Just sat there getting dirtier and dirtier. Now he had to sell it, so we washed it of the brown dust, and he wanted to taxi it to a hose to rinse it. The battery was dead, and wouldn't take a charge. He got in and primed it, and on the 6th flip of the prop, it was running, even on the old gas. Man, that metal prop was sharp, had to put on gloves.

I am using the long fuselage plans. 1) Whether short of long fuselage, axle should be 2" forward of plans location if adding brakes and tail wheel. The short fuselage plans show the axle 17" behind the firewall, the long fuselage plans have the firewall 2" further forward so the standard axle location would be 19" back from the firewall. SO with brakes and tail wheel the axle should be: 15" aft of firewall for short fuse 17" aft of firewall for long fuse Correct? Also since many people increase the front fuse length probably a better measurement point would be the center of the front ash cross member. In that case the axle position would be: 5" aft of the center of the front ash cross member for any fuselage. 2) When I get done with the gear the fuselage should sit on the ground with about a 13 degree deck angle (measured on the top longeron), from the archive info. So if I install the tailwheel and prop up the front of the fuse to a 13 degree angle, place the wheel/tire that I am going to use on the floor under the fuse at the correct 2" forward location THAT is the axle position that I need to build my gear to correct? I can build a Bill Rewey-style jig to hold the axles in that position. Thanks -- Rick Holland ________________________________ Message 4 _____________________________________ Time: 06:56:53 AM PST US From: Rick Holland Subject: Pietenpol-List: Mock fuselage usage Discovered another use for my Bingelis mock fuselage. Come landing gear build time you just turn it upside down and you have the base for a jig that matches the bottom of your real fuselage that you can tack weld your landing gear parts to. You burn it a little while welding to it? No problem just have a bucket of water nearby. -- Rick Holland ________________________________ Message 5 _____________________________________ Time: 07:14:53 AM PST US From: Mark Subject: Re: Pietenpol-List: Continentals are amazing SpamAssassin (score=-2.563, required 3, autolearn=not spam, AWL 0.04, BAYES_00 -2.60) --> Pietenpol-List message posted by: Mark Butch Pennewell wrote: > I had a friend who bought a Cessna 140 which had sat outside for a few > years.

The corsion that can form on the inside of the cyclinders can actually help hold compression in, but when put in use more often than not it gives way. Running an engine way past TBO is asking for trouble. A hundred hours or so is one thing, but if there is a problem you could easily be penny wise and very pound foolish. A problem with the internals can easily damage the cam or crankshaft. Last time I checked a just the crankshaft was over 8 grand (not including the rest of the rebuild and finding one might not be as easy as picking up a phone) and most overhall shops require the crank to be serviceable before you even have an engine core. Risking doubling the cost of an overhall for a few hundred hours isn't worth it. Would you feel like you got your monies worth if you had an overhall that only made it 500 hours? That is essentially what you are doing by running it way over. ________________________________ Message 6 _____________________________________ Time: 07:51:02 AM PST US From: "Keri-Ann Price" Subject: Pietenpol-List: Supplemental Plan Packages for Pietenpol AirCamper Supplemental Plan Packages for Pietenpol AirCamper http://www.geocities.com/keriannprice/Pietenpol_Plan_Packages.html ________________________________ Message 7 _____________________________________ Time: 08:15:58 AM PST US From: "Oscar Zuniga" Subject: Pietenpol-List: Format change --> Pietenpol-List message posted by: "Oscar Zuniga" To subscribe to the digest format of this list, go to http://www.matronics.com/subscribe and submit your request.

Which are you using? the fuselage that appears in the Flying and Glider Manual. The drawings show a wood gear. the fuselage that is on the plans that DP sells. The drawings show the split steel landing gear. the fuselage that was used for the corvair piets. No gear is shown for this fuselage but it is the one most build as it is 7 inches longer or so than the early fuselages.

A-65 runup & flight From: "Phillips, Jack" Chuck, In running some tests with a GPS this weekend it appears my Piet is not as slow as I thought. There was no wond aloft and I was consistently getting groundspeeds of 66 to 68 knots, regardless of flight direction. Maybe my cheap Chinese import Airspeed indicators are calibrated in knots, even though the dial says MPH, 'cause they both indicate 65. So in reality I'm getting an airspeed of 66 knots, or about 75 mph. That is cruising at 2150 RPM indicated. A buddy has an electronic tach - I need to borrow it and verify that my tach is accurate.

My cruise is about 65 to 70 mph, verified with another airplane's ASI. Jack, I'm guestimating the 85 mph for my Full Power Level Flight run. My tach reads low, and my ASI reads low. It will be interesting to compare our cruise speeds. I think there is a radio frequency that we are allowed to use, for air to air conservasion. For cruise, I pull power back to 1850 rpm, and that puts me somewhere around 65 mph. Sometimes I like to put put put around, close to minimum controlable airspeed. I can pull power back to 1650, and maintain about 45 mph. Saves gas, and do some sight seeing !!

A-65 runup & flight --> Pietenpol-List message posted by: Steve Ruse Wow, that is a really smart idea, and it couldn't be any simpler. Never ocurred to me. Should be really accurate too. One thing to be careful of though, some ballasts will change the frequency of the power to the lamp (I know this is true for some fluorescents, and maybe metal halide or high-pressure sodium lamps). Now it could be that the altered frequency is still a multiple of 60hz though, so this wouldn't matter. Using a good 'ol incandescent lamp (from a 120VAC source) should be very accurate though. A drop lamp secured to a cabane should work great. Now you've got me wanting to try this. Something to do next time I'm at the hangar at night...

The filament glows when the power is off so you don't get the flicker that makes the strobe effect you're looking for.

I live in Northwest Arkansas only about 70 miles from Springdale, AR where Bobby hangered. His father, Jim, is well known for his metal work esp. with the English wheel. He is a master craftsman. Both pilots were among the top flyers in the world. I was never even close to their skill level, but I enjoyed flying with them just the same. They will be sorely missed and the airshow industry will have a great void that will take some time to fill. I was also sorry to hear about Tom Poberezney's accident and wish him well. I met Tom around 1993. It was at my very first "official" airshow to fly as a performer. He was flying with the Eagles then and, since I was still practicing medicine at the time, I treated him for a minor upper respiratory infection so he could get through the performance. He and all three of the Eagles were very friendly and gave me much encouragement in my acro work. I still have a large, signed photo of the Eagles sent to me for treating Tom during the airshow. I wish him a speedy recovery. Doc H. Do Not Archive --- Christian Bobka wrote: > Chapter 25, > I got a couple of phone calls from my friend > Lesley, daughter of Tom Poberezney.
