In one of the TBB's I saw a picture of a silk cordage bamboo bow and now I cannot find it. I know Dick Baugh made A Cordage Backed Bow
by using nylon cord. I have wondered about kevlar or high test braided fishing line. I have too many projects to start another so this is just a what if question?
-
The braided fishing line is something I use a lot when I fish and it has no stretch. I think the silk stretches some which is what you want at least from my understanding of it. I could be completely wrong. The fishing line doesn't stretch at all though. Mono fishing line stretches alot.
-
The idea I to have some stretch. Even those no stretch fishing lines do stretch somewhat. You'd have to drop the strand count or poundage of test to find the right balance.
-
I think silk has stretch and some spring back is why it is used, I don't know if those materials stretch and return but if nylon would work then I suppose those materials would work. If you google silk roving you get a material that you could make cordage of to get what you need. I'll be watching this, sounds interesting!
-
What about tennis racquet string? Natural cow gut string has the most elasticity when compared to synthetic tennis string. The synthetics include nylon, poly/kevlar mix, and mono filament.
I would say sinew would have even more elasticity than cow gut.
-
If I remember correctly, the silk was pre-stretched and the stretch came from the twist. I wish I could find the picture in the TBB. Silk and boo would be a natural together. With a silk bow string too.

TBB1 p 110 is probably what you're looking for.

A few years back I made an Aleut style flat bow and used artificial sinew for the cordage, 8 strands I believe. The cordage added several pounds. After several hundred shots a crack developed coming off the handle. It was a worthwhile project.

That is it! Thanks!
