FITTING THE JOINT
Fitting the joint is the same as fitting the standard dovetail. HINT: Use pieces of scrap wood the same thickness and
species of wood to make test pin boards until the template is adjusted for a perfect fit.
INLAYED JOINTS
The 4200 series dovetail jigs will allow you to make joints with inlays of different colored wood for a very unique
look.
SETUP
Select two sets of router bit combinations from the table for “Through Dovetail Router Bit Combinations" in the
section "TABLES OF COMMONLY AVAILABLE ROUTER BIT SIZES". Use the following table to determine the
thickness of the inlay line
INLAYED THROUGH DOVETAIL
The inlayed through dovetail is produced by utilizing 2
through dovetails, one on top of the other.

Use the set with the bigger dovetail bit for the first joint. Make sure that the length of the cutter on the bit is at least
the thickness of the pin board plus the thickness of the inlay line. At the same time, make sure that the length of the
cutter on the straight bit is at least the thickness of the tail board.
Use the set with the smaller dovetail bit for the second joint. Make sure that the length of the cutter is at least the
thickness of the pin board. At the same time, make sure that the length of the cutter on the straight bit is at least
the thickness of the tail board plus the thickness of the inlay line.
Plane the inlay board the same thickness as the thickness of the pin board plus the thickness of the inlay line from
the table above.

MAKE THE FIRST JOINT
Make the first joint the same way that you would make a standard through dovetail (Fig. 68A).
If the jig is set up to make through dovetails with the tails and pins slightly protruding or recessed, use the alternate
method of setting the router bit depth found in the section on “MISCELLANEOUS TECHNIQUES”.
Glue the joint together and let it dry.
