Hi friends,
I’ve been reading the PA forum for a long time but I never had the opportunity to post some of the things that I’ve made.
Now, two weeks ago I asked questions about how to make a sinew bowstring
http://www.primitivearcher.com/smf/index.php/topic,3084.0.html. So, I’ve been working on it since then, have been doing some exercise and lots of testing. Today, I shot my first two bowstrings. Here are some pics.
1. One of my first finger loop braided sinew sample string with 25# weight on one end for testing. I left this string outside during the night to test-pull it the following morning. Result: no problem.
2. Another test string after pulling it: bad splice.
3. Long bowstring: test-pulled 70 times to 90-100# without problem. Shot in today 50 times from a 50# longbow. This is a small diameter “below” 1/8” sinew bow string. No noticeable difference in arrow speed compared to a 14 strand Dacron B50.
4. Long bowstring: test-pulled 30 times to 90-100# without problem. Shot in today 30 times from a 50# longbow. This is a bigger diameter “around” 1/6” sinew bow string. Arrow speed seems to be a bit slower than a 14 strand Dacron B50. The sinew repeatedly slapped against my bow arm which has a big red spot now just in front of the thumb
5. Bowyers knot on bow scale, thick string.
6. Ear, thick bow string
7. I was shooting in bad weather today

9. Bowyers knot on bow nock.
9. Ear on bow nock.
Thanks once more for your help and thanks for looking.
PS: Any comments or suggestions for improving things are welcome (Ex.: I’m not very happy with the bowyers knot on a sinew bow string)
