3.Use the quill handwheel to feed the quill out from the casting approximately 1”.

Note: The maximum quill travel is 4 34", but we do not recommend extending the quill more than 2" or stability and accuracy will be reduced.

4.insert the center into the tailstock quill.

5.seat the center firmly into the quill during workpiece installation by rotating the quill handwheel clockwise to apply pressure with the center engaged in the center hole in the workpiece.

Note: Only apply enough pressure with the tailstock quill to securely mount the work- piece between centers. Avoid overtightening the center against the workpiece, or it may become difficult to remove later, and it will result in excessive friction and heat, which may damage the workpiece and center.

Removing Center from Tailstock

to remove the center from the quill, hold onto it with a gloved hand or shop rag, then rotate the quill handwheel counterclockwise to draw the quill back into the casting until the center releases.
