Lathe chuck

Dusty MI · Sep 10, 2015

I have an old Seneca lathe, 6" swing, 60" bed, or something like that. The 3 jaw chuck has gotten hard to open and close. It feels like it needs to be taken apart and cleaned. I took all the allen screws out but do not see how it comes apart. Shouldn't it come apart when all the screws are out ?
The chuck looks like the one on the lathe that Lance pictured.

Those jaws should come all the way out. Just keep opening the jaws until they are free, then you can apply oil to the scroll. The jaws should be numbered, with a corresponding number on the chuck. Number 1 goes in first.

I've had the jaws out but would like to get to the scroll.
I'll take the jaws out again see what I can do from there.

Not sure, no photo, but you probably have to remove the chuck and then take the back plate off. Make sure to mark it so it the two halfs go back in the same spot

If it is 1inch 8 tpi I have a 6 inch in an eBay auction rifght now. Jaws are copper coated steel.6inch diameter 3 jaw.

I got it all apart yesterday, cleaned it up and greased it, put it back together. The jaws will close without to much of an effort, but it is hard to close them. It appears that the problem is with small gears that turn the scroll gear, and I didn't see a way to get them out. They seem rather loose.
I can e-mail pictures, but don't post them.

Thanks,
Dusty
