Apparatus for guiding a power saw has a guide bar provided with side and end edges. Saw-guiding members near each side edge of the guide bar are parallel to the longitudinal axis of the bar and extend between opposite ends of the bar. There is a longitudinal slot at one end of the bar midway between the saw-guiding members and a cross bar at the opposite end. A clamp may be used to releasably attach the cross bar end of the guide bar to the workpiece while the opposite end is secured by a pivot member entered into the workpiece through the longitudinal slot. The power saw is fitted with a slide connector capable of slidably engaging either one of the saw-guiding members. The arrangement is such that a lengthly workpiece can be cut more than halfway through starting from one end edge whereupon the guide bar can be swung about the pivot to the opposite end edge which allows the cut to be completed with speed and accuracy.
