Lock Frame Tutorial
    Lock bodies modded and unmodded, all dimensions are in the  
conversion instructions furnished with the kit.
     The lock can be milled without the use of a holding jig like the one
shown here but it's not fun.  I would use a belt sander or Dremmel to
remove most of the metal, the harmonics without the support will trash
your end mill.  The lock is so hard that carbide must be used.
