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.

A machining support configured to reduce spring back of a sheet following a machining operation on the sheet is presented. The machining support comprises a porous material with a plurality of surfaces including a support surface having a contour configured to contact and support the sheet; sealing material covering each of the plurality of surfaces except the support surface; and a vacuum port configured to provide a vacuum to the porous material.

Jigs, fixtures, accessories, and the like for locating, aligning, guiding, engaging, and/or holding a workpiece on a woodworking machinery during a woodworking operation are described, as well as methods of making, modifying, and using jigs, fixtures, and accessories.

The present invention provides a drill bit guide having a handle and a hollow portion wherein the hollow portion has an open end and another end that includes a socket or set screw useful to separate a bolt head from the shank screw portion for use where access to the shank portion is limited or unavailable. A method of use is further included.

A pocket hole jig system is formed of a plurality of jig segments, wherein each jig segment includes a main body having a drill guide and a lock feature that protrudes outward on a first side of the main body and a recess that protrudes inward on a second side of the main body. The system also includes one or more spacers that have a main body of varying width and a lock feature that protrudes outward on a first side of the main body and a recess that protrudes inward on a second side of the main body. Jig segments and spacers may be connected together by inserting the lock feature of a jig segment or spacer into the recess of an adjacent jig segment or spacer. In one arrangement opposing jig segments and/or spacers lock together with a combination of rotational movement as well as sliding movement.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

This invention includes a drill guide (drill depth stop and alignment tool), canting base attachment, and self-aligning dowel jig attachment that allows users to drill holes to prescribed depths into flat work surfaces using various sizes of twist and auger bits while eliminating marring and reducing wood splintering. The canting base attachment allows users to drill holes to prescribed depths and at variable angles into flat surfaces and both large and small cylinders with no free ends using various kinds and sizes of drilling tools without marring. The dowel jig attachment allows users to drill dowel holes to prescribed depths in edges and faces of work pieces that are evenly spaced apart by numerous gauged distances and at infinitely adjustable distances from edges. This invention has drill press-like capabilities and can be used in the field and in shops.

A rotary tube notching apparatus is provided that is capable of operable attachment to a powered rotational drive device. The apparatus comprises a tube support assembly defining an aperture for receiving a tube and having a clamp for securing the tube against movement in relation to the aperture. A shaft assembly is provided for receiving a cutting tool, and a carriage assembly is rotatably mounted to the shaft assembly. The carriage assembly has at least one fastener for securing the shaft assembly in relation to the aperture. The shaft assembly is selectively repositionable in relation to the aperture in an offset dimension defined by linear displacement from a central axis of the aperture, in a yaw dimension defined by a plane extending along a central axis of the aperture, and in a roll dimension defined by a cross-sectional circumference of a tube received within the aperture.
