The modern material of choice is a waxed polyester string: Dacron B-50. It comes in large spools and is about the diameter of thick dental floss. Depending on the strength of the bow, you will want to use 12-16 strands of Dacron B-50.
An arrow usually consists of a shaft with an arrowhead attached to the front end, with fletchings and a nock at the other. Modern arrows are usually made from carbon fibre, aluminum, fiberglass, and wood shafts.
Cut a notch in one end of a 2×4 for the bow’s handle, and notches every 2 inches along the board’s edge to hold the string. Bend the bow to your desired draw weight a few times after each shaving session. After several repetitions, the bow will eventually reach your draw length.
Putting in twists will make the string effectively shorter (think about twisting up a piece of string) which will increase the brace height; taking twists out will effectively give you a longer string and therefore smaller brace height. To do the tuning – start with the lowest sensible brace height and shoot 3 arrows.
The most commonly used number of strands is 12 strand B50 string , which provides a balance between size, weight, strength, and nock fit. Bigger 14 strand B50 strings are mostly used on heavier bows as well as where the extra weight of the bowstring acts as a slight damper to make shooting more consistent.
Choose the Right Wood
Some of the best wood for making bows include Osage orange, yew, ash, black locust, and hickory; most hardwoods (like oak and maple) will work.
Woods are various, but currently the most common is pine. Port Orford cedar is a traditional favourite; it is lighter and holds its straightness better than pine. Good shafts in this material are however more difficult to get hold of. Other woods are used such as; ash, birch, poplar, hazel, beach, and oak.
The steel is an anomaly, but its design and form are not. The bow is a reflex bow, meaning that it is bent away from the shooter when unstrung. … Metal bows themselves are not uncommon.
Pine is NOT a good bow wood, however, any wood can be a “bow wood” if the design fits the properties of the specific wood. For Pine I recommend very wide, I mean three or four inches. Be sure to back it with a heavy linen or silk cloth as well.
A good hard wood works great for homemade bows. Red Oak, Maple, Black Walnut, Hickory, Osage Orange, Ipe, Ash, Yew, etc. all work well for bows. … While you could still make a bow that had those in it, the strength of the bow would be severely weakened and it is liable to break on you.
Not just any hickory or bois d’ark tree will work for bow-making. … With the “green wood” technique, the bow is roughed out to near its final shape, and then allowed to quickly dry under controlled conditions that prevent it from warping. The fine-shaping of the bow is done only after the wood has become dry and hard.
