Perimeter Cutting
When a workpiece requires all sides to receive a
shaped profile, it is important to begin with the end
grain sides before cutting the long grain side. As
a cutter approaches the edge of end grain, a small
amount of tear-out will commonly occur. By run-
ning end grain edges first, the tear-out is removed
when the long grain cuts are completed.
Completing cuts in multiple passes (when possi-
ble) rather than one heavy cut, will often produce
cleaner results and can prolong cutter life.
To cut an edge around workpiece perimeter:
1.
Cut workpiece sides (1 & 2) with end grain
first (see Figure 31).
2.
Cut sides with grain (3 & 4) last, or in
sequence, as shown in Figure 31.

Rub Collars
Rub collars are used when shaping curved or
irregular workpieces, such as arched doors or
round table tops, and to limit the depth of your
cut. When using a solid rub collar, do not use
excessive pressure when running your workpiece
through the shaper. Otherwise, a groove may
burn into your pattern and be transferred to your
workpiece. Instead, take several passes, using
lighter pressure against the rub collar.
There are two types of rub collars—solid and
ball-bearing. While the Model G0510ZW comes
with solid rub collars, Grizzly carries an extensive
line of ball bearing rub collars as upgrades. See
Accessories on Page 32.
Use rub collars in any of the following posi-
tions:
1.
Rub collar below cutter: When rub collar
is placed below cutter (see Figure 32), cut
progress can be observed. However, any
unintentional movement may lift workpiece
into cutter, damaging your work and creating
a dangerous situation. We DO NOT recom-
mend using a rub collar in this position.
Not
Recommended!
