Why can't I get the "wobble" out.

For some reason I always seem to have a very slight wobble in my work. For example, I have just started turning a pepper grinder. So, I turned a ten on on one end and put it in my chuck. I bring up the tail stock to keep ni ce even pressure on the piece while I tighten the jaws. Now I turn down th e blank to where it it is a cylinder and should be true. But even with the tail stock in I experience this very slight wobble. I mean if I bring the tool rest up and take a tool, say a skew, and bring it closer to the piece it will start hitting it unevenly, sort of a tick, tick, etc. And no matt er what I take off it still does this. Could I have an issue with my lathe ? It's a Jet 1014.

Have you checked that the tailstock is aligned with the headstock?

Try putting a piece in the chuck and not using the tailstock. If you still get the wobble, check the headstock bearings, or try turning something between centers without the chuck, in case its the chuck.

That is a good hint - tapers are made with offset tailstocks

Is your lathe level ? or is the bed twisted ? Put a level on the ways at the head and tail - then lengthwise.

Jack up a leg or two to make it level. Wait a week or two and check again as the twist starts to come out - might need adjusting.

How do I do that? Just bring the two together and see if the points meet? If they aren't, how is it adjusted?

I'll check the other points today.

Thanks, Jim

There should be a bolt on the bottom of the tailstock. Loosen it and get the points in alignment, then tighten the bolt. If it gets out often, you can buy an alignment tool which has a Morse taper on each end. Loosen the bolt and slide the tailstock up so that the tool holds it in alignment, then tighten the bolt.

Some lathes may have another method for holding the tailstock in alignment--I've only owned three so cannot say about the many other brands.

On that Jet lathe, put your spur and revolving center in as if you were going to surn a short spindle.... With the points about 1/2" apart, slowly crank the tailsock out until thepoints are almst touching.. (I like them about a paper thickness apart) If they are not perfectly point to point, first check the adjustment on your swivel lock pin on the headstock... All this is covered in your manual..If you've misplaced yours let me know and I'll pull mine out for specifics..
