Follow Rest; 4-Jaw Chuck - Grizzly G4002 Owner's Manual

follow Rest

the follow rest is normally used with small diame-
ter stock to prevent the workpiece from "springing"
under pressure from the turning tool. to install the
follow rest:
1. the follow rest is secured to the saddle with
two cap screws. see figure 11.
2. the bearing surfaces on the follow rest
are similar to those on the steady rest, and
should be lubricated to prevent premature
wear.

4-Jaw chuck

the 4-jaw chuck supplied with the g4002/3 is not
mounted to the back plate. Assembly of the back
plate components is also required.
1.
Make note of the reference lines on each of
the 3-jaw chuck studs. thread each of the
4-jaw chuck cam lock studs into the 4-jaw
chuck back plate to the exact same depth
as the 3-jaw studs. screw in the locking cap
screws.

2. Mount the back plate on the spindle.
3. Accurately measure the inside of the back
relief bore on the 4-jaw chuck. this dimen-
sion is critical, ± .001''.
4.
Face the back plate to true it. Make passes
across the face until its entire surface has
been cut.
5.
turn a shoulder into the face
.001" to .002'' larger than the back relief
bore diameter. Chamfer the corner a small
amount.
6.
set the chuck on the back plate aligning the
shoulder with the relief bore. Use a transfer
punch to mark the back plate. if a transfer
punch is not available, a drill bit of the same
size as the mounting holes in the chuck can
be used. lightly tap on the bit, rotate it 90°
and tap it again.
7.
remove the chuck from the back plate and
center punch the marks. drill and tap the
holes for ⁄ ''-16.

8.
set the chuck on the back plate. line up the
mounting holes and thread in the cap screws
supplied. remember that this is a .001" to
.002" press fit. snug up the first cap screw
then alternate to the cap screw across the
chuck. Alternating the tightening process
insures the chuck will go on straight. this
step should be repeated until the back plate
fits snugly against the chuck. if the chuck fits
loosely on the back plate, or is crooked on
the shoulder, it will be necessary to face and
shoulder the back plate again.
