I think our wheels were about a pound each last year. Then again, we were concerned about machining time, and not weight. It would have taken twice the time on the lathe/bridgeport to take another 1/4lb out of each wheel... Not worth the effort for us, though YMMV. Good luck with the lighter wheel.

Weight is everything. 1.5 pounds down low is 1.5 pounds of speed you can put into your scoring mechanism.

I have the feeling I'll be seeing another sexy and competitive robot out of 114 again this year! See you at SVR

This one is a 2 op on the CNC. The rivet holes are all even mainly just for show. We actually just sort of drill them on with a power drill when installing the tread. It saves a lot of machine time, and cost.
The 5 pattern is far more stylish, and lighter. Besides, everyone else does 6 or 4, which is why I usually stick with 3, 5, or 7.
