ABSTRACT:
The present invention is an adjustable router template suitable for use in forming a stepped recess in a door with the cutting tool of a router. The adjustable template includes a first or lower plate having a lower template opening providing the cutting tool with access to the surface of the door to be cut and a second or upper plate having at least one upper template opening through which the cutting tool is initially inserted to reach the lower opening. The upper opening is more restrictive than the lower opening in limiting the surface area of the door that can be cut by the router. The recess can be cut with a step by adjusting the distance between the first and second plates and adjusting the longitudinal orientation of the upper opening relative to the lower opening.
