ABSTRACT:
A high yield technique for converting normally-unusable round logs of balsa or other species of wood whose diameter is less than about 4 inches into large rectangular panels. The raw logs are first peeled to expose the wood and are then cut into round pieces of a desired length. The pieces, after being kiln dried, are assembled into a block, the pieces being coated with a curable adhesive and being subjected to compression in orthogonal directions until the adhesive is cured and the pieces interlaminated to provide an integrated stock block. The stock block is then divided into panels of the desired thickness and grain direction.
