   I wonder if the stamping operation would adequately flatten blanks cut with   
   a Greenlee punch, guided to not need the center screw. They cut a larger   
   blank with less force than flat-faced punches. The points could be rounded   
   as much as the press allows to reduce distortion.   
      
   One company shop had a bench press that located and clamped the lower die   
   between four horizontal setscrews. The punch fit into a round hole in the   
   ram, the square-sided die had two beveled edges for the setscrews. At first   
   it was difficult for me to align but it was very versatile and could punch   
   the square and D shapes needed in electronics.   
      
   The punch had a slight taper above the parallel section which would hold the   
   die centered while I adjusted the setscrews. If I had to convert an arbor   
   press that might be an easy way to fixture a die that could be hardened and   
   then surface ground. The Lindsay book on making punches and dies suggests   
   making and hardening the punch first, then using it to finish the die before   
   hardening it.
