    I'll have to check into the warranty and see if I'm still in the period.

    Were you by any chance running it on a long/light gauge extension cord? That could cause overheating.

    25ft 12 gauge. That should be plenty shouldn't it?

    If it is OOW then the Woodcraft will searve your needs. I have one and really like it.

    Not sure if this had anything to do with it, but...

    When it smoked, I had a wire wheel on one side and a buffing wheel on the other and was using it at the lowest speed (in fact I rarely use it higher than that).

    Was this inappropriate? Is the grinder supposed to have at least one grinding wheel on at all times to help dampen vibrations or for a flywheel effect?

    You didn't kill it by running it without a heavy wheel. The symptom says electrical problem. Besides the centrifugal switch, the parts list for this machine shows a circuit board that could have failed.

    If it's cooked, you have nothing to lose by opening it up. I think you'll find a set of windings is burned out.

    ...unless you intend to return it under warranty. In that case, don't open it up - that often voids any warranty.

    The motor no longer turns freely by hand or when I turn it on.

    Could unbalanced wheels cause this?
