Custom bushings

[asid61]

The thing is, the bushing looks pretty strange, and I can't really change the design at this stage (it follows an ultra-space-saving design that requires its weirdness). Basically I changed the design so it can use a smaller bearing, which is like 7/8" inner diameter and 1.125" outer diameter. However, it has a very large flange that's around 2" outer diameter. I'll look into using plastics for machining and cost without sacrificing strength. I've used UHMW in the past, but we tend to have a lot of acetal so I'll try that on aluminum too.
