Phoenician Joint
A Phoenician joint () is a locked mortise and tenon wood joinery technique used in shipbuilding to fasten watercraft Hull (watercraft), hulls. The locked (or pegged) mortise and tenon technique consists of cutting a mortise, or socket, into the edges of two planks and fastening them together with a rectangular wooden knob. The assembly is then locked in place by driving a dowel through one or more holes drilled through the mortise side wall and tenon. The Phoenicians pioneered the use of locked mortise and tenon joints in nautical joinery to secure the underwater planking of seagoing ships. The use of pegged mortises and tenons in shipbuilding spread westward from the Phoenicia, Levantine littoral. Examples of the use of Phoenician joints in the ancient Mediterranean include the Uluburun shipwreck, Uluburun ship, dated , and the Cape Gelidonya ship dated to . By the first millennium BC, Phoenician joints became a common edge-to-edge fastening method. Ancient Greece, Ancient Gree ...

Mortise And Tenon
A mortise and tenon (occasionally mortice and tenon) is a Woodworking joints, joint that connects two pieces of wood or other material. Woodworking, Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles, though it can be used to connect two work pieces at any angle. Mortise-and tenon-joints are simple, strong, and stable, and can be used in many projects and which give an attractive look. They are either glued or friction-fitted into place. This joint is difficult to make, because of the precise measuring and tight cutting required; as such, modern woodworkers often use machinery specifically designed to cut mortises and matching tenons quickly and easily. Still, many woodworkers cut them by hand in a traditional manner. There are many variations of this type of joint, but its basic structure has two components, the ''mortise'' hole and the ''tenon'' tongue. The tenon, formed on the end o ...

Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...

Wood Drying
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: ; Woodworking:When wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or expel moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood. ; Wood burning: When wood is burned (firewood), it is usually best to dry it first. Damage from shrinkage is not a problem here, as it may be in the case of drying for woodworking purposes. Moisture affects the burning process, with unburnt hydrocarbons going up the chimney.

Hellenistic-era Warships
From the 4th century BC on, new types of oared warships appeared in the Mediterranean Sea, superseding the trireme and transforming naval warfare. Ships became increasingly large and heavy, including some of the largest wooden ships hitherto constructed. These developments were spearheaded in the Hellenistic Near East, but also to a large extent shared by the naval powers of the Western Mediterranean, specifically Carthage and the Roman Republic. While the wealthy successor kingdoms in the East built huge warships ("polyremes"), Carthage and Rome, in the intense naval antagonism during the Punic Wars, relied mostly on medium-sized vessels. At the same time, smaller naval powers employed an array of small and fast craft, which were also used by the ubiquitous pirates. Following the establishment of complete Roman hegemony in the Mediterranean after the Battle of Actium, the nascent Roman Empire faced no major naval threats. In the 1st century AD, the larger warships were retained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shekel
A shekel or sheqel (; , , plural , ) is an ancient Mesopotamian coin, usually of silver. A shekel was first a unit of weight—very roughly 11 grams (0.35 ozt)—and became currency in ancient Tyre, Carthage and Hasmonean Judea. Name The word is based on the triliteral Proto-Semitic root , cognate to the Akkadian or , a unit of weight equivalent to the Sumerian . Use of the word was first attested in under the reign of Naram-Sin of Akkad, and later in in the Code of Hammurabi. The Hebrew reflex of the root is found in the Hebrew words for "to weigh" (), "weight" () and "consideration" (). It is cognate to the Aramaic root and the Arabic root ( ث ق ل, in words such as "weight", "heavy" or , a unit of weight). The famous writing on the wall in the Book of Daniel includes a cryptic use of the word in Aramaic: "". Shekel came into the English language via the Hebrew Bible, where it is first used in Genesis 23. The term "shekel" has been used for a unit of we ...

Sheer (ship)
The sheer is a measure of longitudinal main deck curvature in naval architecture. The sheer forward is usually twice that aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship. In the early days of sail, one discussed a hull's sheer in terms of how much "hang" it had. William Sutherland's ''The Ship-builders Assistant'' (1711) covers this information in more detail. The practice of building sheer into a ship dates back to the era of small sailing ship A sailing ship is a sea-going vessel that uses sails mounted on Mast (sailing), masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing Square rig, square-rigged or Fore-an ...s.

Strake
On a vessel's Hull (watercraft), hull, a strake is a longitudinal course of Plank (wood), planking or Plate (metal), plating which runs from the boat's stem (ship), stempost (at the Bow (ship), bows) to the stern, sternpost or transom (nautical), transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both Carvel (boat building), carvel and clinker (boat building), clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarf joint, scarfed, or Butt joint, butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a Rivet, riveted steel ship, the strakes were usually lapped and ...

Lashed-lug Boat
Lashed-lug boats are ancient boat-building techniques of the Austronesian peoples. It is characterized by the use of raised lugs (also called "cleats") on the inner face of hull planks. These lugs have holes drilled in them so that other hull components such as ribs, thwarts or other structural components can be tied to them with natural fiber ropes (hence "lashed"). This allows a structure to be put together without any metal fastenings. The planks are further stitched together edge-to-edge by sewing or using dowels (" treenails") unto a dugout keel and the solid carved wood pieces that form the caps for the prow and stern. Characteristically, the shell of the boat is created first, prior to being lashed unto ribs. The seams between planks are also sealed with absorbent tapa bark and fiber that expands when wet or caulked with resin-based preparations. Lashed-lug construction has been used on a wide size range of vessels, from small craft, such as logboats that have had plank ...
