ABSTRACT:
A system for supporting and positioning a portable stone-cutting track saw to make a mitered cut in a piece stone-type material is described. The system includes lightweight support fixtures that clamp to the stone and that are configured to support rails of the portable track saw system at a desired angle, for example, approximately 45°, or at a variety of angles, with respect to the stone. In one preferred embodiment, two end support fixtures clamp on to ends of the stone and are configured to support track saw rails at an angle of 46° with respect to a horizontal surface of the stone. The system may also comprise one or more types of inline support fixtures for supporting a central portion of the rails when the rails are very long or use of end support fixtures is inconvenient, and a depth-stop mechanism for enhancing repeatability of the mitered cuts.
