How did you cross-brace the frame?
The frame is cross braced by two welded 2X1 tubes. They're about 6 inches in from either side, but we probably plan on changing that depending upon the game.

Thanks! We thought that would be a nice way to make it simpler all around. According to the CAD, the it weighs about .3 pounds.

Thank you! We used #25 chain, and it seems to work out well. The middle chain runs are a little bit less tensioned than we would like, but we plan on fixing that when we add the bigger wheels. Even though it is a little bit loose it still has never fallen off.
