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.

—If the tool does not come loose by retracting the quill, extend the quill and use a drift key in the slot (see Figure 39) to remove the tool.

To offset the tailstock:

1.Loosen the hex bolts underneath both ends of the tailstock to release the clamping pressure between the top and bottom castings (see Figure 40).

2.Rotate the adjustment set screws in opposite directions for the desired offset (see the illustration in Figure 41).

Offsetting Tailstock

The tailstock can be offset from the spindle centerline for turning tapers. Move the tailstock top casting toward the front of the lathe to machine a taper at the tailstock end. Conversely, position 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 are
arbitrary. For a precise offset, use a dial
indicator to check quill movement while
adjusting the screws.
