Patent ID: 7162809

Claim:
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 cutting, comprising: a guide bar having a straight outer edge configured for guiding a peripheral edge of the saw housing; a gauge device including 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; a hinge pivotally connecting the holder to the guide bar so that the holder can be swung manually from a position in which the beam projector projects a beam of light along a surface of a flat workpiece to a position where the hinge and gauge device are clear of the straight outer edge of the guide bar so that the saw or router can move without obstruction along the straight outer edge of the guide bar; and means for adjusting the spacing between the guide bar and the beam projector.
