Abstract
Abstract A power saw-supporting and guiding apparatus comprising a parallelogram linkage adapted to be pivotally mounted on a rigid upstanding wall of a miter box and having a plate for supporting a power saw. The support plate is provided with magnets for securing and retaining the power saw in properly oriented position. Vertically adjustable support legs are provided on opposite ends of the parallelogram linkage. A quadrant, having indicia imprinted thereon, is secured to the rigid upstanding wall and is provided with means for securing said parallelogram linkage to said quadrant at the desired angle.
