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 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 implements. 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 northern Germany and Denmark and wooden folding-chairs. The site of Fellbach-Schmieden in Germany has provided fine examples of wooden animal statues from the Iron Age. Wooden idols from the La Tène period known from a sanctuary at the source of the Seine in France.

Ancient Egypt


There is significant evidence of advanced woodworking in ancient Egypt. Woodworking is depicted in many extant ancient Egyptian drawings, and a considerable amount of ancient Egyptian furniture (such as stools, chairs, tables, beds, chests) have been preserved. Tombs represent a large collection of these artifacts and the inner coffins found in the tombs were also made of wood. The metal used by the Egyptians for woodworking tools was originally copper and eventually, after 2000 BC bronze as iron working was unknown until much later.

Commonly used woodworking tools included axes, adzes, chisels, pull saws, and bow drills. Mortise and tenon joints are attested from the earliest Predynastic period. These joints were strengthened using pegs, dowels and leather or cord lashings. Animal glue came to be used only in the New Kingdom period. Ancient Egyptians invented the art of veneering and used varnishes for finishing, though the composition of these varnishes is unknown. Although different native acacias were used, as was the wood from the local sycamore and tamarisk trees, deforestation in the Nile valley resulted in the need for the importation of wood, notably cedar, but also Aleppo pine, boxwood and oak, starting from the Second Dynasty.

Ancient Rome
Woodworking was essential to the Romans. It provided, material for buildings, transportation, tools, and household items. Wood also provided pipes, dye, waterproofing materials, and energy for heat. Although most examples of Roman woodworking have been lost, the literary record preserved much of the contemporary knowledge. Vitruvius dedicates an entire chapter of his De architectura to timber, preserving many details. Pliny, while not a botanist, dedicated six books of his Natural History to trees and woody plants, providing a wealth of information on trees and their uses.

Ancient China
The progenitors of Chinese woodworking are considered to be Lu Ban (魯班) and his wife Lady Yun, from the Spring and Autumn period (771 to 476 BC). Lu Ban is said to have introduced the plane, chalk-line, and other tools to China. His teachings were supposedly left behind in the book Lu Ban Jing (魯班經, "Manuscript of Lu Ban"). Despite this, it is believed that the text was written some 1500 years after his death. This book is filled largely with descriptions of dimensions for use in building various items such as flower pots, tables, altars, etc., and also contains extensive instructions concerning Feng Shui. It mentions almost nothing of the intricate glue-less and nail-less joinery for which Chinese furniture was so famous.

Modern day


With the advances in modern technology and the demands of industry, woodwork as a field has changed. The development of Computer Numeric Controlled (CNC) Machines, for example, has made it possible to mass-produce and reproduce products faster, with less waste, and often with more complex design than ever before. CNC wood routers can carve complicated and highly detailed shapes into flat stock, to create signs or art. Rechargeable power tools speed up creation of many projects and require much less body strength than in the past, for example when boring multiple holes. Skilled fine woodworking, however, remains a craft pursued by many. There remains demand for hand crafted work such as furniture and arts, however with rate and cost of production, the cost for consumers is much higher. Modern woodcarving usually refers to works of wood art produced by woodcarvers in the form of contemporary art. This type of wood carving often combines traditional techniques with more modern artistic styles and concepts. Modern woodcarving can be produced in a variety of forms and styles, from realist to abstract carvings, and often uses unusual wood materials such as rainwood or wood with unique textures to highlight the uniqueness of the work.In recent years, the art of modern wood carving has become increasingly popular among woodworkers and visual art enthusiasts not only in Asia, but also around the world. Modern woodcarving art is often exhibited in art galleries and museums, and can be seen in several global contemporary art exhibitions.

Styles and designs
Woodworking, especially furniture making, has many different designs/styles. Throughout its history, woodworking designs and styles have changed. Some of the more common styles are listed below. Traditional furniture styles usually include styles that have been around for long periods of time and have shown a mark of wealth and luxury for centuries. More modern furniture styles are commonly used over the past few hundred years.

