Abstract: A device for guiding and gauging a hand-held power saw during crosscut operations on a workpiece. The device is comprised of a guide section and a gauge section interconnected by means of a length of wood strapping. The guide section has a sheath-like structure mounted on a rectangular plate with an upwardly directed forward flange and a downwardly directed side flange. The forward end of the wood strapping terminates in the guide's sheath-like structure. The forward flange guides the power saw across the front of the device. The side flange positions the device on the workpiece. The gauge section also has a sheath-like structure mounted on a square metal plate with a downwardly directed user side flange and a downwardly directed rear flange. The wood strapping passes through the gauge's sheath-like structure and is fixedly attached thereto. The flanges hold the device in position on and at one end of the workpiece.
