roy,

The more hp, the better. I would suggest 1 hp as a minimum.
If it were my grinder, I would want a Surface Feet/Minute (SFM) range of about 1000-4500. Go here to help you with your calculations: http://www.carycorporation.com/databk/calculator
For example, a 1750 rpm motor with 8" contact wheel with two 3-groove pulleys (ratio range=1:3 to 3:1) would give you a SFM range of 1221-10995.

I have a Kalamazoo and I use step pulleys with a 1 HP motor @ 3250 rpm's. I should have gone with 1 1/2 HP.

1-1/2 - 2 hp continuous duty enclosed and be sure to check the rotation direction. It may be able to be wired for either direction, check it out to see. Depending on how you mount the motor it could be important.

I've got an old (circa 1946) 5hp motor hooked up to my Coote,10" wheel & 1750 rpm, via a set of 4 - 4" pulleys off the motor shaft, and steps of 3". 4", 5", & 6" off the grinder hub.
I also like those pink link-a belts....makes fitting up easy!

 

I have a Leeson 1hp 90VDC motor on my 10" Coote. With a speed controller for variable speed. The whole shebang for a spanking new motor and the controller off of Ebay ran about $225. Believe me just turning a knob to change the motor speed is the way to go. 1hp is more than enough for me. The only reason I see to have more is if you really lean into your grinds. This you will find looses the control you need for better results. Just my 2cents
