Abstract: There is disclosed a band saw which can be utilized as a stationary or as a portable tool. The saw is principally designed for portable use with its table in a saw-supporting position, resting on the work, although it can also be utilized in combination with a bench support as a stationary band saw with its table in a work-supporting position. The weight and bulk of the saw are minimal, as necessary for its portable uses, by utilization of a universal adjustment mechanism providing fixed adjustability of the tension and tracking of the saw blade. The saw frame and table are preferably of cast metal to permit simple assembly into a rigid, lightweight tool that is free of frequent maintenance and adjustment. The saw is preferably provided in combination with a bench support for mounting the saw on a work table to provide a stationary band saw.
