Precision Box Joint Maker
The precision box joint maker doesn't require the need for a story
board. The spacing is exact and constant after one simple width
adjustment is made ( lower right ). The Box Joint Maker allows four size
box joints to be made, 3/4, 5/8, 1/2 and 3/8 by simply inserting the
chosen indexing key ( Middle right ). There is no limit to the length of
the workpiece. The workpiece can be held securely to a workbench
eliminating the need to move it for each cut as a user of a table saw
box joint maker jig must do. Also, the project boards can be doubled
up for faster machining when starting and stopping your pattern
appropriately such as shown in image below.

The width of the router guide slot
is set relative to the size of box
joint wanted as well as the size of
the indexing key inserted under
the adjustment plate.
Fine tuning to make the slot the
exact width of the protrusion is
accomplished by "moving the
guide plate in or out slightly
relative to the initial setting.
