Old thread, but because of the short time it takes to build one of his horse bow designs, and the end results of it's performance it is worth renewing.I have built a dozen or, so of them all modified. His design always seems to shoot harder than mine. He uses top line tempered bamboo, and longer ,sharper siyahs. I have made a few of these bows with bamboo floor boards that do OK over all. Simple, and efficient design to make for beginning bow builders while their wood is seasoning etc.
