Hand-Hewn
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 the 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. Methods As an ancient method of timber ''conversion'', different methods of each step in hewing have developed in hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeim 2005-09-17 Fachwerk-05
Northeim (; ) is a town in Lower Saxony, Germany, seat of the Northeim (district), district of Northeim, with a population of 30,118 as of 31 December 2023. 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 County of Northeim, a county, administered by the Counts of Northeim. The first of them, Siegfried, Count of Northeim, Siegfried is mentioned in 982. From 1061 to 1070 Count Otto of Northeim, Otto II held the stem duchy of Duchy of Bavaria, Bavaria as an Imperial fief, but lost it again because of his involvement in the Saxon plot against Henry IV, Holy Roman Emperor, King Henry IV. The monastery of St. Blasius was founded around 1100. In 1252 Northeim obtained German town law, town rights, and from 1384 to 1554 it was a member of the Hanseatic League. When protestantism was introduced in 1532 all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk Line
A chalk line or chalk box is a tool for marking long, straight lines on relatively flat surfaces, much further than is practical by hand or with a straightedge. They may be used to lay out straight lines between two points, or vertical lines by using the weight of the line reel as a plumb line. It is an important tool in carpentry, and the working of timber in a rough and unplaned state, as it does not require the timber to have a straight or squared edge formed onto it beforehand. Use A chalk line creates straight lines by the action of a taut Twine, string that has been previously coated with a loose, powdered dye, usually chalk. The string is then laid across the surface to be marked and pulled tight. Next, the string is wikt:pluck, plucked or snapped sharply, causing it to strike the surface, which then transfers its chalk to the surface along the straight line where it struck. Chalk lines are typically used to mark relatively flat surfaces. However, as long as the line is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Woodworking
Green woodworking (also written greenwoodworking) is a form of woodworking that uses unseasoned or "green" timber. The term "unseasoned" refers to wood that has been freshly felled or preserved by storing it in a water-filled trough or pond to maintain its naturally high moisture content. This wood is much softer than seasoned timber and is therefore much easier to shape with hand tools. As moisture leaves the unseasoned wood, shrinkage occurs. This can be used as an advantage, as this shrinkage can help ensure tight joints. To enhance the effect of the shrinkage, a half of a joint may be forcibly over-dried in a simple kiln while its encapsulating component is left green. The components tighten against each other as the parts exchange moisture and approach equilibrium with the surrounding environment. The swelling of the dry tenon inside the shrinking “green” mortise makes for an incredibly tight and permanent joint despite a lack of adhesives. Bodging is a traditional green wo ...

Woodworking
Woodworking is the skill of making items from wood, and includes cabinetry, furniture making, 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 the earlliest finds of woodworking are shaped sticks displaying notches from Kalambo Falls in southen Africa, dating to around 476,000 years ago.

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.

Japanese Plane
The Japanese plane or is a Plane (tool), 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 disg ... [...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. Purpose A drawknife is commonly used to remove large slices of wood for flat faceted work, to debark trees, or to create roughly rounded or cylindrical billets for further work on a lathe, or it can shave like a spokeshave plane, where finer finishing is less of concern than a rapid result. The thin blade lends itself to create complex concave or convex curves. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Plane
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three digits of the bird hand involved the same homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: four fingers plus one thumb; however, these are often referred to collectively as five fingers, whereby the thumb is included as one of the fingers. It has 27 bones, not including the sesamoid bone, the numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Use-wear Analysis
Use-wear analysis is a method in archaeology Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, ... 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 o ...

Adze
An adze () or 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 (tool), 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 Egypt, Predynastic Period copper adzes had all but replaced those made of flint. Stone blades were fastened to the handle by tying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadaxe
A broadaxe is a large broad-headed axe. There are two categories of cutting edge on broadaxes, both are used for shaping logs into beams 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, and to allow clearance for the hewer's hands. 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 scorin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
