I have a vintage Delta 14” drill press…I believe it is a DP220.

It came with a puny 1/4” Jacobs chuck (number 7).

I took a piece of wood and smacked the top of the chuck and ONLY THE CHUCK CAME OFF. The arbor is still tight in the spindle.

Now If I can just buy a bigger chuck that fits the spindle that’d be great….but I can’t find out what size arbor it is. So my question is….

How can I find out what sized arbor I have, or how can I get the arbor out of the spindle now?

Here is a pic I found on the web of the same chuck…I’m assuming it to be the same sized arbor as well.

If you strike out here, you might ask over at OWWM…those guys know their stuff.

Not sure what DP you have, but that is most likely a JT33 taper the chuck fits on (DP-42 is a Jacobs chuck). The taper should be part of the spindle and not separate from it. If you want to change it, you change out the spindle itself (instructions can be found here).

Open your old chuck completely. look inside and see if there is a screw head. If so unscrew the chuck from the shaft. (left hand threads) reuse the shaft by screwing on a new chuck.
