ABSTRACT:
A movable rip fence is adapted for installation on the work table having a planar surface with a pair of rails on opposite sides that are provided with a series of evenly spaced apart holes, and with a cutting tool between the rails that extends above the table surface. The fence comprises an elongated main frame unit that extends between the rails including movable pins at opposite ends for holding the main frame unit generally perpendicular to both rails. A first control device on the main frame which enables the pins to be inserted and retracted into and out from a preselected pair of holes in the rails to first hold the main frame firmly in a predetermined fixed position and thereafter release it for movement to another position. An elongated guide member having an outer planar surface is positioned adjacent and parallel to the main frame and is yieldably attached to it. A second control device is provided for moving the guide member laterally relative to said main frame in a precise manner so as to position its outer planar surface a desired distance from the cutting tool on the rack table. A storage rack is provided at one end of the table to receive and retain the rip fence when it is not in use.
