Yes, this works fine. *It might be just a little slower than

Current headaches with both of the methods I plan to try first. *My

Oh, well, that's going to be a problem with SS workpieces.

Yeah. Makes me regret pulling the stock spindle on the Taig
sometimes. Still it was only 1/4 HP so it might not have been much
better.
