While digging around today, I came across a nasty canvas sack full of rusty Greenlee hole punches..from 1/2" to 4" in diameter. They came out of a machine tool dealer that was closing the doors about a year ago, and Id actually forgotten about them. Used the bead blaster on them, got most of them fairly rust free, will finish the rest of them tommorow.
Then what?
Ive used many Greenlee punches, conduit work mostly..up to about 1 1/4 diameter, using the trusty Bolt and Socket Wrench method..but I figure its gotta be a bitch pulling a 4" punch through the side of a can.
Ive got a hyraulic hand pump..but no clue as to whats needed to somehow put the hand pump and hte punches together. Im doing more industrial electrical now days, so it would be really nice to have the ability to use these.
There was no bolt, nor bearing etc for manual operation..so Im gonna have to come up with the draw bolts, some bearings etc at the very least.
Will a grade 8 bolt be enough to wrench on? How thick can this sort of punch actually cut? Ive got a client who wants me to install muffin fans in a bunch of Moog mills..and the cabinets are fairly thick. Id rather not spew cuttings in all the drives and electronics with a sabre saw...brrrrrrrrrr

"If thy pride is sorely vexed when others disparage your offering, be as lamb's wool is to cold rain and the Gore-tex of Odin's raiment is to gullshit in the gale, for thy angst shall vex them not at all. Yea, they shall scorn thee all the more. Rejoice in sharing what you have to share without expectation of adoration, knowing that sharing your treasure does not diminish your treasure but enriches it."
