SAW KERF ALLOWANCE METHOD
An effective way to match the grain in a decorative box is to make the box from one piece of wood and then cut
the lid with a table saw. However, if the dovetails are evenly spaced, they may be unattractive because the saw kerf
removed needed material.
NOTE: For this method, you will need a spacer block equal to the thickness of the saw kerf, typically 1/8" on a
standard saw blade. Also, make the boards wider than the final size of the box by the same thickness.
NOTE: This method is very similar to making standard through-dovetails.

Shade the pins that will be removed (Fig. 35C).
Place the pin board back in the jig.
Install the half-blind template so that its straight edge faces you.
Adjust the pin board so that the marks align with the straight edge of the templet (D) Fig. 35D.
Make the cuts with the router to remove the shaded pins (Fig. 35E).
Remove all excess material.
If you remove a bit more material than necessary, remember that it will be hidden in the joint (E) Fig. 35F.
FITTING THE JOINT
Fit the joint the same as you would the half-blind dovetail.
