Any luck getting a stuck chuck un-stuck?

I have seen a lot of people use the key for leverage and I have a wooden stick that I put between partially open jaw gaps for leverage. Neither really seems like a good place to put a large amount of force without bending something.

What about putting a bar of aluminum or brass if you have it (softer than steel)at an angle onto the edge of one of the large key holes on the body and giving it a quick, sharp rap with a hammer?

Good luck,

Just get a bigger wrench and pull steady.

That works on my faceplate that likes to get stuck. I haven't had trouble with my chucks but the same wrench would fit the adapter and therefore not stress the chuck.

>Don't know what kind of an adapter you have but on the Oneway there are no flats on the adapter to use a wrench. One could possibly make a special wrench (there is a name for them) that hooks into one of the locking holes on the adapter. Looks like a big G with a handle.

>I went back in and had a look at mine with the key inserted and I have to agree that your method probably wouldn't be all that bad.

I think the plastic washer is a real great device to prevent this from happening unless you want to make sure the chuck is really on tight say for reverse operations like sanding.

Thanks!!

>Thanks Bill and everyone for your suggestions.. I went out and tried tapping into one of the holes, but no early luck, so I took my nice new hammer and opened the chuck jaws, put the hammer neck "in" the chuck jaws, pushed down on the handle, and it worked like a giant chuck key.. Maybe the PB Blaster overnight played a role, too. And yeah a spanner would have been handy!!

Don't do what I did!

>I usually put the key in the hole and lock the shaft and git the key a bump with my hand. Work most of the time. When it didn't work, I did not want to put too much pressure on the swivel head of the key, so I put the breaker bar for the lathe in the hole in the chuck and gave it a jerk. It worked, but the bar is about a half inch and the hole is about a 7/8" The bar burred the side of the hole. The key no longer turned smoothly. Fortunately, I only did it once and was able to smooth it out with some 400 grit sand paper.

I would think it would be better if the bar exactly fit the hole. Better yet, use the plastic washers and don't get it stuck. I find that if you seat the chuck firmly to start with and don't let the rotation of the lathe "snap" it home, they don't stick as badly.
