摘要： A turntable is provided on which a conventional radial saw is mounted so that the center of the pivotal adjustment of the saw angle is through the straightedge guide at the side of the boardsupporting portion of the turntable. This arrangement provides a maximum length of cut at all angular settings of the saw with all of the cuts starting centrally of the board-supporting table.
