DOVETAIL DADO BITS
Any dovetail bit can be used to make dovetail dados (sliding dovetails) as long as the bit does not cut into the
template guide or the base of the jig. The process is identical to that of the standard dovetail dado. Also, you can
use template guides smaller than 3/4" OD which will have the effect of making the dado slot wider than the bit
diameter.
NOTE: Any template guide bushing surface must not extend more than 1/4" from the base.
BOX JOINT BITS
You can make box joints with different diameter router bits for the two workpieces. The process is identical to
making standard box joints except that you will need to change the bit for the second board. Two routers will make
this job easier. However, this two-router method will require two 3/4" OD template guides and two template guide
lock nuts, available from Porter-Cable.
In selecting straight bits for these modified box joints, keep in mind the following:
1. The sum of the diameters of the two straight bits must equal 1".
2, The length of the bit used to cut the first board determines the maximum thickness of the second board.
(Example: if a 3/8" diameter bit used on the first board has a 1/2" long cutter, the maximum thickness of the
second board would be 1/2").

CUTTING THE TAILS
Cut the tail board (drawer side) similar to cutting the rabbeted half-blind dovetail, but remove the spacer and move
the left offset guide directly against the tail board.
NOTE: Support the template with a scrap workpiece thick enough to prevent the cutter from contacting the base.
CUTTING THE PINS
Cut the pin board (drawer front) similar to cutting the rabbeted half-blind dovetail. (If you use the alternate method
of aligning the pin board with secondary board. Make sure the secondary board does not have a rabbet).
NOTE: Ensure that the pin board (drawer front) is thicker than the depth of cut to prevent the cutter from contacting
the base.
FITTING THE JOINT
Fit the joint the same as you would a standard rabbeted half-blind dovetail.
NOTE: If a change in depth-of-cut is required, change it on both bits.
