A fixture for drilling a pocket hole in a working face of workpieces of different thicknesses is a U-shaped member having a guide leg and a clamp leg parallel to each other and joined together at a bottom end of each by a transverse base leg. An angled guide channel is in the guide leg that has an entrance for a drill bit on an exterior part of the guide leg and an exit on an interior face which opposes the workpiece working face. A plurality of horizontal elongated ribs are spaced vertically apart on the guide leg interior below the guide channel exit and there is a shelf having a face on which a second face of the workpiece that is transverse to the working face is to rest and that has an edge with a plurality of horizontal vertically spaced ribs to inter-engage with the ribs on said guide leg. A screw extends outwardly from the shelf to extend through a slot in the guide leg and a nut fastens the screw against the guide leg to hold opposing ribs of the guide leg and shelf inter-engaged. Selection of the point of inter-engagement of the ribs sets the height of the shelf support for the workpiece relative to the drill guide channel exit.

A screw-plastic part unit in which the plastic part can be a guide having a tapered bottom end for fitting into a countersink to center the tip end of the screw in the countersink and also can have at least one cut-out portion at its top end to facilitate fracturing of the guide as the screw is threaded into a base member. In one embodiment the screw has a thread between its head and tip end which extends to near the tip end leaving a clear area between the thread end tip end and the part of plastic material molded around the screw clear area in which there can be a circumferential groove or rib into or over which the plastic part is molded to better hold the part to the screw. In another embodiment fins extend into the part hole to hold the screw by an interference type fit.

Screw and plastic part unit

A fixture for drilling pocket holes in workpieces of different thicknesses is formed of a U-shaped member having parallel guide and clamp legs and joined by a transverse base leg. One or more guide channels are formed in the guide leg at an angle to the guide leg that has an external entrance for a drill bit and an exit on the guide leg interior opposite a first surface of the workpiece in which a hole is to be drilled. There is a floor on which a second surface, the narrow edge, of the workpiece that is transverse to the workpiece first surface is to rest that is vertically adjustable relative to the guide channel exit, and an adjustable screw clamp threaded in the clamp leg to engage a third surface of the workpiece opposite the workpiece first surface to hold the workpiece first surface against the interior surface of said guide leg during the time a drill bit is advanced in the guide channel to the workpiece first surface.

A dowel jig for making holes in a member such as a board to accept dowels for projecting toward corresponding holes for receiving the dowels to make butt, end and T type dowel joints for two members. The jig has a base having an internal planar area and at least one hole transversely through the planar area and a transverse leg at each end of the base. A foot is at the outer corner junction of each base end and transverse leg and the lower surfaces of both feet lie in a common plane that is parallel to the base internal planar area so that when the lower surfaces of the feet are placed on the flat upper surface of a member the base hole will be transverse to the flat surface to permit aligned passage of a drill bit to drill a hole in the member transverse to the flat surface. Notches are provided in each of the feet along a line that passes through the hole center to hold a rod in which a hole is drilled. One of the legs also has an internal planar area transverse to the base internal planar area with one or more holes and when the jig is clamped to a member holes can be drilled in an edge of the member using the base holes as guides and in the member upper surface near a member edge using the leg holes as guides.

Dowel jig

A clamp to make a straight edge on a working board has a base with a lower surface to slide on a table saw and a main wall that extends upward from the base. A lower support extends outwardly from the main wall in opposite directions, and two upper supports extend outwardly from the main wall in opposite directions to define channels, wherein a reference board is placed in one channel and the working board in the other channel. A shim arm is pivotally mounted to and extends along the base. A shim support pad is mounted at the free end of the arm and its upper surface is in the same plane as the upper surface of the base. The shim arm swings out from the base so that the pad forms a support on which the working board rests to effectively increase the width of the base.

Jointer clamp

A guide to center a screw or drill bit in the center of a hole of a countersink in a member to engage a piece under the member, the countersink having a downwardly tapered wall from the member to the hole. The guide has a body with a through hole and a tapered part that is to rest on the member tapered wall to align the through hole generally perpendicular to the piece. In a preferred embodiment the guide body tapered part is at an end of the body and the body is of frangible material and holds a screw in the through hole which fractures the body as the screw is threaded into the piece beneath the member. At least one slot is formed in the body along at least a part of its length between its top and bottom ends to facilitate the fracture of the body.

Guides for centering screws and drill bits in countersink holes

A fixture for joining two work pieces by pocket hole joints has a base to be mounted to or movable along a table or other member and a drill guide having one or more angled drill guide channels is mounted to the base to be movable toward and away from the table top on which the work pieces are placed. In one embodiment a toggle type clamp on the base carries the drill guide. In another embodiment the base has an upper arm above the work pieces and the drill guide is mounted on the end of a screw that is threaded into the upper arm. The drill guide is moved by the toggle clamp or screw against the work pieces to hold them clamped to the table and a drill bit is advanced in each angled guide channel into the work pieces to form a pocket joint. A screw is driven through a guide channel into the previously drilled pocket hole to join the work pieces.

Fixture for clamping work pieces for drilling and making pocket hole joints

A U-shaped fixture for drilling pocket holes in a workpiece having a base leg, a guide leg and a clamp leg with the base leg joining the guide leg and clamp leg and there is a guide channel in the guide leg at an angle to the guide leg having an entrance on an exterior surface and an exit on the guide leg interior surface which is to oppose a first surface of the workpiece with a second surface of the workpiece generally transverse to the first surface resting on the interior of the base leg. A threaded adjustable clamp on the clamp leg is movable to engage a third surface of the workpiece that is opposite the first surface to hold the workpiece during the time a drill bit is advanced in the angled guide channel to the workpiece first surface. There is a set of spaced ribs on the interior of the guide leg against which the workpiece first surface rests and the exit opening of the guide channel is in the space between said ribs to permit clearance for ejection of wood chips from the drill bit and the base leg has a recess along an extension line of the guide channel into which the tip of the drill can protrude after it passes through the workpiece.