Materials

Historically, woodworkers relied upon the woods native to their region, until transportation and trade innovations made more exotic woods available to the craftsman. Woods are typically sorted into three basic types: hardwoods typified by tight grain and derived from broadleaf trees, softwoods from coniferous trees, and man-made materials such as plywood and MDF.

Hardwoods, botanically known as angiosperms, are deciduous and shed their leaves annually with temperature changes. Softwoods come from trees botanically known as gymnosperms, which are coniferous, cone-bearing, and stay green year round. Although a general pattern, softwoods are not necessarily always “softer” than hardwoods, and vice versa.

Softwood is most commonly found in the regions of the world with lower temperatures and is typically less durable, lighter in weight, and more vulnerable to pests and fungal attacks in comparison to hardwoods. They typically have a paler color and a more open grain than hardwoods, which contributes to the tendency of felled softwood to shrink and swell as it dries. Softwoods usually have a lower density, around 432–592 kg/m3, which can compromise its strength. Density, however, does vary within both softwoods and hardwoods depending on the wood's geographical origin and growth rate. However, the lower density of softwoods also allows it to have a greater strength with lighter weight. In the United States, softwoods are typically cheaper and more readily available and accessible. Most softwoods are suitable for general construction, especially framing, trim, and finish work, and carcassing.

Hardwoods are separated into two categories, temperate and tropical hardwoods, depending on their origin. Temperate hardwoods are found in the regions between the tropics and poles, and are of particular interest to wood workers for their cost-effective aesthetic appeal and sustainable sources. Tropical hardwoods are found within the equatorial belt, including Africa, Asia, and South America. Hardwoods flaunt a higher density, around 1041 kg/m3 as a result of slower growing rates and is more stable when drying. As a result of its high density, hardwoods are typically heavier than softwoods but can also be more brittle. While there are an abundant number of hardwood species, only 200 are common enough and pliable enough to be used for woodworking. Hardwoods have a wide variety of properties, making it easy to find a hardwood to suit nearly any purpose, but they are especially suitable for outdoor use due to their strength and resilience to rot and decay. The coloring of hardwoods ranges from light to very dark, making it especially versatile for aesthetic purposes. However, because hardwoods are more closely grained, they are typically harder to work than softwoods. They are also harder to acquire in the United States and, as a result, are more expensive. Typically furniture such as tables and chairs is made using solid stock from hardwoods due to its strength and resistance to warping. Additionally, they also have a greater variety of grain patterns and color and take a finish better which allows the woodworker to exercise a great deal of artistic liberty. Hardwoods can be cut more cleanly and leave less residue on sawblades and other woodworking tools. Cabinet/fixture makers employ the use of plywood and other man made panel products. Some furniture, such as the Windsor chair involve green woodworking, shaping with wood while it contains its natural moisture prior to drying.

Cedar
Cedars are strong, aromatic softwoods that are capable of enduring outdoor elements, the most common of which is the western red cedar. Western red cedar can sustain wet environments without succumbing to rot, and as a result is commonly used for outdoor projects such as patios, outdoor furniture, and building exteriors. This wood can be easily found at most home centers in the US and Canada for a moderate price.

Fir
Within the USA fir, also known as Douglas fir, is inexpensive and common at local home centers. It has a characteristic straight, pronounced grain with a red-brown tint. However, its grain pattern is relatively plain and it does not stain well, so fir is commonly used when the finished product will be painted. While commonly used for building, this softwood would also be suitable for furniture-making.

Pine
White pine, ponderosa, and southern yellow pine are common species used in furniture-making. White pine and ponderosa are typically used for indoor projects, while Southern yellow pine is recommended for outdoor projects due to its durability.

Ash
This hardwood is relatively easy to work with and takes stain well, but its white to light brown color with a straight grain is visually appealing on its own. However, ash is much more difficult to find than other common woods, and will not be found at the local home center. Larger lumber yards should have it in stock.

