An apparatus for guiding a rotary tool along a work piece corner edge formed by the intersection of two orthogonal planar surfaces, has a corner guide formed by two orthogonal planar components and defining a longitudinal axis from back to front. An adjustable tool holder assembly is affixed to the corner guide, includes a tool holder, and is configured to independently adjust a tool holder longitudinal position along the corner guide, a radial position of the tool holder relative to the corner guide, and an angular orientation of the tool holder rotating in a transverse plane orthogonal to the longitudinal axis.

A device for localizing a position on a part includes a support to receive the part, a bushing movably mounted with respect to the support, a removable localization member to be inserted into the bushing, and a blocking device to fix the bushing with respect to the support and to maintain it in position.

A method of making a seal-set for a rotary catheter drive unit containing a motor and a seal-set, an output shaft of the motor being power transmittingly connected to a flexible shaft that is rotatably disposed through the seal-set, the seal-set comprising a bearing and an adjacent seal defining a first and a second concentric bores, respectively, the first bore being slightly larger than a diameter of the shaft so that it rotatably and accurately supports the shaft, the second bore being slightly smaller than the diameter so that it seals around the shaft, the bearing aligning the shaft, so that it is concentric with the second bore, by deflecting the shaft to compensate for eccentricity and misalignment of the second bore relative to the output shaft of the motor.

A pocket hole jig that provides a vacuum attachment for waste debris removal is provided. A pocket hole jig that allows for adjustably positioning a clamp assembly is provided. Methods of operating pocket hole jigs are provided as well.

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.

Disclosed is a core drill guide apparatus for providing a guide for a core drill apparatus to drill into a substrate to form a removable core. The apparatus includes an elongate body with an outer surface and inner space, having an entrance end, an exit end and side walls, a distance between the ends defining a length or height of the elongate body and a width. An passageway extends through the elongate body from entrance to exit end, adapted so that in use, it provides sliding receipt of a fastening system to clamp the apparatus to an outer surface surrounding a first hole in a substrate, allowing the apparatus to abut the outer surface and drill out a core in the substrate underneath and surrounding the first hole. A corresponding guide method and fastening system are also disclosed.

A pocket hole jig with screw sizing system includes a pocket hole jig with a guide block reciprocally carried by a guide holder. The guide block can be raised or lowered relative the guide holder between a range of distances corresponding and calibrated to a horizontal range defined by a workpiece. A scale on a gauge member carried by the guide block is divided into a plurality of zones. An indicator is carried by the guide holder for indicating one of the plurality of zones by the position of the guide block relative the guide holder. Also provided is a series of different size screws, wherein each different size screw of the series corresponds to one of the plurality of zones.

A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

A quick grip pocket hole jig system is presented having a support section having a clamp support, an end stop and a back stop. A clamping assembly is connected to the support section having a clamping rod that extends through the clamp support. A drill guide carrier having a drill guide assembly is connected to the clamping rod on a forward side of the clamp support. A clamp body having a trigger and a release mechanism is connected to the clamping rod on a rearward side of the clamp support. The clamp body is a quick grip clamp body that facilitates quick gripping of a workpiece positioned within the support section. The clamping assembly includes a return spring and a release mechanism such that when the release mechanism is actuated the drill guide carrier and the drill guide assembly are automatically moved to a non-clamping position.
