A powered sharpening system utilizing a turntable to rotate reversible, interchangeable platters carrying different grades of abrasive for grinding, polishing and lapping woodworking and other edge tools to be sharpened that are secured in a tool holder that contacts a reference surface on a tool rest to facilitate formation of bevels and micro-bevels at desired angles. Use of a platter of a first thickness followed by a thinner platter enables automatic formation of a micro-bevel without any adjustment in the tool holder, tool rest or sharpening technique. The turntable is rotated by an electric motor that also rotates a conventional abrasive wheel or a conventional narrow abrasive belt. The motor is mounted in a base within which a duct is located for coupling to a vacuum system for removing, through ports in the duct, abrasive and metal particles produced in grinding and sharpening. Blades on the underside of the turntable induce airflow through the base to cool the motor and other components.

Bench planes of different sizes having interchangeable components and an adjustable frog providing full blade support with a frog foot that extends through the plane body mouth to terminate co-planer or nearly co-planer with the sole. The rear plane handle or tote is captured between and secured soley to tines projecting from the frog that is adjustably secured to alternative sizes of plane bodies in a manner permitting forward and backward adjustment of the frog position without removing the plane blade. Superior lateral blade position control is provided by set screws in the plane body and contacting blade side edges. Adjustments in the blade cutting angle without modifying the angle at which the blade is held by the frog in the plane may be made by forming a front bevel on the front surface of the blade.

A dowel maker having a first rough-sizing blade attached to a body with a micro-adjust assembly for adjusting blade position and a second finish-cutting blade also attached to a body with a micro-adjust assembly for adjusting blade position. Dowel diameters smaller than the largest diameter the body can accommodate may be produced using interchangeable front insert guides, and interchangeable rear guides are also used for different diameter dowels. A workpiece with a square cross-section end is driven through the dowel maker with a square recess socket driven by an electric hand drill.

A router table sled for use with a router table and a router table fence includes an arm assembly that rides along the fence and a strut assembly that supports the workpiece. The arm assembly includes a slider that slides along an upper edge of the fence and an arm attached to an upper edge of the slide. The arm is usually in a position perpendicular to the slide. The arm is also coupled to a strut assembly that includes a main strut, and two additional struts located beneath the main strut. Each strut includes a longitudinally-centered T-shaped slot formed into top, front, and rear faces. The front faces of each strut lie substantially within the same plane. The two lower struts have opposing edges that are spaced a predetermined distance from each other. When a workpiece is clamped to the faces of the struts, an edge may be placed against the fence. The workpiece may then be moved across the router bit to produce a square cut.

Router table sled

A router baseplate and router table, and a method for accurately mounting the baseplate on a router base and machining table top material to receive the baseplate so that the router may be used suspended upside down in the table top. The router baseplate is a relatively thin plate centered on the router collet that remains attached to the router for free hand use and that is received snugly in a hole in the table top supported by a ledge adjacent to the hole. Two opposed sections of the ledge are omitted so that the router and baseplate can be installed in the table top from the bottom of the table top by tilting the router and baseplate, sliding the baseplate through the openings in the ledge, and then untilting the router and seating the baseplate edge on the ledge. Movement during use in the tabletop is limited by a pin fixed in the baseplate and received in a recess in the ledge.

A clamping apparatus having a fixed post with a pad and a clamping jaw post with a threaded hole, through which a screw with a handle on one end and a pad on the other passes. The clamping apparatus may be used with rails so that on the bottom rail the fixed post is placed within one hole and the clamping jaw post placed within another hole such that a workpiece may be clamped between the two, and additionally a top rail with holes that the other ends of the fixed and clamping jaw post engage with may be added to prevent the workpiece from buckling when clamping pressure is applied by turning the screw.

Panel clamping apparatus

A holder for conventional rectangular cabinet scrapers having a body shaped like an open scroll, pivoting structures within each scroll-like end of the body to grasp a scraper blade along a substantial portion of its entire end, and a centrally located padded pressure plate adjustable with a thumb screw to apply pressure to one face of the cabinet scraper in order to bow it away from the body.

Cabinet scraper holder

A twin screw vise utilizing two threaded vise screw rods that are journaled through flanged nuts fixed to a workbench top or to a rear, fixed bench jaw. The vise screws pass through a movable front jaw and into tee-castings and handles that may be turned to rotate the screws. Sprockets are located on each screw between the tee castings and the front jaw and are coupled by a chain. One of the sprockets is fixed in position on its screw during a calibration procedure. The other sprocket remains free to rotate on its screw, except when a spring loaded pin in the corresponding tee-casting engages a depression in the face of the sprocket, thereby coupling that sprocket to the tee casting and associated screw.

Twin screw vise

A woodworking bench and related fixtures providing an integrated system of bench features, vises, dogs, panel clamps, hold-downs and fixtures that cooperate to provide a highly flexible workpiece holding and clamping apparatus able to accommodate a wide variety of shapes and sizes of workpieces and hold such workpieces in an enormous variety of positions during numerous different operations. Two substantial slabs provide the bench top surface and carry a rectilinear pattern (in rows and files) of round, vertical bench dog holes. The rectilinear pattern of round bench dog holes with specific, equal spacing between holes, and similar holes in the edge of the top, facilitate great flexibility in clamping using conventional round dogs in the bench top holes and corresponding dogs in bench edge-mounted, or end-mounted vises. Such holes also accommodate other clamping, fixing and hold-down fixtures that contribute to flexibility and utility. The two slabs are separated by a tool trough, and optional bench top ends or caps span the ends of the slabs, unify the bench top structure and provide a fixed jaw for an end-mounted twin screw vise. Optional skirts form a deep longitudinal edge for the top and join the ends to form a rectangular frame for the top. Dog holes in the edge of the top permit workpieces to be fixed along the bench edge using the hold-down, two clamping bench dogs, or a fixed dog and either of the clamping dog or the twin screw vise.

A hold-down utilizing a round, interchangeable post having annular barb-like ridges or projections that engage a workbench top through round holes that may be located at substantially any desired positions in the bench top. The post threads into a hold-down body having, on one side of the post, a yoke within which a gooseneck-shaped hold-down arm pivots on a pin received in yoke arms or forks and, on the other side of the post, a screw pressure point and T-shaped slot for receiving the head of a clamping adjustment screw that is journaled through one end of the clamping arm. The other end of the clamping arm terminates in a foot with a rounded pad for exerting pressure against a workpiece.

A hinge drilling jig for use in the '32 mm' or face-frameless system of cabinet construction for locating and drilling the hinge cup and the hinge cup mounting screw holes to be drilled in a cabinet door. A flat bottom drill bit is slideably retained in a jig body for drilling the hinge cup hole, and two thumbscrews locate the jig on the face of the cabinet door relative to its vertical edge. A collar retains the drill bit in the body and a shoulder on the drill bit and annular rings cut on the shank of the drill bit allow measurement of the depth of the hinge cup hole prior to being drilled by the drill bit. A plurality of countersinks on the body locate the position of the hinge mounting screw holes on the face of the cabinet door in predetermined positions. The jig is held in position on the door by a handle or a clamping arm having a clamping screw and a gauge assembly locates the jig on the face of the cabinet door relative to the second edge.
