A positioning device for drilling including a positioning base which is provided with a positioning through hole, and a plurality of clamping assemblies which are provided on the positioning base and circumferentially spaced round a central axis a, as center, of the positioning through hole. Each of the clamping assemblies includes an abutting part having an adjustable distance from a central axis of the positioning through hole.

A guide device comprising a hollow body configured to receive a drill bit, the hollow body having a first end; a second end; and a continuous section intermediate the first end and the second end; an opening extending from the first end through the continuous section to the second end; and at least one aperture located on the hollow body intermediate the first and second end of the hollow body.

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.

The invention relates to apparatus for use with a drill bit which is driven to rotate so as to form a hole in a workpiece with which the same is contacted. The apparatus includes guide means with which the drill bit is located and a body with which the workpiece is located and said guide means is movable with respect to the body to cause the drill bit to be advanced along a path which includes an arc portion and, as it is driven to rotate, move into the workpiece to form said hole and allow the hole to be formed in a guided manner with greater accuracy.

There is provided a tool assembly for transferring locations and dimensions of a pattern of holes from a first structure to a second structure. The tool assembly has a transfer plate with a transfer plate pattern of transfer plate holes that include a plurality of oversize holes and two transfer plate index holes. The transfer plate pattern is substantially identical to the pattern in the first structure. The tool assembly has one or more alignment elements installed in the plurality of oversize holes. Each alignment element has a through opening in a coaxial alignment with the oversize hole. The oversize hole allows formation of an alignment variation gap between an exterior of the alignment element and an inner wall of the oversize hole. The tool assembly has one or more holding elements coupled to the transfer plate, each with a central through opening in coaxial alignment with the oversize hole.

The invention relates to a drill hold assembly and a jig including the same. The drill hold assembly includes an engaging means which is selectively moveable between a released position to allow sliding movement of the drill bit with respect thereto and an engaged position in which the drill bit is held in a fixed position or within a predefined range of movement with respect to the engaging block to thereby maintain the drill bit in location with the drill hold assembly. The jig apparatus can be used with a powered drill to rotate the drill bit to provide a driving force to the drill bit and the jig is attached to a support surface and a workpiece is positioned between first and second jaws of the jig and the drill bit is advanced along a guide and introduced into the workpiece to form a hole therein at a predefined angle. The drill bit can then be removed from the hole and the drill bit is held by the drill hold assembly to retain the drill bit in a fixed position with respect to the jig to thereby allow relative movement of the jig apparatus and workpiece whilst the drill bit is retained in position with the jig apparatus.

A jig assembly structured to facilitate attachment of a device to a door including a base having oppositely disposed first and second end segments and an open interior, including first and second open faces. The open interior and the open faces are disposed between the end segments and are cooperatively structured therewith to receive a portion of the door in an operative position therein. A clamp member is movably connected to the first end segment and is least partially disposable into said open interior in clamping relation to the door portion, when in the operative portion. The second end segment is disposed and structured to receive passage therethrough of a tool, from an exterior to and interior of the base, into engaging relation with the door portion disposed in the operative position and into an interior channel of the clamp member.

A pocket hole jig includes a base with a body and a guide holder extending from the body. A clamp assembly is coupled to the base and includes a carriage movable relative to the base and a clamp arm coupled to the carriage. The pocket hole jig also includes a drill guide assembly supported by the guide holder and having a slanted bore configured to receive a drill bit to facilitate drilling a pocket hole in a workpiece. Movement of the carriage relative to the base in a first direction moves the drill guide assembly in a second direction different than the first direction.

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 for transferring a hole pattern from a first component to a second component configured to couple to the first component is provided including a contour plate having a drill plate with a hole pattern substantially identical to the hole pattern of the first component. The position of the drill plate is adjustable to match the hole pattern of the drill plate with the hole pattern of the first component. A slidable fixture configured to support the second component is movable to align the second component with the drill plate such that the hole pattern of the drill plate in relation to the second component matches the hole pattern of the drill plate in relation to the hole pattern of the first component. The hole pattern of the drill plate is used to create a hole pattern in the second component matching the hole pattern of the first component.
