The inside of the quill has the female morse taper which grips the live centres male taper which you have fitted. To eject the live centre either:
-
continue to wind the tailstock wheel in so the quill disappears into the tailstock. There will be some slight immediate resistance as the quill goes in and as you continue the two morse tapers should slide away from each other and the live drive will be ejected revealing the same recess as you have on the headstock.
Or -
use the knockout bar and insert into the end of the quill at the handle end and tap the live drive out. If you have not used the lathe for a while this might be best as the tapers may be gripping
If your knowledge of how lathes work is very limited it would be good for you to join a local AWGB club and watch some demo’s and chat to members or else get a good basic book like Keith Rowley’s one. Or else go to your local Axi store and chat to them.
If you are anywhere near the High Wycombe branch drop in on a 2nd or 4th Tuesday and meet the ‘Turning Tuesday’ group at which I am a volunteer (hobby) demo turner
