I was lucky in finding an old Gosinger floor model drill
press is good shape:
The Spindle head postion has 6" of travel.
THe quill feed travel is about 4"
The BASE is adjustable about 24" (knee style - like
a full size milling machine).
Foot print: roughly 18" x 24" (6.5' hieght)
feed stop... positive stop.
Four pulley position - leather belt drive, with a quick change
feature. I'm using a more modern belt. (I do not have the address
handy, but there is a shop that makes replacement (nylon?) belts for
old machines, cost about $25 [Do not pass on that old drill press
because it uses a leather belt!]
800 rpm 110v motor. Maybe be rated at only 1/3HP... but doesn't slow
down for anything (3/4" drilled through 2" steel plate... ;-)
SURPLUS BUYING HINTS:
Best to "test drive" a machine first, if possible.
Also if you can mentally picture a "L" shaped beam: which is
attached the drill check on the short end, with the long end
fitted with the dial indicator. Quick spin around the table
top will show if the head is perpendicular to the table. Some
drill presses may have been abused as a small arbor press...
bending the head support.
If the head is bent back 2 degrees, may not seem like much...
but drilling though a 3" section of aluminum will produce
an error of 0.105"
Also TRY to flex the head and see what sort of play you notice.
(Dial indicator, with a magnetic base, can also give you a good
idea of the condition of the bearings)
Common spindle size? Some old machine have some really odd
sizes, thankfully the one I bought had a 1MT (#1 Morse Taper)
fitting. (didn't even think about that until I got it home! Whew!)
I found this from the machine shop, who's owner was retiring,
at the same time I bought my mill and lathe. Paid about $400
for it, which originally I thought was too steep. After
comparing it to drill presses, seems like a bargin in the
long run.
Sorry about being so wordy, but thought I'd pass this along.
Had this drill press been at a Auction, I would have probably
not wanted to pay more than $50 for it... also it is HEAVY.
200 pounds of cast iron make it very stable, but if I ever move...
DRILL PRESS VISE:
Splerge on a good PALM GREEN drill press vise ($80). ;-)

For TAPPING HOLES: that adjustable table/head are great. I still tap
by hand, but have a piece of 3/8" diameter metal about 3" long which
is ended in a 60 degree point. Bring the head down to locatd the hole
to be tapped. Then move the head back up, and use the guide to keep
my hand tapping tool centered over the hole. Wow I finally have nice
STRAIGHT tapped holes once I got the tap started correctly. [This
is old hat to some, but glad to pass it along to anyone still learning...
like me!]
