  • Patent number: 6095024
    Abstract: In order to enable both miters and box joints to be fabricated using the same piece of apparatus, a miter fence is provided with multiple slidable portions or segments which enable a ledge to be projected from a lower edge of one of the fence faces and for a gap, which is consistent with the spacing required between the male pins of a box joint, to be opened up. A tab is provided to enable a work piece to be placed in abutment therewith. This tab can be used as each slot is cut using a dado blade to set the appropriate spacing for the next slot. The ends of the fence are provided with end caps which have a 45.degree. angle. These caps can be removed and switched about so that the fence can be used on either the left and the right hand sides of the saw table.
