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.
There are two types of rub collars—solid and ball-
bearing. While the Model G0510Z comes with
solid rub collars, we carry an extensive line of ball
bearing rub collars as upgrades. See
Section
5: Accessories
on
Page 27
, the current Grizzly
catalog, or www.grizzly.com for listings.
Rub collars may be used in any of the follow-
ing positions:
1. Rub collar below the cutter:
When the rub
collar is placed below the cutter (see
Figure
26
),
the progress of the cut can be observed.
However, any unintentional movement may
lift the workpiece into the cutter, damaging
your work and creating a dangerous situa-
tion.
We DO NOT recommend using the rub
collar in this position.

2.
Above the cutter:
When the rub collar is
used above the cutter, the cut cannot be
seen (see
Figure 27
). This offers some
advantage—the stock is not affected by
slight variations in thickness and accidental
lifting will not damage the workpiece. Simply
correct any change in height by repeating the
operation.
3. Between two cutters:
Using a rub collar
between two cutters has the distinct advan-
tage of performing two cuts at once or elimi-
nating the need to change cutters for two
different operations (see
Figure 28
)
.
Notice
that part of the edge is left uncut. The uncut
portion rides on the rub collar.
