OPERATION Routing Grooves In A Circle See Figure 12. n There are three holes marked R2", R2-1/2", and R3" on the woodworking sub-base. Each number represents a radius and may be used when cutting circular grooves that are 4 in., 5 in. or 6 in. in diameter. n Select the radius for the desired circle, place a finishing nail through the hole and securely tack it into the workpiece. This will create a pivot axis for that size radius. n Rout a circular groove in a clockwise direction only. Routing Grooves Parallel To An Edge See Figures 13 - 14. You can use the scale provided on the woodworking subbase accessory to cut a straight parallel line up to 1 in. from the edge of the workpiece. n The intersection of the horizontal and vertical lines at the center of the woodworking sub-base accessory indicates the center of the cutter. This is also the center of groove being cut. n For grooves more than 1 in. from the edge of workpiece, align the center of desired groove on the workpiece with the centerline on the woodworking sub-base accessory. Then measure from the centerline on the woodworking sub-base accessory to the guiding portion of the straight guide. Tighten the knob on the straight guide securely. n Using "C" clamps and a board to act as the straight edge, place the cutter at the desired position on the workpiece and make the cut from right to left. NOTE: The board being used as a straight edge must be 1/4 in. thick to prevent contact with the trimmer base. It must also be at least as long as the workpiece in order to be a guide. n The thrust is from the trimmer against the straight edge. n Do not make a cut that is too heavy in one pass. If a deep cut is required, make successive passes at increasing depths with each new pass until you reach the desired groove depth. WARNING: If the desired depth of cut is greater than can be safely cut in one pass, make cuts in two or more passes. Do not remove more than 1/8 in. in a single pass. Excessive depth of cut can result in loss of control and the possibility of serious personal injury. rout groove from right to left R3 R2 1 2 R2 1 3/14/12/4 Fig. 13 TRIM ROUTER USED WITH A BALL-BEARING GUIDED BIT Fig. 14 17
