If your tailstock barrel is not aligned with the spindle, any center (including 
a perfectly good one) is going to make work want to walk out of the chuck.  It 
will force the end of the part to rotate around a point that is not on the 
spindle axis, and that means the part is being rocked back and forth in the 
chuck once per revolution.
