Record your blade’s actual kerf (including runout) by trimming it into the Setup Gauge. This serves as a template to set up your Dado Stop for a fast, precise dado cut. Best of all—there’s no dado blade required.
Step 1 – Cut a scrap piece of MDF to template on side of your kerf. Without moving the fence, clamp the Setup Gauge to a crosscut sled, contacting the cut piece.
Step 2 – Set blade height to the center of the notch. Remove MDF piece and push Setup Gauge through the cut.
Step 3 – The material trimmed out is an exact replica of the blade’s kerf, including runout. The resulting gap is used toaccount for the kerf when setting Leg 2 of the Dado Stop.
Every blade and saw combination cuts its own unique kerf usually not visible to the naked eye. When it comes to joinery, however, even a few thousands of an inch can make all the difference. The Setup Gauge was designed to solve that very problem. It keeps a physical record of the unique kerf cut by a blade on a specific saw, making quick work of setting up the Dado Stop.
