One in a while one wants/needs a chuck on the tail end of his lathe. Usually a center on the tailstock will work, or a steadyrest, but not always. Drivelines are among the things that often call for use of a tail chuck. This one was thrown together to work as a tail chuck. The arbor is turned on the lathe to a #5 Morse taper and the head is mounted on two Timken tapered roller bearings. the end of the arbor is threaded for a bolt and washer to set the backlash in the bearings. A centering plate is then provided to mount an 8 inch chuck.
