      The cross slide nut was badly worn on one of my lathes. I repairded it with
      some "thread restorer" goop from loctite that I bot in an auto parts store.
      Seems there are several other brands, too. Claim is, the resored nut is
      equal to grade 5 strength. all I know, is the slop is gone, and to follow
      the instructions exactly, or else.
