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. 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. The projection on the bottom of the base that fits into a T-slot is bordered by an angled surface that cams against the corner of the T-slot to push the other edge of the projection against the other corner of the T-slot when the base is assembled to the track, to provide a snug fit between the base and the track. The stops are provided with accessory mounting slots. A fixed stop with a half-dovetail surface, lens groove and accessory mounting slots can be mounted to a standard 2×4 that has a mating half-dovetail surface or a flat surface. A miter fixture can be mounted to the accessory slots that has fingers with ends that provide surface support of the mitered end of a workpiece whether the workpiece is supported with its point toward or away from the working plane of the support.

A wood working machine includes a mounting plate assembly for supporting a cutting tool, the assembly including a base plate, first and second intermediate plates on the base plate, and first and second guide plate elements pivotally supported on the intermediate plates, and a cutting tool support plate slidably disposed between the guide plate elements, the guide plate elements being positionable at angular intervals with respect to the intermediate plates, whereby the cutting tool support plate is slidably movable on the base plate between the guide plate elements at a prescribed angle. The mounting plate assembly may include laser sources providing crossed laser beams for positioning the tool bit of the cutting tool near a work piece, and light sources for illuminating the tool bit. A digital sensor may be included for positioning of the work piece.

A circular saw having a machine frame having a table board and a swivel frame arranged underneath the table board, which is swiveled about a swivel axis coplanar with the top side of the table board. The swivel frame accommodates a height adjustable tool bracket carrying at least one cutting tool engaging an associated slot in the table board. The swivel frame in the region of its ends is swivel-suspended on bearing brackets which are mountable on the bottom side of the table board, and are swiveled by an articulated adjusting rod. The tool bracket is height adjusted by an adjusting element which is arranged in driving linkage with an extendable articulated shaft. The adjusting rod and the articulated shaft are operated by cranks mounted on the operating side of the machine frame.
