ABSTRACT:
A device and associated method for simultaneously cutting a section of laminate to be inlaid and the underlying laminate to receive the inlay, which includes a portable cradle and a router mounted on an adjustable length shaft fitted into the chuck of the router, so that the distance that the cutting blade extends below the base of the portable cradle can be adjusted, the router is held within a rectangular router box split lengthwise on each side, hingedly held together on one side and detachably secured together on the opposite side by spring tension, with the router firmly attached to the top half so that the router cutting blade may be raised from the laminate surface by rotating the top half of the case around the hinge, while the angle of the cutting blade to the laminate is adjusted by means of adjustment screws on each side of the end of the router box opposite to the cutting blade, which rotate the router box up or down around a hinge means, on the bottom of the router box adjacent to the cutting blade, by which it is attached to the base of the portable cradle, the base has a straight edge guide extending beyond the cutting blade to assist straight line cuts of the laminate and a retractable pivot means at the center of the opposite end of the base which enable precise circular cuts of the laminate sheets. This device is utilized to cut the sheets of laminate while they are still mated with double-sided polyester adhesive, with the result that the angle of the cut in the edge of the laminate section to be inlaid precisely matches the angle of the cut in the edge of the laminate section to receive the inlay.
