Wood Grain
Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. Definition and meanings R. Bruce Hoadley wrote that ''grain'' is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., ''straight grain'', ''spiral grain''), surface appearance or figure, growth-ring placement (e.g., ''vertical grain''), plane of the cut (e.g., ''end grain''), rate of growth (e.g., ''narrow grain''), and relative cell size (e.g., ''open grain'').Hoadley, R. Bruce. "Glossary." ''Understanding Wood: A Craftsman's Guide to Wood Technology''. Newtown, Conn.: Taunton, 1980. 265. Print. Physical aspects Perhaps the most important physical aspect of wood grain in woodworking is the grain direction or slope (e.g. against the grain). The two basic categories of grain are straight and cross grain. Straight grain runs parallel to the longitudinal axis of the piece. Cross grain deviates from the longitudinal a ...

Burls
A burl (American English) or burr (British English) is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. Burl formation is typically a result of some form of stress such as an injury or a viral or fungal infection. Burls yield a very peculiar and highly figured wood sought after in woodworking, and some items may reach high prices on the wood market. Poaching of burl specimens and damaging the trees in the process poses a problem in some areas. Description A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Almost all burl w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Wood Finishing
Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs. Finishing is the final step of the manufacturing process that gives wood surfaces desirable characteristics, including enhanced appearance and increased resistance to moisture and other environmental agents. Finishing can also make wood easier to clean and keep it sanitized, sealing pores that can be breeding grounds for bacteria. Finishing can also influence other wood properties, for example tonal qualities of musical instruments and hardness of flooring. In addition, finishing provides a way of giving low-value woods the appearance of ones that are expensive and difficult to obtain. Planning the finish Finishing of wood requires careful planning to ensure that the finished piece looks attractive, performs well in service and meets safety and environmental requirements.

Knee (construction)
In woodworking, a knee is a natural or cut, curved piece of wood. Knees, sometimes called ships knees, are a common form of bracing in boat building and occasionally in timber framing. A knee rafter in carpentry is a bent rafter used to gain head room in an attic. Strength characteristics Wood is a highly anisotropic material (its strength varies considerably with the direction of applied force, i.e. parallel, radial, or tangential to the grain). Because wood is strongest when loaded in tension or compression along the grain, the best knees are those in which the wood grain follows the bend. For a knee with relatively little bend, it may be possible to cut the knee out of a single straight-grained board and still achieve sufficient strength. However, with increasing bend this method becomes problematic since more and more of the knee is aligned across the grain and is therefore considerably weaker. A knee laid out this way might easily snap in two under hand pressure alone, even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grain Filler
A grain filler (pore filler or paste wood filler) is a woodworking product that is used to achieve a smooth-textured wood finish by filling pores in the wood grain. It is used particularly on open grained woods such as oak, mahogany and walnut where building up multiple layers of standard wood finish is ineffective or impractical. Composition Grain fillers generally consist of three basic components; a binder, a bulking agent and a solvent. The binder is wood finish, and in the case of oil-based fillers is typically a blend of oil and varnish. In the case of water-based fillers, it is acrylic or urethane. The type of binder influences the type of solvent used; oil-based fillers usually use mineral spirits, while water-based fillers use water. Both types of filler use silica as a bulking agent as it resists shrinking and swelling in response to changes in temperature and humidity. Other bulking agents may include quartz powder, wood flour, and talc. Use Woodworkers will use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grain Painting
Graining is the practice of imitating wood grain on a non-wood surface, or on relatively undesirable wood surface, in order to give it the appearance of a rare or higher quality wood, thereby increase that surface's aesthetic appeal. Graining was common in the 19th century, as people were keen on imitating hard, expensive woods by applying a superficial layer of paint onto soft, inexpensive woods or other hard surfaces. Graining can be accomplished using either rudimentary tools or highly specialized tools. A specialized thick brush used for graining is often called a mottler. Fan brushes, floggers, softening brushes, texture combs and even fingers are used to create various effects. The painting is carried out in layers, with the first layer being a base. Today that is usually done with latex paint in a gold or orange or tan tone, depending on the type of wood the artist is aiming to imitat. A second layer of tempera or thinned paint is applied over the dry base, by means of a spo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Figure (wood)
{{More references, date=March 2012 In wood, figure refers to the appearance of wood, as seen on a longitudinal surface (side-grain): a "figured wood" is not plain. The figure of a particular piece of wood is, in part, due to its grain and, in part, due to the cut, or to innate properties of the wood. A few of the tropical hardwoods, like the rosewoods, may have a unique figure. Types of figure include: angel step, "bear scratches," bird's eye, blister, burl, curl, ribbon curl, dimple, fiddleback, flame, wide flame, "ghost", pin stripe, quilted Quilting is the term given to the process of joining a minimum of three layers of fabric together either through stitching manually using a needle and thread, or mechanically with a sewing machine or specialised longarm quilting system.

Rift Sawing
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. Process Leading to some confusion, the terms "rift sawing" and "quarter sawing" are interchanged between various sources. Radial cut ''Civil Engineering Materials'' describes rift-sawing as a process where boards are cut radially. Thus, the grain is always nearly parallel to the short edge of the board and thus nearly perpendicular to the long edge of the board. This produces stable boards with comparatively thin grain; least susceptible to warping, twisting, or cupping; and hence most valued for products where dimensional stability is critical (e.g. musical instruments, high-end sports equipment). This is similar to the process used to make wood shingles. The word "rift" derives from " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarter-sawn
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. Quarter-sawn boards have greater stability of form and size with less cupping, shrinkage across the width, shake and splitting, and other good qualities. In some woods such as oak, the grain produces a decorative effect which shows a prominent ray fleck, while sapele is likely to produce a ribbon figure. Process When boards are cut from a log, they are usually rip cut along the length (axis) of the log. This can be done in three ways: plain-sawing (most common, also known as flat-sawn, bastard-sawn, through and through, and tangent-sawn), quarter-sawing (less common), or rift sawing (rare). In ...

Flame Maple
Flame maple (tiger maple), also known as ''flamed maple'', ''curly maple'', ''ripple maple'', ''fiddleback'' or ''tiger stripe'', is a feature of maple in which the growth of the wood fibers is distorted in an undulating chatoyant pattern, producing wavy lines known as "flames". This effect is often mistakenly said to be part of the grain of the wood; it is more accurately called " figure", as the distortion is perpendicular to the grain direction. Prized for its beautiful appearance, it is used frequently in the manufacturing of fine furniture and musical instruments, such as violins, guitars, and bassoons. During the westward expansion of early settlers and explorers into the lands west of the Appalachian Mountains, curly maple was often used for making the stocks used on Kentucky rifles. Usage in guitars Popularization Flame maple is especially popular in guitars, and has been for decades. Generally, the process includes cutting the maple to shape, forming it if necessary ...
