Is a slight bending of the straight axle inherently bad? I can't remember which thickness I used, but after all the welding I had it magnafluxed. And then last year I did some additional welding of those bungee "dams" that I added. After that I noticed the wheels are canted a bit inward, caused by the warping from the heat. This did not seem to affect performance at all with all those rides I gave at Brodhead last year. Any thoughts?Dan HelsperPuryear, TN-----Original Message-----

I wish you had asked this question yesterday. I changed my bungeesyesterday as part of my annual Condition Inspection and could have easilymeasured the guide pins and guide tubes. Not so easy with the bungees inplace.As I recall, I made the guide tubes out of .045" wall tubing, welded to.090" sheet V-fitting. There is substantial slop between the tubes and theguide pins to allow for axle motion. It works well enough and I've neverhad the axle bind in the guide tubes.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

I was noticing on my wood gear plan from Don Pietenpol and 1932 FGM that the axel is 12 guage wich is .109 wall so .120 is already larger. On my plan from Don he included a stickum note saying "Don't use this" I guess he was not a fan of the wood gear. I spent the morning trying to find out if I could straighten out my old Axel so I could use my old brake setup etc. but it looks like it is not at all practicle so I will put my order in for the new axel. My Vee fittings are the 16 guage per the plan which is kind of (1/16") thin. I plan to use the vertical Pin setup like so many are now using and I first saw on Mike Cuys ship. Thanks for the feedback on the pins etc. I was thinking that the receiver tube welded to the V fitting would only be as strong as the thickness of that fitting so I hope that the setup will work for me. I like the looks of the system. still deciding on the brakes allthough my wheels are setup for the 4.5" drums which seemed to work ok. I keep trying to remember what my train of thought was back 20 years ago when I started my first Air Camper because I seem to have so much more to think about with many details I dont think I considered back in the past. I just followed the plan and 2 yrs later I was completed and ended up with a nice Piet. I hope this one turns out even better. Craig > Subject: Pietenpol-List: Re: axle bending

Something to consider is that it would trap moisture in there (as nearly all woodhas some moisture content) promoting corrosion. When I disassembled the gearon the J1 Standard, there was wood inside of the anti rotation mechanism tostiffen it up, and it was pretty corroded. My guess is that the anti rotationmechanism was added in the mid '70's. The axle isn't very open to allow circulation, and it gets doused in water regularly(even dew on the grass in the evening). When I took all the gear fittings (fuse and down by the axle) off of 2RN, therewas evidence of corrosion and it's a pretty new plane, ALWAYS hangared. Even though it might take so long to cause strength problems in the metal, it probablywouldn't take long to compromise the wood itself to where it really isn'tuseful. Now, if it were replaced at every annual or two... If you were to to it, white oak is probably the best to use considering its strengthand rot resistance. Just food for thought.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

First off, the axle as shown in the plans should be sufficient. But the key is"as shown in the plans"; i.e. no brakes (or, more precisely, no extended axlerequired due to space needed for brakes). If the space required for the brakearrangement you choose is relatively small, just beef up the wall thicknessto 3/16", as has been successfully done by Mike Cuy and others. If your brakesystem needs more space, use the heavier wall and also get the tube heat treated,like Jack Phillips did.Shoving a piece of wood inside the axle doesn't seem to be a wise approach. Aswas mentioned, the wood will retain moisture, and almost certainly result incorrosion. And the wood will add very little in strength. Just because somethingwas an accepted practice many years ago, doesn't mean it is/was a good idea.And finally, I can't see adding a bunch of diagonal tubes being a viable option.It would be a lot of work. It would add minimal strength. All the additionalwelding will likely warp the axle. Douwe, if you feel the need to stiffenyour existing axle, you may be able to simply weld a steel bar onto the top andbottom surfaces of your current axle. Since your axle is already hidden insidea fairing, the added bars likely would not even be visible. Of course, carewould need to be taken in your welding procedure to ensure that distortionis minimized.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: axle bending

Here is a pic of my planes front view. The axle is 1.5 inches by 0.125 wall andis original to the plane. It does not have anything extra in the center of it.At times I do have a little bow in the axle when loaded to gross weight. I do not have any brakes which means that the axle is full floating and can rotateshould a wheel run low on grease. Ask me how I know. It is hard on thebungee cords when that happens. My feeling is to just use the heavier wall tubeand don't worry about it. When it does bend or flex a little it add some camberto the wheels.
