<p>A self-aligning quick pick-off rip fence for use in a table saw is disclosed. The rip fence holds a workpiece relative to a rotatable saw blade extending through an upper surface of the table saw for longitudinal or rip cutting along the length of the workpiece. The rip fence includes a fence head slidably mounted to a front rail that is attached to the table saw. A fence channel is mounted to the fence head at a first end and extends across the upper surface of the table saw in generally parallel alignment with a plane extending through a rotatable saw blade and terminates in a second end. A self-aligning bearing is attached to the second end of the fence channel and is slidably mounted relative to a rear rail attached to the table saw. A handle assembly is mounted to the first end of the fence channel and is interconnected to the self-aligning bearing for engaging and disengaging same in locked and unlocked relationship to the rear rail. When locked to the rear rail, the self-aligning bearing causes the fence channel to be aligned in substantially squared position relative to the front rail, and when unlocked from the rear rail, enables the entire fence head and channel to be removed from the table saw. The self-aligning quick pick-off rip fence further includes both parallel and incremental adjustment structure for adjusting the fence in parallel relationship to the plane extending through the saw blade as well as precise incremental adjustment of the fence channel relative to the saw blade.</p> |
