Norfield STRIKE MASTER MFG 600 Operational Instructions

1. INSTALLATION
A. Attach strike master
Attach the Strike Master to your workbench or tabletop using three (3) flat head fasteners.
#14 flat head wood screws, or ¼" flat head machine screws with nuts and washers on the
bottom side are recommended. Note in Figure B the 2-3/4" dimension from the edge of
the base plate to the edge of the tabletop.
B. Adjust clamp pads
Adjust the clamp pads for jamb thickness. Loosen the two jamb nuts on the threaded
spindle and position the pad for correct clamping pressure on the size jamb you will be
machining.
C. Adjust reveal adjustment knobs
Adjust the reveal adjustment knobs for proper strike plate positioning in the jamb.
1.
Determine the location of the center of the strike pocket in the jamb (usually 11/16" from the edge for
interior jambs and 7/8" from the edge for exterior jambs).
2. Draw a centerline on a jamb 13" to 14" long, corresponding to the center of the strike pocket.
3.
Clamp the jamb in the Strike Master with the strike pocket centerline aligned with the reference lines on the reference
blocks (see Figure A).
4. Set the adjustment knobs so the edge of the jamb contacts the end of the threaded stop bolt and retighten wing nuts.
2. OPERATION AND ADJUSTMENTS
Most strike plates require the use of two templates; one for the pocket and one for the plate itself. Once the jamb has been clamped
into position in the Strike Master, templates can be exchanged to do the required machining without readjustment.
The templates are designed to be used with a plunge router using a ½" diameter bit and a 5/8" outside diameter template guide. One
exception exists however: T-strike plates require the use of a special ½" diameter router bit with a ½" diameter "top" bearing in place
of a template guide.
A. Jamb positioning
Place pencil marks on the face and edge of the jamb at the location of the center of the latch pocket. Align the jamb in the
Strike Master using the reference line on the base plate and clamp it into position. Optional positioning rails with stops
(MFG 100) are available that can be preset for different lock heights.
B. Router bit depth
With a template snapped into position (see Figure A for correct template orientation) adjust the router bit depth for the plate
first. If you are machining for T-strikes and are using the ½" bit with the ½" diameter top bearing, the bearing should be in
contact with the edge of the template. Set the router's turret stop so this depth can be repeated. Set a second plunge depth
equal to the depth required for the pocket.
C. Jamb machining
We suggest that you route for the plate first and then the pocket. If you are machining for a T-strike pocket, the 5/8" diameter
template guide must be installed on the router for pocket machining. On all other plates and pockets (excluding T-shaped
mortises) leave the 5/8" diameter guide in place at all times.
