sinew on belly?
What function has the sinew on sides and belly. does it help to keep the bow together ?
I would assume so, but there are very few bow designs that I have seen with sinew on the belly, what kind of bow are you talking about?

just wonder in general
Puzio; In the history of composite bow making there are surprisingly some designs which incorporated sinewing on the belly. Besides making up the back of a horn bow, some bows were wrapped diagonally with sinew to cover nearly the entire bow. If done well this becomes inconspicuous; difficult to recognize.
Crab bows from India as well as other designs were wrapped. I believe that other Persian bows were wrapped.
Wrapping with string is the first step in repairing a working hornbow which is separating but other first class bows were wrapped when first made such as some Korean war bows.

I think it is mainly to reinforce splices or joins that come under frequent stress. Given its light weight, dry sinew is very strong for that purpose.Puzio wrote:

Both crab bows and Persian bows generally had the belly made of parallel strips of horn. The binding would have help reinforce these and provide a base to glue the waterproof coverings these bows needed to protect the many glue edge lines.
I think Adam Karpowicz reported in an article that the sinews in the Indo-Persian bows were longitudinal. This might have been done to reduce the compression effect of the sinew during construction.

Interesting. On those bows it must be impossible to scrape the horn if needed. Or is the diagonally wrapping put on th the bow after stung and tested?
The bows that has wrapping is it just at the fades or on many places at th e limb to.
The last bow i made has no wrapping at all but sinew over the edge and 3-4 mm on the belly and still in one piece. Working right now on a 44" half wood half horn, and i was thinking of just put sinew on the back. and see if it will hold together.

Simone; I would say to follow an original prototype when building a bow. What type of bow are you making?
Stephen's Khotan bow had spiral lashings just at the joints of the wood core. Another bow of the era (c 200AD) had spiraled sinew over the entire bow. And two unusual bows, also of Xinjaing, China, had two complete wrappings of sinew from tip to tip in opposite directions. This obviously inhibited adjustment as another longitudal layer of sinew was added to the back of one of these bows.
Koreanbows, if they are reenforced, would only be reenforced at the lower limb area above the grip, which seems to be their first place of failure.
If, however, you are talking about a Turkish bow it will be hard to find one which is reenforced this way. My caveat is the two bows I found in Uzbekistan this spring which areTturkic bows which are entirely covered in sinew.
There is no one answer. Go traditional. Jack.

The bow im working on now is a tukish bow. and next one as soon i have the picture claer is a mughal bow.
