Tailstock ram must also be level. You'll find a lot of tailstock bases worn on the front end from heavy handed operators shoving them around. You might have to shim
it level and then you should shim it so the center is .0005"- .001" high.

Assuming the twist is out of the bed here's an easy one to set the tailstock.
Say the diameter of the? quill in the tailstock is 1.4985 inches. Turn a short piece of metal in the chuck to that dimension. Put the tailstock at the far end and lock it down. Set up a dial indicator in a tool post and zero it on the piece you turned to 1.4985. Run the carriage down and put the indicator on the tailstock quill. It should read zero. Now you just tweak the tailstock alignment screws until it reads 0. You don't need an x feet long bar to work with, just a 1 inch stub of scrapbinium.
