How to Make Strings
The most common bow string is one continuous loop and is most often used for Recurve and Compound bows, where a Flemish twist which is several strings twisted is more common among long bows. Bow strings are easy to manufacture and easy to customize.
To make a bow string you need to decide on the length, this can be done using your existing string as a guide or measuring you bow, for a compound the string and cable length information can generally be found on the limbs, recurve is about4 inches less than the bow length and 3 inches for a long bow.
Then there is the type of string, not all bows can handle performance string so keep that I mind when picking your string. IN addition to the main string you will also need serving string which also comes in a variety of material. Most strings also come in a variety of colour, making it easy to make your bow unique to you.
There are two main jigs that are used for string making the main one and the only actually one that you will need is a bow string jig, we have one available for use for members in the club room at Jarvis oval. The other is a serving jig which make it easier to wrap the serving evenly but is not necessary.
Next is to determine the bow string strand. This will be based on the material you have chosen and the peak bow weight of your bow. Each string material varies on its breaking strain ( the amount of weight one stand can carry), so you need to calculate how many strands you will need to reach the peak bow weight for your bow. This will determine how many strands your bow sting will need.
For example if you bow is 40lbs and your sting materials breaking point is 10lbs you will need 4 times your bows peak weight therefore you need 16 strands. 40lbs x 4 / 10lbs = 16 strands or [bow peak weight]lbs x 4 / [string break strain]lbs = [number of] strands.
Adding more strands than needed will make the string stronger but the arrows slower.
