Punching holes

hi there, don't know if this is of interest to anyone, but here's something I've been toying with.



Using 0.1mm (0.2 in vid) peck drilling seems to improve the release and reduces plunge depth.

That's pvc in the vid, but could be adapted for card, leather, gasket, rubber etc.

Coupled with drag knife, opens up a new world of materials

Next I'm going to machine a fitting to go around the punch with a spring and foot to hold down the material on retract.
