/diy/ - Do It Yourself

I want to make a rotocasting rig, the type with two square frames nested one inside the other so that it spins the mold on all axes. Image related, someone's ghetto version with a hand crank, though I plan to build mine a lot more robustly.

The frame itself and the gearing for the rotation I can do easily, but some of the plastics/resins I plan to do take a long time to cure so I'd like to motorize it. What would be a good source of a smallish electric motor with decent oomph that I could plug into a standard 120v outlet? I can gear it down if I need to, but the lower the starting RPM the better.
