Tailstock - Grizzly G0765 Owner's Manual

Tailstock

The tailstock is typically used to support long
workpieces at the side opposite the spindle, using
a live or dead center. It can also hold a tapered
drill bit (or a drill chuck with a regular drill bit) for
boring holes. Unlike boring done with a drill press
where the workpiece is fixed and the drill bit
rotates, the drill bit in a tailstock remains station-
ary while the workpiece is rotated by the spindle.
The entire tailstock can be repositioned and
locked in place along the length of the bed. An
independently controlled offset adjustment allows
the upper part of the tailstock to move perpen-
dicular to the bedways so it can be aligned with
the spindle center (for concentric turning) or offset
from the spindle center (for tapered turning).
The tailstock quill also features independent
adjustment controls that allow it to be advanced
toward the spindle or locked firmly in position.
