The one in it now is a 30 rpm identical to this 200 rpm. The 30 spins a little slow and the 200 needs some type of speed control to slow it down. Fortunately for me, BIGGDAWG already tried everything, so I just used his parts list.

This one looks promising, too.

Something like the 20.95 PWM speed control on this page was recommended so the speed on the case spin can be controlled independent of the blade speed. I have two and have tested them. They work good. Similar ones can be found cheaper. You can set the power at 12v and vary the speed of each motor. I'll install them as soon as I finish the case feeder.
