Abstract: An apparatus is described that is capable of automatically and consecutively processing random lengths of raw part stock boards into finished cabinet, entry door, or window frame rails, without operator intervention. The apparatus processes both cope cuts at the same time while making sure that both the finished rail is the correct length as a function of the length of the raw stock, and that the cope cuts are perpendicular (square) to the long side of the rail. After the cope cuts are made, the machine dimensions the width of the rail and makes a stick cut along one edge of the resulting rail.
