Roy,treadmill motors are dc variable speed,which is a good thing,as long as you can get the controls for it.1 1/2-2 hp would work great,you could get by w/1 hp.The downside is,those motors are open which will allow grinding dust to enter motor,which could possibly result in an electrical short out resulting in the loss of,at least your motor.There are knifemakers that use open motors,but they clean them out regularly w/air hose,etc.,TEFC type motors would be a better way to go,(totally enclosed fan cooled).As for changing your name,go to the bottom of this thread and click on contact us,send an email to BFC asking them.
