Abstract:
An assemblage of parts suited for planishing a joint in a generally planar structure including first and second broad surfaces, said assemblage of parts comprising:a planishing hammer including a body, a hammer head, and driving means coupled to said body and to said head, for driving said hammer head in a fore-and-aft direction in a reciprocating manner over a range of travel against said first broad surface of said planar structure;a first magnet;first magnet support means coupled to said body and to said first magnet, for supporting said first magnet at a fore-aft location adjacent said range of travel, which position is laterally displaced from said head relative to said fore-aft direction, whereby the magnetic field of said first magnet penetrates said planar structure when said head is adjacent said first broad surface;a second magnet adapted to be located on said second broad surface of said planar structure, and to be held in place against said second broad surface of said planar structure by said magnetic field of said first magnet; anda backing piece adapted to be held against said second broad surface at said joint of said planar structure, at a location identified by the location of said second magnet.
