A few revisions since my initial post. I've added a second bearing to the vertical shaft and the most noticeable change is that I've made the shell shorter by 2in. The shell is now only 6in tall. I tried making it even shorter but the change in weight was negligible and the grooves for the UHMW were starting to get too close together.

The "belt" in the pictures are just a representation for the chain. The main reason I went with the chain was it was easier to pack it into a smaller package. It is also easier for my team to work with sprocket/chain than with belts/pulleys.
