Blonde Girl With The Longbow

Because the longbow can be made from a single piece of wood, it can be crafted relatively easily and quickly. Amateur bowyers today can craft a longbow in about ten to twenty hours, while highly skilled bowyers, such as those who produced medieval English longbows, can craft wooden longbows in just a few hours.
One of the simpler longbow designs is known as the self bow. By definition, a self bow is made from a single piece of wood. Truly traditional English longbows are self bows, made from yew wood. The bowstave is cut from the radius of the tree so that the sapwood (on the outside of the tree) becomes the back two thirds and the belly, the remaining one third, is heartwood. Yew sapwood is good only in tension, while the heartwood is good in compression. However, one must make compromises when making a yew longbow, as it is difficult to find perfect unblemished yew. The demand for yew bowstaves was such that by the late 16th century, mature yew trees were almost extinct in northern Europe. In other desirable woods such as Osage orange and mulberry the sapwood is almost useless and is normally removed entirely.
Longbows, because of their narrow limbs and rounded cross-section (which does not spread out stress within the wood as evenly as a flatbow’s rectangular cross section), need to be either less powerful, longer or of more elastic wood than an equivalent flatbow. In Europe the last approach was used, with yew being the wood of choice, because of its high compressive strength, light weight and elasticity. Yew is the only widespread European timber that will make good self longbows, and has been the main wood used in European bows since Neolithic times. More common and cheaper hard woods, like elm, oak, ash, hazel or maple are good for flatbows. A narrow longbow with high draw-weight can be made from these woods, but it is likely to take a permanent bend (known as "set" or "following the string") and would likely be outshot by an equivalent made of yew.
Wooden laminated longbows can be made by gluing together two or more different pieces of wood. Usually this is done to take advantage of the inherent properties of different woods: some woods can better withstand compression while others are better at withstanding tension. Examples include hickory and lemonwood or bamboo and yew longbows: hickory or bamboo is used on the back of the bow (the part facing away from the archer when shooting) and so is in tension, while the belly (the part facing the archer when shooting) is made of lemonwood or yew and undergoes compression (stresses in a bending beam). Traditionally made Japanese yumi are also laminated long bows, made from strips of wood: the core of the bow is bamboo, the back and belly are bamboo or hardwood and hardwood strips are laminated to the bows sides to prevent twisting.
