Abstract: A blade clamp assembly for retaining a rotary blade on the arbor of a rotary tool includes a blade washer for engaging the blade to hold the blade on the arbor and a clamp assembly threaded into the arbor to clamp the blade washer against the blade. The clamp assembly includes a planetary gear system for transmitting torque applied to the clamp assembly to the blade washer, wherein the planetary gear system multiplies the torque transmitted to the blade washer so that the torque transmitted to the blade washer is greater than the torque applied to the clamp assembly.
Abstract: A laser level includes a housing, a pendulum pivotably mounted to the housing and a laser diode assembly disposed on the pendulum. A gimbal assembly is employed for pivotably mounting the pendulum to the housing. The gimbal assembly includes a frame connected to the housing, a first pair of bearings disposed on the frame, an axle extending through the first pair of bearings, a body disposed on the axle and pivotably supporting the pendulum, and a second pair of bearings disposed between the body and the pendulum. The first pair of bearings is disposed on one side of the second pair of bearings.

Abstract: A quick-pin blade tensioning device for a band saw comprises a sliding tension bracket coupled with an upper arm of the band saw. The sliding tension bracket engages an upper band wheel which has a band saw blade coupled to it. A lifting shoe, slidably disposed within the upper arm, imparts movement to the sliding tension bracket. A pin moves the lifting shoe through rotational movement of the pin imparted by a coupling with a tension crank. The tension crank, disposed within the upper arm, has rotational movement imparted to it through a coupling with a tension handle enabled with multiple positions.
Abstract: A work light for a power tool. In an exemplary embodiment, the work light includes a generally cylindrical housing constructed for receiving a light source. The housing includes a pin generally transverse to the housing and unitary with such housing. Further, an electrical coupling is configured to provide electricity to the light source from a power tool electrical source and is integrated with the electrical source. Additionally, a bracket including a flange with a plurality of apertures for receiving a series of fasteners for mounting the bracket to an external surface of the power tool is included. The bracket defines a recessed structure for receiving the pin and includes a pair of recesses spaced apart to retain a first end of the pin and a second end of the pin. The pin included within the housing permits linear positioning of the housing along an axis generally perpendicular to the pin.
Abstract: The present invention generally relates to the field of woodworking tools and particularly to an indexing assembly for a lathe. An aspect of the present invention is directed to a lathe, including a frame; a bed coupled with the frame; a head stock configured for mechanically engaging a first end of a workpiece, the head stock being coupled with the bed; and a tail stock, including a housing, the housing including a fine adjustment assembly for mechanically engaging with a second end of the workpiece, wherein the tail stock is adjustably and slidably coupled with the bed via an indexing assembly, the indexing assembly configured to provide the lathe with positive locking capabilities.
