These little motors work great. They turn very slow and have lots of power. My booth is small and holds 3 butts or shafts in any combo needed. I mounted 3 of these with bearings holding the other side of the cues. They spin the perfect speed to spray back and forth the length of the cue and not stop. Each has it's own on/off switch and they can run overnight with no problem. One has enough power to turn as many pulleys as you want. My first booth had one motor and ran 3 cues on belts and pulleys. When I upgraded my booth it was easier to mount 3 motors then build a chain system.
$20-$30 new. Their main use is oscillating fans and heaters. I bought old fans from the second hand store and took the motors and on/off switch out. $5 each.
