I had a lot of good comments with suggestions on how to remove the Jacobs chuck with the 33 Jacobs taper from my drill press. I waited until I had a replacement, then this is what I did:
I found a 12" Craftsman adjustable wrench in my drawer. I closed the jaws down so that they were a loose fit on the shaft above the chuck. At that point, I noticed that the jaws were TAPERED! So.... I got a mallet, and tapped the handle end, and the taper on the jaws popped the chuck right off!
I now have the new chuck on, and did no damage to the drill press.
