  • Publication number: 20240139831
    Abstract: A pocket hole drill guide having a central base member, the pocket hole drill guide having two fifteen-degree guide channels for applying a pocket hole on a workpiece by way of a drill and drill bit. The pocket hole drill guide has a three-tenths inch diameter drill guide and a three hundred seventy-five thousandths inch diameter guide channel on opposing ends of the pocket hole drill central base member, with the exit holes of the guide channels on the same contact face of the central base member. The guide channels intersect at the fifteen-degree angles, so material can be removed from, and a user can quickly alternate between the two sized guide channels for ease of use and rapid production capacity. A multi-slot extrusion is provided which may be mounted to an L-shaped extrusion bracket, making the use of a miter bar optional and the system itself more portable.

  • Publication number: 20200030891
    Abstract: 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.

  • Patent number: 7930960
    Abstract: A universal machinery fence system includes an L-shaped fence or a box shaped fence and clamp block which clamps to a rail extrusion with a half dovetail on the front on the edge of a table saw, band saw, shaper, router table, mortiser, or other woodworking or metal working machines. A U-shaped front rail is provided for attaching the fence to the cast iron table of a table saw, shaper, or band saw. The band saw fence U-shaped rail is predrilled to fit the table fence mounting holes of the most popular 14? band saws. Optional extruded front rails are also provided for attaching the fence to shop made 0.750? tables such as used on a drill press. Also provided is a fence rail extrusion for mounting the fence on the front and back of the popular 1.125? size router table. An optional extruded front rail which is adjustable in height is also provided for attaching the fence to shop made tables between 0.750? and 1.5? in thickness.

  • Patent number: 7798187
    Abstract: A woodworking machinery jig and fixture system has a stop with a half-dovetail surface and can be provided with one or more T-slots. The half-dovetail surface can be clamped against a half-dovetail surface on the support, or against a flat surface. In one of the stops, the base has multiple through holes, any one of which can be used to mount a flip stop arm so as to vary the height of the arm or use a zero clearance fence.

In one of the stops, the base has multiple through holes, any one of which can be used to mount a flip stop arm so as to vary the height of the arm or use a zero clearance fence. A track for the system has a flange that helps locate the track along the rear corner of a wood fence and also helps secure the track to the wood fence with fasteners through holes that can be drilled in the flange using a drill guide groove formed in the flange. Tension screws are provided in the stop and in the base for eliminating play between the hinge pin, the flip stop and the base. A lens is received in a groove of the stop arm and extends therefrom in position to view a ruler that is mounted on top of the support, facing up.

  • Publication number: 20050279200
    Abstract: A miter gauge with a machined aluminum head that has a stamped aluminum scale secured in a machined slot. The scale has indicia that facilitate reading the scale including color-coded diamonds, arrow heads and longer lines at key positions. The miter gauge is quickly adjustable to 1/100th of a degree using ordinary shop tools such as a feeler gauge or dial caliper. An optional sled is a platform with two pieces of minitrack on each side and a dado in the middle in which the miter gauge can be secured quickly to a bar on the bottom of the sled that slides in the table saw miter gauge. A flip arm stop design with a removable back allows space for a zero clearance board on the front of an L-shaped fence extrusion. A T-shaped fence extrusion with a built-in zero-clearance board has a modified T-slot with an interlocking minitrack which allows the fence to be extended and secured with a standard bolt without the need for machining.
