If the arbor has an open hole in the end, a screw can be threaded into the end of it to provide a solid surface for the quill pin to push against when the quill is retracted for tool removal.

To install tooling in the tailstock:

1.With the tailstock locked in place, unlock the quill, then use the quill ball handle to extend the quill approximately 1⁄2".

2.Thoroughly clean and dry the tapered mating surfaces of the quill and the center, making sure that no lint or oil remains on the tapers.

Note: This helps ensure that the tool seats

properly and has minimal runout.

3.With a firm and quick motion, insert the tool into the quill. Check to see if it is properly seated by attempting to twist it by hand—it should not twist.

4.Unlock the tailstock and move it until the tip of the tool is close to, but not touching, the workpiece, then re-lock the tailstock.

Note: The tool may seat further when it is pushed against the workpiece.
