    A lathe would not really be the ideal tool.There have been many hand held, jig fictures made for this purpose. A lathe would be very slow, and you are dealing with an all brass, copper assembly. That is quite plastic as materials go.

    I just ordered a concentricity gauge from 21st Century. Very clever design, it also uses a test indicator instead of the typical dial indicator. You can buy it without a test indicator if you already have some.
