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

An adjustable holding device having a pair of adjustment drill grooves and a transverse exhaust channel. Attached to the base is a vertical support member having guide supports. At least one of the guide supports is horizontally adjustable. Drill guides are removably attached to the guide support for both vertical and horizontal adjustment.

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 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.

Embodiments herein provide drill hole location transfer between remote components. One embodiment is an apparatus for replicating drill holes of a first workpiece on a second workpiece remotely located from the first workpiece. The apparatus includes an interface to receive coordinate data of first alignment pins installed to first template holes of a first drill plate, and a receptacle to receive a second drill plate having second template holes that match a pattern of the first templates holes of the first drill plate. A pin setting device moves a reference member in a plane over the receptacle, and positions the reference member with respect to the second drill plate based on the coordinate data of the first alignment pins, thus indicating locations within the second template holes to position drill bushings for replicating the first holes of the first workpiece on the second workpiece.

A pocket hole jig is provided, including a body with a first end having at least one drill entry port in communication with an internal drilling chamber, and a second, opposite end having a chip flute in communication with the drilling chamber; a distance adjustment base configured for contact with a workpiece and is configured so that said body is linearly slidable relative to said base for adjusting drill depth and drilling position of the workpiece; and a dust collector fitting removably attachable to, and in communication with the chip flute, at least one of the dust collector fitting and the chip flute being configured for accommodating a clamp for securing the jig to the workpiece.

A system for regenerating fastener holes in a replacement tip section of a rotor blade includes a first fixture, a second fixture, and a third fixture positionable adjacent a tip section of the rotor blade. The first fixture is used to verify a position of an opening formed in the spar. The second fixture includes a removable bushing having a drillable opening. The drillable opening is aligned with the at least one opening formed in the spar and defines at least one hole to be formed in the replacement tip section. The third fixture includes a countersink opening. The countersink opening is aligned with the at least one hole to be formed in the replacement tip section and the at least one opening formed in the spar to define a countersink feature to be formed in the at least one hole.

Jigs and fixtures for aligning, guiding, and/or holding a workpiece on woodworking machinery during a woodworking operation are described, as well as methods of making, modifying, and using jigs and fixtures. A clamp-on flip stop assembly is coupleable to a pocket hole jig or a portable pocket hole jig and can function as a flip stop base and a support for other accessories. An adjustable U-shaped stop is securable to the top outside corner of the pocket hole drill guide and can be designed to fit on either side of the drill guide body. A horizontal adjustment screw positions the workpiece boards accurately and consistently for drilling. Two parallel tapered grooves on the outside of the threaded flanges of the U-shaped extrusion can be included to allow accessories to be secured to the jig.

Drilling aid apparatuses and methods for drilling a structure are provided. In one example, a drilling aid apparatus includes a bushing holder portion. The bushing holder portion has a first surface for facing a first structure portion, a second surface on a side opposite the first surface, and an opening formed through the bushing holder portion extending from the first surface to the second surface. The opening is configured to receive a bushing that is sized for guiding a drill bit for drilling into the first structure portion. A first coupling member is coupled to the bushing holder portion and is configured to couple to a second structure portion for supporting the bushing holder portion in a fixed position relative to the first structure portion.
