ABSTRACT:
An adjustable back fence for work piece milling on woodworking tools is disclosed having an indexing channel system including at least one channel having an elongated slot with a channel stop at one end. The channel is adjustably attachable to the woodworking tool in a desired configuration with respect to the woodworking tool. The indexing channel system includes at least one indexing spacer of predetermined length that fits within and is retained in the elongated slot of the channel. The adjustable back fence includes a horizontal member attachable to the indexing system through at least one adjustable connection having a connection member extending into the elongated slot of the channel. The connection member interacts with the elongated slot to secure the horizontal member to the channel in a spaced relationship from the channel stop, the spaced relationship determined by the length of the indexing spacer.
