It sounds like it would take many hours, With a decent grinder
already adapted to the toolpost, it only takes 15 minutes or so
to true badly worn jaws, and maybe 5 minutes to do some with light
wear.

Yeah, but how long would it take to clean the grinding dust out of the chuck
and any that may have fallen on the lathe's ways?

Problem one. How do you ge the bar accurately center drilled if your
chuck is shot?


3) Center both ends in the dead centers and turn a section ...


He was turning a diameter in situ. This would
give an accurate diameter, concentric with the spindle
axis, to lap against. I thought this was one of the
nicer features of this approach.

Too bad I tossed out all my clapped out three-jaws,
I would have tried this.
