This jig is basically a "T" square you make yourself. This one will accommodate a 4' dadoe. The first pass puts into the jig the exact groove. When inserting the panel, simply put mark on panel line up with groove, and set bar clamp so that the top bracket touches the right leg to keep it from moving. I've used this type of jig for over 30 years and it's a very fast set-up. It's accurate as all heck. Can do long or short runs. The panel in the picture is 18" x 18". |
