A saw mill guide rail capable of being quickly, easily and accurately aligned to the saw blade, having two intersecting surfaces machined into the head of the rail, each parallel rail head length and extending for the length of the rail, one being vertical and the other being horizontal, to thereby form a line of intersection, such that a straight-edge can be positioned against one or both said planar surfaces at the line of intersection to align the rail in a straight line in either or both the vertical and horizontal plane.
