    The problem with that is that I'm not certain what the thread profile
is - probably acme but ... I was just thinking that I can make an
impression of the leadscrew , wax might work or clean the leadscrew well
and apply a release compound and mold one out of JB weld ... and use
that impression to grind a cutter . That piece of plastic is dialed in
on my 4 jaw , and ain't coming out just yet .

  "An old way was to fit a piece of thin sheet metal into the leadscrew grooves. Another was to press sheet lead into the thread or gear teeth."
----------------------
   A lead ball and a c-clamp shall solve the question of thread profile . I have angle gauges I can set up in the mill vise to get the proper angle on the cutter using my end mill sharpening grinding disk .
