ABSTRACT:
A jig saw accessory is provided that is adaptable to multiple brands of jig saws and mounts to a saw in place of its conventional flat base. The invention is an improved coping foot plate for a reciprocating saw comprising a round or bullet nosed foot plate having a superior, top surface and an inferior, bottom surface opposite the top surface; an proximal end and a distal end opposite the proximal end; two lateral portions, left and right, opposite each other, each lateral portion being the mirror image of the other as the foot plate is bisected medially from proximal end to distal end; and a means for providing a rounded bearing surface plate for a jig saw with blade whereby triple compound cuts can be made into a material in one motion or movement while maintaining plate bearing contact at the point of blade to material cut or penetration. The invention's rounded shape bears upon the stock material being cut while covering and protecting the reciprocating pivot wheel of the saw and allowing counter support to the upstroke force of the blade. The bearing surface is sloped or formed in such a manner as to allow bearing contact of the plate in the vicinity of blade to material penetration in any of 360.degree. while producing triple compound angle cuts in the material. It is especially effective for coping crown moldings, particularly the cope described by a 135.degree. intersection of the molding pieces. It is useful, however, for any application where it is necessary to alter blade bevel, pitch, and direction or line of the cut while cutting.
