Howdy, I used a Coote for the first 3 or 4 years I made knives. It was used HEAVILY. I had mine set up with a 1 hp motor on a hinged plate, with a 3 step pulley on both the motor and grinder. If you reverse the pulleys you have a "manual" 3 speed grinder. It only takes a few seconds to lift the plat and move the belt to the desired pulley.... really worked good. The main shaft bearing on mine froze up after about 5 years of use, but again it was used very hard.
For the money you can get a pretty darn good grinder with the Coote.
