An offset router guide assembly for guiding the movement of a router around an outer edge of a structure having corners during rough cutting of a covering material overlying the structure to provide a predetermined overlap beyond the outer edge of the structure includes a base member having an aperture for passage of a router bit, and a guide member attached to the base member by a spacer member extending between the guide member and the base member to provide a gap therebetween. The guide member has a radius greater than the radius of the router bit for offsetting the router bit a predetermined distance from the outer edge of the structure corresponding to such predetermined overlap. The spacer member has a generally triangular cross section and fits entirely within an area between the base plate and guide member bounded by wall portions of the apertures in the base member and spacer member and the intersection of two arcs with the aperture wall portions and with each other. The centers of the arcs are on diametrically opposite sides of the guide member in a plane substantially perpendicular to the normal direction of travel of the guide member with the router, and have radii substantially equal to the sum of the radii of the guide member and router bit.
A guide assembly for guiding the movement of a router around an outer edge of a structure having corners during rough cutting of a covering material overlying the structure to provide a predetermined overlap of the covering material beyond the outer edge of the structure comprising a base member adapted to be affixed to a bottom surface of the router, said base member having an aperture for passage of a router bit through said base member when affixed to the router, and a guide member attached to said base member by a spacer member extending between said guide member and said base member to provide a gap therebetween for receipt of the covering material, said guide member having an arcuate surface with a radius greater than the radius of the router bit for offsetting the router bit a predetermined distance from the outer edge of the structure corresponding to such predetermined overlap, said spacer member being located adjacent a wall portion of said aperture in said base member inwardly of an arc having a center point at an intersection of said arcuate surface of said guide member with a plane passing through the center axis of said arcuate surface and having a radius equal to the sum of the radii of said arcuate surface and the router bit.
A guide assembly for guiding the movement of a router around an outer edge of a structure having corners during rough cutting of a covering material overlying the structure to provide a predetermined overlap of the covering material beyond the outer edge of the structure comprising a base member adapted to be affixed to a bottom surface of the router, said base member having an aperture for passage of a router bit through said base member when affixed to the router, and a guide member attached to said base member by a spacer member extending between said guide member and said base member to provide a gap therebetween for receipt of the covering material, said guide member having an arcuate surface with a radius greater than the radius of said aperture in said base member, said spacer member being located adjacent a wall portion of said aperture, said spacer member having a generally triangular cross section.
A router comprising a base, a motor mounted to said base for driving a router bit, and a guide assembly for guiding the movement of said router around an outer edge of a structure having corners during rough cutting of a covering material overlying the structure to provide a predetermined overlap of the covering material beyond the outer edge of the structure, said guide assembly comprising a base member affixed to a bottom surface of said base of said router, said base member having an aperture through which said router bit extends, and a guide member attached to said base member by a spacer member extending between said guide member and said base member to provide a gap therebetween for receipt of the covering material, said guide member having an arcuate surface with a radius greater than the radius of said router bit for offsetting said router bit a predetermined distance from the outer edge of the structure corresponding to such predetermined overlap, said spacer member being located adjacent said aperture in said base member on a side opposite the normal direction of travel of said guide assembly with said router, said spacer member having a generally triangular cross section.
