Abstract
A process for making composite lumber products from generally cylindrical logs includes the steps of cutting a log radially into a plurality of first sector-shaped pieces and then cutting from the sector-shaped pieces at least two members where the cutting plane is substantially perpendicular to one of the radial faces of the sector-shaped pieces. Then one resulting smaller sector-shaped piece is reversed with respect to a resulting quadrilaterally-shaped piece and the two pieces having a substantially similar width dimension are adhesively bonded together. The composite members thusly formed are then machined into a desired shape or additional joining steps can be performed to increase dimensional size. Thus from a cylindrical log composite lumber is produced resulting in improved lumber yield.
