Wood Splitting
Wood splitting (''riving'',"Riving" def. 1.b. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe. Woodworking In woodworking carpenters use a wooden siding which gets its name, clapboard, from originally being split from logs—the sound of the plank against the log being a clap. This is used in clapboard architecture and for wainscoting. Coopers use oak clapboards to make barrel staves. Split-rail fences are made with split wood. Basket making Some Native Americans traditionally make baskets from black ash by pounding the wood with a mallet and pulling long strips from the log. Firewood Log splitting is the act of splitting firewood from logs that h ...

Merlin Usteye Bokion
Merlin ( cy, Myrddin, kw, Marzhin, br, Merzhin) is a mythical figure prominently featured in the legend of King Arthur and best known as a mage, with several other main roles. His usual depiction, based on an amalgamation of historic and legendary figures, was introduced by the 12th-century British author Geoffrey of Monmouth. It is believed that Geoffrey combined earlier tales of Myrddin and Ambrosius, two legendary Briton prophets with no connection to Arthur, to form the composite figure called Merlinus Ambrosius ( cy, Myrddin Emrys, br, Merzhin Ambroaz). Geoffrey's rendering of the character became immediately popular, especially in Wales. Later writers in France and elsewhere expanded the account to produce a fuller image, creating one of the most important figures in the imagination and literature of the Middle Ages. Merlin's traditional biography casts him as an often-mad being born of a mortal woman, sired by an incubus, from whom he inherits his supernatural power ...

Panelling
Panelling (or paneling in the U.S.) is a millwork wall covering constructed from rigid or semi-rigid components. These are traditionally interlocking wood, but could be plastic or other materials. Panelling was developed in antiquity to make rooms in stone buildings more comfortable both by insulating the room from the stone, and reflecting radiant heat from wood fires, making heat more evenly distributed in the room. In more modern buildings, such panelling is often installed for decorative purposes. Panelling, such as wainscoting and boiserie in particular, may be extremely ornate and is particularly associated with 17th and 18th century interior design, Victorian architecture in Britain, and its international contemporaries. Wainscot panelling The term wainscot ( or ) originally applied to high quality riven oak boards. Wainscot oak came from large, slow-grown forest trees, and produced boards that were knot-free, low in tannin, light in weight, and easy to work w ...

Pilot Hole
In construction, a pilot hole is a small hole drilled into a piece of construction material. Its purpose may be: #to guide a larger drill to the appropriate location and ease the job of the larger drill #allow for the insertion of another hole-making tool, such as a knockout punch, that will produce the final-sized hole, or #locate, guide, and provide clearance for a self-threading screw in wood or plastic to prevent damaging the material or breaking the screw. Pilot for large holes A pilot hole may be drilled the full extent of the final hole, or may only be a portion of the final depth. The pilot drill may be a standard twist drill, another type of drill bit appropriate for the material, or, when the primary purpose is precisely locating a hole, may be made with a short, stiff center drill. The pilot hole also reduces the power needed to turn a large drill bit, and reduces the large bit breakage risk. For twist drill bits, the pilot size is usually selected so that the c ...

Truss Connector Plate
A truss connector plate, or gang plate, is a kind of tie. Truss plates are light gauge metal plates used to connect prefabricated light frame wood trusses. They are produced by punching light gauge galvanized steel to create teeth on one side. The teeth are embedded in and hold the wooden frame components to the plate and each other. Nail plates are used to connect timber of the same thickness in the same plane. When used on trusses, they are pressed into the side of the timber using tools such as a hydraulic press or a roller. As the plate is pressed in, the teeth are all driven into the wood fibers simultaneously, and the compression between adjacent teeth reduces the tendency of the wood to split. A truss connector plate is manufactured from ASTM A653/A653M, A591, A792/A792M, or A167 structural quality steel and is protected with zinc or zinc-aluminum alloy coatings or their stainless steel Stainless steel is an alloy of iron that is resistant to rusting and corrosion. ...

Butterfly Joint
A butterfly joint, also called a bow tie, dovetail key, Dutchman joint, or Nakashima joint, is a type of joint or inlay used to hold two or more pieces of woods together. These types of joints are mainly used for aesthetics, but they can also be used to reinforce cracks in pieces of wood, doors, picture frames, or drawers. A dovetail key resembles two dovetails connected at the narrow part. A negative of the hole is cut out of the board the butterfly will be placed in and the butterfly is then fitted, keeping the joint together. The wood used for the butterfly is usually a contrasting wood, often walnut. History Dutchman Joint The term Dutchman is used when a patch or inlay covers a miss-cut or an imperfect piece of wood. A Dutchman can also cover a knot in the wood. A Dutchman can be wood or metal. The origin of the name is from San Francisco after the gold rush. All types of European craftsmen came to California to earn a living. The term Dutchman is slang given to the woo ...

