I was turning a spindle and using the tail center and the spindle was turning true,,when I removed the tail stock I noticed it wasn't true running in the chuck which is a super nova,,,as a matter of fact after it stoped I could pull on the spindle and see the play or movement in the chuck,,i removed the insert and thought it might need tightening but it would not go any farther in,,i just bought this lathe about 6 months ago,,its a jet 1642,,im just wandering if its in the spindle or the chuck itself,,if you do not have anything chucked up it seems to be running true,,but it does have play in it without the tail stock,,can anyone help,,,
