I went ahead and grabbed the Clausing 15" drill press. It's an olive green16VT-1 series one with the variable speed belt contraption, and goes from 500 to 4000 RPM as it's the fast version. Serial numbers and styling indicate it's from between 1962 and 1965. The motor appears to be original, 3/4hp 3 phase and works fine. One grease gun style oil fill port is missing, can easily replace that though. Everything spins up, and there's no horrible sounds, although it does sound like a big fast machine at the highest speed setting. It came with a fixer-upper Albrecht 130 chuck from some other machine.
Somebody went to town trying to remove the arbor from this chuck, complete with a vise, what might be an angle grinder or file and other prying tools. The jaws and shell seem OK. I tried to pound out the arbor with no luck. I finally drilled into it with a 1/8 drill bit, then 5/16ths then3/8ths by hand to try to push it out with a punch. Somehow that got stuck in the hole and I had to cut the arbor off to get the punch out. I'll try to thread the hole and pop the stub of the arbor out with a bolt and stack of washers. The arbor is a super old looking and real Morse, that doesn't appear to be hardened at all, anywhere, considering I was able to hand drill into it as well as cut it off with a hacksaw. Was this normal back in the day?
As for the bent spindle, the last owner did something and it appears to run true at this point. It's a done deal now, so we'll see if there are any surprises when I take the quill out to look at the spindle itself.
This it is my first "large" machine that weighs more than I do.
