So I'm thinking one ball at a time, but reasonably rapid fire, similar to 2006.

Man, we have a lathe and everything... our students took alot of time to build a roller setup out of 80/20 scraps and a 2008 KOP wheel. The lathe idea is a great idea so we can figure out what rpms to set the spindle motor to!

Our design isn't simply a wheel though, it will be a roller that's 4" wide (or a 1-2" diameter wheel that's 4" wide, however you look at it). I'm also toying with the concept of making it a sort of conveyor design so that the moonrock has more acceleration time. Thoughts?
