Wood and lumber
Live oak was widely used in early American butt shipbuilding. Because of the trees' short height and low hanging branches, lumber from live oak was specifically used to make curved structural members of the hull such as knee braces (single-piece inverted L-shape braces that spring inward from the side and support a ship's deck). In such cuts of lumber, the line of the grain would fall perpendicularly to lines of stress, creating structures of exceptional strength. Live oaks were not generally used for planking because the curved and often convoluted shape of the tree did not lend itself to be milled to planking of any length. Red oak or white oak was generally used for planking on vessels, as those trees tended to grow straight and tall and thus would yield straight trunk sections of length suitable for milling into plank lengths.
Live oak was largely logged out in Europe by the latter half of the 19th century, and was similarly sought after and exported from the United States until iron- and steel-hulled commercial vessel construction became the standard early in the 20th century. Live oak lumber is rarely used for furniture due to warping and twisting while drying.
It continues to be used occasionally when available in shipbuilding, as well as for tool handles for its strength, energy absorption, and density, but modern composites are often substituted with good effect. Dry southern live oak lumber has a specific gravity
Specific gravity is the ratio of the density of a substance to the density of a reference substance. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always water for...
