I cut a 1/8" pipe coupler in half, radiused each half to the radius of the pipe, and oxy / accy welded them to the aft pipe of each side. After welded, I drilled one #60 hole through the exhaust pipes. I placed these holes toward the bottom edge of the fittings, theorizing that if oil would lay in there it would gum up. The switch is a push on / push off button, that is mounted right to the throttle handle. This location allows me to work the smoke without taking my hand off the throttle. I originally thought it would only smoke good at full power, but came to find I don't need much over 1/4 throttle to Smoke 'Em Up !! I can smoke 'em while taxiing, without any problem !! My exhaust pipes point down and away from the fuselage, and even when all the oil doesn't vaporize, the fuselage hardly gets anything on it. I have a couple of squawks on the system, that I have taken care of. 1.) I mounted the tank at about the same level as the fittings on the exhaust pipes, and it always dribbles out the pipes, with a little bit of smoke as a result. Over a period of a couple of hours, it will drain the tank, but I usually 'Smoke em up' before that happens. 2.) When I ran the tank empty, and refill it, the pump would cavitate because of the way the line ran from the bottom of the tank to the pump, and I would always have to prime the pump, by blowing in the top of the tank. I got some strange looks from folks, while I performed this operation !! 3.) The tank was too small. It only was big enough to do about 3 smoke runs. I would like to put about a 5 gallon bucket up there on the firewall, but I don't have enough room !! 4.) I had to remove the top cowling to re-fill the tank. I'm building a new tank out of fiberglass / West System resin, with a fill tube out to the right side of the cowling. I'll mount it lower on the firewall. This will take care of all the squawks. 5.) I now have been using the new smoke tank, but I have a small leak in the tank. I used West Systems resin for the fiberglass tank, and evidently I didn't get the seam sealed up good enough. I've never had that problem when I used polyester resin, but it kicks very quickly. The West System gives some time, but it is also quite a bit more expensive. After the warnings about the stuff catching on fire, I'll be repairing the tank before my next flight. Chuck G. ________________________________________________________________________________

Subject: Re: serious smoke advice (now Tomahawk)
The first airplane I purchased was a Tomahawk, back in the 1980s. I loved that plane. Although I learned to fly in a Twin Bonanza Excalibur, the Tomahawk was a darned good trainer. If you stalled the Tramahawk, and went into a spin (many folks did, and sometimes instructors and their students didn't recover and a few augured in.) You had to be on your toes, literally and figuratively. It helped if you had spin training in something tame like an Aerobat 152, and then tried spinning a Tramahawk when you had developed some kind of skill. Also, some folks got buggered in Tramahawks because the tail shook like hell during the stall and the break could happen very suddenly, pealing off to the left or right very fast. When the tail shuddered, it sounded like the thing was breaking up in mid-air and Cessna pilots not accustomed to this often would land, wipe their be-hinds and go back to their predictable and docile 152s or 172s. For those who originally trained in a forgiving Cessna or other old-lady airplanes, sure, they lament the Tomahawk, but in fact it's like guys who drink Light Beer or Real Beer, depends on what your taste is. The Cessna is less filling, but the Tramahawk is better tasting. Now, let's talk about ribbon cutting, upside down in a Decathalon... that's a serious pucker factor I won't soon forget, not to mention sore shoulders in a harness... Makes the stall in a Tramahawk look very tame. S.B. ________________________________________________________________________________

