As shown, for example in FIGS. 1 to 14, the lockset installation kit includes a door jig (1) configured for attachment to a distal end (2) of a door (3). The door jig (1) clamps to the distal end (2) and is used to guide the boring out of the door handle hole (18), the boring out of the latch bolt hole (15) and the morticing of the latch bolt plate recess (16). As shown for example in FIGS. 27 to 39, the kit also includes a frame jig (29) configured for attachment to a door frame (30). The frame jig (29) is used to guide the boring out of the strike bolt hole (65) and the morticing of the strike plate recess (46). To assist with correct alignment, the kit provides for the door jig (1) to be mechanically coupled to the frame jig (29).

A kit for assisting in the location of holes to be drilled in a door of a thickness between 1 to 1 for the installation of a conventional lock set at a backset of either 2 or 2 with no additional hardware and without damaging the door. A first guide plate defines a first hole saw guide. A second guide plate is attachable to the first guide plate in one of two orientations and defines a second hole saw guide. At least one clamping member is carried by the second guide plate and extends substantially parallel to the first guide plate. Each of the first guide plate and the clamping member define opposing biasing members such that when mounted on a door, the door is centered within the kit.

Example alignment devices for aligning a drill bit with respect to a pilot hole and methods of use are described herein. An example alignment device includes a base having a first surface and a second surface, where the first surface is opposite the second surface. The alignment device also includes an alignment pin extending from the first surface of the base. The alignment device also includes a support extending from the second surface of the base and positioned such that a longitudinal axis of the alignment pin is separated from the support by an offset distance. An inner surface of the support has a radius of curvature along a length of the support. The radius of curvature is substantially equal to the offset distance, and a center of curvature of the support is coaxial with the longitudinal axis of the alignment pin.

A colleted bushing includes a collet and a bushing. The collet has a collet proximal end and a collet bore having collet threads. In addition, the collet has a collet bore taper located adjacent the collet proximal end, and a plurality of collet fingers located adjacent the collet proximal end and configured to be inserted into a workpiece hole of a workpiece. The bushing has a bushing proximal end, a bushing bore, a bushing outer surface, and bushing threads formed along a section of the bushing outer surface. The bushing is configured to be inserted into the collet bore and the bushing threads are configured to engage the collet threads in a manner resulting in movement of the bushing proximal end into contact with the collet bore taper causing the collet fingers to be urged radially outwardly and removably locking the collet within the workpiece hole.

A spindle repair kit including a pair of alignment mandrels positionable in a respective spindle bore of a steering spindle. An alignment rod is operative to retain the mandrels in their respective spindle bores. The kit can also include a first clamp member and a second clamp member, each being positionable between the spindle bores. The kit includes a drill fixture including a drill mounting surface and a bearing fixture including a bearing aperture sized to receive the alignment rod. Fasteners clamp the drill fixture and first clamp member to the first spindle bore and clamp the bearing holder and second clamp member to the second spindle bore. The kit includes an arbor connectable to a drill and a reamer, wherein the arbor is sized to position the reamer in the first spindle bore.

A fastener for fastening a drill jig to overlapping work pieces and clamping the overlapping work pieces for facilitating accurate drilling of the overlapping work pieces including a fastener body and a damper assembly operatively connected to the fastener body. The damper assembly is configured to enable application of a first load to the drill jig, and the fastener body is configured to enable application of a second load to the overlapping work pieces when the fastener fastens the drill jig to the overlapping work pieces. The first load is less than the second load. The first load is sufficient to hold the drill jig to the overlapping work pieces during drilling but without causing significant deformation of the drill jig. The second load is sufficient to reduce the formation of burrs during drilling of a hole through the overlapping working pieces.

A spindle assembly for machining a cast workpiece includes a fixture that provides rotational movement to the workpiece around a fixture axis. A first spindle provides rotational movement to a cutting tool around a first spindle axis and a second spindle provides rotational movement to a second cutting tool around a second spindle axis. The first spindle axis and the second spindle axis are transverse to the fixture axis. The fixture is disposed between the first spindle and the second spindle. The pivotal movement of the fixture provides access to opposite sides of the workpiece to the first spindle and the second spindle enabling the cutting tools to simultaneously cut opposing sides of the workpiece. The first cutting tool and the second cutting tool are replaceable by a third cutting tool and a fourth cutting tool to cut an alternative or different aperture into the workpiece.
