Re: [CAD_CAM_EDM_DRO] Optical Center Punches

Thanks Joe,

Sounds quite useful. Although I'm now using using CNC to spot holes and
drill them, I still occasionally need to punch scribed lines. that
looks like a good answer to trying to hold a loupe and a punch, and
strike the punch (hopefully). I'll check out the MSC catalog when I get
home. Or I could make up a block to hold my old plotter bombsight.
