This is my 5th design after this season ended. I like to go back and CAD some designs that worked well. Anyone else do this?
Humm… looks very familiar, http://www.chiefdelphi.com/media/photos/37698. I do like the sheet metal work here though. Also how are you tensioning the belts, just by stretch? Thats how we did it but it can get tricky and I’m thinking there has to be a better solution than that with this setup.
Honestly theres no relation there. It’s actually here http://www.youtube.com/watch?v=sew-HUc0lxY 
I wanted to play with the tread setup for future reference. If I were to have it made it would have a similar tensioning system to 639’s; it’s just cool.
