RE: Converting a hand crank grinder to electric?
i use a 1 1/2" on the motor and a 10" on the grinder. just moved up this year to 1/2 hp up from 1/3,same rpm. mount it on anything you mentioned, I've been tweaking mine for years, different pulleys,etc, just use something easy to clean,easy to disassemble and a on/off switch mounted nearby is a nice thing too.in case you have tokill the power kinda quick.
