Coping saw attachment for spiral cut-off tools

An apparatus for providing a coping machine by attaching thereto a rotating cut-out tool having a rotating cutting bit, comprising:

• a) a top, middle and base plate, each plate having upper and lower surfaces, said lower surface of said top plate is disposed on said upper surface of said middle plate with said top plate overlapping said middle plate said lower surface of said middle plate is disposed on said upper surface of said base plate;
• b) means for attaching the rotating cut-out tool to said upper surface of said top plate whereby the cut-out tool can be removably attached to the top plate, the rotating cutting bit extending through a first aperture in the top plate in order to cut a work piece, said top plate having a second aperture to accommodate a guide pin to engage a template, said first and second apertures passing through said top plate in an overlapping area of said top plate so that said cutting bit and guide pin do not engage said middle plate;
• c) means for guiding movement of said top plate over said middle plate in a direction in which said first and second apertures in said top plate remain in said overlapping area and means for guiding movement of said middle plate over said base plate in a direction at right angles to the direction of movement of said top plate on said middle plate;
• d) means for removably attaching a template to said base plate, said template extending into an area under the overlapping portion of said top plate whereby said guide pin engages said template;
• e) means for removably attaching a work piece to said base plate substantially adjacent said template;
• and,
• f) said guide pin guiding movement of said top plate to permit the rotating cutting bit to cut an identical shape into the work piece.
