Ah yes! The million holes! I've just spent part of the weekend starting to make a vacuum printing frame for borderless prints. (All the ones I could find for sale were either too big, too pricey or both!) I've drilled 760 1/16th" holes in a 1/8th" thich aluminium 10" x 12" plate and now have to experiment with the vacuum arrangements. All good fun. Part of my plan is that I will also be able to use the thing for copying old photos, postcards, etc.. Before starting the marathon drilling session, I bought a pack of ten drill bits, thinking I'd probably break a few, but having gone to that trouble of course I didn't break a single one. Probably down to the quality of the drill bit rather than my drilling technique!
Best wishes,
