I
have two sample side pieces. The first step is to rabbet the ends using the very same
dovetail bit at the very same height.
I have started by placing the fence 1/16" in. I will cut one side and
then the other, and then check the fit.
You can use a simple push block like this.
|
I prefer to use the jig
that I developed for the locking miter cuts. It clamps the work piece and gives me a much
smoother rabbet.
|
 |
 |
I think this is proof that
the jig controls the cutting much better and it can handle two boards at a time.
|
After rabbeting both sides
at 1/16", I test fit the tail. It is too big. I visually check to see how much there
is to remove. I do not want to go over and have too small a tail.
I continue to take off 1/16" at a time on both sides. In fact, to make
the perfect tail for my leg, it took one more 1/16" pass, and then I used the micro
adjust control to "nudge" a little more off. When exactly right, I record the
scale and micro-adjust setting.

 |
With the side fitting
smoothly, I can now measure how much of the "haunch" I have to remove.
|
I use the Incra right
angle fixture to hold the pieces for cutting the haunch. Just like in making the rabbets
for the sides, I cut 1/16" at a time and make successive passes until the piece fits
correctly. I then record that setting.

The sides fit well
not too loose and not too tight. This sample leg took about 30 minutes to set up. I
expect that the actual cutting of the four, final legs and sides will take about the same
time. If I follow my "recipe" (the notes), the final desk should have a solid
foundation.
