Doug,

I will get a picture but what we did after Buckeye was take off the sprockets and make some delrin (Actually it was my kitchen cutting board, some kind of plastic) rings that were bolted to each side of the sprocket, they had a steep chamfer at the top that pretty much forced the chain to ride back into the teeth on the sprocket. Unless the chain broke there was no way possible for the chain to derail. Worked perfectly for GLR (We Won!) and at Nationals. This proved to be the most reliable and easy solution to using chains yet. Even better than a tensioner.
Very cool. Thank you.

We are working on improving our chain drive before IRI. I will pass the idea to our team.
