Thanks for all the responses. Other than the Multi-Tool, is there anything I can hook up to a 8", 3/4 HP bench grinder? I have another 1/2 HP motor around here too, and just don't want to buy a motor if what I have will suffice for occasional use. Except for the Multi-Tool, no weld DIY, or more $$ than I can invest in it, everything I've found online has an integral motor. $200 is probably gonna be my limit for now. Thanks for all the advice.
