Rub collar above cutter:
When rub collar is
used above cutter, cut cannot be seen (see
Figure 53). This offers some advantage—
stock is not affected by slight variations
in thickness and accidental lifting will not
damage workpiece. Simply correct any
change in height by repeating operation.

Rub collar between two cutters:
Using a rub
collar 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 54).
Notice that part of the edge is left uncut. The
uncut portion rides on the rub collar.

Using 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. We recommend using ball bearing
collars and our exclusive dealer, Grizzly
Industrial, Inc., carries an extensive line that is
designed for use with South Bend shapers. See
Grizzly's current catalog or website for listings.
Rub collars may be used in any of the
following positions:
1.
Rub collar below cutter:
When rub collar is
placed below cutter, as shown in Figure
52, 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.
