Any safe way to gear down a grinder?

Don't bet the ranch on my electrical knowledge.  (A)

The only trouble with a speed control is that the power seems to drop more than the speed. If you get the thing down to the speed you want it will dern near stop if you put a load on it. Using the belt reduction, on the other hand, increases the power so the speed will stay nice and constant. I notice this when I was making the arrow lathe that I posted a while ago. If I just used the sewing machine speed pedal I could almost stop it with thread tension. I made an idler shaft with a couple of pulleys and it works great. Nice and slow and it will break the thread if I want.

Hawkdancer:
I'm trying to visualize all this!  So I can put it together!  Thanks!

Rheostat will work but is hard on the motor, pulley change is the way to go if you can work it out.  :)
