Abstract
A portable sawmill (20) having a frame (22) adapted to be disposed transversely of a log (24). A pair of horizontally spaced apart wheels (26a,b) are adapted to straddle the log (24). The wheels (26a,b) are rotatably supported by the frame (22) for rotation in a substantially vertical plane. A band saw blade (28) is trained around the wheels (26a,b) and for movement transversely of the log (24). An engine (30) is provided for rotating at least one of the wheels (26a,b) to cause the band saw blade (28) to form a cut in the log (24) as the frame (22) is moved longitudinally along the log (24). An elevating assembly (44) is provided for supporting the frame (22) so as to enable vertical adjustment of the band saw blade (28) relative to a top surface of the log (24). Guide rollers (40) are interconnected through the frame (22) for guiding the frame (22) along the log (24).
