Default Hmmm...

So you wrapped a brass bushing with aluminum tape and put it inside a steel weldment? Isn't the point of the brass bushing to give a greater bearing surface as the control stick base pivot tube rotates around it as depicted in section 39-8?

It would seem that wrapping that bushing with a MUCH softer metal for a steel tube to rotate and bear on would be problematic...

It will probably eventually wear,,,,,,,sometime in my lifetime. Then it just gets sloppy again. The welding process will distort the inside of the tube the bushing fits in. The best solution is for the stick fabricators to ream the inside of the tube back to size after welding fabrication, and for Vans to provide correct diameter bushings for the reamed holes. I have found that most of the Van's fabricated parts receive little clean-up. Now that I have a metal lathe, I would ream the inside of the tube and turn a custom bushing.

Disregard my last post. I just checked today and I also have about 1/8 of play.
