Thorp Air Command - T18.net

I have been going thru tires in about 80 hours. Checked the camber = -87.7 deg. I removed the tire and the axle. The gear strut flange angle was about the same. Thinking a shim would work, I made a 2 deg shim. Tried to install the shim, the shim angle was so large the axle holes and the holes in the strut flange were offset. see attachment.

Any ideas would be greatly appreciated

Thanks

Have you tried just a washer?

Have you check toe alignment? Camber won’t have a big effect on tire wear. Toe in or out will eat them up pretty quick if excessive and make ground handling much more darty/twitchy.

Per prior discussion of wheel alignment in this forum, I used a slice of a Coke can as a shim. Worked like a charm, although for me it was a toe-out issue that needed fixin'.

Thanks for your inputs. I measured the camber = -2 deg. This tire has 80 hrs (see pic).The A/C has no adverse characteristics during T/O, landing rollout or taxi. I am not comfortable with the bending loads on the bolts (see pic). My approach is, mill a 2 deg taper into a new axle hub face. offset the axle stub holes .025" and spotface (2 deg) the outer bolt hole surface of the axle stub face. My experience in A/C structural testing may promote my overkill outlook. Will advise on the results. I appreciate your inputs

Wow! That’s a LOT of wear. Are you certain the gear are not bent?

Did you check the toe yet? Almost guarantee that’s tow out wear, not camber. Would suck for you to spend all that time on camber and wind up in the same boat! I had a Sonerai with somewhat weak spring gear. The camber was always negative. Didn’t affect wear much at all. Off camber doesn’t wear tires much.....toe does!
