Re: Not Model A
It depends on how it's configured. What brand/ model is your grinder?

Re: Not Model A
I would just pick up a different motor, as fractional horsepower motors are quite cheap, especially at swap meets and garage sales. I mounted a wire wheel to a 1725 RPM motor, as most of the time I like the slower speed better.

Re: Not Model A
or you find one old enough thats belt driven then play with belt and pulley sizes.
What do you need to reduce it for?

een some homemade jigs for bench grinders and won't have to worry as much about heat with a slower speed. I'll keep my eyes peeled for a slow one. Sewall |

Re: Not Model A
If you are near a metal recycling yard, it's amazing how many good electric motors get thrown out.

Re: Not Model A
I have a seated grinder but the wheel is really out of round and the frame needs a lot of work.