So........ today was an awesome day. I finally got the engine running smoothly on the airframe. Firewall forward is complete. Fired it up an all was well. Oil pressure was good, oil temps kept cool. CHT's within limits.... so.. here I have this 95% complete fuselage with engine running... brakes work, tail wheel hooked up.. how could I resist some taxi tests. I employ my neighbor (who happens to be an airline pilot) to wach for cars and spectators on my street. I then pull it out on the street and start some taxing.... did about 4 runs up and down and slow speed, maybe 8-10 mph. Then the neighbor kid comes out... I think he's about 9yrs old... he had a smile from ear to ear just watching. I shutdown and yell over at him "Brady.... go ask your mom if it's ok if you take a taxi ride in the Aircamper" he darts inside like a lightning bolt. 10 seconds later he comes outside... " She's says I can go! yeeeehawww!" I help him into the front seat, buckle him in with the 1969 Brantly B-2 Helicopter seat belts I have installed. I tell him he can move the stick all he wants but don't play with the throttle lever. We then commence to driving up and down the street about 4 times. he loved it... me too! Then all the sudden the fun came to a stop when I look behind me to see a Mesa Police Dept. car behind me with it's lights on PULLING ME OVER!!! it was hilarious! I shutdown and hop out. the cop is the nicest guy and he's laughing saying he's never pulled a plane over. He looks the plane over asks the typical questions and then politely tells me I need to put the "toy" away cause I'm on a city road and my plane is not exactly licensed to drive on it. I tell him thanks and I push it into the garage. What a hoot! My first passenger ride and a cop pulls me over.... how funny!

Subject: Re: serious smoke advice (now Tomahawk)
A very dear friend of mine by the name of Bob Sears introduced me to inverted flight in a Decathalon. Bob was a commercial pilot and CFII and the adventurer I took my flights into Mexico and Central America. (Plenty of stories for these trips, no time to explain.) Bob used to fly in various air shows in the late 80s and early 90s and actually flew in a few events that some really topnotch performers appeared in. The first show I went to with Bob was in Lakeland, Florida, where Bob flew a Super Viking as the Avenger. He developed a routine especially for kids and was actually dressed up like a super-hero. After his routine in the Super Viking, he would hand out pictures and autograph them for hundreds and hundreds of kids. He introduced me to a handful of airshow pilots and among the most impressive (personally) was Patty Wagstaff and her husband. Bob had four airplanes he flew in different airshows, to include a 300 HP Pitts Special. I never saw anyone do in a Pitts, what Bob did and he was a legend at the ABQ Balloon Festival when he flew is Pitts upside down in a drainage canal. From the audience perspective, it was quite alarming to see him do this because he appeared to look like he flew into the ground. The audience could not see the canal and it was startling to see him disappear into the canal. He also flew his Pitts upside down through a WWll hanger near Monahans, TX. The hanger was very large and part of a training base for B-17s. It was abandoned and simply out in the country as a vacant building. I'll try and find a copy of Bob flying upside down through the hanger so I can scan it and send it out on e-mail. The least impressive upside down flying was done in his Decathalon and he practiced his routine at his (Sears, DFW Sectional) ranch, not too far from my place, (5TA6, Knot-2-Shabby, San Antonio Sectional). I proudly can say I never blew chow on the three occasions I did with him in his Decathalon when he was practicing out here in the boon docks, but it hurt like the devil. The harness really digs in to the shoulders (at least for me, when holding a camcorder). Wanna see my video from inside the Decathalon, upside down? I still have a copy around here somewhere. He clipped ribbons on poles as he flew upside down about 25 feet off the ground. Bob also had a Yak and he was working on a routine for that, but be became ill from lymphoma and he died in 1995. I think had Bob not become ill, he would have made the airshow circuit in a very big way. His flying skills were extraordinary and he made friends where ever he went. He really made an impression with kids as the Avenger in his Super Viking and one interesting note for Pietenpol folks... Bob especially liked the Super Viking for aerobatics because it was made out of wood and gave him the strength he needed for the budget he had in finding an airplane that looked cool for kids. A black airplane with red and yellow lightning bolts. S.B. ________________________________________________________________________________

