bow: a warp along the length of the face of the wood; crook: a warp along the length of the edge of the wood; kink: a localized crook, often due to a knot; cup: a warp across the width of the face, in which the edges are higher or lower than the center of the wood; twist or wind: a distortion in which the two ends do not lie on the same plane.
Re-sawing is the splitting of 1-to-12-inch (25–305 mm) hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a 10-foot-long (3.0 m) 2×4 ( 1 + 1 ⁄ 2 by 3 + 1 ⁄ 2 in or 38 by 89 mm) into two 1×4s ( 3 ⁄ 4 by 3 + 1 ⁄ 2 in or 19 by 89 mm) of the same length is considered re-sawing.
The Thermo wood process consists of drying, heat treatment and finally cooling/conditioning, and takes up to 72 hours. [4] The Plato process consists of hydrothermolysis, dry curing and conditioning, and can take up to 7 days. The required time depends on wood species, width and initial moisture content. [5]
If these layers are allowed to dry much below the fibre saturation point while the interior is still saturated, stresses (called drying stresses) are set up because the shrinkage of the outer layers is restricted by the wet interior (Keey et al., 2000). Rupture in the wood tissues occurs, and consequently splits and cracks occur if these ...
A number of proprietary features for solid wood floors are available. Many solid woods come with grooves cut into the back of the wood that run the length of each plank, often called 'absorption strips,' that are intended to reduce cupping. Solid wood floors are mostly manufactured 0.75 inches (19 mm) thick with a tongue-and-groove for ...
The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...
Floors using small (4.5 in or 11.4 cm and smaller) ceramic tiles generally use only an additional 1 ⁄ 4-inch (6.4 mm) layer of plywood (if that) and substitute adhesive and substrate materials making do with both a flexible joints and semi-flexible mounting compounds and so are designed to withstand the greater flexing which large tiles ...
