    Default Tailstock / spindle allignment qt-18

    I had to turn a shaft recently and was appalled to see that over 7 ½ inches, I had a .013 taper. I put this together for my own notes, but I thought I would share what I did to fix and get it to within .0002 over 7 1/2 inches. There are 2 ways to adjust the tailstock to center with the spindle. At the end of the quill there is an eccentric that you can rotate, this maybe good for .005+-, but not going to fix my problem. The second way is to move the base that the tailstock sits on. There are 8 - 12mm cap head screws and 2 push/pull bolts that you can use to get things in alignment. I actually started w/ the head stock, I had a .007 taper with out any tailstock involved so I adjusted using the same push-pull style bolts in the tailstock.
