Default Not Model A

Is there a way to reduce the speed of aa 3600 rpm bench grinder to 1850?

It depends on how it's configured. What brand/ model is your grinder?

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.

or you find one old enough thats belt driven then play with belt and pulley sizes.

What do you need to reduce it for?

Thanks everyone. I do some woodturning and have use a 1"x30" belt sander to sharpen the tools. It's hard to keep the proper bevel. I've s

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.

If you are near a metal recycling yard, it's amazing how many good electric motors get thrown out.

I actually have one somewhere. The ones I thought were pretty interesting were the hand crank grinders for sickle bars with about 4 sets of step up gears.

I have a seated grinder but the wheel is really out of round and the frame needs a lot of work.
