ABSTRACT:
A composite wood article includes a plurality of four elongated triangular-shaped pieces and opposing pieces are substantially similar in cross-sectional dimensions. They are joined together to form a composite parallelogram in cross-section. One alternative embodiment includes using sector-shaped pieces that have been cut from generally cylindrical logs, while another embodiment includes triangular-shaped pieces cut from readily available rectangular lumber. In the process of manufacturing the composite article, the four triangular-shaped pieces are first machined so they are properly sized and then after the appropriate application of adhesive to the surfaces which will form the connecting joints, the joinder base leg of each triangular-shaped piece is positioned so as to be juxtaposed against the adjacent joinder leg of the next adjacent triangular-shaped piece. Once all four triangular-shaped pieces are positioned properly, the loosely connected composite is then directed into a pressing station where suitable pressure is exerted on the plurality of joints to cure the adhesive. After the joints are cured, the composite article may then be machined to its final dimension.
