Pietenpol-List: tail hinges

Post by matronics »

Original Posted By: Kirk Huizenga
"Richard DeCosta" This may or may not have been a good idea, and either way it's too late, butI'd love to hear what you guys think of my little tail hinge trick.Referring to this image:http://aircamper.org/tail.gifI cut the tail main beam, the "T" edges, the length of the hinge, theninserted two 5-ply pieces of plywood on either side, replacing the cut outpart, and then some, & T-88'ed in place. Then, I screwed the hinge in, asopposed to carving (chopping, sanding, chiseling?) out where the hinge goes.Keeping in mind it's too late to go back now :) is it good, bad, ugly? Imalso wondering if the corner pieces (not glues in yet) are really neededhere.Richard________________________________________________________________________________Date: Sat, 28 Oct 2000 20:43:38 -0500

I made mine as follows: the hubs are made from 1 3/4 ID .090 wall 4130 tubing 6 inches long, then used 2 giant washers as flanges welded on inset 1/4" each end, drilled the spoke holes from a homemade drill template, had them laced (.160" dia spokes)up with a cross three pattern (one spoke crosses three) onto 18" aluminum alloy rims from our local motorcycle salvage shop (these rims have 36 holes, some have 40), then installed a 3.00 by 18 street tire and tube, finally installed commercial, flanged bronze oilite bushings (two per wheel). These wheels cost $100 each total. I have 80 hours on the ship now and they are holding up very well. The aircraft is an 1933 version improved aircamper (split gear). I think 21 wheels work best for 1932 straight gear aircraft. I have lots of photos of these wheels. Maybe this will help. ________________________________________________________________________________

Hi Henry,I understand the Vi Kapler still sells the cast aluminum hunges. I intended tobuy a set when I was at Brodhead this summer, but while there I talked with agentleman about the hinges and he cautioned against using aluminum. He saidhe had used them on his plane and they continually streaked his tail with blackstain from corrosion. I guess the steel clevis pin and the aluminum hinge don'tget along too well when they get wet (galvanic corrosion). On his recommendationI used AN42 eyebolts instead, and they seem to work fine. One thingI should mention with the AN42's - they need to be pinned after installation sothey don't twist and cause a control surface jam in flight. I think Tony Bingelismentioned this in one of his books.Good Luck, Jack Phillips Pietenpol Air Camper NX899JP Wings finished, Tail finished, Fuselage coming out of the jig this weekend> -----Original Message-----

Hi Mort,The Continental A-65 is an air-cooled four cylinder opposed aircraft engine of171 cubic inches, putting out 65 horsepower, and weighing about 170 lbs. It wasdesigned in 1936 (so it is not much newer than the Ford Model A, but is muchmore reliable). It was standard equipment on many planes built in the late30's and all through the 40's, including J-3 Cubs, Aeronca Champs, Taylorcrafts,Luscombes, etc. They built thousands (maybe millions) of them during the war,and you can still pick them up for reasonable prices. I paid $1500 for theone I'm putting in my Pietenpol, and could fly it as is, but I'm going to goahead and totally rebuild it.It was really a pretty advanced engine for 1936. It has self adjusting "zero lash"hydraulic valve lifters, and is laid out pretty much the same as all modernaero engines. I don't know if that says it was ahead of its time, or thatthere has been little advancement in aircraft engines since the 1930's (probablythe latter).It's a good engine for the Pietenpol since it puts out nearly 50% more power thanthe Ford and weighs about 70 lbs. less.> -----Original Message-----

Jon asked->I guess you cast the hinge pieces...what kind of setup do you use>as far as type of foundry, do you use sand or some other type mold, etc?Rather than continue this in the 'slow Piet list' thread, I put this into a newsubject line. Jon, I'm supposed to be making and selling sets of tail hingesbut I now have a waiting list of over a dozen builders, most of whom have probablygiven up on me and gone a different route with their hinges, but 2015 hasoverwhelmed me with work and I figure the good times can't last forever, I'mturning 65 in July, and I'd better work while the work is available. So, I'vehad no summers off, no vacations, very little weekend or holiday time, justwork. Not complaining, but it's keeping me from building, flying, and makingtail hinges. As soon as I get a free weekend I'll dig out the mess and try toturn out a few sets of hinges and start working on the backlog.To answer your question, the rough castings are sand cast by a foundry here in the good ol' US of A, the same supplier that Vi Kapler used to make the same hinges that I am supposed to be making and selling. Vi sold me his simple tools and jigs shortly before he died, so I make them the same way he did. The parts are pretty simple and durable, and I load-tested the latest batch of castings to prove to myself that they were as good as the ones that Vi had been selling. Here's a little webpage showing the test methodology and results: http://www.flysquirrel.net/loadtest.html . The test bench and work area in the pictures on that webpage are presently under a tangle of twisted tubing, ripped canopy material, snow, dirt, and who knows what else.

