I like to replace the 1/2" chuck to 3/8" chuck from an old Delta
floor drill press I brought yesterday. Unlike the modern drill press
you insert a drift key into the slot of the quill and hit the chuck
arbor out. This old Delta drill press doesn't have a slot in the quill.
Further, can I replace the present 1/2hp to 3/4hp or 1hp motors?
I have posted both drill press and vise in apbw.
I don't see the point in doing either one. If the chuck functions fine, what
would be the point of going to a smaller one? 3/8" is smaller than anything
I'd want on a drill press. As for motor horsepower, not to likely that you
will run out of power. A 1/2 horse is plenty specially if you are going to
be doing things so small that a 3/8 chuck would be adequate.
Thanks for the website. The drill press came with a six-pages
operating, maintenance instructions and part list. The pics
are too small to determine if it is threaded or Moss taper mount.
I have checked the spindle and there is no runout and would
not want to mess it up.
I have been searching for more than two years in estate and
garage sales after seeing it in David Marks DIY Woodworking
show. This drill press is very heavy for a small 1/2" chuck and
would like to replace it with a bigger Jacob's chuck.
Thank you again.
Can you determine the model? If so, I probably can tell you whether it is
threaded or Jacobs Taper style... Either way, replacement chucks are
available assuming yours is ruined...
Is it a floor or bench-top type?
Forget about replacing the motor... It is probably possible... But you
might as well buy a new drill press from someone for about twice the cost
and have an all-new machine.

14" B Model floor type. S/N 123-6654. The chuck is Chicago Supreme
0-1/2", in good condition except, it cannot be open or close (not
tightening or loosening) with your hand but with chuck key. I would like
to replace it with 0-5/8" chuck.
I paid $100 at an estate sales, replacing my one yr-old 13", 3/4HP Central
Machinery floor type. I can't stand the clanging sound and vibration
at high speed. This old Delta is far superior to many of the newer drill
in the market. This Delta looks like the one use by Mark Davids in DIY
BTW, if you are familiar with old Delta, can I still get the 1/2" bore cast
aluminum steps pulley (P/N 985-A)? I need the original otherwise, I will
replace both pulleys (slight dents and wobbling at the motor side).
Thanks you very much.
(I use to work on National Acme, Wickman, Index and other multi-spindle
screw machines and all types of drilling and attachments)
Sounds like a relatively old machine. Unfortunately, I don't have any
records on a 14" Delta of any kind... The easiest way to determine if it is
a threaded chuck is to lock the largest allen key you can in the chuck with
the long end sticking out and away from the chuck. With the motor set to
the highest possible RPM (most resistance on the chuck when turning by
hand), smack the allen ket so that it spins the shuck counter-clockwise. I
personally use an aluminum hammer to do this. NOTE: Make sure you are NOT
smacking the spindle or chuck in any way. You simply want to rapidly spin
the chuck... With the motor and sindle's resistance, it will unscrew off
the end IF and only if it is a threaded chuck.
Now... If it is a Jacobs Taper chuck, you should be able to see the top of
the taper just above the chuck and just below the spindle. In that case,
you can probably use a J6 wedge set and remove it. Let me know if you think
this is the case as I can eMail you a file to show you how to do this...
But I'll need a valid eMail address to do so.
You can get brand new Delta machines relatively inexpensively... Delta
DP400 is around $430 new from a number of sources... And it's a 16.5" unit
Not quite as heavy as the olkder machines, but no lightweight either... The
same exact machine can be had used for less as the DP400 or 17-900.
Not sure... Detla is good about stocking parts for their machines, but
because I've never heard of yours (and I doo drill press stuff all day) I'm
a bit worried that it is not supported any longer. You will have to contact
them or a dealer directly on that front...
Wish I could be more help!
Interesting units... Some are really complex too. I like seeing the units
other folks make but HATE working with them. Some with CV joints and all
that are a real PITA and expensive to maintain... I don't even sell CV join
heads because of the stigma that is developing around them.
Much success to you and feel free to eMail me for that chuck removal file...
It's a bit rough around the edges, but should help.
