Pattern Shaping
Sometimes the location of the starting pin holes
will not always be in the safest position. You
can clamp a piece of scrap wood to the shaper
table. The edge of the wood can be used as the
starting support as shown in Figure 52.
The use of patterns (templates) allows identical
parts to be cut with speed and accuracy.
Shaping with a pattern begins by attaching a
prefabricated template to the rough workpiece.
The edge of the template rides against a rub
collar on the spindle as the cutter cuts the
matching profile on the workpiece edge as
shown in Figure 53. You can incorporate extra
features into the template assembly (such as
toggle clamps) to hold the workpiece and hand
grips, or guards for safety and protection.
To make a template, do these steps:
1. UNPLUG THE SHAPER!
2. Make sure that screws or clamps will not
come into contact with the cutter.
3. Design the assembly so that cutting will occur
underneath the workpiece.
4. Make handles for safety and control.
5. Use materials that will move easily across the
table surface and rub collar.
6. Remember to consider the cutter and rub
collar diameter when making the pattern.
7. Install hold-down clamps at three sides of the
pattern assembly or screw the pattern
assembly to the back side of the workpiece.
8. Again, make sure screws will not come into
contact with cutters.
DESIGN jigs and fixtures so screws and clamps
DO NOT contact the cutter and the
workpiece is held securely to the jig. The jig
must be stable on the shaper table. Failure to
do so could result in serious personal injury.
