An apparatus for manufacturing integral wooden angle bars from an integral block of wood which includes a pair of grips for abutting opposite sides of the block of wood, a cradle structure, pivotable away from the pair of grips, for receiving the integral block of wood by gravity feeding and for aligning the integral block of wood so as to be abuttable and thereby fixable by the pair of grips; and a pair of saws for making at least first and second incisions in the block of wood while fixed by the grips and cradle, the first incision extending from a first side of the block of wood to a centerplane thereof, and a second incision extending from a second side of the block of wood opposite the first side, to the centerplane, whereby the planes of the first and second incisions intersect at an angle of substantially 90 DEG . The power saws respectively comprising first and second saw blades for cutting the first and second incisions, the power saws being positioned to cut along the centerplane in tandem, whereby at least two incisions can be made.
