Clausing drill press followup

I went ahead and grabbed the Clausing 15" drill press. It's an olive green
16VT-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 then
3/8ths 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.
