<p>A splitter (32) is installed behind a circular saw blade (10) to prevent contact between the cut work piece (14) and the upwardly moving rear portion of the saw blade. The splitter includes a plurality of pegs (38) that are installed into splitter location holes (40) drilled into the saw work surface (12) or a zero clearance insert (42). The holes are positioned using a drill guide (36) that is indexed from the side of an actu al kerf (50) rather than from a side of the saw blade. In this manner, variations in kerf width resulting from variations in blade width and vibration of the saw blade are accommodated. Splitters (32a, 32b, 34a, 34b) having incremental amounts of offset between the centerline of the pegs and the planar surface (44, 46) of the splitter may be selected to provide a desired degree of interference and resulting force between the splitter and the work piece. Dual splitters (86, 88) may be used to provide contact with both sides of the kerf. The second splitter may be installed using same dril l guide as used to install the first splitter by adding material to one side of the dri ll guide center rib (52) in a thickness equal to the thickness of the gap between the first splitter and the opposed side of the kerf.</p> |
