For Machines Mfg. Since 5/11

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 shown in
Figure 41 to remove the tool.

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.
