A strong gentleman who was picking up his own stuff that he won in
that auction, helped me load it into my pickup.

At home, I easily unloaded it myself. It weighed about 350 lbs, but
nicely balanced on the tailgate as I lowered it, first on two pallets,
then I pulled one, then I pulled another. No problem. And I am not
even strong.

The good news is that it seems to work fine. Powers up, spins, and
changes speed. Another good news is that it is NOT obnoxiously
loud. Really quite acceptable for a strong machine.

There is a diagram of speeds next to the speed adjustment handle. The
lowest speed depends on what is the motor RPM. For a 900 RPM motor, it
is 235 RPM, for a 1750 RPM motor, it is 475 RPM or so (going by
memory).

So, since the present motor is a 1750 RPM, this is a 475 RPM lowest
speed drill press. The motor seems to be the usual 56 frame size, so,
finding a replacement motor (say, 1 honest HP 900 RPM motor) should
not be a problem. I am xposting this to a woodworking newsgroup in
hopes that someone who wants a faster drill press, may want to swap my
1725 RPM 3/4HP motor, for a 900 RPM motor.

This is the hell of a "3/4HP motor", it is rated for 10 amps at 110V
and easily blew a overload switch on my outlet bar at startup. The
less honest people would rate it as a 1.5 HP motor.

The other bad news is that there are supposed to be three handles on
the crank that lowers and raises the spindle. I have all threee,
however, two holes are somewhat stripped. One hole is fine, so I can
raise and lower the spindle.

Thread looks like 1/2"-20 NF, and I have a corresponding tap, though I
doubt that I have a die for the handles. I will try to re-thread holes
and see if that would help.

The mysterious pedal turned out to be for raising and lowering the
spindle. It's great for quick hole making when I use two hands to hold
work.

I think that I will upgrade my basement 120v circuit to 20 amps,
though it is not necessary for the DP, but it is a good time to do it.

I have an 1150 that I have used on and off for the past 17 years. It
had a 3 phase motor 1725 rpm when I used it sometimes for 8 years.
That place went out of business so I bought a bunch of their tools. I
installed a single phase motor I had laying around. I am sure it is a
1725 rpm is on it. I have never had any issues drilling with that
speed. It may be a waste to get a slower motor. Maybe not. But I drill
wood usually. Maybe you need slower for big metal holes.

Helicoil for the handle problem.
