A guide for use with a powered hand saw for making controlled cuts in a workpiece at an infinite number of angles. The guide includes a pair of parallel spaced rails, a pair of carriages slidably mounted on the rails, and for each carriage, a clamping assembly for clamping the guide onto a workpiece. Each clamping assembly includes an arm having an inner end swingably mounted on the associated carriage. Each carriage also includes disengageable stop-lock mechanism for locking the associated clamping-assembly arm in a preselected angular position relative to the carriage. Provided on each arm is a pointer for pointing at angular position markings on the associated carriage.
