Abstract: An improved portable work bench includes a structural body, and a platform disposed on and frictionally contacting the structural body. In addition, the platform includes an override mechanism for allowing horizontal movement of the platform along the structural body. Further, the portable work bench may include a plurality of legs for supporting the structural body. The structural body may be tubular and preferably has a trapezoidal cross-section. Such work bench can be used by disposing the platform on the structural body, so that the platform frictionally contacts the structural body. Then the user can mechanically override the static friction between the platform and the structural body and move the platform horizontally along the structural body.

The battery pack and the remote control unit can be electrically connected to the winch mechanism by a flexible power cable, or the battery pack can be mounted with the winch mechanism and a wireless remote control unit can be used to operate the winch mechanism.

Abstract: A table saw includes a base assembly, a table assembly supported by the base assembly, a saw assembly connected to at least one of the base assembly and the table assembly, the saw assembly having a blade extending through the table assembly, a height adjustment assembly for adjusting the height of the blade, the height adjustment assembly comprising a height adjustment wheel, and bevel adjustment assembly for adjusting the bevel angle of the blade, the bevel adjustment assembly comprising a bevel adjustment wheel. The height and bevel adjustment wheels are disposed at the front of the base assembly. The position of the height and bevel adjustment wheels relative to the front of the base assembly does not change regardless of the blade height and bevel angle.

Abstract: A miter saw having a base assembly, a rotatable table rotatably disposed on the base assembly, and a saw assembly rotatably supported by the table. The miter saw also has a miter lock assembly for locking the rotational position of the saw of the table relative to the base assembly.

Abstract: A saw includes a rotatable cutting blade having a first side, a second side, an outer edge and a front end region, a motor for driving the cutting blade, and a blade guard covering at least a portion of the blade. The saw has an air deflector assembly positioned in proximity to the front edge region of the cutting blade, the air deflector assembly having a first deflector device positioned substantially adjacent to, but spaced apart from, the first side of the rotatable cutting blade, and a second deflector device. The second deflector device is movable between an operating position whereby the second deflector device is positioned substantially adjacent to, but spaced apart from, the second side of the blade, and a non-operating position wherein the second deflector device is spaced apart from the blade by a greater distance than in the operating position.

Abstract: A heat gun has a body with a support mechanism mounted on the handle. The support mechanism includes at least one arm moveably mounted on the handle and which is capable of moving between a first retracted position and a second extended position. The at least one arm, when it is in its extended position, is capable of co-operating with the body to form a platform upon which the heat gun can rest on a work surface while the nozzle is placed remotely from the work surface.

Abstract: A saw assembly has a fixed fence and a moveable fence. The fixed fence has a groove for receiving a tongue of the moveable fence. The tongue of the moveable fence has a first groove and a second groove for controlling a range of movement of the moveable fence relative to the fixed fence.

Abstract: A miter saw has a base assembly, a table assembly rotatably disposed on the base assembly, a support housing connected to the table assembly, and a saw assembly pivotably attached to the support housing. The saw assembly is pivotable downwardly for cutting a workpiece disposed on the table assembly. The saw has a miter lock assembly including a shoe assembly connected to the table housing and movable between a first position not contacting the base assembly and a second position contacting the base assembly. The shoe assembly has a movable shoe for adjusting the angular position of the table assembly relative to the base assembly.

Abstract: A table saw includes a base assembly, a table assembly supported by the base assembly, a saw assembly having a blade extending through the table assembly, and a riving knife assembly connected to the saw assembly. The riving knife assembly has a removable riving knife, and a riving knife locking mechanism for locking the riving knife in the riving knife assembly. A handle is mounted to the base assembly or the table assembly, and is connected to the riving knife locking mechanism for releasing the riving knife without using additional tools.

Abstract: A planer and thicknesser comprising a frame having a passageway that substantially extends through the frame. The planer and thicknesser further comprises an upper table having front and rear sections mounted on the frame, wherein a slot is located between the front and rear sections of the upper table, and a lower table moveably mounted within the passageway. The planer and thicknesser also comprises a cutting drum rotatably mounted within the frame such that a portion of the cutting drum projects upwardly through the slot and a portion of the cutting drum projects downwardly into the passage way. The planer and thicknesser also comprises a cover mounted above the upper table capable of being moved from a first position where it covers a portion of the cutting drum to a second position where it does not cover a portion of the cutting drum.
