  • Patent number: 6601493
    Abstract: A fence system for a band saw. The band saw defines an actual cutting plane and has a table having a table surface defining a desired cutting plane. The fence system comprises a rail member, a base member, a locking assembly, a fence member defining a fence surface, and an adjustment system. The rail member is mounted on the table and defines a rail axis that is substantially perpendicular to the desired cutting plane. The base member is supported by the rail member. The locking assembly selectively locks the base member at a selected position along the rail axis. The adjustment system mounts the fence member to the base member at a selected angle relative to the rail axis. The base member defines a pivot point about which the fence member is rotated by the adjustment system, and the pivot point is adjacent to the rail member.
