Radio Daze has this set, or individual punches for $19. I have seen no-name sets on Ebay, but didn't find one in a quick search.
Thanks, but what I'm looking for is much more specific. (I already have a selection of Greenlee punches for the basic round holes.)
--The chassis punch for Octal/Magnal (8- or 11-pin) is actually keyed (there is a little protruding "lip" in the edge of the hole) to prevent the male connector from rotating. I am told that this punch exists, but have had no luck finding it, so far. The alternative is to use a keyed metal flange and a "springy washer" to hold the plug to the chassis, and this works fine.
--The IEC punch is a different story altogether. This is an irregular shape: a six-sided hole with rounded corners and shouldered top edges. I am told by people who have made this hole using drills, nibblers and files that it is quite difficult to do -- one person told me it was a good occasion for inventing new four-letter words. Supposedly there is a Greenlee-type punch for it, but no one seems to know where to find it, plus it costs something like $200, maybe. Greenlee, on its website, does not explicitly offer such a punch although it does have a whole selection of rectangular punches. (IEC is the name given to the almost universal A/C socket that is found on the back of most electronic equipment nowadays.)
