ABSTRACT:
An apparatus and method for use with a router guide plate adapted to be secured to the underside of the router, the router guide plate including guide pins, the apparatus including a base platform having top and bottom surfaces, and a guide pin receiving channel mounted on the top surface of the base platform, the channel adapted to receive and guide the guide pins on the router guide plates. Stop blocks are mounted on the base platform adjacent the channel for preventing advance of the router guide plate beyond a predetermined point and an alignment bar is adjustably and removably mounted on the bottom surface of the base platform, the alignment bar being operative to align a piece of wood to be routed relative to the guide pin receiving channel.
The method includes steps of providing the above described apparatus and positioning the base platform adjacent the work face of a work piece such that the bottom surface of the base platform is at least partially overlying the outer surface of the work place. The alignment bar is then adjusted and the guide pins are inserted into the guide pin receiving channel. The router bit is moved into working engagement with the work piece and a routed line is then cut by maintaining the guide pins in the guide pin receiving channel while simultaneous advancing the guide pins along the guide pin receiving channel.
