3. When the shaping operation removes the entire edge of the work (ie
jointing or making a full bead), the shaped edge will not be supported
by the rear fence when both fences are in line, as shown in Fig. 9. In
this case, the workpiece should be advance to the position shown in
Fig. 9 and stopped.
4. The front fence should be advanced to make contact with the work as
shown in Fig. 10. The rear fence will then be in line with the cutting
circle.
Shaping with Collars
Follow these rules when shaping with collars for safest operation and best results :
1. Collars must be smooth and free from all gum or other substances.
2. The edge of the work must be smooth. Any irregularity in the surface,
which rides against the collar, will be duplicated on the shaped
surface.
3. A portion of the work’s edge must remain untouched by the cutter so
that the collar will have sufficient bearing surface. See Fig. 11 for an
example of insufficient bearing surface.
4. Fig. 12 iillustrates sufficient bearing surface.
5. Under no circumstances should a small workpiece be shaped against
the collars as shown in Fig. 13.
