Bob, I will bet you will find that it takes two layers of brass tubing.
I have done this with zero issues on three jets. My eurofighter was this way, I built a Boomerang XL for a guy and did it on his, and my latest Isobar is temporarily that way till the wheels and brakes I want show up and I don't know when that will be.
You can cut a small circle in the two shimmed brass tubes and run your set screw straight to the axle.
PS, how cool I figured out your delimma
Sean,
You did figure out about 80% of my delimma. The other 20% is that I don't have the smaller axles that fit the wheels and I want to fly this weekend!
I think I'll try it this way and if I see a lot of grey gunk comming off indicating a lot of wear in the aluminum hubs, I'll put the bushings back in and break bad and buy the smaller axles...
Bob
