2. Above the cutter: When the rub collar is
used above the cutter, the cut cannot be
seen (see Figure 47). This offers some
advantage—the stock is not affected by slight
variations in thickness and accidental lifting
will not damage the workpiece. Simply cor-
rect any change in height by repeating the
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 48). Notice
that part of the edge is left uncut. The uncut
portion rides on the rub collar.

Irregular or freehand shaping takes a high degree
of skill and dexterity. The fence assembly is not
used in irregular shaping, so rub collars must be
used. (See Rub Collars on Page 34).
When doing freehand work, a starting pin
must be used. The purpose of the starting pin
is to support the workpiece during the beginning
of the cut. Your shaper is supplied with a starting
pin that can be placed in one of the holes located
in the shaper table. The work should be placed in
the starting position using the starting pin for sup-
port, as shown in Figure 49.

Next, swing the work into the cutter while hold-
ing the workpiece firmly against the starting pin.
After the cut has been started, the work should be
swung away from the starting pin and is support-
ed just by the rub collar, as shown by the broken
line positions shown in Figure 49.
ALWAYS FEED AGAINST THE ROTATION OF
THE CUTTER.
Irregular Shaping
Freehand shaping greatly increases the
chance that the operator may lose control of
the workpiece, which could result in serious
personal injury. Therefore, a starting pin or
support MUST be used to start an irregular
shaping operation.