Subject: Prop - Kevlar Tipping and Fiberglass Wrap
In a message dated 10/6/04 6:58:47 AM Central Daylight Time, steve(at)byu.edu writes: << Where do you get Kevlar for the LE? I've carved mine and been flying it with just varnish till I'm sure I like what I've got. Now that I do, I'm ready to protect the le and rebalance. >> Steve and all, This is another one of my typically long posts, so fair warning !! Kevlar is the most abrasion resistant of the composite materials...that's why bullet proof vests are made from it. Using Kevlar for the leading edge was my idea. I purchased the unidirectional Kevlar from AS&S. It comes 12" wide, buy it by the foot, but you need a 4 foot piece. It has all single flat strands of Kevlar, held together with little fiberglass strands every couple of inches. It is some tough stuff, that will quickly dull a pair of good scissors if you cut a lot of it. After all the carving is done, and the prop is balanced, the wood must be cleaned thoroughly to remove all dust and skin oil, with alcohol, and allow an extended period of time for all the alcohol to evaporate. Don't touch the wood with bare hands after that. Measure the length on the blade you need to cover the outer 2/3 length of the blades leading edge, and up half way around the rounded tip. The length of Kevlar must be identical for both blades, for balance reasons. Wearing surgical gloves, lay out a 3/4" width of Kevlar for each blade, on a clean flat surface, and cut to length. It's kind of difficult to get the Kevlar to stay where you put it, because it always wants to curl up, and go crooked. I use scotch tape about ever couple of inches to make it obey. Leaving the tape on the Kevlar strands helps control the fibers, as well as allowing you to stow the piece of material while you apply the Polyester Resin to the area on the leading edge of the blade. Kevlar does not readily soak up the resin, so you have to use plenty of resin, and kind of work it in after the Kevlar is applied to the resin. The scotch tape now holds the Kevlar fibers stay where you put them, as long as there is no resin where the tape sticks to the wood. Patience is order of the day, here. You can only do one blade at a time, with the prop secure and the leading edge you are working on pointing up. Mask off each face of the prop, leaving at least 1/2" of wood showing wider than the 3/4" wide Kevlar, to catch the inevitable runs in the resin. Have everything ready, and a plan in your head, because when you add those drops in the polyester resin and mix it up, you have but minutes to get the Kevlar on and in place. I never use quite the full amount of hardener, to give me a few extra precious minutes. If you don't get the 3/4" wide piece on straight the first time, just wait till after it kicks, then pull the piece of Kevlar back off and discard it, and start over. You'll have plenty of Kevlar material for several re - do's. Now you have the Kevlar on both blades, remove the scotch tape, sand and feather the edge of the resin down, but don't get into the strands of Kevlar. Don't use too coarse of sand paper, or scratches will show in the final product. Make sure the prop is clean, and the work area is clean, and lay the prop down on the flange surface on top of a block, to space it up off the table, to prepare for the lightweight fiberglass application. Cut four pieces of fiberglass big enough to cover and overlap the leading and trailing edge, and the tip. Lay newspaper under the blades to control the resin that is going to drip off the blades. The fiberglass should go from the root, almost to the hub, and extend the full length of the blade. This protects the wood, stabalizes the moisture content in the wood, and keeps the Kevlar from coming off with centrifugal force. Do one blade face at a time, and make sure you have 100% saturation, and have a smooth surface. Once the fiberglass is saturated, the fine cloth completely disappears, and the only thing you see is the yellowish green color of the Kevlar strands. Again, speed is the key, once the hardener is added to the resin. Keep it straight by a dabbing action with a one inch paint brush with half the bristles cut off. Use cheap bristle brushes, and discard the brush after each application...it's just not worth trying to clean it. Allow the cloth to overlap the edges, and trim them off with a razor blade after it sets. Finish sand to blend the edge of the fiberglass. Flip the prop over and repeat the process. After the resin cures for a few days, give it a beautiful glossy shine with a couple of coats of Ace Spar Varnish, gloss #16375. Use the varnish step to attain a final balance, by adding an extra coat to the light blade. To build the 3 props that I have done so far, my main instruction was talking with experienced folks in the area of building propellers. I also used the drawing of the prop for the Model A engine, that Orrin Hoopman drew up dated 3-3-33. It is 76 X 48, but I think it certainly has too much pitch for the ol' Model A engine. I think Ken Perkins runs a 76 X 42, which allows the engine to run up to the rpm where there is quite a bit more power. My other main instruction is referenced on this drawing to the book by Eric Clutton called 'Propeller Making for the Amature', available through the EAA. The Hoopman drawing, and the book by Clutton, show how to use an X Y chart to determine the blade angle at each 6" station. His book is the only reference I've ever seen to a True Scimitar Prop design, which I plan on building. Although I still haven't found anyone who actually built and tested one, and the theory sounds good, the challenge would be in the design location of the mass. With the blade installed and torqued, the blade track must be well within 1/8". I try to get mine within 1/16". That's how I finish off my bug whackers !! Questions ?

