    That Drill Chuck is on Tight!

    I had removed and replaced my drill chuck a few times prior to sending my 17-950 in for service. They must have used a press or something because that guy will not come off.

    Bearing in mind that the temps here have been 100+ for a while and the service guys may not be at fault. I used a block of wood and a 16oz hammer to tap it as hard as I dared.

    Just in case the old freezer trick doesn't work, does anyone have any tips? I am going to give a keyless chuck a try (when I get the Jacobs off that is).

    Reciently acquired an older model Craftsman DrillPress (50s) and the Chuck seems to wobble abit. Bit it drill true and on the mark. Any suggestions for the Quill?

    Glen,
    The drill has a taper chuck holder.
    Have you tried spraying it with penetrating oil and letting it soak over night?

    Let me know which key-less chuck you go with, I've been thinking of
    converting my 17-950 also.

    Have you got a threaded extractor that you could use on the pushing motion rather than pulling? You know those used to extract bearings from shafts.

    It is the only idea I can have without seeing it.
    Best regards,
    Toni

    Do you have a slot and a piece of taper steel for removing? I can't imagine a chuck resisting that.
    Good luck with the keyless chuck. I think they are the pits.

    Unfortunately the chuck does not have a through hole to allow this but, thanks for the idea ;-)

    Lee Valley(?) sells the wedges for removing chucks. As well as others.

    What's the freezer trick? You got an empty freezer that big?

    I betcha heat would actually improve the situation, cold would just make it tighter. Stick a propane torch on it for a while. Not til it turns blue, just til its hot enough to burn your shoe when it falls off
    Why didn't I think of the pickle fork? Probably because I don't work on cars but, a neighbor does, thanks. I have freed tapers by placing them in the freezer for about an hour and then giving the joint a tap.

    If you want to remove the spindle adapter with the chuck attached, you use a wedge shaped drift pin to do so.

    If you want to remove the chuck from the spindle adapter, then you need that "Pickle Fork" that John is talking about.

    What you really want is two of these, they are usually fairly thin, look >> HERE << on how to remove your chuck.

    Cheers!

    Taper adapter to chuck is the trouble maker. I'm going to go borrowing a couple pickleforks I hope. Thanks!
