A portable sawmill which has an elongate central portion, at least one hinged foldable extension portion, laminated rails, detachable axle/wheel combinations, a tow bar, and adjustable legs. Spacers are received between each rail and the respective support structure for both the central portion and the extension portion, including one spacer a first portion of which is disposed between and attached to each rail and support structure of one of the central portion and the extension portion and a second portion of which is slidingly receivable between each rail and support structure of the other of the central portion and the extension portion as the extension is unfolded for use. A pull cable, when an actuation lever is engaged, effects pivotal movement of a cam to which another pull cable is attached for actuating the engine throttle for cutting wood. At least one other pull cable or other actuation member is attached to the cam to actuate at least one other device upon the actuation of the throttle.

A portable sawmill has an elongate central portion, at least one hinged foldable extension portion, laminated rails, and a tow bar. An elongate tubular axle retaining member is mounted to the base. A pair of torsion axles, to which wheels and tires are attached, are received telescopically in opposite ends respectively of the axle retaining member and detachably attached thereto. A plurality of legs are attached to the base. The legs are height-adjustable to raise the base to a height such that the tires are raised above the ground so that the axles with the attached wheels may be removed.

A method of cutting a workpiece with a band saw is disclosed herein. The method includes rotating, with a band saw machine, a blade about a central longitudinal axis. The method also includes moving, with the band saw machine, the blade and a workpiece relative to the other to form a cut in the workpiece. The method also includes supporting a back edge of the blade at a first position before a lateral entry position of the cut or a second position after a lateral exit position of the cut with a first back support member. The method also includes extending an extension arm of the first back support member to shift the back edge a first distance rectilinearly along the central longitudinal axis toward the workpiece, wherein the shifting is cumulative to rectilinear movement from the moving.

A handheld band saw includes a housing, a motor supported by the housing, a handle coupled to the housing, and a saw blade substantially covered by the housing except a portion of the saw blade extending through a cut zone. The handheld band saw further includes a drive wheel assembly and a shoe coupled to the housing. The shoe extends into the cut zone and is configured to support a workpiece during the cutting operation. The shoe includes an actuator that is coupled for movement with the shoe. The actuator is configured to adjust the shoe to one of a plurality of predefined positions relative to the housing.

A band saw machine includes a working platform, a cutting machine, a vertical displacement element causing the cutting machine to move vertically, a height sensor and a central processor. The working platform includes a reference plane for placing a workpiece. The cutting machine includes a driving wheel, a driven wheel, a band saw wound on the driving wheel and the driven wheel, and a motor that electrically drives the driving wheel. The band saw includes a starting cutting tooth and a processing cutting tooth sequentially arranged. The height sensor detects a starting cutting point of the workpiece farthest from the reference plane. The central processor receives information of a position of the starting cutting point, and controls a displacement speed of the vertical displacement element and a first rotational speed of the motor to cause the starting cutting tooth to first cut at the starting cutting point.
