W1674 Owner's Manual (Mfg. After 9/05)
With some irregular shaping operations, the locations of
the starting pin holes are not in the best positions. When
this is the case, clamp a wood scrap to the shaper table,
as shown in Figure 58, then use the wood as the starting
support.
Pattern Shaping
The use of templates allows identical parts to be shaped
with speed and accuracy. Shaping a pattern begins by
attaching a pre-fabricated template to the workpiece.
The edge of the template rides against a rub collar on the
spindle as the matching profile is cut on the workpiece, as
illustrated in Figure 59.
Follow these rules when making a template:
•
Design the template so that the cutting occurs
underneath the rub collar and that screws or clamps
will not come into contact with the cutter during
operation.
•
Install handles on top of the template so that you
can comfortably and safely control the operation.
•
Make sure the template material will work smoothly
with the starting pin/support and the rub collar.
•
Consider the rub collar diameter when designing the
template.
•
Never start the cut on a corner or sharp point of the
template.

support (shown without the safety clamp
To avoid possible injury from flying
debris, design jigs and fixtures so that
screws and clamps DO NOT contact the
cutter during operation. Make sure the
workpiece is held securely to the jig
and the jig is stable on the shaper table.
A sudden loss of control could lead to
serious personal injury.
