摘要：
A patterning jig for use with a router has a flat template with space-opposed side margins joined by respective front and rear margins. A first opening through the template is spaced inwardly a predetermined distance from one of the side margins and is centered on a line running between those side margins inwardly from the front margin. Also formed in the template is a tongue centered on that line, disposed toward the other of the side margins from the opening and positioned between a pair of open spaces defined through the template. A flat guide projects downwardly from the template parallel to and spaced inwardly of the line from the front margin. Various other accessory components are discussed for expanding upon the facility of usage.
