Operational guidelines
Contour Edge Shaping With Collar continued...
If the workpiece is to be shaped all around the perimeter, hold it firmly and push
the work straight into the cutter until the depth of cut is established by the collar
as shown in Fig.36. Continue to feed the work so that the point of contact on the
edge is always 90 degrees to the collar (or directly in line with the cutter edge)
and held firmly against it.
When the workpiece is not contoured all around, start the cut as shown in Fig.9.
With this operation, the workpiece is positioned against the starter pin and the
end swung into place to start the cut. When the cut has begun and the
workpiece firmly against the collar, swing the stock away from the pin and
proceed with cut.
Warning: Freehand shaping is extremely dangerous. The operator must be
aware at all times of the proximity of his hands to the cutter. Hands must never
come closer than 12" to the cutter without the proper guard or similar safety
device over the cutterhead.
Shaping With Collars
When shaping with collars and the starter pin, always adhere to the following
rules for good work and safe operation:
The collar must have sufficient bearing surface, as shown in Fig.37. Also, the
stock must be fairly heavy in proportion to the cut being made. Under no
circumstances should a short, light workpiece be shaped against the collars, as
in Fig.38.
Note: The edge of the work to be shaped must be smooth. Any irregularity on
the surface which rides against the collar will be duplicated on the molded
surface. Collars must be smooth and free from pitch and other substances.
Position of Collars
Collars may be used above, below or between cutterheads.
1. When the collar is used below the cutter, as shown in Fig.39, the progress of
the cut can be seen throughout the operation. However, any accidental lifting
of the work will gouge the wood and ruin the workpiece.
2. When the collar is used above the cutter, as shown in Fig.40, the cut cannot
be seen. But this method offers an advantage in that the cut is not affected by
slight variations in the thickness of the stock. Also, accidental lifting of the
workpiece will not gouge the workpiece; simply repeat the operation to correct
the mistake.
3. Using the collar between the two cutters has the advantages and
disadvantages of the first two procedures, and is frequently used where both
edges of the work are to be molded, Fig.41.
Note: It is advisable to place the cutter as low as possible on the spindle to
reduce spindle deflection and ensure the best possible finish. Also make sure
that the contacting surfaces of the cutter are smooth, clean and without dents.
