Hello all hope you can help with a question. If you look at the attachedpicture you will see the bolt holding my gear spring assembly together isresting on the bolt head and nut. Should I use a longer bolt (rather not)so the stress is on the bolt shaft? Or fashion a pin with cotter keys oneach end? If I do that should it be 4130 rod? I tried to cut the head offan AN bolt tonight and they are hard! If I do the pin, should I hardenafter cutting and drilling? Could it be soft steel? So many questions,thanks for your expertise!Jack TextorDSMNX1929T________________________________________________________________________________

Mike, I hope your engine project goes better then mine did. I took the engine apart and did what you did. It took six weeks for them to call and tell me my crank was cracked. Another three weeks to find and buy a second crank. Back down to Texas with it and four weeks later they called and said the need additional repair. Then they sent the wrong bearings. I had to send them back and get the right bearings. What a mess. It took until about a month ago to get it all back together. Just a whole series of bad breaks. It started on the third blade. It sat there and ran, all the trouble was forgotten Dave Nielsensentuchows(at)aol.com-----Original Message-----

Gear QuestionJack, all the drawings I have seen use a longer bolt. Not being a metalurgist I can't help with the pin bit. You're probably going to cover the whole thing up with some sort of cover so why the reluctance with using the longer bolt? That would be so much simpler. C ----- Original Message -----

OK, I may try a stock "A" manifold this spring. I have a log type with the "B"carb and can't get an idle below 700rpm without it quitting.--------PAPA MIKERead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/img_ ... ___Subject: Pietenpol-List: Re: Gear Question

Jack,I would say that the arrangement in your photo is not ideal. I'm not crazy aboutthe idea of that washer acting on the nut and the head of the bolt. Best notto impose bending loads on the bolt. Would be better to use a longer bolt, likeyou say, but what would prevent the bolt from sliding over to one end or theother?. I much prefer the arrangement shown in Mike's photo, with a sleeve,and hole located away from the washer. That way the bolt is only loaded in shear.The two designs (Bingelis and Buckeye) mentioned in this old thread utilize a similar method, with a sleeve. http://forums.matronics.com/viewtopic.p ... 329387Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 27 Feb 2012 17:00:39 -0500

The floor braces are there to handle compression loads from the landing gear.They should line up with the landing gear/ wing strut attach points, HansNX15KVWaller, TX-----Original Message-----

Hans is correct. Make sure the ash cross braces line up with the landing gear/wingstrut location. I had to add another piece for rear mount because the bestlocation is bisected by the rear seat. http://www.westcoastpiet.com/images/Chr ...
