Re: "Traditional" shooter help
So we have implemented a direct drive mini-cim, with 4" colson wheels. We have serious vibration as the colson wheels are not balanced. We have inconsistent marginal shooter performance.

I think we have two problems.
1) we don't have enough RPM for 4" wheels (not possible to upsize). I'm toying with upgrading to a belt drive to upsize the rpm and save the mini-cim (below) a

2) the colsons are not the best re stickiness to the ball. As evidence of that we added a say1.5 lb steel flywheel and it made no difference to the ball shooter performance. It must have been slipping. Cleaning the colsons with alcohol helps.

We noticed 5 minutes before bag time that our shooter mini-cim (new this year) has higher friction when hand rotating its shaft but its no-load current draw is not excessive. I'm thinking that means bearings.
