The tail stock and the headstock are opposite one another and in normal conditions are aligned on the same center. For cutting a taper the tail stock can be adjusted off center. The tail stock is positioned behind the carriage and mounted on the same ways as the saddle. It can be locked in any position on the ways.

To set the tail stock; on or off center there are offsetting adjusting screws on the base. The head consist of the quill (ram or spindle are also names used), quill lock, hand wheel, and a clamp lever or nut. A clamp lever or nut is used to tighten the tail stock in position on the ways

The quill has a standard Morse internal taper for holding a center, Jacobs chuck or any other tool that has a standard external Morse taper. Graduations have been engraved on the quill spindle to measure the length that the ram has project from the head.
