The logs (16) are milled by cutting them along radial and longitudinally extending lines (17, 17', 50) to form elongated wedge shaped elements (32, 36, 36', 36'', 45, 52, 52') either separate from one another or laminated to one another such that the growth rings in the respective elements are generally perpendicular to the cut side surfaces (17, 17') of the elements, and when laminated the growth rings of all such elements are generally parallel to one another. |
