ABSTRACT:
A reference stop for use in a lathe having a movable chuck and a draw tube adjacent to the chuck. A movable backstop is provided for rectilinear movement within a sleeve. The sleeve is inserted through the chuck of the lathe and extends into the draw tube. A threaded rod is attached to the backstop and extends outwardly from the sleeve, into the draw tube, and in a direction away from the chuck. The threaded rod is turned by a wrench and driver combination, and turning of the threaded rod causes corresponding rectilinear movement of the backstop in the sleeve, thereby allowing for a workpiece reference stop which is adjustable with respect to the chuck.
