A lumber surfacing machine for roughening the surface of at least one face of a length of lumber. The machine utilizes a driven band saw blade which is maintained by a pair of blade guides at an acute angle to the surface of the lumber to be roughened. Additional lumber surfacing blades comprising circular saws may be used in conjunction with the band saw blade. The circular saws are mounted at a small angle with respect to the surface which they are roughening.
