I won't be attending nationals but I sure would like some more information or pictures on that gearbox. I'm most curious as to whether that is a plastic gear I see mating with the drill motor and the specs on it. If that is indeed plastic, where did it come from and how is it working out for you? Thanks.

The delrin padded chain tensioners are a really good idea. Are they bolted in place or is there some sort of a spring device behind them that allows them to automatically adjust to keep tension?

the delrin is riveted onto a piece of bent lexan, and the spring force of the lexan provides a constant force against the chain

here are some more pics of the gearbox, if you so desire them. the delrin gears have held up fine, they are probably the least worrysome part on the entire robot.
