Topic tags/keywords: drill press chuck

I have a Delta 12” bench top drill press. My chuck has started to become difficult to tighten up. I’ve opened it up as far as it will go and have used compressed air to blow out any crud that may have been there, that didn’t help any. I’ve sprayed it with some dry lube – that didn’t help. It basically feels like it’s “skipping” as I turn the chuck key.

I’m at the point I need to replace the switch as well because sometimes it doesn’t turn off.

Between the two issues, I may be better off just getting a new machine – but would rather fix it if I can. Any suggestions would be appreciated.

Thanks in advance.

Is it a chuck key problem? I can’t imagine what else would cause this “skipping” action.

As for the switch, that should be as fairly easy replacement with a switch from a good hardware store. You might have to do a little adapting, but it’s still better than a new machine.

Pictures might help a suggestion in the switch dept.

I would spray some WD40 in it and work it open and closed a few times if that don’t help replace it. You can get one cheap at Wholesale tool it’s likely as JT33 but check first. Russ

I agree with Les, try another chuck key.

As the fellow lumberjocks indicated – check the chuck key – are the teeth on it worn so that
it feels like it is skipping or is it the chuck ?

I’m not in the States so can’t comment on replacement part prices etc.but I had a
situation where I bought a large but cheap Taiwanese drill press and after
a year I noticed wobble while drilling – final conclusion was that the chuck
was at fault , so I bought a precision hand tightening chuck – much better now
but I’m unhappy that I didn’t pay a bit more for a more precise machine
in the beginning. The old rule I learnt a long time ago – always better to cry only
once – when you spend the money (you’ll forget about the pain very quickly
if everything is working according to your expectations)

The chuck key still looks in good shape. I know I have another one in a drawer somewhere so I’ll still check out the key. I’ll also try the wd40.

The switch should be easy enough.

I was really hoping someone would say chuck it to the curb and get a new, bigger and better drill press…. Oh well Christmas hasn’t come yet. :-)

Thanks for the replies fellas. I’ll let you know how I come out.

Second the WD-40 flush. My drill chuck was not working right, so I just kept flooding it with WD-40 spray while working the chuck. Finally, a bunch of junk came out. Works good now. But with all the other issues, maybe you should ask Santa for a new one : )

Spent a little time doing machine maintenance today. Did the WD-40 flush and got a ton of gunk out of the chuck. Seems to have cured the “skipping” issue. I’ve also ordered a new switch so between the two solutions my drill press should be good for good while longer.

Thanks for the help.
