For Axminster chucks (an others may be the same) there are four components
to consider:

1. The chuck body - the heavy bit.

2. The backplate or insert. This part matches the screw thread on your
headstock spindle. If you buy a new lathe you just change this part.
3. Accessory mouting jaws http://www.axminster.co.uk/default.asp?part=MTGJAW
You must have at least one set of these, but for quicker changeover you
might want one set for each set of jaws you have.
4. Jaws. http://www.axminster.co.uk/default.asp?sub=208 These mount onto 3.
above with two screws. I use the gripper jaws a lot

The chuck above comes with items 1, 2 and 3 as standard, you buy what jaws
you want.

Hope this helps

Also note that Axminster have several chucks which can take the same
jaws.

the
same jaws?
