How to Remove Chuck on Clausing Drill Press

[markT]

Any one know how to get this chick off a Clausing Drill Press? It’s a Jacobs j33. Question is the piece above the chuck. Does it thread on?

Probably screwed on, there is a screw from the inside of the chuck in to the spindle, open the chuck all the way up and look inside. May need an impact driver to remove that screw,(should/maybe left hand threads) holding the spindle to spin off the chuck might be interesting

Have you run the quill /spindle all the way down and looked for a slot to put a drill drift in and drift the chuck out?

Most chucks have a taper to attach them. You will need a set of chuck wedges to remove it. McMaster has them.

I figured it out.. It threads on and I used punch to loosen the threads....The some mild heat and a screw driver to get it out / off the taper.. The chuck is screwed up ( used drill press) the jaws are no parallel.. Might be time for new one..

What it appears to me what you have there is a drill chuck with an adaptor mounted on it. I think you still need a set of Jacobs chuck wedges to remove the adaptor. The designation "J33" is a Jacobs taper mount, not a thread.

Those Clausing’s are a different beast. Mine is just the same as the OP’s, threaded collar but it’s not an adapter in a standard chuck. The threaded collar on these chucks is for both removal and retaining the chuck. There used to be a number of these chucks available but no one seems to make them with the collar anymore. Edit: These are still available new from at least a couple of the large machining/tooling suppliers. The original chuck has an integrated extension on the body machined to fit a circlip to retain the collar. You could probably remove the collar from the original chuck and leave it threaded on the spindle if you wanted to use a standard chuck and remove it later.

Supposedly a reason for the collared chucks was the collar acted as a retainer to keep the chuck from coming off with side loads.

Whatcha got and are they for sale? I’m sure with all the messed up chucks you hear about on these things I’m sure they’d sell in a minute. I might be interested in a spare for just in case down the road.

My Clausing had minimal use. It came out of the prototype shop of a large electronics manufacturer in Seattle. They closed the shop and started contracting out the work to Asia. Typical story these days.

And, re-build kits are available for Jacobs Drill Chucks.
