In some medieval Scandinavian buildings a special method of hewing which produces a herringbone pattern on the timbers has been used (Swedish: Slinthuggning, Norwegian: Sprettejling). This is a modern reconstruction in Strasjo Chapel in Halsingland, Sweden. Strasjo kapell wood surface.jpg

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. [1] [2] Hewing wood is to shape the wood with a sharp instrument such as an axe, [3] 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 history.

Prepare log

After a tree is selected and felled, hewing can take place where the log landed or be skidded or twitched (skidded with a horse or oxen) out of the woods to a work site. The log is placed across two other smaller logs near the ground or up on trestles about waist height; stabilized either by notching the support logs, or using a 'timber dog' (also called a log dog, [4] a long bar of iron with a tooth on either end that jams into the logs and prevents movement). The hewer measures and locates the timber within the log on both ends and marks lines along the length of a log, usually with a chalk line.

Scoring

The next step is to chop notches every foot or two, almost as deep as the marked line using a chopping or scoring axe, called scoring. At least three methods are used in scoring. 1) Standing on the log and swinging an axe to chop the score; 2) In Germany a method of two carpenters standing on the ground with the log on trestles and swinging downward to slice the scores. (see video in link below); 3) A chainsaw is used to notch the log, the sections created by the notching are then split off using a felling axe.

Joggling or juggling

The pieces of wood between the notches are knocked off with an axe, this process called juggling [5] [6] or joggling. [7] This results in a rough surface pared down just shy of the marked line. Scoring and juggling remove a fair amount of wood, make hewing easier and prevent long shreds of wood being torn off.

Hewing

Hewing is the last step in this whole process, which is also collectively referred to as hewing. Hewing is done on the logs sides with a broadaxe. Hewing occurs from the bottom of the stem upwards towards what was the top of the standing tree, reducing the tendency of the broken fibers to migrate inwards towards the eventual beam. [8]

It is widely published that an adze was used to hew the top surface of a log flat in the same manner as an axe is used on the sides of a log. However, physical evidence of looking at the marks left by the hewing tools in historic buildings, called tracology, are swung in an arc and thus made by an axe, not an adze.[ citation needed ] Shipbuilders frequently used adzes in shaping ship timbers, the choice of tool being made by the position of the surface being hewn, the sides best hewn with an axe and the face best hewn with an adze. Historic illustrations do show some Asian carpenters hewing building timbers with an adze. Further smoothing can then be done using a hand plane, drawknife, yariganna (an ancient Japanese cutting tool) or any other established or improvised means.

Some 19th-century timber buildings in the U.S. have hewn long timbers in the same framing with vertically sawn and the later technology of circular sawn timbers. The reason for this is the long timbers were easier to hew with an axe than to take to a sawmill due to poor transportation routes.

Hewn railroad ties are known as axe ties and were made by a tiehacker. [9]

Modern uses

Although still used in niche modern building, salvaged hand-hewn beams are now commonly recycled as architectural details popular in new construction and renovation of homes. They are also popular as decor in commercial and restaurant spaces. [10]

Lumber is wood that has been processed into uniform and useful sizes, including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing. Lumber has many uses beyond home building. Lumber is sometimes referred to as timber in England, Australia and New Zealand, while in most parts of the world the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut.

<span class="mw-page-title-main">Circular saw</span> Power tool

A circular saw is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A hole saw and ring saw also use a rotary motion but are different from a circular saw. Circular saws may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century.

<span class="mw-page-title-main">Adze</span> Woodworking tool with the cutting edge perpendicular to the handle

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 for agriculture and horticulture. Two basic forms of an adze are the hand adze —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.

<span class="mw-page-title-main">Broadaxe</span> Type of axe with a large head that is primarily used as a tool

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.

<span class="mw-page-title-main">Sawmill</span> Facility where logs are cut into lumber

A sawmill or lumber mill is a facility where 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. The "portable" sawmill is simple to operate. 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, with similar horizontal operation.

<span class="mw-page-title-main">Hatchet</span> Single-handed striking tool

A hatchet is a single-handed striking tool with a sharp blade on one side used to cut and split wood, and a hammerhead on the other side. Hatchets may also be used for hewing when making flattened surfaces on logs; when the hatchet head is optimized for this purpose it is called a hewing hatchet.

<span class="mw-page-title-main">Timber framing</span> Traditional building technique

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. 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.

<span class="mw-page-title-main">Log house</span> House built from wooden logs

A log house, or log building, is a structure built with horizontal logs interlocked at the corners by notching. Logs may be round, squared or hewn to other shapes, either handcrafted or milled. The term "log cabin" generally refers to a smaller, more rustic log house, such as a hunting cabin in the woods, that may or may not have electricity or plumbing.

<span class="mw-page-title-main">Sawhorse</span> Structure for supporting lumber workpieces during sawing

In woodworking, a saw-horse or sawhorse is a trestle structure used to support a board or plank for sawing. A pair of sawhorses can support a plank, forming a scaffold. In certain circles, it is also known as a mule and a short sawhorse is known as a pony. The names come from the shape of the frame, which resembles a horse. A sawhorse may also be a rack for supporting logs for sawing, known in the US as a sawbuck.

Axe ties are railway ties 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.

<span class="mw-page-title-main">Quarter sawing</span> Woodworking process

Quarter sawing or quartersawing is a woodworking process that produces quarter-sawn or quarter-cut boards in the rip cutting of logs into lumber. The resulting lumber can also be called radially-sawn or simply quartered. There is widespread confusion between the terms rift sawn and quarter sawn with the terms defined both with opposite meanings and as synonyms.

This glossary of woodworking lists a number of specialized terms and concepts used in woodworking, carpentry, and related disciplines.

<span class="mw-page-title-main">Reclaimed lumber</span> Processed wood reused for other applications

Reclaimed lumber is processed wood retrieved from its original application for purposes of subsequent use. Most reclaimed lumber comes from timbers and decking rescued from old barns, factories and warehouses, although some companies use wood from less traditional structures such as boxcars, coal mines and wine barrels. Reclaimed or antique lumber is used primarily for decoration and home building, for example for siding, architectural details, cabinetry, furniture and flooring.

<span class="mw-page-title-main">Axe</span> Type of wedge tool

An axe is an implement that has been used for millennia to shape, split, and cut wood, to harvest timber, as a weapon, and as a ceremonial or heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a handle, also called a haft or a helve.

A cleaving axe or cleaver is a form of axe used within green woodworking to split wood lengthways. Cleaving (riving) is used to turn a log into lumber or billets into firewood. Splitting axe is sometimes described as an old name for a splitting maul or froe.

Rift sawing is a woodworking process that aims to produce lumber that is less vulnerable to distortion than flat-sawn lumber. Rift-sawing may be done strictly along a log's radials—perpendicular to the annular growth ring orientation or wood grain—or as part of the quarter sawing process.