Subject: Aileron rib build questions
Date: Oct 06, 2004
From: "Textor, Jack" <jtextor(at)thepalmergroup.com>
Hi guys, Only found two comments in the archives on this one, looking for some additional comments. I'm building the 3 piece wing and currently building the ribs. I want to plan correctly for the aileron ribs. It appears I will need to "modify" 6 ribs for each aileron. I plan to build the ribs the same as the rest and make the cut =BC inch behind the last upright. Does this sound right? Also should I build in place like Bernard recommends? Does that include doing the trailing edge and aileron spars before making the cuts? And...on the non-aileron ribs should I gusset the bottom of the last upright in front and behind the upright? That's about clear as mud. I included a couple of pictures which might help. Thanks! Jack Textor Des Moines ________________________________________________________________________________

Thanks for the instructions! A great help, and once you have done it what a conversation piece... yea it's a 1929 airplane with a hand carved walnut and birch Kevlar reinforced propeller. Bullet proof prop. :) One more questions Chuck, did you carve out the wood for the leading edge and fill in with the Kevlar or just lay it over the le blade as is?

I've carved mine and been flying it with just varnish till I'm sure I like what I've got. Now that I do, I'm ready to protect the le and rebalance. >> Steve and all, This is another one of my typically long posts, so fair warning !! Kevlar is the most abrasion resistant of the composite materials...that's why bullet proof vests are made from it. Using Kevlar for the leading edge was my idea. I purchased the unidirectional Kevlar from AS&S. It comes 12" wide, buy it by the foot, but you need a 4 foot piece. It has all single flat strands of Kevlar, held together with little fiberglass strands every couple of inches. It is some tough stuff, that will quickly dull a pair of good scissors if you cut a lot of it. After all the carving is done, and the prop is balanced, the wood must be cleaned thoroughly to remove all dust and skin oil, with alcohol, and allow an extended period of time for all the alcohol to evaporate. Don't touch the wood with bare hands after that. Measure the length on the blade you need to cover the outer 2/3 length of the blades leading edge, and up half way around the rounded tip. The length of Kevlar must be identical for both blades, for balance reasons. Wearing surgical gloves, lay out a 3/4" width of Kevlar for each blade, on a clean flat surface, and cut to length. It's kind of difficult to get the Kevlar to stay where you put it, because it always wants to curl up, and go crooked. I use scotch tape about ever couple of inches to make it obey. Leaving the tape on the Kevlar strands helps control the fibers, as well as allowing you to stow the piece of material while you apply the Polyester Resin to the area on the leading edge of the blade. Kevlar does not readily soak up the resin, so you have to use plenty of resin, and kind of work it in after the Kevlar is applied to the resin. The scotch tape now holds the Kevlar fibers stay where you put them, as long as there is no resin where the tape sticks to the wood. Patience is order of the day, here. You can only do one blade at a time, with the prop secure and the leading edge you are working on pointing up. Mask off each face of the prop, leaving at least 1/2" of wood showing wider than the 3/4" wide Kevlar, to catch the inevitable runs in the resin. Have everything ready, and a plan in your head, because when you add those drops in the polyester resin and mix it up, you have but minutes to get the Kevlar on and in place. I never use quite the full amount of hardener, to give me a few extra precious minutes. If you don't get the 3/4" wide piece on straight the first time, just wait till after it kicks, then pull the piece of Kevlar back off and discard it, and start over. You'll have plenty of Kevlar material for several re - do's. Now you have the Kevlar on both blades, remove the scotch tape, sand and feather the edge of the resin down, but don't get into the strands of Kevlar. Don't use too coarse of sand paper, or scratches will show in the final product. Make sure the prop is clean, and the work area is clean, and lay the prop down on the flange surface on top of a block, to space it up off the
