Hewing
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. Definitions ''Hew'' is a general term meaning to strike or blow with a tool such as an axe or sword; to chop or gash, and is used in warfare, stone and woodcutting, and coal and salt mining in this sense. Hewing wood is to shape the wood with a sharp instrument such as an axe, specifically flattening one or more sides of a log.

Broadaxe
A broadaxe is a large (broad)-headed axe. There are two categories of cutting edge on broadaxes, both are used for shaping logs by hewing. On one type, one side is flat, and the other side beveled, a basilled edge, also called a side axe, single bevel, or chisle-edged axe. On the other type, both sides are beveled, sometimes called a double bevel axe, which produces a scalloped cut. On the basilled broadaxe the handle may curve away from the flat side to allow an optimal stance by the hewer in relation to the hewn surface. The flat blade is to make the surface flat but can only be worked from one direction and is right-handed or left-handed. The double bevel axe has a straight handle and can be swung with either side against the wood. A double beveled broad axe can be used for chopping or notching as well as hewing. When used for hewing, notches are chopped in the side of the log down to a marked line, a process called scoring. The pieces of wood between these notches are remov ...

Dog (engineering)
In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axe Ties
Axe ties are railway ties (or sleeper) that are hewn by hand, usually with a broadaxe. There are 2,900 ties per mile of track on a first class railroad. The early railways would not accept ties cut with a saw, as it was claimed that the kerf of the saw splintered the fibres of the wood, leaving them more likely to soak up moisture causing premature rot. The process Geoff Marples wrote an account of being a ''tiehack'' in the East Kootenays in 1938 and described the process of making axe ties to include: December 2000. Victoria, B. C., Forest History Association of British Columbia. p. 1-4. print. First a suitable tree was chosen and then '' |
Sawmill
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logging, logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The Portable sawmill, "portable" sawmill is of simple operation. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation. Before the invention of the sawmill, boards were made in various manual labour, manual ways, either wood splitting, rived (split) and plane (tool), planed, hewing, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Framing
Timber framing (german: Holzfachwerk) 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. 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, where timber-framed houses are spread all over the country. The method comes from working directly from logs and trees rather than pre-cut dimensional lumber. Hewing this with broadaxes, adzes, and draw knives and using hand-powered braces and augers (brace and bit) and other woodworking tools, artisans or framers could gradually assemble a building. Since this building method has been used for thousands of years in many parts of the world, many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeim 2005-09-17 Fachwerk-05
Northeim (; nds, Nuurten) is a town in Lower Saxony, Germany, seat of the district of Northeim, with, in 2011, a population of 29,000. It lies on the German Half-Timbered House Road. History Northeim is first mentioned in 800 in a document recording a property transfer by a Frankish nobleman to the Abbey of Fulda. In the 10th century the surrounding region became a county, administered by the Counts of Northeim. The first of them, Siegfried is mentioned in 982. From 1061 to 1070 Count Otto II held the stem duchy of Bavaria as an Imperial fief, but lost it again because of his involvement in the Saxon plot against King Henry IV. The monastery of St. Blasius was founded around 1100. In 1252 Northeim obtained town rights, and from 1384 to 1554 it was a member of the Hanseatic League. When protestantism was introduced in 1532 all the churches were allocated to the protestants. The town became part of the Kingdom of Hanover. A part of Northeim was devastated by a fire in 1 ...

Woodworking
Woodworking is the skill of making items from wood, and includes cabinet making (cabinetry and furniture), wood carving, joinery, carpentry, and woodturning. History Along with stone, clay and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials. Among early finds of wooden tools are the worked sticks from Kalambo Falls, Clacton-on-Sea and Lehringen. The spears from Schöningen (Germany) provide some of the first examples of wooden hunting gear. Flint tools were used for carving. Since Neolithic times, carved wooden vessels are known, for example, from the Linear Pottery culture wells at Kückhofen and Eythra. Examples of Bronze Age wood-carving include tree trunks worked into coffins from nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Plane
The Japanese plane or is a plane pulled towards the user rather than pushed in the manner of western style planes. They are made of hardwood, usually Japanese white or red oak. The laminated steel and iron blade is stout compared to western planes. Tapered in length and thickness, the plane blade is its own wedge, as it fits into a correspondingly-shaped mortice in the body of the plane, thus dispensing the need for a separate wedge to hold the blade in place, as is the case in most other traditional wooden planes. The chip breaker is held in place with a simple nail inserted some distance away from and perpendicular to the axis of the main blade. The chip breaker is not tapered like the main blade; instead, it has bent "ears" that bear down on the plane blade. Chip breakers in Japan were introduced relatively recently, during the Meiji period. The soles of Japanese planes also have different configurations for varying applications. The apparently simple design disguises a great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drawknife
A drawknife (drawing knife, draw shave, shaving knife) is a traditional woodworking hand tool used to shape wood by removing shavings. It consists of a blade with a handle at each end. The blade is much longer (along the cutting edge) than it is deep (from cutting edge to back edge). It is pulled or "drawn" (hence the name) toward the user. The drawknife in the illustration has a blade long, although much shorter drawknives are also made. The blade is sharpened to a chisel bevel. Traditionally, it is a rounded, smooth bevel. The handles can be below the level of the blade (as in the illustration) or at the same level. Straight cuts One works from the centre of the piece to the end, not the entire length all at once. The operator then reverses the piece in the shaving horse or vise and works from near centre to trim the "fatter" end to match the centre and just finished original "skinny" end. Final work can be done by spokeshave, sanding block or lathe. *When operated conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Plane
A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used. Generally, all planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber. Planing is also used to produce horizontal, vertical, or inclined flat surfaces on workpieces usually too large for shaping, where the integrity of the whole requires the same smooth surface. Special types of planes are designed to cut joints or decorative mouldings. Hand planes are generally the combination of a cutting edge, such as a sharpened metal plate, attached to a firm body, that when moved over a wood surface, take up relatively uniform shavings, by nature of the body riding on the 'high spots' in the wood, and also by providing a relatively constant angle ...

Use-wear Analysis
Use-wear analysis is a method in archaeology to identify the functions of artifact tools by closely examining their working surfaces and edges. It is mainly used on stone tools, and is sometimes referred to as "traceological analysis" (from the neologism ''traceology''). In studying the wear on a lithics, different techniques are often used. A distinction is often made between use-wear and microwear analysis. Use-wear uses an approach of low magnification study while micro-wear employs high magnification; this raises contentions as to which approach is more useful. Therefore, use-wear studies regularly employ magnification up to 50x, while magnification beyond 50x is relegated to microwear analysis. In addition to the two groups of magnification in which researchers align themselves, a third group examines evidence of use by attempting to identify organic residues present on a lithic. The organic residues are analyzed in order to understand the activities the lithics were used for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adze
An adze (; alternative spelling: adz) is an ancient and versatile cutting tool similar to an axe but with the cutting edge perpendicular to the handle rather than parallel. Adzes have been used since the Stone Age. They are used for smoothing or carving wood in hand woodworking, and as a hoe for agriculture and horticulture. Two basic forms of an adze are the hand adze (short hoe)—a short-handled tool swung with one hand—and the foot adze (hoe)—a long-handled tool capable of powerful swings using both hands, the cutting edge usually striking at foot or shin level. A similar tool is called a mattock, which differs by having two blades, one perpendicular to the handle and one parallel. History Africa The adze is depicted in ancient Egyptian art from the Old Kingdom onward. Originally the adze blades were made of stone, but already in the Predynastic Period copper adzes had all but replaced those made of flint. stone blades were fastened to the handle by tying and earl ...
