OTOH perhaps you could have hit the set screw with a torch .....

Yeah, I shoulda done that from the gitgo, but then given the events that
preceded the grinding fiasco, heat wasn't an option. It will be, tho, on
future occurences of stuck set screws.

make sure you use set screws that are long enough that you can weld on
a nut.
