ABSTRACT:
Embodiments of a two-sided or reversible saw guide for cutting I-beams are disclosed. Each embodiment includes a first set of surfaces and a second set of surfaces, with each of the two sets being adapted for use with a different size of I-beam. The first and second sets of surfaces each include a surface or surfaces for bracing the guide in between the edge bars of the I-beam, a surface for supporting the saw, and a surface for guiding the saw as it moves across the I-beam. The first and second sets of surfaces are sized relative to each other so that the guide may be flipped or turned to one orientation for one size of I-beam and then flipped or turned to the second orientation for the second size of I-beam. The preferred guide has the shape of two generally parallel plates connected to each other so that their longitudinal axis are at about 90.degree. to each other, with each plate being sized to fit onto the web section of a different size of I-beam. The guide may be flipped over and turned about 90.degree. to place a plate into the web section of an I-beam, and the two plates cooperate to provide support, guide, and brace surfaces. The guide may optionally include a measuring means, such as a bar-and-stop system that extends out from the guide to measure the distance from an end of the beam to the cutting line.
