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 the cut.
There are two types of rub collars—solid and ball-bearing.
We recommend using ball bearing collars for ease of use
and better performance.
Rub collars may be used in any of the following posi-
tions:
1. Rub collar below the cutter:
When the rub collar is
placed below the cutter, as illustrated in Figure 38 ,
the progress of the cut can be observed. However,
any unintentional movement may lift the workpiece
into the cutter, damaging your workpiece and
increasing the risk of operator injury. We DO NOT
recommend using the rub collar below the cutter.
2. Rub collar above the cutter:
When the rub collar
is used above the cutter, the cut cannot be seen
(see
Figure 39
). However, the operator is further
protected from the spinning cutter by the workpiece
itself. As well, there is the advantage that the cut-
ting operation will not be affected by variations in
stock thickness, and accidental lifting will not dam-
age the workpiece. Simply correct any variation in
the height of the cut by repeating the operation.
3. Rub collar between two cutters:
Using a rub col-
lar between two cutters has the advantage of per-
forming two cuts at once, or eliminating the need
to change cutters for two different operations (see
Figure 40
). Notice the uncut part of the workpiece
edge rides on the rub collar.