Beech
Hardwood of the European species Fagus sylvatica is widely used for furniture framing and carcase construction, in plywood, musical instruments (drum shells and piano blocks) and turned items like knobs.

Birch
Whether yellow or white birch, these hardwoods are stable and easy to work with. Despite this, birch is prone to blotching when stained, so painting birch products is probably best. Birch is easily found at many home centers and is a relatively inexpensive hardwood.

Cherry
Popular and easy to work with, cherry is in high demand for its reddish-brown color and ease of staining and finishing. Cherry likely will not be at the local home center, but should be at a lumberyard for a somewhat expensive price. This hardwood is a very common material for furniture, and is resistant to normal wear-and-tear, but it is best for indoor pieces.

Mahogany
A hardwood, mahogany has a trademark reddish-brown to deep-red tint and is known as "one of the great furniture woods". However, mahogany is not typically grown in sustainable forests, and thus runs a steep price at local lumber yards.

Oak
With two varieties, red and white, oak is known to be easy to work with and relatively strong. However, furniture makers often opt for white oak over red oak for its attractive figure and moisture-resistance. Depending on the kind needed, oak can probably be found at a local home center or a lumberyard for a bit pricier than other hardwoods.

Maple
With strength, sturdiness, and durability, maple is a common material for furniture for the bedroom and even china cabinets. Maple is moisture-resistant and frequently displays stand-out swirls in the wood grain, an aesthetically pleasing differentiator from other hardwoods. While most commonly a lighter color, maple also can take stains and paint well.

Factors in choosing materials
There are many factors to consider when deciding what type of wood to use for a project. One of the most important is the workability of the wood: the way in which it responds when worked by hand or tools, the quality of the grain, and how it responds to adhesives and finishes. When the workability of wood is high, it offers a lower resistance when cutting and has a diminished blunting effect on tools. Highly workable wood is easier to manipulate into desired forms. If the wood grain is straight and even, it will be much easier to create strong and durable glued joints. Additionally, it will help protect the wood from splitting when nailed or screwed. Coarse grains require a lengthy process of filing and rubbing down the grain to produce a smooth result.

Another important factor is the durability of the wood, especially in regards to moisture. If the finished project will be exposed to moisture (e.g. outdoor projects) or high humidity or condensation (e.g. in kitchens or bathrooms), then the wood needs to be especially durable in order to prevent rot. Because of their oily qualities, many tropical hardwoods such as teak and mahogany are popular for such applications.

Woods used for carving
While many woods can be used for carving, there are some clear favorites, including aspen, basswood, butternut, black walnut, and oak. Because it has almost no grain and is notably soft, Basswood is particularly popular with beginner carvers. It is used in many lower-cost instruments like guitars and electric basses. Aspen is similarly soft, although slightly harder, and readily available and inexpensive. Butternut has a deeper hue than basswood and aspen and has a nice grain that is easy to carve, and thus friendly for beginners. It is also suitable for furniture. While more expensive than basswood, aspen, and butternut, black walnut is a popular choice for its rich color and grain. Lastly, oak is a strong, sturdy, and versatile wood for carving with a defined grain. It is also a popular wood for furniture making.

Tools
Each area of woodworking requires a different variation of tools. Power tools and hand tools are both used for woodworking. Many modern woodworkers choose to use power tools in their trade for the added ease and to save time. However, many woodworkers still choose to use only hand tools for several reasons such as tradition, the experience and the added character to the work, while some choose to use only hand tools simply for their own enjoyment.

Hand tools
Hand tools are classified as tools that receive power only from the hands that are holding them. Edged hand woodworking tools need to be sharpened which is done using the sharpening jig and sharpening stone. A more novel method involves the use of sandpaper. The more common modern hand tools are:

Power tools
Power tools are tools that are powered by an external energy such as a battery, motor, or a power cable connected to a wall outlet. The more common power tools are:
