ITEMS NEEDED
Box joints are popular for specific projects such as jewelry boxes,
blanket chests, workbenches or storage bins.
Box joints of variable finger widths can be made using an
accessory box joint kit with the variable finger template (Fig. I1)
or the miniature finger template (Fig. I2) on your OMNIJIG ® .
The accessory kit 77245 (Fig. I1) is used with the 16" and 24"
variable finger templates (55161 or 77241). The accessory kit
55165 (Fig. I2) is used with the 16" and 24" mini finger templates
(55166 or 77246).
The following chart shows the maximum board thickness (B) Fig.
I3 and the minimum finger widths (A) that can be created with
the kits:
Minimum finger
width (A)
Standard fingers 1/2"
Mini fingers 5/16"
NOTE: Box joint accessory kits 55165 and 77245 each include
two offset double stops. These stops differ from the double stops
used for other joinery applications, such as through and half-blind
dovetails, although their function remains the same. The offset
double stops for 77245 include a spacer (S) Fig. I1, that is located
either on the front or back of the stop depending on the board's
thickness to be cut. More detail is provided later in this chapter.
MAXIMUM BOARD WIDTH
If cutting box joints on the 16" or 24" variable finger template, the
entire width of the jig can be used.
For the mini finger template, the maximum board width (C) is 10"
for the 16" template and 18" for the 24" template.
NOTE: The fingers used to cut box joints on the miniature finger
template are the same fingers used to cut half-blind dovetails, as
shown in (D) Fig. I2.
OPTIMAL BOARD WIDTH
Because the fingers are adjustable, there is no suggested optimal
board width (C). The template's fingers can be arranged to
produce whatever configuration is required.
