|How to Use the Dado Jig|
set up the jig, clamp it to the fence and adjust the front screw (A) so
the distance it protrudes from the jig matches the thickness of the blade
Adjust the back screw (B) so the distance it protrudes matches the desired dado width (½” in Fig. 2a).
Now, lay out the position of the dado on a test piece. Next, lock the rip fence in position (with the jig attached) so the blade aligns with the left layout line when screw A butts against the end of the board (Fig. 1). Then cut the first shoulder.
Next, pivot the swivel arm down and align the second cut by butting the stock against screw B. Then make the second (right) shoulder cut (Fig. 2). You can “fine-tune” the position of the shoulders by adjusting screw B.
Once set, cut the shoulders in your actual workpiece. Then clear the waste between the shoulders.
