Me chuck is stuck!!

Hey all, im looking for some help with my lathe. I have a Yates American j-170. I am having trouble with getting the spur center (Hopefully thats right) out of the head stock. I have a Nova chuck that i am wanting to put on but cannot seem to remove the center. Anyone familiar with this lathe at all?

Thanks,
Mark

i use a length of rod and light hammer blows from the back of the spindle (hitting the rod not the lathe spindle) taps out no problem most the time but some times it can take a bit of a wack (i keep my hand close to the spur so i can "catch" it)

The usual tool for removing a spur center is a knockout bar.  If you don't have one, you can easily make one.  All you need is a length of steel rod with a diameter slightly smaller than the bore of your spindle - 3/8" is usually fine, but the bore does vary from one lathe to another.  Slip the rod into the outboard end of the headstock spindle, and snap it toward the tailstock - that should dislodge the spur center.

After removing the spur center, you may need to clean up both the interior of the spindle bore and the spur center morse taper.   Fine emery cloth should do the trick.

Finally, finsh the project by adding some bling to your new knockout bar.  Turn a wooden knob that will fit over the end, and then glue it in place with a little epoxy.

I'm not sure if that lathe has a hollow spindle, although you can still get manuals for it.
There are a few owners of these machines at the Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register, they may be able to give you some information.
If you do have a hollow spindle, a knock-out rod is the preferred method.
here is a recent thread where another member was having the same issue with his machine. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register

In addition to this forum a local woodturning group can be a tremendous help for turners at all experience levels.  An Internet search for your area may help you find one.

First response in any " stuck" situation should be an overnite soak with "Liquid wrench" down here in the South.

I had a lathe once that did not have a hollow spindle.  I drilled the spindle for a through hole so I could knock out the spur center.  For that lathe it worked fine.  It was a large diameter spindle.
