That is interesting. So the sinew is taking the strain off the wood and so long as the poundage is low enough, the compression in the wood won't merit applying horn? I would be interested in trying this with mulberry if you believe it would hold up. I have a lot of it where I live and have been wanting to try a horn-bow for quite some time, but haven't found any water buffalo horns in my area that are long enough, so have been holding off. I've got better compression woods, namely incense cedar and chinese juniper, but both have torn up the back when the sinew I applied dried. I mean literally tore the back right off in areas. Thought about the whole carbonized bamboo thing, but would rather use wood if possible.