Update on the Vi Kapler style tail hinges. I have Bill Budgell's set just aboutready to send out, with John Hofmann's and Clay Hammond's sets roughed out onthe bench to go next. I had to overhaul a few of my shop tools to get themback in shape to make parts, but I should be able to start cranking them out again.It was a cold, windy, and off/on rainy day today but I had no other "honeydo" tasks and my outdoor canopy is snug again so I got a set done. Only tookabout 4 hours, but I spent at least an hour cleaning up tools and settingup to work. The next set will go quicker. And if I had a shop partner, theywould go MUCH quicker, but that's just another excuse.I really apologize for the long delay, no excuse except "life got in the way".I will advise purchasers when I'm about to mail out their hinges.Thank you.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

In situations like this where I have two choice from two vendors for the same productat different prices, here is what I like to do.Instead of asking people with no real skin in the game, I would pose that samequestion to the two vendors. Let them explain why they are the better choice thengo with your gut as to which one has the better reason. You should let themsell themselves, not just take the opinions of unknown people on a forum.Just my $.02.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Pietenpol Plans

Jim;As you can imagine, something like the Air Camper, which has now spanned a periodof time from tube-type radios to the iPhone and beyond, has followed a verycircuitous history in its development. This is also the case for the plans forbuilding the airplane. One of the best and most concise summaries of how theplans developed into what they are today is contained in the 16-page articlethat Doc Mosher wrote in July of 2015, and which is included in an informationpacket that he offers. What Doc points out, and I quote from his work, "BernardPietenpol never did draw any plans. He simply built terrific airplanes'because I seemed to know how.' Orrin Hoopman simply drew what Bernard had alreadybuilt - a sort of reverse engineering because he was there. Hoopman's planswere never copyright [sic] and were free use available from a small numberof individuals who sold them, often simultaneously."I bought my Piet plans from the Pietenpol family about 15 years ago because I feltlike getting them from the family added to the value of what I would own,and indeed it did mean something to me as compared with buying them on Amazon.com.Besides the plans themselves, I also bought an informational manual fromthe family that includes a number of helpful hints and tips about building andoperating the airplane, and a sort of FAQ which was also helpful in ruling outthings that have been tried or thought about but which have not worked or arenot recommended, and why. At the time when I bought my set of plans, the onlyother Air Camper plans that were available were in the 1932 Flying & GliderManual, which I also own, and which is a treasure in itself but is far harderto build from due to the smaller size of the drawings and the lack of lateradditions and enhancements to the F&GM plans. Get the F&GM, but not to buildfrom. Very affordable, and available from the EAA for a very modest amount. If for nothing else, they serve very well to take with you as reading and studymaterial when you travel, which is much handier than trying to carry rolls ofplans but which is still plenty detailed and readable for you to study, think,and learn from. I also own Chet Peek's book "The Pietenpol Story", but it'snot really a builder's resource.You will get the same drawings from Doc as you will from the family, but you willget different supporting materials. It's your choice but personally, I ownthem all and they all have useful and interesting material in them. Doc is adeep and wide resource, he is available by email and on this list, and he isan ardent supporter of Pietenpols and Pietenpeople.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Pietenpol Plans

Some more food for thought...There are TONS of quick build Piet kits out there, otherwise known as abandonedprojects. Most come with plans. There are also a lot of super quick build kits, otherwise known as damaged or derelictplanes that don't even need plans.Nearly all are in the hands of someone who would rather see them go to a good homerather than scrapped.Worst case, wrong gear, fuse and you are worried about the wing... Build new fuseand new ribs. Still easier than scratch building, you get builders certificateif you want. Best case, restore an airplane, feel good about its airworthiness, and have anairplane you can sell with someone else's name on the AW cert. May or may not be what ya want, but worth considering.
