1 Before attaching the template to the workpiece, trace the outline on the top of the workpiece for reference.
2 Then screw (or carpet tape) the template to the bottom of the workpiece. Note: Workpiece shown is extra long.
3 Adjust the cutting depth of the bit by lowering the carriage and using the workpiece and template as a reference.
Using the Jig _
With the pin router complete, you're ready to start routing. Things couldn't get much easier at this point. Using the jig is a four-step process.
Template - To make use of the guide pin, you'll need a template. For more on this, refer to the box at the bottom of page 22.
With the template in hand, you might be ready to attach it to the bottom of the workpiece and start working. But I found it easier to start by tracing the outline of the template on the top of the workpiece first (Step 1). This makes it easy to see exactly where you're working.
Next, attach the template to the bottom of the workpiece (Step 2). Just remember to position it so it matches the tracing you made on the top of the workpiece. Then screw (or carpet tape) the template in place.
To adjust the router bit for depth of cut, slide the template and work-piece against the guide pin for reference (Step 3). Note: Set depth for no more than VV1 per pass.
At this point, you're ready to rout. So raise the carriage and slip the
template and workpiece over the guide pin. After turning the router on, lower the carriage until it rests on the base (Step 4), then slide the template back and forth in a clockwise direction as you travel around the pin (see box below).

4 After setting the workpiece and template over the pin, turn the router on and lower the bit into the workpiece. Then rout in a clockwise direction (see box at right).

rout in clockwise direction
v THIRD: —
/ come ' ' back to clean up large areas
FIRST: plunge bit into open area
Direction - To
reduce chipout, rout around the template in a clockwise direction as shown. Then clean up any waste in the center of the template with multiple passes. For areas of the template that aren't connected, simply raise the carriage, set the next open area of the template over the guide pin and rout as before.
