Oscar,I was going to attend the event and didn't because of 45 MPH winds in the highdesert where I live. Perhaps next year. What do I get for not going flying?Ended up spending a bunch of money buying the wife a new car. Guys, it's cheaperto go flying then to stay home. Save your money and go flying, :)--------Scott LiefeldFlying N11MS since March 1972Steel TubeC-85-12Wire WheelsBrodhead in 1996Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Jiggin and welding LG and wing attach fittings

I promise I searched the archives before posting this question...Those that built the straight axle LG, I am curious how you went about weldingup the fittings. I assume the steps would be:1. make a jig from of some 1 x 1 square tube steel2. Slide bolts through the outer LG fitting through 1x1 jig.3. position "strut attachments" through outer LG fitting and clamp to bottom sideof 1x1 from the side (open end of 1 x 1 jig). 4. install the inner lg fitting and bolt together with inner5. weld outer and inner fittings where strut attach fitting protrude6. repeat 3 more timesAny pics of your jigging would be great. I Looked on west coast piets but did notsee any.--------Bob 'Early Builder' DewenterDayton OHRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Bob---I hope this helps you out. I built jigs out of leftover longeron spruce and plywood and built it up exactlylike the plane. Of course the wood jigs are sacrificial. Hope this helps!Mike C.Ohio________________________________________________________________________________Subject: Re: Pietenpol-List: Jiggin and welding LG and wing attach fittings

Bob, I wasn't as shop savvy as Mike when I built mine. I marked the pieces andclamped them together and then removed them from the fuselage. I then weldedthem on my bench. In order to hold the outer bracket at 90 degrees to the bellystrap, I used a magnetic steel holder on the 90 degree end. You can get themat princess auto or your American McMaster Carr. The pieces fit back on my fuselage and the holes all lined up. But maybe I gotlucky. Scott K.

Mine are actually built to plans, but not welded and are completely adequate andappropriately vetted. Build the pieces, stack them and assemble. I'd recommend drilling a one eighthhole on the blind side of every hole in one part only, and in such a way thatevery part has at least one hole. Then install on the fuse temporarily with smallwood screws to hold each part in place. Then using what ever hole that does not have to be used for the temp install, throughdrill in place. Then step drill to final size. Bolt in place, remove somesmall screw now not needed, lather rinse repeat. Every thing will line up perfectly.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

BobI welded up a jig from angle iron that matched the bend in the side plates.Then clamped the fitting into the jig. You will need to grind/cut a windowfor the strut tab to go through.http://westcoastpiet.com/images/Chris%2 ... Sacramento, CAWestcoastPiet.com-----Original Message-----

Just wanted to drop by and share a few words about Corvair College #30 that washeld recently in Mexico, Missouri. This was my third college, and it was wellattended I think there were more than 50 builders on hand in various stagesof work. Some with completed engines, others in the disassembly and inspectionstage. William and Grace (FlyCorvair), Roy Szarafinski (Roys Garage) and MarkPetniunas (Falcon Machine) were all in attendance, which allowed everyone anopportunity to get one-on-one time with these very skilled and knowledgeableindividuals. Lots of work was completed and several engines were run over thethree day course, to include my own! A few words about these colleges as I stated, this was my third. I first attendedCC#22 in Georgetown, Texas, which was hosted by our very own Kevin Purteeand Shelly Tumino. At that point in my project I did not have my engine availableto work on, so I simply showed up with my camera, a note pad and luckily,my coat it suddenly got COLD in Texas. While I may not have turned wrencheson my engine that weekend, the information and confidence I left with were instrumentalin motivating me to the next stage of construction. Equally as importantwere the new friends I met while I asked questions and mingled around theshop. These events are every bit about the camaraderie and building of friendshipsas they are about the technical aspects and learning about this excellentengine. My next college was CC#28 in San Marcos, Texas also hosted by Kevin and Shellyearlier this year. Another great program that helped many of us get a step closerto completion of our project. I was hoping to run my engine at that event,but weather hampered our plans. None the less, several of us made good progress.On to CC#30 in Mexico, MO I had been looking forward to this event ever since Iwas driving north in a blizzard from CC#28. I was eager to breathe life intomy engine, but not so eager that we would be hasty in our efforts. Finally,the day had come and I was prepared. I could go into great detail about these events, but feel that this writing wouldget way too long winded. The key points Id like to express about the Corvairoption, the colleges and about the people involved are simply this anyone cando this, and do it well. I am not a motor head Ive rebuilt a few small enginesgrowing up, but nothing of this significance. In 2009, I remember talkingto William as he instilled confidence in me that I could do this, and that ifI got stuck he would be there to help, which he has been. His #1 concern beingsafety, he insisted that I do things a certain way following the methods thatare clearly lined out and explained in his manual. While WW might rub somethe wrong way, his approach is always one from the point of safety, and in preservingthe reputation of experimental aviation for all concerned. While hestaken a couple of opportunities to make an example of me in front of others,it was always in an effort to teach myself and other builders what not to do,and why. For that, I appreciate his direct approach. The conversion techniquesoutlined in his manual are very detailed and easy to understand, and the productline has evolved into offerings that will allow any builder a very robustpower option. The bottom line is if I can do it, you can too! There are stepsalong the way that require some attention to detail, but nothing more complicatedthan the rest of the project you are currently building or considering.Dont let the fear of the unknown hold you back if you are considering theCorvair as an option, get the manual and get started today!A few words about my engine run in a nutshell, it was flawless. Not only did itfire right up, but it ran very smoothly for ~1 hour on the test stand. Oilpressure and temps looked good, with no leaks! I drained the oil after the runand found it to be clean with no particulates. I couldnt be happier, and withthe latest advancements, I have complete confidence that my engine will provideexcellent performance.Here is a link to one of the test runs https://www.youtube.com/watch?v=TxmRzHaXbsU--------Mark ChouinardAll framed up... working on rigging.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Jiggin and welding LG and wing attach fittings

Bob Even more commentsBased on the procedure you outlined I am guessing your planning on making fittingsas shown on the wood gear plans ( projecting up through the floor unlike Mikes3-piece modification). In rereading your procedure I think your fitting willend up being too narrow. Remember where these fittings attach there is the1x1 spruce lower longeron plus the fuselage side plywood and a plywood doublieron the inside. The width between the inside of the two fittings should bemore like 1 inch. However I relooked at the wood gear plans and it does notseem to show welding the inner fitting to the strut attachment fitting. I onlysee welding between the outer fitting and the strut attachment. You may wantto review the need to weld the inner fitting.Chris--------ChrisSacramento, CAWestCoastPiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Congratulations on running your freshly overhauled engine Mark Chouinard!!! What a great feeling that is knowing you did the overhaul yourselfand know every part of that engine. I'm in the MOH process on a spare A-65 Continental I have in the hangar right now and it is a very satisfying experience.Mike C.Ohio________________________________________________________________________________Subject: Pietenpol-List: Re: Corvair College #30

Thanks Terry. Life is a lot busier than it once was, so I don't get over heremuch to read up on things. Trying to keep busy in the hangar when I can. Haven'tgot as much done in the past year as I would have liked to, but definitelyhave made progress. The engine run was a big deal... now working on the fuelcell and rigging the controls. Anyhow, I'll keep plugging away... it's looking good so far!--------Mark ChouinardAll framed up... working on rigging.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Jiggin and welding LG and wing attach fittings
