Grizzly g0749, g0746 Removing Tooling, Offsetting Tailstock, To install tooling in the tailstock

Note: If the tooling has an open hole in the end, then a screw can be threaded into the end of the tool to provide a solid surface for the quill pin to push against when the quill is retracted for tool removal. Otherwise, removal of such tooling may be difficult.

To install tooling in the tailstock:

1.With the tailstock locked in place, unlock the quill, then use the handwheel to extend it approximately 1".

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.

3.With a firm and quick motion, insert the tool into the quill. Check to see if it is firmly seated by attempting to twist it—a firmly seated tool will 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.

5.start spindle rotation, unlock the quill lock lever, then turn the quill handwheel clockwise to feed the tool into the workpiece.

Removing Tooling

1.Use a shop rag to hold the tool.

2.rotate the quill handwheel counterclockwise until the tool is forced out of the quill.

Offsetting Tailstock

the tailstock can be offset from the spindle cen- terline for turning tapers. Move the tailstock top casting toward the front of the lathe to machine a taper at the tailstock end. Conversely, move the tailstock top casting toward the back of the lathe to machine a taper at the spindle end.

Note: The marks on the offset indicator (see Figure 49) are arbitrary. For a precise offset, use a dial indicator to check quill movement while adjusting the screws.

To offset the tailstock:

1.Loosen the tailstock lock lever to release the clamping pressure between the top and bot- tom castings.

2.rotate the adjustment set screws in opposite directions for the desired offset (see the illus- tration in Figure 50).
