ABSTRACT:
Small-diameter logs are longitudinally bisected and trimmed to form a flattened surface parallel and opposite the diametric surface formed by the bisection. All longitudinal surfaces of logs, half-logs and planks not visible in the final product are subjected to an overall pattern of cuts or perforations to relieve uneven wood fiber tension, the two half logs are adhesively joined at their trimmed flattened surfaces, the patterned cuts may be filled with adhesive; vertical piles of at least three planks are treated similarly. After adhesive has set a second longitudinal bisection is made through the half-log or plank-pile assembly, resulting in two asymmetric structural units, which are piled in a tight stack to discourage warping or twisting as the stack is subjected to air- or kiln-drying. The dried structural units may be then assembled into rectangular beams or a plurality of them may be aligned parallelly into uniform planar arrays for use as paneling, siding, fencing, flooring or decking; tongue-and-grooved laminates of structural units are also provided for assembling strong weather-resistant structures.
