<p>In general, table saws can be used in a stationary mode only, i.e. the saw blade is fixed in one position. A relatively simple saw assembly which can be used with a ordinary circular saw includes a table with a slot in the top surface thereof for slidably receiving the blade of a saw mounted on a slide beneath the table. The slide is movably mounted on a arcuate track on a carriage for permitting tilting of the blade to make angled cuts. The saw is connected to the slide by a cantilever structure, which permits changing of the amount of blade projecting above the table top, i.e. raising and lowering of the saw to alter the depth of cut. The carriage, is mounted on rails extending longitudinally of the table. A handle is connected to the saw and projects upwardly through the slot to a location above and in front of the blade for manual movement of the carriage, the slide and the saw. The handle is releasably locked in the elevated use position, and can be released and rotated to a position completely beneath the table top. With the handle in the lower position, the carriage is locked in one position on the rails, and the saw is used in the same manner as a conventional table saw.</p> |
