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. We recommend using ball bearing collars
and we carry an extensive line that is designed for
use with Grizzly shapers. See our current catalog
or website for listings.
Rub collars may be used in any of the follow-
ing positions:
1. Rub collar below cutter: When rub collar
is placed below cutter, as shown in Figure
36, progress of the cut can be observed.
However, any unintentional movement may
lift workpiece into the cutter, damaging your
work and creating a dangerous situation. We
DO NOT recommend using rub collar in this
position.

2. Above the cutter: When rub collar is used
above cutter, cut cannot be seen (see Figure
37). This offers some advantage—stock is
not affected by slight variations in thick-
ness and accidental lifting will not damage
workpiece. Simply correct any change in
height by repeating operation.

3. Between two cutters: Using a rub col-
lar between two cutters has the distinct
advantage of performing two cuts at once or
eliminating the need to change cutters for two
different operations (see
Figure 38). Notice
that part of the edge is left uncut. The uncut
portion rides on the rub collar.
