Arts and Crafts furniture is often joined with through mortises. The secret to success with that type of joint is avoiding tearout.

Gregory Paolini, a woodworker in Waynesville, N.C., has developed a way to make clean through mortises with a router. In this video, he shows how locate the mortises on the workpiece using a thin plywood template, then using a router fitted with a guide bushing to begin cutting the mortise. He then drills a pilot hole in the middle of the mortise, flips the workpiece over, and uses a bearing-guided bit to finish the cut.
