From: "taildrags" Michael; are you talking about the cooling scoops/eyebrows? You can take a look at this page to see what I've done, or am in progress of doing, on Scout: http://www.flysquirrel.net/piets/engine/eyebrows.html They attach to the engine in two places: at the top or inside, there is a mounting flange that secures to two of the engine case bolts. At the outside, they attach to two of the rocker cover screws. Total of four mounting points per eyebrow. Let me know if you need any other info, but the pictures are informative and as you can see, they are virtually identical to the scoops that are flying on hundreds, if not thousands, of Cubs and their cousins. You can get an idea of the problem areas on these parts by looking at pictures of old scoops, like the ones here: http://www.piperads.com/ads/j3-cub-cooling-scoops/ Anyplace you see stop-drilled cracks or doublers, that's a problem area. The scoops get buffeted by propwash, leading to metal fatigue at the fastener connections. If you figure 2300 RPM for 1000 engine hours, two propeller blades will create an impulse 276 million times over that timespan. What's the fatigue life of aluminum? Ten to the 7th cycles? ;o) -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=409489#409489 ________________________________ Message 13 ____________________________________ Time: 10:47:34 AM PST US Subject: Pietenpol-List: Re: round tube wing struts From: "womenfly2" Just a thought ... you could make plywood ribs, epoxy to round tube, use an aluminum tube trailing edge. then cover with fabric. -------- Read this topic online here: http://forums.matronics.com/viewtopic.php?p=409491#409491 Attachments: http://forums.matronics.com//files/lift_strut_fabric_covered_204.jpg ________________________________ Message 14 ____________________________________ Time: 12:24:42 PM PST US Subject: Pietenpol-List: Pietenpol AirCamper project for sale From: "canaweb" FOR SALE BY BUILDER with Ford B motor & mount, spare block, spruce fuselage, & tail feathers.

Parts have all sat around for a long while. I'll get a few pics of the motor and other parts. I have the model B engine and mount as well as tail feathers and rear lift struts. Chad Willie made me an entire fitting set. I believe I still have most of the instruments, but I can look to see what I still have if you have an interest. http://www.flickr.com/photos/canaweb/sets/72157635369569158/ Sitka was used throughout - obtained from a lumberyard in Stormville that used to cater to the EAA crowd. A wood had proper # or rings /inch, etc.. Glue was aerolite.. one fuselage side was left off but I have it, ready to glue on. I'm sure by now there are better glues available. Ply was marine, if memory serves.. First batch of photos is when I first started the project, last ones are current state. Gear is split type and was once on a Pietenpol owned by Ernest Gann. I found all instruments, and also believe I have some turnbuckles & shackles. Empty block was used for spacing, but the B with all internals would need to be rebuilt.

From: "Bill Church" Ear muffs? Never heard them called that before. Never thought of the engine as having ears. I suppose eyebrows doesn't really make sense either, since the engine has the same number of eyes as it does ears. But cooling eyebrows is usually the terminology used (assuming you're referring to the scoops that are used to direct cooling air over the cylinders, as per the J3 Cub and similar aircraft with exposed cylinders). Referring to them as "ear muffs" will likely elicit a few raised eyebrows (pun intended). Just sayin'.

I had a tailwheel with a leaf spring that stuck out the back about 14 inches. I managed to do a ground loop while taxiing and the long tailwheel had enough leverage that it broke the tailpost when the tailwheel hit the edge of the taxiway. It didn't help that my tailpost had some rot in it. When I removed the fabric to make a 10 in. scarf joint in the longerons, much to my surprise there already were two scarf joints in the longerons! (see photo). The old ones were made horizontal with Resourcinal and looked good, so I made mine vertical (with West System). I bought this Piet as a project and uncovered the wing and tailfeathers, but didn't uncover the fuselage - should have. From some wear evidenced on some fuselage parts, I suspected it might have flown sometime in its life. Now I'm even more convinced of that, as it appears this is not the first tailpost failure for this ship. For those with this type of tailwheel, better keep it going straight (not a bad idea, huh?)

Now I'm even more convinced of that, as it appears this is not the first tailpost failure for this ship. For those with this type of tailwheel, better keep it going straight (not a bad idea, huh?)

