  • Patent number: 6725754
    Abstract: A workpiece positioning device for precisely positioning a workpiece relative to a power tool or other device. The device includes a stationary base, an elongated locator member carried by the base for limited slideable movement right and left thereof. The locator member having a set of spaced-apart circumferential slots therein. An elongated scale made fast to the base and disposed adjacent to the locator member has a set of axially aligned spaced-apart through-apertures therein for positioning of the scale relative to said locator member. A movable stop having a surface thereon for abutting against a workpiece is disposed adjacent to the locator member for limited slideable movement right and left thereof. The movable stop being incrementally positionable relative to the locator member. The locator member being incrementally positionable relative to the scale. Whereby a workpiece abutting the movable stop will be exactly located in the precise position selected therefor.
