Abstract:
A power saw for selectively cutting a workpiece, the workpiece being positioned relative to the saw for cutting, the power saw comprising:(a) a blade positioned within a plane and having a cutting edge, the cutting edge having a thickness, the blade being movable so that the workpiece is cut as the blade engages the workpiece; (b) a shroud covering a portion of the blade, the shroud having an opening extending therethrough in alignment with the plane of the blade; (c) a housing mounted on the shroud over the opening extending therethrough, the housing bounding a compartment, the compartment being in open communication with the opening on the shroud; (d) a first plate disposed within the compartment of the housing, the first plate having an elongated first slot extending therethrough, the first slot being in alignment with the plane of the blade, the first plate being removable from the housing; (e) a light source positioned within the housing on a side of the first plate opposite the blade, the light source being in alignment with the plane of the blade such that light from the light source passes through the first slot and shines on the blade so as to produce a shadow on the workpiece indicative of where the blade will engage the workpiece; and (f) a second plate having a second slot extending therethrough, the second slot having a width greater than the width of the first slot of the first plate, the second plate being configured to selectively replace the first plate.
