I am building a billiard ball polisher. All it takes is some type of motor
that will turn a turntable covered with carpet. Google how to build a
billiard ball polisher. I have an old right angle 7" grinder I never use
that would work. Can I safely put a dimmer on this to vary the speed and
slow it down?
I think you'd be better off buying a $20 orbital polisher from HF. [or
a $35 one from Amazon or Walmart]
There is a bit of randomness to its orbit that prevents it just
grooving a ball if a speck of crud gets in your polisher. Plus you
don't need to mess with the speed. [And what kind of welder are you
that you have a grinder you don't *need*.<g> ]
Well, whoa, wait a minute there, pal. You mean a regular induction
motor, like you'd find on a bench grinder, jig saw, that type of
stationary power tool? Sorry, you can't vary its speed with a dimmer.
That only works on "universal"-type motors (electric drills, etc.). You
know, the kind of motor that has brushes, sparks and all that.
