ABSTRACT:
A guide device securable to a hand-held router facilitates the guiding of the router across a thin workpiece so that the rotatable cutting tool of the router severs the workpiece along a prescribed cutting path and so that the prescribed cutting path corresponds with an edge of an object underlying the workpiece. The guide device includes a platen body which moves between the workpiece and the underlying object as the router is moved across the workpiece, and the body includes a lengthy abutment surface positionable in abutting engagement with the edge of the underlying object. When moving the router across the workpiece while maintaining the abutment surface in abutting relationship with the edge of the underlying object, the cutting tool of the router moves in cutting engagement with the workpiece along the prescribed cutting path.
