When the collar is used above the cutter, as shown in Figure 18, the cut cannot be seen. Yet, this
offers some advantage in that the cut is not affected by slight variations in the stock. Also, accidental
lifting will not damage the workpiece. Simply correct the mistake by repeating the operation. The
stacking arrangement is considerably safer because the workpiece covers the entire shaper cutter.

Rub collar between two cutters:
Spindle
Using a rub collar 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 19. Notice that part
of the edge is left uncut. The uncut portion rides on the rub collar. Remember to leave a sufficient
amount of wood to offer a safe bearing surface.
