Blonde Girl With The Longbow

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.
Today, good laminated longbows may be made of wood or can be purchased commercially. Any wooden bow must have gentle treatment and be protected from excessive damp or dryness. Wooden bows may shoot as well as fiberglass, but they are more easily dented or broken by abuse. Bows made of modern materials can be left strung for longer amounts of time than wood bows. Wooden bows should be unstrung immediately after use to avoid large amounts of set.
