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 log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths. The saws are adjusted in response to the computer solution and the log is positioned by a positioner according to a computer generated reference datum. This results in the log being positioned for cutting to the optimum random lengths. A command signal is sent from the computer to the log sorting system, which tracks the position of the random lengths and allows them to be sorted to the appropriate sort storage bin.

The log positioning and conveying apparatus is used for conveying a log from an upstream end to a downstream end, and for positioning a log according to a predetermined downstream position. The apparatus comprises an open frame and a number of powered conveying rollers arranged therein in a row. These rollers, in addition to being rotatable, are displaceable in two directions relative to the open frame, namely, in a vertical direction for correcting the position of the log vertically relative to the open frame, and in a horizontal direction transversal to the longitudinal axis of the conveying apparatus, for correcting the position of the log transversely relative to the longitudinal axis.
