Abstract: The device includes a bed plate which can be placed on the table of a table saw and held against the rip fence and onto the table top by a block clamped to the rip fence which allows the bed to be moved fore-and-aft upon the table top parallel to the saw balde. A live center and a dead center are provided to hold a work piece therebetween parallel to the saw blade. In one aspect of the invention the work piece can be indexed and engage the saw blade to cut three or more equidistant lengthwise facets thereon. In another aspect these facets can be tapered end to end or from the center to each end by shifting the tail stock towards the blade or by first shifting the tail stock and then the head stock. In a still further aspect, the head stock includes means to rotate the work piece by a source of power so that a tapered cylindrical shape may be cut or dowels may be formed.
