I am trying to finish up some unfinished business with my Clausing
6913 lathe. This is my question #2. I have a three jaw chuck on it,
and while the outside of the chuck is relatively true (as seen with a

regrind or re-cut the jaws, right? And if so, which way is better? Can
I do it with a carbide insert and auto feed?
