Abstract: An apparatus for marking and cutting of construction material, wherein the apparatus is adapted for use with a flexible measuring tape. The apparatus utilizes a main body in which a measuring tape is slideably engaged into a retaining slot. A protruding cutting wheel or marking material is set at a desired dimension and guided against a construction material in order to mark or cut the material at a uniform width. Movement of the apparatus along the work piece is easily accomplished since the angled tip or leader of a flexible measuring tape is used as a fence capable of sliding along the work piece with movement of the apparatus.

Abstract: A torque wrench interfaces with a one or more fasteners intended to be tightened or loosened and includes a main housing with two or more preset torque devices which establishes a torque range insuring that the fasteners will not be tightened neither too tight nor too loose. A drive shaft protrudes from the main housing and rotatably drives a drive gear disposed in the main housing in which when rotated, drives the geared torque devices positioned on either side of the drive gear. A helical spring connects two torque pistons and adjustably applies a regulated torque to the driven torque piston in response to movement of the drive torque piston. The torque pistons are in a torque piston casing and are connected by irregular opposing surfaces urged together by the helical spring that allow for the torque pistons to rotate in relation to each other in one rotational direction only and allows the preset torque device to be enabled only when tightening a fastener in the clockwise direction.

Abstract: An improved sanding block is disclosed for receiving and tensioning a continuous or endless sandpaper loop or other abrasive wrap-around belt about the sanding block's periphery. The block has two parts, so shaped that when assembled within an endless abrasive belt, they provide a wedging action, which effectively elongates or expands the periphery of the tool to properly tension the belt.
