Jerry,  You are the man, You have not had this glass that long, I know
because I cut the blank.
  You have been a busy beaver ("glass beaver that is") You must document
your time on this mirror.
      I am almost as elated as you are for your sucess in such a short time
for such a thin mirror.
             Please tell all of your support during grinding,... support
during polishing,.. and descriptions
     of your lap (and what size)... You see I have a twin blank and would
love to follow the leader...

      PS   Like a proud papa on the day of birth,  the atm web needs more
information!!!!!
