Another common thing I did was to collet hold a part and grind a small point on the out end to set into a female tail center for the next operation. Often that might take 30 seconds per part and give about and less than .0005 run out, and insure stabilizing the out end of the part with the point later snubbed off to desired part length.

This could take less length than putting a normal (concave) center, and with many/most parts hard putting in a normal center was not possible

I would probably tap the end of a piece of round bar M1.6, then red loctite the set screw in. Machine the sticking out bit, then throw it in the oven to break the loctite. I'm not saying that it would work, but that would be my first go.
