Abstract: The invention is directed to a guide for a power saw or router of the type having a blade and a housing wider than the blade which directly overlies the blade during the cutting operation. The guide includes a guide bar having a straight outer edge configured for guiding a peripheral edge of the saw housing and a gauge device. The gauge device includes an elongated holder and a light beam projector mounted on the holder for projecting a beam of light at an angle relative to a lengthwise axis of the holder. In this respect, the light beam projector is mounted on the holder for projecting a beam of light at a right angle relative to a lengthwise axis of the holder such that the beam of light is parallel to the straight outer edge of the guide bar. The light beam projector is preferably a laser.

Abstract: The invention provides a saw guide for a power saw or router of the type having a blade and a saw housing wider than the blade which directly overlies the blade during cutting. The saw guide includes a guide bar having a straight outer edge for guiding a peripheral guide surface of the saw housing, a gauge bar having a straight outer edge, and a hinge pivotally connecting the gauge bar to the guide bar. The gauge bar can be swung manually from a position in which the gauge bar and guide bar lie parallel on top of a flat workpiece to a position where the hinge and gauge bar are clear of the straight outer edge of the guide bar so that the saw can move without obstruction along the straight outer edge of the guide bar.
