Tailstock - Grizzly G0782 Owner's Manual

To mount a non-concentric workpiece to a
faceplate:
1.
DISCONNECT MACHINE FROM POWER!
2.
Position appropriate device across bed ways
to protect them from any potential damage
from workpiece contact during installation.
3. With help from another person or holding
device to support workpiece, position it onto
faceplate and clamp it in place with a mini-
mum of three independent clamping devices
(see below for an example).
Be sure to take into account rotational and
cutting forces that will be applied to work-
piece when clamping it to faceplate. If neces-
sary, use counter-weights to balance assem-
bly and use a dial indicator to make sure
workpiece is properly positioned for your
operation.

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.
