Here's a picture of last year's prototype drive train.
Each axel is a 3/8" bolt riding on two pillow blocks. The pillow blocks have a slot milled in the bottom to keep them in-line with the 80/20, preventing them from twisting. The pillow blocks can slide in the 80/20 to tension the chains.
We used slightly larger aluminum tubes as spacers to position the wheels on the axels. We used this system last year and it worked really well. However, we'll be using canelivered wheels in 2008 and will therefore need to use live-axels.
