I bought this D.P. in January from a flipper who got it at the auction of a machine shop that went out of business. The flipper put it on ebay, but claimed to know nothing about it. I asked several times what voltage the motors were, but he didn't know how to find out. His pictures were poor, but it had 3-phase wiring boxes mounted to the legs. He'd listed it at $350. I asked 3 or 4 questions about it, then decided not to get it. But he offered it to me at $285 and I bit.
Turned out the machine shop had put 1140 RPM 1-phase motors on it! RPM's are 160 to 3,000. 6 speeds, 6 inch depth of travel. 15-665 Rockwell heads.
When I was looking for a DP to replace my old one, I wanted 3 feed handles, I wanted RPM's low enough to drill in mild steel up to 3/4", and if possible I wanted a 2-gang DP on a cast iron table.
One of the chucks is a Rohm Spiro (West Germany) the other is Jacobs.
Table is 50 inches X 22 inches. It was originally a 4-gang DP, but two heads got be-headed at some point. There are holes of shame through the table. The machine shop ran coolant when they used this and I'm still trying to clean out all the gunk.
I'm making a run of 15 casement window strike plates out of 1/8th inch brass. I used a 1/4" carbide burr and ran it at 3,000 rpm to mill the slot, but I found it was easier and faster to do it by hand with an angle grinder & cutoff wheel.
I made the feed handles out of grade 5 bolts, with knobs from McMaster Carr. It came with the most pathetic excuses for feed handles I've ever seen... 4" handles with no knobs, nor provisions for knobs.
Damm, here's the OSHA guy sniffing around to see if I'm wearing steel-toed boots. Luckily he'll take bribes of tuna not to write me up. Lots of clean-up work still to be done.
