Default How do you remove the chuck on a Nu-way drill press?

I have bought a drill press from an auction. It works great the only problem is the pilot holes in the chuck are worn. I would like to remove the chuck to clean up the holes or possibly replace it. I am familiar with chucks with a Morse taper this does not have one. I do not see a name on the chuck. It is a Nu-Way drill press with some age on it. Any ideas on how to remove the chuck?
Thanks
Ben

Drill chucks normally have either a threaded joint or a Jacobs taper. I believe that most drill presses will have the Jacobs taper. To remove the chuck you need to use a wedge between the chuck and the spindle of the drill press.

You might see first, if there is a retaining screw inside the chuck, to assist keeping it on the shaft. A friend tried to remove a chuck on a DeWalt drill, and ruined the chuck before he noticed a screw that was installed in the chuck interior, into the drill shaft itself. When the screw was removed, the chuck came off easily!

Reversible drills use the screw inside to keep the chuck from unscrewing, all I've seen have been left hand thread on the screw.

Ben, how big of Allen wrench do you have and do you have a 1/2" drive impact wrench (rattle wrench)?

Do you see where I'm going with this? The threads should be right hand.

Worked for me

If you're not sure if it's threaded on or pressed onto a taper, you may want to try a combination of the suggestions above.

First make sure there isn't a retaining screw up inside it, the clamp the chuck as tight as you can onto a cut off piece of 3/8 or 1/2 inch allen wrench, the biggest you have that will fit, and then apply pressure with a wedge as you you use the impact wrench to jar it loose. I've seen spindles bent by people wailing on 'pickle forks' and 'drill drifts' trying to force a chuck to move. If it's threaded, it would most likely be a right hand thread, (retaining screw if there is one, could be left or right), but you might want to reverse the impact wrench back & forth a couple short bursts, which may help break loose a stubborn taper, with a wedge or pickle fork (split wedge) applying pressure.

It was a press fit taper nothing holding it from the bottom. We had to pull the spindle to be able to hit it hard enough to get it off.
Thanks for the help

The taper pin is still stuck in the shaft-it's morse taper on the 'upper' end and 'jacob' taper on the lower.
