Go to Post Just take a chance. Dream and live. It's not a wild decision, but just ask yourself - if I got my team just a little bit more spending money, where would my team be then? Then, change that dream into a reality. Help your team sustain itself to inspire more kids. - CalTran [more]

This worked extremely well.
Most of the time the delrin disk at the bottom didn't even do anything and under normal playing conditions there was very little turning friction.
Ditto the use of a needle bearing. As long as the thrust load is handled with something like a delrin ring like Dillon mentioned, the needle bearing is an effective quick and dirty solution.
