Removing the chuck from my Delta drill press


Hi,
I have a 16.5" floor mounted Delta drill press with a wobbling chuck and need to remove it. I've tried tapping the chuck with a hammer but it won't come off.
Before I get really agressive, I thought I better ask if this is the right technique for getting it off or is there another way? If this is the right way, how hard should I hit it?
Thank, Dave.

You may want to go to your auto parts house and get a ball joint removal fork. If you beat too aggressively with a hammer directly on the chuck there is risk of bending the quill shaft.
Some stores even loan them.

I've heard this advice before. This is NOT the way to do it. Spindle and/or chuck damage can result. There are essentially three mounting methods. (1) Screw on. This method is often used on smaller tools. Not likely on your Delta. Male taper on the end of the spindle that fits into a tapered hole on the chuck. To remove these, chuck removal wedges are available. These are slipped around the shaft just above the chuck and squeezed together with a C clamp, driving the chuck off. This avoids the beating and damage associated with other methods. (3) The chuck is mounted to a taper shaft that fits into the spindle. If you have one of these, lower the spindle. There will be slots on the side of it to take a drift key. Even after removing this from the spindle, you will still need the chuck removal wedges to get the chuck off of the shank. Generally though, Joe Homeowner will not want to invest the time or the money in the proper tools (about $20.00) and will take the expedient rout, take a hammer and beat hell out of it.

CW is right on target, although he left out something.
For the chuck that is mounted on a male taper - whether it's on the spindle itself or on an arbor inserted into the spindle - there can be other things holding the chuck on. One is an external threaded locking ring, another is a locking screw inside the chuck. The locking screw is likely to be LH thread.
The simplest thing to do is to get the owner's manual and/or parts diagram to figure out what might be holding it.
The chuck removal wedges are, from MSC, $6.65 a pair.
