Dave,I used bronze bushings, got them 1 1/4 ID and 1 1/2 OD, just had to cut tolength.If you are talking about turned aluminum hubs, I assume 7075, $275.00 soundsabout right, based on how long it took me to make mine.Another option is welded 4130 tube with 3 flanges (if you want breaks, 2 ifyou don't) welded on and 2 of them drilled for the spokes. Should be a wholelot cheaper than aluminum.Skip Can anyone who has used the spoked wheel option tell me what kind ofbushings they used? Thanks....Dave in MissouriMessageDave,I usedbronze bushings, got them 1 1/4 ID and 1 1/2 OD, just had to cut to length.If youare talking about turned aluminum hubs, I assume 7075, $275.00 sounds about right, based on how long it took me to make mine.Another option is welded 4130 tube with 3 flanges (if you want breaks, 2if you don't)welded on and 2 of them drilled for the spokes.Shouldbe a whole lot cheaper than aluminum.Skip Can anyone who has used the spoked wheel option tell me what kind of bushings they used?

Dear List, Can anyone who has used the spoked wheel option tell me what kind of bushingsthey used? I've been looking at the photos of Michael Cuy's aircraft and othersthat I took at Brodhead and it doesn't appear that the hubs are fat enoughto have used regular sealed bearings over the 1 1/2" axle. I've found a machinist who will make those six inch hubs but he wants $275.00/wheel.That seems pretty high to me. Is it really, absolutely necessaryto have those wide hubs? I've found some nice wheels that seem really strongand it seems like a shame to take them apart. They even have holes where I canjust bolt on a disk for the brake. But I'll do what I have to do. Thanks....Dave in Missouri________________________________________________________________________________

Hi Dave,I agree with John - all it takes is one really bad landing and if a wheelfolds you might tear up the whole airplane (much less hurting yourself). Ihad a machine shop turn my 6" wide hubs for me - cost me $400 for the pairwith me supplying the aluminum. I just got them back from Buchanan's alllaced up with brand new stainless steel spokes - they sort of make me forgethow much they cost me. I wish now I had polished the aluminum hubs before Isent them off.Mine are designed for a 1-1/2" axle, and I used some Timken roller bearingssalvaged from a set of Goodyear aircraft wheels.BTW, the source I used for my aluminum was a company called Yarde Metals.They have a "Drop Zone" where they sell remnants and cutoffs from jobs. Igot a billet of 6061 T651 aluminum 10" in diameter and 17" long for about$150. Their website is: http://www.yarde.com/cgi-bin/dropzone.plJack Phillips-----Original Message-----Dave, I have heard too many stories about stock motorcycle wheels and hubscollapsing when subjected to a heavy side load. Remember, on a motorcycle,there is no side loading except with a side car.To be on the safe side, and from experience, I wouldn't take the chancethat each landing will be without some side loading. Some of my landingshave been pretty bad. In fact, not many have been without landing slightlycrosswise. In addition, some landings have been in pretty rough territoryand the wheels have taken quite a beating. Each time I think that if I hadnot made the 6" hubs and a wheel collapsed, the plane could have been toast. I think it's too much to risk on the assumption that all of your landingswill be perfect and on perfect terrain..

Subject: Re: Pietenpol-List: BushingsIn response to Dave in Missori: Although there have been many suggestions that motorcycle wheels have no ability to sustain side loads, there are also manyexamples of successful applications of them on Pietenpols. A notable example is Chad Wille (from Washington state I think) who uses a pair of British motorcycle wheels on his Scout. Before Chad used them, his father used the samewheels on his Piet. While it's true that a motorcycle is seldom in a position tosustain a side load, it would be difficult or at least improbable to build a wheel for production which had NO such capability. General statements aside, can anyone out there site chapter and verse on specific failures of motorcyclewheels as used on Pietenpol aircraft? I'd be very interested in the failure mode of the wheels. There are about four possibile failure points and I honestlydo not see where fabricating your own 6" hubs buys much in the way of a guarantee against these failure modes.
