Box Joints
Box Joints
This simple but effective interlocking joint technique is the easiest of all. You’ll
cut your material two pieces at a time with a backing board, using the “A” cuts
for two of the boards and the “B” cuts for the other two.
Let’s get started.
Install the template
After centering as shown on Pages 8 & 9, select and install the
Box Joint Template. (Refer to Page 16 and Figs. 33 & 33A).
Clamp two pieces of your stock to the Right Angle Fixture with a
backing board as shown in Fig. 63. Begin with a scoring pass,
then advance to the first visible mark on the template in one or two
passes. The first visible mark determines which cut lines to use on
the template for the remainder of the cuts on these two boards. If
the first mark is a “B” cut for example, simply move the INCRA Jig
from “B” cut to “B” cut until you have cut across the full width of
your material. After completing the cuts, flip the boards end for
end and repeat the cuts.
Now clamp the final two boards to the Right Angle Fixture with a
backing board as shown in Fig. 64 and make the alternate series
of cuts remaining on the template on both ends of your boards.

Maintenance
Keeping the saw-toothed racks on your INCRA Jig clean of debris and sawdust is all that is necessary to keep the unit in
top shape. Occasionally remove the clamping knob and blow out the racks. An old toothbrush is a great tool to remove
embedded sawdust and chips. An occasional spray of dry lubricant on the threads of the clamping knob and carriage
bolt will make it easier to clamp and unclamp.