Treenail
A treenail, also trenail, trennel, or trunnel, is a wooden peg, pin, or dowel used to fasten pieces of wood together, especially in timber frames, covered bridges, wooden shipbuilding and boat building. It is driven into a hole bored through two (or more) pieces of structural wood (mortise and tenon). History and general use The use of wood as a tenon can be traced back over 7,000 years, as archaeologist have found traces of wood nails in the excavation of early Germanic sites. Trenails are extremely economical and readily available, making them a common early building material. Black Locust is a favorite wood when making trunnels in shipbuilding in North America and English Oak in Europe due to their strength and rot resistance, while red oak is typical in buildings. Traditionally treenails and pegs were made by splitting bolts of wood with a froe and shaping them with a drawknife on a shaving horse. Treenails are cut from a single piece of wood and perform well because of ...

Shake (shingle)
Wood shingles are thin, tapered pieces of wood primarily used to cover roofs and walls of buildings to protect them from the weather. Historically shingles, also known as shakes, were split from straight grained, knot free ''bolts'' of wood. Today shingles are mostly made by being cut which distinguishes them from shakes, which are made by being split out of a bolt. Wooden shingle roofs were prevalent in the North American colonies (for example in the Cape-Cod-style house), while in central and southern Europe at the same time, thatch, slate and tile were the prevalent roofing materials. In rural Scandinavia, wood shingle roofs were a common roofing material until the 1950s. Wood shingles are susceptible to fire and cost more than other types of shingle so they are not as common today as in the past. Distinctive shingle patterns exist in various regions created by the size, shape, and application method. Special treatments such as swept valleys, combed ridges, decorative but ...

Viking Ship
Viking ships were marine vessels of unique structure, used in Scandinavia from the Viking Age throughout the Middle Ages. The boat-types were quite varied, depending on what the ship was intended for, but they were generally characterized as being slender and flexible boats, with symmetrical ends with true keel. They were clinker built, which is the overlapping of planks riveted together. Some might have had a dragon's head or other circular object protruding from the bow and stern for design, although this is only inferred from historical sources. Viking ships were used both for military purposes and for long-distance trade, exploration and colonization. In the literature, Viking ships are usually seen divided into two broad categories: merchant ships and warships, the latter resembling narrow "war canoes" with less load capacity, but higher speed. However, these categories are overlapping; some transport ships would also form part of war fleets. As a rule, ship lanes in Scandin ...

Batoning
Batoning is the technique of cutting or splitting wood by using a baton-sized stick or mallet to repeatedly strike the spine of a sturdy knife, chisel or blade in order to drive it through wood, similar to how a froe is used. The batoning method can be used to make kindling or desired forms such as boards, slats or notches. The practice is most useful for obtaining dry wood from the inside of logs for the purpose of fire making. Tools Tools used in batoning are: a strong, fixed-blade, preferably full tang knife or machete with a thick spine, and a club-sized length of dense or green wood for striking the knife's spine and tip. Technique The basic method involves repeatedly striking the spine of the knife to force the middle of the blade into the wood. The tip is then struck, to continue forcing the blade deeper, until a split is achieved. Uses and advantages This technique is useful for the simple splitting of wood for kindling, to access dry wood within a wet log, and for the ...

Log Splitter
A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic pump or electric motor which than powers a hydraulic or electrical rod and piston assembly. Generally these are often rated by the tons of force they can generate. The higher the force rating, the greater the thickness or length of the rounds that can be split. The log splitter consists of all four major hydraulic components. Most log splitter models for home use have a rating around 10 tons, but professional hydraulic models may exert 30 tons of force or more. There are also manual log splitters, which use mechanical leverage to force logs through a sharpened blade assembly; and screw or 'corkscrew' types that are driven directly from an agricultural tractor's power take-off shaft where the splitter is mounted on the three-point hitch. Power s ...

Log Bucking
A crew of log buckers with crosscut saws in 1914. Bucker limbing dead branch stubs with a chainsaw, also known as knot bumping Bucker making a bucking cut with a chainsaw Bucking is the process of cutting a felled and delimbed tree into logs. Significant value can be lost by sub-optimal bucking because logs destined for plywood, lumber, and pulp each have their own value and specifications for length, diameter, and defects. Cutting from the top down is ''overbucking'' and from the bottom up is '' underbucking''. In British English, the process is called logging-up or crosscutting. Methods A felled and delimbed tree is cut into logs of standard sizes, a process called ''bucking''. A logger who specialises in this job is a ''buck sawyer''. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of the limbs have broken off during ...

Fraxinus Nigra
''Fraxinus nigra'', the black ash, is a species of ash native to much of eastern Canada and the northeastern United States, from western Newfoundland west to southeastern Manitoba, and south to Illinois and northern Virginia. Formerly abundant, as of 2014 the species is threatened with near total extirpation throughout its range, as a result of infestation by a parasitic insect known as the emerald ash borer. Description Black ash is a medium-sized deciduous tree reaching (exceptionally ) tall with a trunk up to diameter, or exceptionally to . The bark is grey, thick and corky even on young trees, becoming scaly and fissured with age. The winter buds are dark brown to blackish, with a velvety texture. The leaves are opposite, pinnately compound, with 7–13 (most often 9) leaflets; each leaf is long, the leaflets long and broad, with a finely toothed margin. The leaflets are sessile, directly attached to the rachis without a petiolule. The flowers are produced in spr ...
