Abstract: A borescope having a miniature camera concealable within a hand-held casing, includes a casing, which is preferably a clam shell casing and is able to be held in a single hand of a user, along with a device for opening the casing. A flexible probe has a first end mounted in the casing and a second end being a distal end that is able to be moved from inside the casing to outside the casing with the miniature camera being located at, or proximate to, the distal end of the flexible probe for viewing structures outside of the casing after the casing is opened. The flexible probe with the miniature camera is able to be completely concealed within the casing when not in use. A display is located on a surface of the casing for viewing by the user that which is being seen by the miniature camera.

Abstract: A digital T-bevel has a blade with a slot along a part of its length and a handle having an end that is mounted both to move along the length of the slot and to pivot with respect to the blade longitudinal axis. The handle also includes an encoder to measure the angle of the handle relative to the blade longitudinal axis and the necessary electronic circuitry to convert the measured angle into digital form to drive a display to visually display the numerical value of the measured angle.

Abstract: A jig for cutting plugs for pocket holes from a workpiece has a base leg, from which transversely extend guide and clamp legs. One or more guide channels extend through the guide leg at an angle to an interior face of the guide leg to guide the sleeve of a rotating cutter bit that has a cutting edge at its end and a removed section forming a cutting blade. A clamp extends from the clamp leg to engage one face of a workpiece whose end is mounted on a raised ledge on the base leg and holds the workpiece opposing face against the guide leg interior surface as the sleeve end cutting edge and blade advances into and cuts entirely through the workpiece to cut the plug. A collar on the cutting bit shaft engages the guide leg to prevent the sleeve end cutting edge from contacting the base leg. The jig also can be used for making pocket holes by using the appropriate drill bit.

Abstract: A combination mortise and tenon jig has a body including a platform having an open section with first and second clamp legs on opposite sides for holding a workpiece therebetween with the workpiece part in which a mortise or tenon is to be cut facing toward the open section. A plurality of adjustable members extend from the first clamp leg to engage a workpiece face and the second clamp leg is movable relative to the open section with the extending members and the second clamp leg holding the workpiece at a selected position in the open section. A pair of guide arms pivotally mounted below the platform swing across the platform open section to engage the workpiece part and make it parallel to the platform and a template having a cutout pattern of one of a mortise or tenon overlies the platform open section to guide a router bit to cut the mortise or tenon in the workpiece end.

Abstract: A fixture for drilling a pocket hole in a working face of workpieces of different thicknesses is a U-shaped member having a guide leg and a clamp leg parallel to each other and joined together at a bottom end of each by a transverse base leg. An angled guide channel is in the guide leg that has an entrance for a drill bit on an exterior part of the guide leg and an exit on an interior face which opposes the workpiece working face. A plurality of horizontal elongated ribs are spaced vertically apart on the guide leg interior below the guide channel exit and there is a shelf having a face on which a second face of the workpiece that is transverse to the working face is to rest and that has an edge with a plurality of horizontal vertically spaced ribs to inter-engage with the ribs on said guide leg. A screw extends outwardly from the shelf to extend through a slot in the guide leg and a nut fastens the screw against the guide leg to hold opposing ribs of the guide leg and shelf inter-engaged.
