How do I remove this chuck - 1930s WT Drill Press

[MayerMR]

Hey fellas,

I'm interested in replacing this Jacobs keyed chuck with an Albrecht keyless or Wahlstrom automatic chuck (not certain I can do a Wahlstrom chuck though), but I'm not entirely sure how I remove this. It looks like I need two pinner spanner wrenches - one to hold the top collar in place and one to rotate the lower collar on the chuck?

Thoughts?

In a perfect world that would work since that is the design. In reality if that chuck has been on there since new that may not happen. You could buy a set of Jacobs chuck wedges: https://www.mcmaster.com/chuck-wedges which would fit between the top of the chuck and the lower collar. Squeeze with a C-clamp or remove the chuck and spindle and squeeze in a vise--Some WD40 or other penetrant may help. A last resort is to open the jaws all the way and drill through the top of the chuck, apply penetrant and let soak for a while, then insert a punch into the chuck and drive out the spindle. If you have an arbor press that may be kinder than a punch and hammer.

Careful, the collar may be attached to the chuck. Use the model number to verify.

I have a old Craftsman drill press that has a collar on the top that is a safety to keep the chuck from wobbling off the taper with side pressure. You need to the the manual on that drill press or chuck to see if you have that collar on that one. Most cheap China drill presses don't have that collar to keep the price down.

Here's a video that might be helpful. I think what you have is the same style as shown in the video.

Thanks everyone! Pete that video was very helpful...hell, everything Tubelcain does is helpful...

It's a sin that they are not still made that way. Drum sanding on a press is common and all the warnings not to mill on a DP would no longer be a safety issue, though DP spindle bearings are not designed to take a side load. I would guess it was a cost issue.
