Default Drill Chuck Question?

Not sure if this is allowed, so if inappropriate please remove...

I have a Wen 4210 drill press. I've been using it to polish scroll projects over the past several weeks.

I went to drill some holes with hole saw blades the other day (you may remember the shop vac project with the circle cutting jig), and the chuck kept falling out.

I hammered it back in but after every hole cut, the chuck would fall out.

I was told it might be the bearings, or dirt. I've cleaned the shaft but not the inside. I don't see how bearings could be the problem, but then again I'm not too mechanically inclined.

Does anyone know what else would cause this?

Thanks as always in advance

Hi, Jessie; why wouldn't it be allowed?
Just to be clear, the chuck is mounted on a tapered shaft that fits into the quill on the drill press(?).
That would be the normal method but I have no idea how WEN's are designed.
Once the Morse taper is pushed up into the quill, you normally need to insert a special device...sort of a wedge thing...into a hole in the quill to get the Morse taper back out. Falling out might happen if you put a lot of sideways pressure on the chuck. Other than that, hopefully someone else has some thoughts. I think quite a few of the members have WEN drill presses.

What Dan said is correct. My milling machine also has a threaded rod that extends through the quill and screws into the end of the chuck arbor. I don't think there's one on my DP. I think it's just a friction fit. Check for burrs on the chuck arbor and then wipe the inside of the quill out with some solvent to make sure there's no grease or varnish that might have been put in at the factory to prevent corrosion. Then put the chuck in and press down really hard on a board.

careful you don't wash the lubricant out of the jaws

Not allowed because it doesn't have to do with Routing in any way. Some forums frown on extra postings not related to the sites main topic so I try to preface off topic posts just in case...

The Wen does not have an insert, screw or anything to hold the chuck in. You simply hammer it in.

Here are the instructions for installing the chuck - hopefully you can read them

DaninVan may have hit it on the head...

If you're polishing and using sideways pressure, it might just slip because of the taper and sideways force...

Thanks @Nickp

It happens now when I drill straight down not when I polish

I would think that either the quill or the chuck is worn. Given the fact that you would probably never need to put a new chuck on (unless of course the one you have is worn and are willing to pay for a new one) I would put a lot of red Loctite on the quill and hope that solves the problem forever.

When you start a thread (ask a question) you normally would post it under one of the Forum categories that you think is most appropriate for the topic, if you're not sure, just post it in the 'Lobby'.
One of the mods might move it for you, but it's not a big deal.
The Lobby is a freewheeling circus...

Not talking about the chuck but the tapered socket in the quill that the Jacobs or Morse taper fits into.

Questions like this are fine. It's in Tools and Woodworking sub forum which is also good. You usually need other tools besides a router to make things and most of us are tool junkies anyway so we're good with questions like these.
