ABSTRACT:
In order to precisely form joints in the ends of adjoining molding pieces, a power coping machine includes a molding support surface, a cutting tool, and a cutting tool support. The molding support surface stably supports a piece of molding to be coped with the machine. The molding support surface has a forward edge over which an end of the piece of molding can be made to extend for coping thereof. The cutting tool has a longitudinal axis extending generally transversely of the forward edge of the molding support surface. The cutting tool comprises an electric motor having a shaft extending generally parallel to the forward edge for mounting and driving a circular cutting blade in a plane generally perpendicular to the forward edge. The cutting tool support is disposed in spaced relation to the forward edge of the molding support surface for supporting the cutting tool for controlled movement. The cutting tool support facilitates controlled movement of the cutting tool in a direction generally parallel to and perpendicular to the forward edge of the molding support surface. With this arrangement, the circumferential cutting edge of the circular cutting blade can be moved to cope the end of the piece of molding in a precise fashion to produce a well-fitting joint.
