APPLICATION: CIRCLE GUIDE
The most intricate of circular-shaped (see Fig. 15) cuts can be made with
the Magic Guide. Perhaps you have seen cuts like these on modern
garage door panels or on inlaid coffee or card tables. You, too, can be an
expert when you use the Magic Guide as a 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.
