APPLICATION: EDGE PLANE
The Magic Guide can be used as an Edge Plane to plane the edge of the
work to a smooth finish (see left side of Fig. 6). Plane the rough and
chipped finish of plywood and laminated plastic stock (see right side of
Fig. 6) to form a straight edge before jointing or edge finishing.
Make sure router is disconnected from power
supply while making adjustments and installing or removing bits
and cutters.
Adjustments:
1. Set leading or right (adjustable shoe plate) edge back from the trailing
(left) edge a distance equal to the amount of stock you wish to
remove. (See Fig. 7). It is recommended that when considerable
stock is to be removed that several cuts be made instead of one.
2. Install bit in router and adjust for correct depth (thickness of work).
3. Loosen knurled screws (A,B and C) Fig. 8 and roughly adjust the
guide so cutting edge of bit is in line with trailing edge of guide.
4. Tighten knurled screw (C). While holding a straight edge against the
wall of the trailing edge, adjust position of guide, by turning micro-
screw (D), until cutting edge of bit just touches straight edge. NOTE:
Turning router and guide assembly upside down might make
step 4 easier.
5. Tighten both screws (A and B). The relative position of bit to guide will
then be similar to that shown in Fig. 7.
Making the Cut: Start the cut at the left end of the work with only the
leading edge of the guide flat against the edge of the work. Move router
from left to right. As the cut progresses, the trailing edge will also contact
and ride along on the edge of the work (see Figs. 7 and 8).
Limits: The length of the cutting edge of the bit limits the thickness of
stock to be planed.
Recommendations: We recommend carbide or carbide-tipped bits for
cutting plywood and/or plastics because the resins used in their
fabrication cause burn spots on regular high speed steel bits
