   John,


            Please let me know, and all on the list of your progress of
figuring a mirror by machine.
   From what I understand this is not  something that has been done with
success. The commercial
"dogs" will want your formula big time if you are successful. Not
to say that you can't do it but I would
like to here other thoughts of the list as far as figuring with a machine.
      Russ J.
