Further, the router head has generally outwardly convex outer surfaces and opposite flat sides intersecting said curved outer surfaces. The router is movable laterally to cut L-shaped grooves in the frame members, which are adapted to have their grooved ends joined by an L-shaped bracket receivable into the grooves to hold the members in L-shaped assembly.
