Mike,I just got a private response from a member of the list (who I will not namesince he responded privately) who said he used 1.5 x .065 for his axle. Hehas been flying it for some time too.Seems like anything will work. I wonder if anyone knows of any Piets thathad bending problems with a straight axle. If so, what size? We could thencome up with a minimum size limit.Ted----- Original Message -----

Thanks John.This brings up a question. If motorcycle type wheels are going to be usedon a straight axle what is the need for threading a nut. Wouldn't a simpleflange drilled and bolted through the axle be enough?Ted----- Original Message -----

Ted,The Flying and Glider shows a flange/collar welded up with 12 gage, and 1/4inch bolt.This is for both the Air-Camper and Sky Scout, one with a straight axle andthe other with split axle. The plans call-out for 4 of the collars for thestraight axle.Seems like you could use different thickness washers as shims to get thecorrect tightness.Skip>This brings up a question.

Shims will not work if you are using tapered bearings. Tapered bearingsmust be drawn up tight against the race. The F&G Manual shows wheels withbushings. Some older aircraft wheels have straight bearings, but mostmodern wheels have tapered bearings. I don't know what motorcycle wheelshave, or whether it differs from one to another.GeneOriginal Message:-----------------

Good point, it would make a difference if they had tapered bearings insteadof bushings. This thing gets more complicated with each turn.Thanks for the great answers.Ted----- Original Message -----

Ted, I have access to a large lathe and used it to thread my axles and makeflanged nuts for them. The hubs are bushed with bronze and the inner side ofthe hub runs against a large washer next to the brake backing plate. Thewheel end play is controlled by the threaded nut pinned at what I think isthe right adjustment about 0.010" I haven't provided for grease seals as Ifigure the wheel speed is slow, 21" rims, and it is so easy to remove thewheel. I may change my mind in the future but for now simple is best.BHP had a simpler idea he just pinned the flanged washer.John-----Original Message-----
