I have, from an estate sale, a nice new 1/2" keyed drill chuck mounted
to an MT2 live center. The chuck rotates on the center.
What purpose would something like this serve?

This set up is often used to true up small electric motor or
generator cummutators. One end of the shaft is held in the lathe's
chuck, the other by a chuck like the one you've described. The area
where the brushes run can then be resurfaced.

Ah, that makes sense. Holding a small diameter rod between spindle and
tailstock, where the stock is too small for a center.
I guess I'll keep it then.

I wished I had one a number of times. How about holding small diameter
rods?
