A saw machine worktable positioning mechanism includes a pivot shaft, an operating member and a first positioning unit so arranged that operating the operating member can drive the first positioning unit to move a positioning member of the first positioning unit relative to the base of the saw machine in one of two reversed directions to lock the worktable of the saw machine to the base or to unlock the worktable from the base.

An automated crosscut saw system utilizing a wood scanning unit to optimize the cuts in a particular piece of wood to remove defects or flaws and a method of use therefor is provided. The automated saw system has the ability to scan and cut a piece of wood simultaneously or in rapid succession without the need for scanning the entire length of the wood prior to cutting. Further, the automated saw system may eliminate the need for a secondary feeder and secondary queue.

An adjustable toe board, an adjustable toe board assembly, kit and sawmill comprising the adjustable toe board are provided. The toe board comprises a baseplate having a first end, an opposed second end, and a rod extending away from the baseplate. The toe board includes a support bar pivotably coupled to the baseplate proximate the first end, spaced apart from the rod, and extending towards the second end, the support bar being configured to support a log. The toe board also includes a ratcheting arm pivotably coupled to the support bar, the ratcheting arm having a plurality of spaced-apart teeth defining notches adapted and positioned to selectively engage with the rod, wherein selective engagement of the teeth with the rod enables pivotal adjustment and releasable locking of the support bar relative to the baseplate during operation.

Foldable miter saws and a folding method of miter saws are disclosed. The foldable miter saws includes a base unit, a worktable, and a cutting unit. The cutting unit includes a support arm pivotally mounted on the worktable, a saw blade, and a driver. The miter saw folding method includes the step of biasing the cutting unit relative to the base unit and the step of rotating the support arm relative to the base unit and the worktable to change the cutting unit from a working position to a folded position, thus reducing the vertical space occupied by the cutting unit and facilitating delivery, storage and package of the foldable miter saws.

A slasher saw system connectable to a source of hydraulic power which requires only three hydraulic lines for power and operation. First, a pressure/power hydraulic line is actuated to turn the saw on and bring the saw down to cut through a stack of timber. Second, the hydraulic pressure/power to bring the saw down is actually provided via back-pressure from a return line returning hydraulic fluid to the source of hydraulic power from the saw. Third, a separate line is used to power the hydraulic cylinder used to raise the saw arm again.

An apparatus and method are provided for forming a kerf in a workpiece, which may be used with a table saw for simultaneously cutting the workpiece to length. A fence-engaging member engages a fence of the table saw to prevent movement of the apparatus relative to the fence. A rotary cutting tool for forming the kerf in the workpiece, is disposed above a work surface supporting the workpiece. A guide member for engaging the workpiece prevents the workpiece from translating in the transverse direction, while permitting the workpiece to translate on the longitudinal direction, on the work surface relative to the rotary cutting tool. A motor-actuated feed roller assists with moving the workpiece into engagement with the rotary cutting tool. An enclosure for the rotary cutting tool defines a dust collection port.
