A selective plurality of elongate half-logs, lumber planks which may have imperfect or damaged edges, or a combination of both, are superposed on each other and adhesively joined to form an intermediate assembly, which is then divided by one or more beam-long cuts made perpendicularly to the flat surfaces of the half-logs or planks. The resulting outer sections of the intermediate assembly, substantially mirror-images of each other, are reoriented so that the original outer edges face each other and are positioned so that a selected space remains between them. Various spacing and bracing elements are selectively chosen to connect the two outer sections and thus to form a laminated space-containing wood beam structure, on which surface-covering sheathing or coatings may be applied optionally. |
