ASSEMBLY
Identify and verify that you have all the parts listed.
Read the instructions at least once before beginning.
Cut a wood fence approximately 3/4" thick, 1-1/4"
wide and approximately 12" long. Drill two 1/8" pilot holes
in the edge of the wood fence 4-5/8" on center. Mount the
Strike Plate Jig to the wood fence using the 3/16" Washers
(WB001) and 3/4" Screws (STP001). See fig. 1.
Place the 1/4" Spacers (BUSH002) on the 1/2"
Thumb Screws (5503) and screw them in to the two
holes of the Strike Plate Jig shown. The remaining two
holes in the Strike Plate Jig are for storing the thumb
screws & spacers when not needed. See fig. 2.
Cut a 1/4" thick x 6" long spacer to the width required
to position the strike plate in the desired jamb location. Place
it between the spacers and the wood fence to position the
strike plate opening at the proper distance from the edge
of the jamb. The spacer also insures that the wood fence
is square and parallel on the Strike Plate Jig. See fig. 2.
USING THE JIG ON A JAMB WITHOUT A STOP
Mark the strike plate location on the jamb. The Strike
Plate Jig is 1/8" wider (1/16" on each side) then the actual strike
plate opening it cuts. Position the Strike Plate Jig so it's edges
are 1/16" from the strike plate location marks, or make the
strike plate marks 1/8" further apart to correspond to the actual
opening in the Strike Plate Jig. Clamp the Strike Plate Jig to
the jamb using the wood fence and two clamps. See fig. 1.
Install our 8500 Hinge Bit (1/2" diameter with a
5/8" bearing), or a 1/2" bit (13416) and 5/8" bushing
(5030K), in your router. If using the 8500 Hinge Bit,
make sure the bearing rides firmly on the edge of the jig
before attempting any cuts. Since the cutting depth for
locks is shallow (usually 1/8" or less), either a standard
or plunge router will work. Set the cutting depth of
the bit, taking into account the thickness of the jig.
Plunge or tilt the router bit into the approximate center
of the jig opening, moving in a small clockwise circle as you
do so to cut a relief opening. With the router base riding
firmly on the jig, move towards an edge of the jig opening.
Moving clockwise, follow the jig until the outline has been
cut. Make clean up passes to remove any remaining material.
After making the first cut, the wood fence will have a
cut out area that corresponds to the strike plate size. You can
use this cut out area to position the jig on the next parts.
