Converted log structural products and method
Converted log structural products are produced from conventionally unusable or marginally useful sections of logs transversely cut into suitable lengths and then cut longitudinally by perpendicular cuts into log parts of either right-angled sector or right triangle cross-section. Four log parts matching in size and shape, and positioned so that their right angles form the corners of a rectangle, are assembled into a converted log, the interior space between the four log parts being filled selectively with braces, supports, insulation, concrete for various applications.
Claims
2. The converted log product of claim 1, wherein said four log parts are right-angled sectors cut at the periphery of said at least one log, remaining portions of said log being available for use as conventional lumber.
3. The converted log product of claim 1, wherein said four log parts are right-angled sectors cut from the conventionally discarded core of at least one log, the outer portion of said at least one log having been removed from said core for conventional uses.
5. The converted log product of claim 2, wherein said four right-angled sectors have been cut from said at least one log's periphery by a first longitudinal chordal cut followed by a second radial cut at right angles to and bisecting said first chordal cut.
