removing a tailstock taper

[Vinny]

Then the MT2 you're putting in there may be too short. Try putting something in there, like a nut, while it's fully retracted and see if an MT2 will go in and seat. If it doesn't, crank in out a little and see if it seats. If it does, crank it back in and it should release it and you'll know that your MT2 is too short. If you have something currently stuck in there, remove the quill and put a punch or rod in the hole and tap it out with a hammer. Heating the quill may be necessary - it was the only way to get a chuck out of my Logan when I first got it.
