I bought a second hand delta lathe (the sort on legs). The seller also
included a tailstock chuck. I have attempted to use this a couple of times
and failed miserably. The chuck has a square end. The delta lathe tailstock
is round with no square to slot the chuck into. As a consequence it spins
freely. They guy I bought it from had definitely used it with this lathe, so
I am wondering what I am missing. How do I keep the chuck stationary.

Square end, as in a taper with a couple of flats? That's fairly normal
with self-ejecting tapers. Make sure you crank the tailstock quill forward
a bit so the taper will seat properly. Advance it until you feel it seat,
then a quarter turn. It may mean, as it does on mine, that you can't begin
drilling at the zero mark, but you want to make sure the taper is seated
properly to center, and the quill tightened to reduce gratuitous movement.
To remove, all you have to do is crank the stock back, and it will eject.

sorry, what is a quill?,

no the chuck is round for most of its length, then at the end is changes to
a square. The square if I remember correctly is the sam diameter diagonally
as the round bit. I cant seen anything at all that you could seat it into.

I am wondering, are you saying that the morse taper has a tang on the end,
like shown on the small end of the morse taper on this drill chuck?:
http://www.lathemaster.com/Keyless%20Drill%20Chucks.htm

If so, you need to wind out your tailstock far enough so that the tang is
not pushing the chuck out of the tailstock barrel. Then the tapers will
match together. Right now you are probably bottoming out before the tapers
meet.

The quill is the tube that is revealed toward the headstock as you crank.
Sounds like you have a self-ejecting taper. You crank the handle until you
see about a half inch of the quill, then try seating the taper.

Clean the thing first, should it need it.

Senior moment.

How about a look at
http://www.wmhtoolgroup.com/JETGener.../JWL1442VS.pdf

Pages 22 and 23 show the exploded view of what you need to know about.
Sorry I didn't think of that earlier.

I had a similar problem with a drill chuck and simply ground off the
squared end and the morse taper fit fine.

Moggy,
The tang at the end of the taper can be ground off. You don't need it for lathe
work. The tang is there for the purposes of using the taper in a drill press,
and is thus useless for lathe work. If you take off the tang you can use more
of the quill travel because it will be less protruded when first seated.
