What material is artificial sinew made from? I have some from three rivers archery. Is it heavier than other materials like D97 and linen? How much does it stretch compared to B50? I have some and would like to make some bow strings with it.
-
It is either made from nylon or B-50 (or so I've heard). The one I've had for years is nylon.

Nylon or Polyester. Not likely actual B50 polyester but it functions exactly the same for all intents and purposes.
You'll be able to tell quickly by testing for stretch.
-
You can make a string with art. sinew but it is very stretchy, way more than B-50. If you want to make a bow string why not buy bow string making material?
Artn sinew comes in 3 or 4 different sizes.

Yep, as Pat said, a serviceable and safe string can certainly be made from artificial sinew (nylon), but the string will be A LOT stretchier and somewhat heavier than a string made from other, more suitable, materials. I actually killed several deer with selfbows using artificial sinew strings before I was able to get my hands on some more suitable material, so I know it definitely works, but it isn't ideal at all.

Ill have to use it for a tiller rope and buy some D97 then. Thanks!

As I said, check and see what you actually have.

B50 is Dacron, B55 is polyester, and if artificial sinew is nylon, and I don't know that, it will have considerably more stretch than the other two.

From the years and years I used artificial sinew as a string before I was able to get "real" string material, I would estimate that it has at least 10-15% stretch under a moderate load. I'm pretty sure it is nylon. This matches what one would expect out of nylon fishing line. I used to make my strings several inches shorter than they "should" have been and they would fall to brace height within a minute of stringing the bow ;D

Tandy artificial sinew is Polyester.

From the Sinew guide on the net........Imitation sinew, or fake sinew is made from man made fibers such as polypropylene, polyester, and nylon. That ,"and nylon" would be enough for me not to use it as a bow string. Probably the reason Flintnp17 got so much stretch when he used it. Better off with B50,B55,or FF, linen, flax, but that is your call.
-
I used it for years. The Tandy stuff behaves just like B50 but looks a lot better on a wood bow. Easier to work with too since it's well waxed already.
-
I used up the last spool I had. Never tried it as bow string. Was only going by research. Would look better on a wood bow.

My tiller string is from Tandy. I also use it to shoot on a new bow until I get one made. If it has any stretch I can’t tell it. It’s 6 strand, waxed together in pairs and braided.
