A woodworking machine is disclosed having a base, a blade, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating and/or to stop movement of the blade toward the cutting zone.

A woodworking machinery jig and fixture system includes a track which is or may be attached to a fence, a convex-concave curved flip stop and a base which mounts the stop to the track. The stop has a projecting portion which penetrates the plane of the fence so the stop isn't lifted by the point of a mitered board. The stop also has a lower convex surface which faces the work support surface and curves up at both ends. The top leg of the stop is concave toward the fence to allow clearance for a zero-clearance board and make the stop adaptable to different track and fence configurations. The base has opposite sides of different widths bordered by steps on one side and a ramp on the other side so the base can be used in a large range of T-track slot widths. The arm mounting hole of the base is offset from the base mounting so as to provide an offset to accommodate a ¾″ zero clearance board by turning the base a half turn relative to the slot. A two slot track is provided in which one of the slots can mount a sliding measurement tape or a base, and the other slot can also mount a base. In another track, a sidewall flange is provided which can be filed to accurately fit into a miter gauge slot of a cutting tool table.

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. A re-saw guide fitted to the fence extrusion has a convex surface for supporting a workpiece on edge allowing the operator to easily adjust for blade drift. An optional micro-adjuster allows the fence to move accurately in small increments. A router table with holes and slots allows the fence to be used to guide the workpiece in the router table mode and then be used to guide the router or a saw on top of the workpiece.