When I had a forced landing in my Piet, the ensuing groundloop cracked the right lower longeron. I ended up going away from the leaf spring tailwheel to the BHP A-Arm desgn, and glued a wedge of spruce in between the lower longerons with plywood doublers top and bottom, as shown in the pictures below: Here I've glued the spruce wedge (with lightening holes) in place between the lower longerons. Note that when I removed the plywood doubler along the tailpost, none of the glue joints failed, but the wood tore. This was glued with resorcinol. Here is the finished repair, before covering. The damage done by the twisting of the leaf spring in a groundloop convinced me to go to the A-Arm design. I think that design would tear away before it would cause such damage to the fuselage.

I had a tailwheel with a leaf spring that stuck out the back about 14 inches. I managed to do a ground loop while taxiing and the long tailwheel had enough leverage that it broke the tailpost when the tailwheel hit the edge of the taxiway. It didn't help that my tailpost had some rot in it. When I removed the fabric to make a 10 in. scarf joint in the longerons, much to my surprise there already were two scarf joints in the longerons! (see photo). The old ones were made horizontal with Resourcinal and looked good, so I made mine vertical (with West System).

(could be partly due to a very weak bungee on the right side. by the time I turned at the hangar and shut down the leg was splayed out pretty bad. I had thought I would go to coil springs on them but as the time to fly just has not been that much and I feel pretty comfortable with the Cub gear as it is. I just need to find the lowest price but timely delivery source and get some in and change them.having never done it I am not at all sure what I need.I seem to remember 1080? as a strength rating but that may have been on my old Tri-pacer I used to have.any good recommendations? I looked up Chief aircraft and have ordered from them in the past but figured this would be a good place to ask first. thanks.

I've only recently got back into flying my Piet and I've noticed that the itty bitty Piet tail wheel really odd angle with 600 size tires. I am thinking that adding the Scott 3200 tail wheel will (1) give me better steering control in grass as well as on pavement, and (2) will reduce this the angle of the fuse when on the ground. Looks like a few folks have gone with the Scott 2000 tail wheel (solid rubber). It looks to be a couple inches larger. Has anyone gone to the larger tail wheel? Those of you in the know, do you know of an adverse reason for using the larger tail wheel.

First, weight. Most Piets tend to be tail-heavy, and according to the Aircraft Spruce shipping weights, there is more than a 2 lb difference between the 2000 and the 3200. That's a lot. Second, aircraft angle in the 3-point attitude. The Piet's FC10 airfoil can still be producing lift with 5.00 or 6.00 mains and a big tailwheel. The original configuration is with a tailskid, which put the tail down lower. The people who are flying with spoked wheels and a tailskid probably have the plane nearer to a full-stall in the 3-point attitude than airplanes like mine, and that gives you the slowest landing speed and the shortest landing roll. Lastly, you should try taxiing a Piet with the 6" solid Scott on grass or pavement. It will turn on a dime. Matter of fact, I have thought of changing the spring tension on the tailwheel on mine to reduce the sensitivity just a bit, although I do like to have the ability to make it go precisely where I want it to go. Now I'll wait to hear from those who may be using the larger tailwheel to see if I've missed an even better deal than I have with the solid 6". -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=409532#409532 ________________________________ Message 30 ____________________________________ Time: 09:42:18 PM PST US Subject: Pietenpol-List: Re: Elevator control trim From: "taildrags" Wow. Peter's setup is absolutely gorgeous! Nice work, and professional. Mine, by contrast, is stone-age crude. I have a bungee cord that applies biasing force to the bellcrank on the walking beam. I made it adjustable, but have never adjusted it because it never needed adjusting. Except it's been in place for five years now and the bungee has all but lost its tension, so it's time to replace the bungee. Here are some pix: http://www.flysquirrel.net/piets/trim.html Since Scout has a 16 gallon nose tank, I'll never be able to trim it just right with the stone-age setup that I have. After I gas up, I need to hold a touch of back stick for awhile. As the fuel burns off, it starts to go neutral. With low fuel, I'm holding just a touch of forward stick. With Peter's setup, I could just nudge the trim wheel and I could keep the altimeter needle perfectly on my cruise altitude, but with my Fred Flintstone setup, I have to keep looking at the altimeter and reminding myself to hold back pressure on the stick. No... wait... was that forward pressure? I don't remember... let me look at the fuel indicator (which is a bent wire sticking up out of the fuel filler cap out on the nose!) -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=409533#409533 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
