ABSTRACT:
This saw buck structure is compact and light in weight. Primarily, it consists of a hollow rectangular frame having four legs stored within it when not in use, and a handle is provided on one of the sides of the frame, so as to easily carry the structure when not in use. A pair of studs receiving nuts and wing nuts are provided, which secures the legs in the confines of the frame when the structure is not in use, and the fasteners also serve to support the frame in horizontal position for use, when the legs are placed in pairs within each end of the frame.
