      stuck chucks is to bind the pulley with a strap wrench and
      apply leverage with a board in the chuck jaws.

      As for regrinding chuck jaws, you put a die grinder, Dremel
      or whatever on the toolpost. Use putty, rubber bands or
      rings to bias the jaws outward against the scroll as if it was
      gripping a part, and then grind the jaws. it makes a great
      improvement in the operation of the lathe.
