Wandering heart

Last updated

Wandering heart is a fault in timber, where the heart of the tree wanders from side to side, rather than remaining central. This is usually caused by sustained winds. The resulting boards are twisted and short grained, and not suitable for construction due to their tendency to warp, and their weakness. [1]

Wood Fibrous material from trees or other plants

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

Lumber wood that has been processed into beams and planks

Lumber or timber is a type of wood that has been processed into beams and planks, a stage in the process of wood production. Lumber is mainly used for structural purposes but has many other uses as well.

Hewing method for converting a log into lumber

In woodworking, hewing is the process of converting a log from its rounded natural form into lumber (timber) with more or less flat surfaces using primarily an axe. It is an ancient method, and before the advent of the industrial-era type of sawmills, it was a standard way of squaring up wooden beams for timber framing. Today it is still used occasionally for that purpose by anyone who has logs, needs beams, and cannot or would prefer not to pay for finished lumber. Thus homesteaders on frugal budgets, for example, may hew their own lumber rather than buy it.

Timber framing building technique, construction method using heavy squared-off and carefully fitted and joined timbers

Timber framing and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. It is commonplace in wooden buildings through the 19th century. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany. Timber framed houses are spread all over the country except in the southeast.

Deathwatch beetle Species of woodboring beetle

The deathwatch beetle is a species of woodboring beetle that sometimes infests the structural timbers of old buildings. The adult beetle is brown and measures on average 7 mm (0.3 in) long. Eggs are laid in dark crevices in old wood inside buildings, trees, and inside tunnels left behind by previous larvae. The larvae bore into the timber, feeding for up to ten years before pupating, and later emerging from the wood as adult beetles. Timber that has been damp and is affected by fungal decay is soft enough for the larvae to chew through. They obtain sufficient nourishment by using a number of enzymes present in their gut to digest the cellulose and hemicellulose in the wood.

Waterline special marking that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise

The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line, that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with the same lessening effect upon buoyancy.

Shiver my timbers

"Shiver me timbers" is an exclamation in the form of a mock oath usually attributed to the speech of pirates in works of fiction. It is employed as a literary device by authors to express shock, surprise or annoyance. The phrase is based on real nautical slang and is a reference to the timbers, which are the wooden support frames of a sailing ship. In heavy seas, ships would be lifted up and pounded down so hard as to "shiver" the timbers, startling the sailors. Such an exclamation was meant to convey a feeling of fear and awe, similar to, "Well, blow me down!", or, "May God strike me alive and well". Since on the high seas the ship was the sailors 'world', may also be interpreted as an exclamation for "shake my world" as the subject being referred to could be, or may be considered a potentially 'world shaking' event. "Shiver" is also reminiscent of the splintering of a ship's timbers in battle – splinter wounds were a common form of battle injury on wooden ships. Can also be used as an expression of being "cold to the bone".
