Hmm 30 lb. weights spinning at 2400 RPM....sounds adventurous! They are actually 10" pneumatic tires. We've tried a number of different sizes, types, and configurations of wheels, and we've since found that opposing sets of paired wheelchair wheels (4" gap - balls compress 3") are much better. The paired wheels create a channel which really seems to help accuracy. At 2400 RPM, they propel the balls to around 50 mph, so yeah, we'll be cutting back on that *just* a smidge. We were hitting our target dead center every time though.

But just wait until you see our black hole-powered ball collection system and our 200 ball/second feed mechanism. You can't see them in the pic because they are out getting chromed...
