You can do the same thing with the lathe, holding the work in the chuck and

I've heard about making a gear this way on a Navy ship while at sea.
Indexing must have been a pain!

Lots of things can be machined this way, though if the load
is heavy it does the handwheel mechanism no good. But what the heck:
for a hobbyist, the lathe will likely outlive him anyway, and refusing
to occasionally do this sort of stuff to preserve his machine just
limits his capabilities or forces him to buy more expensive machinery
or farm the job out.
I've used the method to clean out the insulation between
commutator segments on generators and series-wound motors. Works OK and
doesn't hurt anything.
