For finish machining you might look into adapting a Demril tool as a
tool post grinder which would make it easy to grind the bore to
finished size.

Some older Dremels fit snugly into a copper pipe cap or reducer that
you can solder to a base.

My new Dremel mount is an upright rectangle of aluminum morticed into
the compound slot and bored in the lathe to fit the nose of the tool.
The tee slot clamp is a lawnmower wheel axle bolt which has a low-
profile hex head. A carriage bolt with a washer pounded onto the
square and cut flat on the sides works for larger tee slots.
