I just finished the third and final power drive conversion on my bead roller. First try was a HF 120v hoist motor worked great but no speed control, the second attempt was using a treadmill motor and controller but the speed controller would start at too fast a speed then adjust up and down ant the tq was not the best. This one is great I used a 12vdc wondermotor and 120 to 12v power supply and motor controller.
My bead roller is home made but not by me, a fellow in Fl made it for me. He has videos on you tube under courtjester I think. Here are some pictures.

I also built a foot pedal to control the speed from a crawl to full speed. The foot pedal was also with help from court jester. Thanks tom
