A fence assembly for a table saw includes a primary fence including a first elongated body having a first body first side, a first body second side, a first body top side, and a first body bottom side, and a first height measured between the first body top side and the first body bottom side. A secondary fence is pivotally mounted to the primary fence and pivotable between a deployed position adjacent one of the first body first side or the first body second side, and a stowed position adjacent the other of the first body first side or the first body second side. The secondary fence includes a second elongated body having a second body top side and a second body bottom side, and a second height measured between the second body top side and the second body bottom side. The second height is less than the first height.

An adjustable stop assembly includes a body, a cam, a lock knob, an adjustable rod, and an adjusting knob. The cam is movable into a locked position in which the hook portion is secured to a rail and an unlocked position in which the hook portion is spaced from the rail. The lock knob is configured to interact with the cam. The adjustable rod extends outward from a first side of the body by a first extension amount and a second side of the body by a second extension amount. The adjusting knob is configured to move the adjustable rod to adjust the first extension amount and the second extension amount. A minor sector portion of the adjusting knob is exposed by an opening in the body while a major sector portion of the adjusting knob is covered by the body at a given instance.

The cam is movable into a locked position in which the hook portion is secured to a rail portion of the rail and an unlocked position in which the hook portion is spaced from the rail. The lock knob is configured to interact with the cam to provide a locked state in which the cam is in the locked position and an unlocked state in which the cam is in the unlocked position. The adjustable rod extends outward from a first side of the body by a first extension amount and a second side of the body by a second extension amount. The adjusting knob is configured to move the adjustable rod to adjust the first extension amount and the second extension amount. The adjusting knob is disposed within the body such that a minor sector portion of the adjusting knob is exposed by an opening in the body and a major sector portion of the adjusting knob is covered by the body at a given instance.

A table saw includes a worktable, a left extension frame and a right extension frame respectively slidably mounted at left and right sides of the worktable, a scale unit including a first scale, a second scale and a third scale respectively mounted at the worktable, the left extension frame and the right extension frame, and an indicator unit including a first indicator, a second indicator and a third indicator respectively disposed to aim at the first, second and third scales. Thus, when operating the table saw to cut a workpiece, the user can selectively pull out the left or right extension frame and use the corresponding scale and indicator for quickly judging the correctness of the length to be cut.

A power miter saw is provided with a base including positioning apertures; a table rotatably mounted on the base and including an arm projecting forward; a saw blade and motor mechanism configured to rotate a circular saw blade thereof; a pivotal positioning seat interconnecting two linear guide mechanisms and a support seat at a rear end of the base; a connecting seat interconnecting the linear guide mechanisms to the saw blade and motor mechanism; a locking device; and a positioning device. Knob rotation and button pressing may adjust a rotational position of the table.

Fences for use in table saws are disclosed. One embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned substantially above the tabletop and substantially within the perimeter of the table (including any rail associated with the table). Another embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned along a top surface of the fence and configured so that the fence unclamps from the saw when the actuator, handle or lever is pressed.

A work piece positioning system structured for use with work piece processing equipment. The positioning system comprises a guide rail assembly having at least one guide rail, a measurement pattern positioned on at least a portion of at least one guide rail; and a carriage assembly structured for slidable engagement with at least a portion of the guide rail of the guide rail assembly. The carriage assembly may include a controller configured for wireless data communication with at least one mobile computing device, and a stop block. In different embodiments, the controller can be programmed to receive data communicated from an electronic measurement device; to receive a cut-list including a list of cuts to be made on the work piece processing equipment; and/or to receive data derived from at least one information source associated with at least one dimension of a work piece or at least one attribute of a work piece environment.
