Re: Ball Launcher
our team ended up using the same wheels we made when we first prototyped our shooter. They are aluminum with a kurnled face. We had an issue with balls getting chewed up by them being too close, so we spaced them out a bit and used some rubber bands. Problem was we kept loosing rubber bands!
In the final design, the rubber bands were replaced by o-rings in a groove we turned into the wheel. Now our shooter is damage free, but we do leave catwisker black marks on the balls if we use brand new orings.
