======================
I have known for several years now that my little 1/4 hp, eight-inch swing
drill press was inadequate for all of my needs (especially the short swing)
My current project has put a head on this, so when providence lined me up a
suitable item, I followed through.
I now own an old Rexon RDM-100A drill press, 1/2 hp, 14" swing, which I
acquired for sixty bucks. Not a Gunner/Iggy "take the machine, the car, and
my teenaged daughter" deal, but I am very happy.
It is still a bench-mount unit, but substantially larger than my old Delta.
It is sturdy enough to do what I need to do with it, but still portable
enough to yard into the carport when I need to do a job outside.

There is still a Rexon company, and they may be able to provide the manual. But
the RDM-100A of today is not quite the beast you have.

They may have a US distributor. The URL doesn't work, but I didn't try the
phone number.
It also uses an idler pulley, so I now have 16 speeds instead of five, and
can be more precise in my feedrate selections.

Something that I think is pretty neat is the built in location for a light
bulb (I'll need to work a spotlight in there on a hinge).

Use a small flood, not a spot, or the light in your eyes will interfere.
This is also the first drill press I have owned which uses a morse taper
(MT2) to accept the chuck arbor, so I will be able to mount drill bits using
collets in those cases when the chuck doesn't grip them tightly enough (what
all do I need to start working this angle?)

I see rust bleeding down the quill. It could use some cleaning and slathering
with Vactra #2 way oil. Start with WD40, as there may be water up there. Or
leave out in the sun for awhile.
The best solution to drill bits slipping in a chuck is to replace the chuck,
which is easy on a press with a taper. Most kinds of collet don't grip tightly
enough to prevent spinning, and spinning will ruin the collets.
I was able to figure out that this machine is about the same as the current
Harbor Freight unit 38142, and have the manual for that machine. That led
me to figure out the assumed function of the little chrome-plated handle
shown in this picture, but despite loosening the two thumb screws, the
handle doesn't want to turn more than an 1/8". Where should I squirt some
lube to help free up this mechanism?

The handle looks to be the release to allow the motor to move closer to the head
so the belts can be changed. It may require disassembly, cleaning, and
lubrication to free up.
