Positioning and centering device, system, and method comprises a pointer having a flat-surface portion and able to be chucked in a cutting-bit holder, together with a thickness gauge mounted relative to a template holder cross member having a positioning and centering hole therein, a centering line on an associated workpiece cutting table, an adjustable fence and scale combination, and a guide-bearing shaft collar, wherein the method comprises inserting the pointer into the router chuck, adjusting the template holder, and the router pinned to the template holder, and through a center hole of a template, to align the pointer with the workpiece table centering line, using the thickness gauge to determine a workpiece thickness midpoint, using the fence and scale combination to center the workpiece on the table, and using the locking collar to enable easy re-location of the guide bearing relative to the tapered template on a subsequent workpiece.

A drill guide for a drill bit of a chucked hand-held drill is disclosed. The drill guide includes a mount, a coupler, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the chucked hand-held drill. The coupler extends from the mount and forms a chuck access window aligned with the chuck when the mount is coupled to the non-rotating portion of the chucked hand-held drill thereby allowing a chuck key to interface with the chuck. The telescoping guard extends from the coupler and is configured to telescope into a retracted position from an extended position. The guide foot is coupled to the telescoping guard such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, and the drill bit passes through the guide foot when the telescoping guard is in the retracted position.

A multi-functional router base that includes associated components and various methods of use herein. The router base includes a base plate and an attachment assembly that is operably engaged with the base plate. The router base also includes a first attachment rod and a second attachment rod provided on the attachment assembly, where the first attachment rod and the second attachment rods are adapted to engage a router. The first attachment rod and the second attachment rod of the router base are linearly moveable relative to the base plate. As to the linear movement, the first attachment rod and the second attachment rod are transversely linearly moveable relative to one another and are vertically linearly moveable relative to the base plate based on the configuration of the router being operably engaged with the router base. An edge guiding fence may be operably engageable with the base plate.

A novel drill jig includes an edge alignment guide, a hole-spacing assembly, a second guide, a biasing member, and an actuator. The edge alignment guide is configured to abut an edge of a workpiece to facilitate movement of the workpiece along a first straight line. The hole-spacing assembly includes a protrusion disposed to engage a preexisting hole in a workpiece positioned by the edge alignment guide. The second guide is coupled to the hole-spacing assembly and is configured to facilitate movement of the hole-spacing assembly along a second straight line perpendicular to the first straight line. The first biasing member is coupled to the hole-spacing assembly and is operative to exert a force on the hole-spacing assembly in a direction parallel to the second straight line. An actuator moves the hole-spacing assembly along the second straight line via the first biasing member.

In one example, an on-wing method for in-situ cutting on a wing-to-fuselage attachment includes attaching a first mount plate having a first linear bearing to provide movement in a first linear direction relative to the first mount plate, attaching a second mount plate having a second linear bearing to provide movement in a second linear direction relative to the second mount plate, attaching a tool mounting member to the second linear bearing to move with the second linear bearing, attaching a cutter to the tool mounting member to be adjustable relative to the second linear bearing, adjusting a depth position of a cut to be made on the wing-to-fuselage attachment, adjusting a width position of the cut, and moving the tool along a length direction of the cut to make the cut on the wing-to-fuselage attachment along the length direction at the adjusted depth position and the adjusted width position.

An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

A counterbalance system employs one or more springs to support a large motor drill on an upper horizontal work surface, for example on the tops of drill jigs or bushings. The counterbalance system supports the drill above the work surface where the counterbalance system can slide across the work surface to selectively position the drill over a drill bushing through which a drilling operation is to be performed. A user of the drill supported on the counterbalance system can then push downwardly on the drill to compress the spring and perform a drilling operation. On removal of the downward directed force exerted by the user of the drill, the spring pushes the drill upwardly to disengage the drill from the work surface. The user of the counterbalance system can then slide the counterbalance system and the drill across the top of the work surface.

A hand-held power tool, in particular a router, includes a machine housing and a support device for guiding the hand-held power tool on a workpiece. The support device has a carrier element, in which the machine housing is at least partially received and fastened. A foot plate which allows an insert tool, in particular a milling tool, to pass through and which is designed to bear against a workpiece is fastened to an end flange of the carrier element facing away from the machine housing. An edge guide for guiding the hand-held power tool along an edge of the workpiece is fastenable to the end flange of the carrier element. A groove is formed in the end flange. A fastening portion of a holding arm of the edge guide can be received interlockingly in the groove and can be fastened by means of at least one fastening element.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.
