Hey guys. I've always just used the bench grinder available but never owned one. One big task I can see in the future is removing epoxy and paint from metal. What size motor and RPM unit am I looking at? I don't want to press into it and stop the motor. It will be wire wheel mostly.

Depending on the size of the part it may be more efficient to use a angle grinder and stripping wheel.

Make vice jaws, though for a quick/dirty solution, you can use your set of hole saws to make the right diameter in a couple pieces of 2x4 or 4x4 wood clamped together, that don't need rigidly mounted to the vice, just to sit between the jaws and work piece.

Do you even need a power tool? How much are we talking about, enough that sandpaper by hand won't work? I mean if it's going to be repeated in the future, then do make some vice jaws.

What is the budget for the bench grinder? You're not really going to bog it down with a wire wheel on tubing, little pressure needed for paint and epoxy removal. Something 8" with 1/2HP in a major brand new, or used, depends on your patience. It's hard to get "too much" grinder so I would be forward thinking about other long term uses.

To answer your original question, a true 3/4hp motor will handle a job like that.

If going new, well, Baldor is still true rated, but imports you may want to lean to a 8"+ hd model.

How tight do you think the vise needs to be just to hold the tubing enough to remove paint/epoxy?

Some critical thinking is missing here.

Out of the box idea...paint stripper (aircraft stripper is some strong stuff) may be a good option. It would certainly cut the dust out of the equation.

I'm not trying to talk you out of a bench grinder...everyone should have one! My small unit is a blessing and would do your job all day long. It will stall if I lean into it, but all homeowner's models will. I like the smaller ones for the safety aspect, but I don't do more than 5 minutes of wire wheeling at a time.
