Well, I've been experimenting with macaroni bearings, and had some pretty
good results. You can attach 24 & 40 tooth gears directly to the 2x2 rounds
- this means the axle only has to take all the load at one small point. I
haven't yet tested this arrangement to failure, but it's pretty strong. I've
been making larger "bearing blocks" which can be integrated fairly easily
into non-SNOT chassis.
I'm using these in my next big project.
