A technique for end-grain creation is employed for obtaining rapid and uniform drying of lumber while simultaneously reducing warp. The stability-kerfing responsible for the improved drying of the lumber decreases the edgewise bending strength by less than ten percent, a loss readily recovered due to the ability of stability- kerfing to achieve lower and more uniform moisture contents than those realized in the contemporary drying of lumber. This overall improvement in moisture content greatly increases the edgewise bending strength for stability-kerfed construction lumber by comparison to that for contemporary construction lumber. Its improved moisture condition at the time of entry into the marketing stream also fosters future dimensional stability compared to that for contemporary lumber. The required stability-kerfing is easily accomplished by the specialized implementation of existing saw equipment and associated technology into the contemporary processing lines.
