ABSTRACT:
A high yield technique to convert normally-unusable round logs of balsa or other species of wood whose diameter is less than about 4 inches into large rectangular panels that are contourable.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 stacked to form a dry assembly in which the pieces are separated from each other to define a matrix of intersticial spaces. The pieces in the assembly are then interlaminated in a mold by filling the matrix with an elastomeric plastic solution which, when cured, functions as an adhesive to provide an integrated stock block. The stock block is then divided into panels of the desired thickness, each panel being constituted by an array of round wood tiles joined together by elastomeric hinges, whereby the resultant panel is contourable and may be conformed to a curved surface.
