USING THE WOODWORKING SUB-BASE
WITH HANDLES
The woodworking sub-base with handles is convenient when
routing 4 in. (101.6 mm), 5 in. (127 mm), or 6 in. (152.4 mm)
circular grooves. It can also be used when routing grooves
parallel to the edge of the workpiece.
The handles allow you to grasp and hold the trimmer with
two hands, similar to grasping and holding a router.
ROUTING GROOVES IN A CIRCLE
See Figure 12.
n There are three holes marked R2", R2-1/2", and R3" on
the sub-base. Each number represents a radius and may
be used when cutting circular grooves that are 4 in. (101.6
mm), 5 in. (127 mm) or 6 in. (152.4 mm) in diameter.
n Select the radius for the desired circle, place a finish-
ing nail through the hole and securely tack it into the
workpiece. This will create a pivot axis for that size ra-
dius.
n Rout a circular groove in a clockwise direction only. See
the arrow in figure 12.
