APPLICATION: CIRCLE GUIDE

Make sure router is disconnected from power supply while making adjustments and installing or removing bits and cutters.
Adjustments:
1.If you have been using your Magic Guide as an Edge Guide, Edge Plane, or Radius Guide, remove the base plate (see plate at right of Fig. 1) by removing the wing nut, flat washer and screw that attach it to the top plate.
2.If you have been using your Magic Guide as a Groove Guide, remove the groove guide bar.
3.Attach the fulcrum pin (see extreme right of Fig. 1) to the bottom of the top plate with the small flat head screw – the same screw used to attach the groove guide bar. It may be attached at any one of the three holes that are countersunk to receive the small screw.
4.Select the bit or cutter to give the desired contour of cut and install it in your router. Adjust for depth of cut.
5.Adjustments for distance of cutter or bit from fulcrum pin are made the same as outlined in steps 6 through 9 under ADJUSTMENTS FOR THE EDGE GUIDE (see page 4).
Making the Cut: First select the location of the center of the circle. Then drill a ¼" hole at this point to receive the fulcrum pin. The hole should be deep enough (approx. 17/32") so the Top Plate will rest flat on the work. Insert the fulcrum pin in the hole and rout the circle in a clockwise direction (see Fig. 16). In the segmented design, you’ll notice tiny nail holes just outside the large rim (see Fig. 17). These were located 90° apart and nails used in place of the fulcrum pin to pivot the router for the four arcs within the large circle.
