A portable bandsaw attachment for cutting symmetrical or asymmetrical convex curved sides into a multisided three dimensional workpiece comprising a rotating table that supports the workpiece, a stationary base that supports the rotating table and provides an attachment point for the rotating table, laterally movable guides and backstop arrangement attached to the rotating table for locating and securing the workpiece relative to the bandsaw blade. The attachment can include handles to grip and turn the rotating table, an opening in the stationary base to provide clearance for the bandsaw blade, and means for securely mounting the stationary base to the bandsaw table.

A portable band saw stand comprising a channel with an upper cradle mounted near one end of the channel and arranged to hold a front handle of a portable band saw. A lower bracket can be mounted at the other end of the channel and arranged to hold a rear handle of the portable band saw, wherein the rear handle comprises a band saw trigger. An on-off trigger mechanism is included that can be mounted to the lower bracket and can be operable to provide an on force to said band saw trigger to turn on said portable band saw. A mounting mechanism is included to mount the channel in a substantially vertical orientation. The band saw stand can also comprise a table that is removable mounted to said channel, wherein the table can be removed from the channel and mounted to the portable band saw to serve as cutting work surface.

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 blade guide for a band saw tool includes an adjustment channel mounted to a blade housing. The adjustment channel has a bracket plate with two recesses at an angle to one another. A roller bracket has a ridge that fits into one or the other recess, the roller bracket including rollers to guide the band saw blade. A single screw holds the roller bracket to the bracket plate. The roller bracket may be moved to the other recess to impart a twist to the blade. The blade is used without a twist when the band saw tool is configured for vertical cutting and is used with a twist when the band saw tool is configured for horizontal cutting.

A band saw that is convertible between a vertical cutting position and a horizontal cutting position includes a work table extension that extends from a work table when the band saw is used in the horizontal cutting position. The work table extension is removable from the work table and is attachable to a blade guide when the band saw is used in the vertical cutting position.

A hand-held band saw has a housing having an opening defining a cut zone. A first wheel and a second wheel are supported by the housing. The first and second wheels define a blade support portion configured to support a continuous blade to be driven through the cut zone. A handle extends from the housing, the handle having a grip portion. A blade guard is coupled to the housing and configured to move between open and closed positions with respect to the housing. The blade guard is configured to cover the blade support portion in the closed position. A chip vent is configured to provide an outlet for workpiece debris formed during a cutting operation, and a tire brush is configured to engage at least one of the first or second wheels to remove workpiece debris from the at least one of the first or second wheels.

Disclosed herein is a machine for cutting nozzles of reactor vessels. The machine for cutting nozzles of reactor vessels comprises a cutting unit positioned at an upper surface edge of a reactor vessel having a nozzle and having a saw blade part having different contact areas to cut the nozzle, a drive unit providing the saw blade part with rotary power, and a foreign substance suction unit provided at one end of the cutting unit in contiguity with the saw blade part to suck foreign substances generated when the nozzle is cut by the saw blade part, wherein the foreign substance suction unit sucks the foreign substances by approaching an outer peripheral surface of the nozzle when the saw blade part moves in a cutting direction of the nozzle.

A rope saw for cutting panels to size includes an elongate frame, which includes a support for placing panels to be sawn thereon. Two wheels are attached to the frame for mounting a revolving saw rope, between which extends a longitudinal direction of the frame. An electric motor is attached to the frame for driving one of the two wheels. The electric motor includes a motor shaft, which extends in longitudinal direction of the frame and which is coupled via a flexible shaft to one of the two wheels.
