I have a little problem:
In drilling and hollowing out a peppermill, the piece sliped in the chuck before I could finish my work on the end (it was held by just the chuck at this point). Is there a method to realign to the original axis? I have a 1 1/16" hole down the lenght and tried to use the bit on the tail stock to re-orient the work, but that didn't work.
Any advice is welcome :)

You might try a ballbearing tailstock center with a cone-shaped attachment like the one by Oneway. That oughta work.

That's not the say I would actually do it on my lathe, though. I have a laser permanantly mounted over my lathe. I would use the laser, aimed at the free end of the turning, and rotate the lathe by hand, to locate the centering error. Light blows with a mallet or chisel handle will bring the piece closer to center. Then the laser is reset, and you do it again. When it gets really close, place the laser so it projects a semicircle below the work (half on the wood), and you can detect errors down to a couple of thousandths.
Another way. Move the tool rest maybe an inch or so away from the right end of the work. Use a square shaped tool and wedge it between the rest and the work with the chuck almost tight. You are not cutting, you are moving the free end of the work. The wedged tool will vibrate while the work is turning slowly. When it is centered you will feel it.

Evening Berry: If that doesn't work, You might try driving a 1 -1/16" dowelrod into The hole, re-mark the center, and try the tailstock again.
Another way, is to get the piece as close to centered as possible, then take a pencil and lightly touch the the piece close to the end. It will only mark the high side. Adjust the piece so that the high side moves closer to center. Keep doing this until you get a line all the way around the piece. At that time you have it centered.
Hope one of these work for you.
Good Luck,

Thank you Barry, Leo, (the other) Bruce and Bill
I appreciate your advice. I had made a half hearted attempt at one of the ideas, but wasn't sure that I was on the right track. Now I have several ways to get this right.
I appreciate all your thoughts.
Have very good days,
John
John,
Now you know that every one of us have lost a few pieces out of the chuck, too. Otherwise; we wouldn't have so many ideas on how to recover from it.
