A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.

Ribs for working an aircraft component having an aircraft component surface, fixtures for the same, and methods for the same, are provided herein. The rib includes a rib surface configured to receive the aircraft component and to be in abutting contact with at least a portion of the aircraft component surface. The rib further includes an extension extending away from the rib and configured to couple to a worksurface. Orientation of the rib is configured to be adjustable relative to the worksurface for improving working of the aircraft component. The fixture includes a mount defining an aperture and configured to be coupled to the worksurface and the rib. The method includes providing the fixture including the rib. The method further includes coupling the extension to a worksurface. The method further includes disposing the aircraft component on the rib surface.

Jigs for forming holes for mounting a hinge to a door or frame is provided. The jig includes a main body defining a drilling aperture extending therethrough. The drilling aperture may be bounded by a tapered sidewall. The jig may include alignment cams that include knobs that allow for adjusting the position of the jig relative to the door. A cabinet hole template may be provided. The jig may provide structure for quickly locating a depth stop relative to a drill bit. The jig may include drill bit guides for forming holes for fasteners relative to a main cup hole that may be formed using the jig.

A self-adjusting pocket hole jig system is presented having a base, an upright assembly operably connected to the base, a clamping assembly, operably connected to the upright assembly, a handle operably connected to the clamping assembly, and a drill guide assembly operably connected to the clamping assembly. The drill guide assembly is configured and arranged to move along the upright assembly between an unclamped position and a clamped position in response to movement of the handle. Movement of the handle simultaneously adjusts the height of the drill guide assembly as well as facilitates clamping of the drill guide assembly for workpieces of various thicknesses.

A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

An in-situ square sample acquisition device and method for a bond contact test of a surrounding rock and a shotcrete layer are provided, the device includes a supporting shell, a fixing structure, hollow adjusting bolts and two borehole positioning frames, a guide hole is provided in a middle of the supporting shell, the frames are slidably fit in the guide hole, a plurality of positioning holes are provided in side walls of each of the frames, and the positioning holes in different frames are distributed in a staggered manner, four corners of the supporting shell are connected with four hollow adjusting bolts respectively, one end of each of the hollow adjusting bolts is fixedly provided with an adjusting nut, four fixing lugs are provided in four corners of each frame respectively, and the fixing structure includes four connecting bolts and four nuts.

A guide template having a tool guide for a working tool, for producing a main-side cut-out on a workpiece main-side surface of a workpiece which workpiece has a workpiece secondary-side surface, which is at an angle to the workpiece main-side surface and proceeding from which a secondary-side cut-out extends into the workpiece next to the workpiece main-side surface at a distance therefrom, wherein the guide template includes a main-side stop having a main-side stop surface for making contact with the workpiece main-side surface and includes a secondary-side stop, which has an engagement protrusion for engaging the secondary-side cut-out, wherein a longitudinal axis of the engagement protrusion extends toward the tool guide to an intersection region, in which the main-side cut-out to be produced and the secondary-side cut-out intersect, and is at an angle to a guide longitudinal axis of the tool guide, wherein the guide template includes a depth stop having a depth stop surface for a counter stop assigned to the working tool for limiting the penetration depth of the working tool into the workpiece with respect to the guide longitudinal axis.
