OK, here it is. It's a rocky mountain juniper recurve, backed with bison sinew. Got the sinew on last weekend. It was my first experience sinewing a bow, and it looks like it--not nearly as smooth and pretty as I would like. But I'm pretty sure it worked.
Now I have to wait several weeks to it to dry, shrink, pull the whole thing into a bit of reflex, and otherwise work its sinewy magic. In the mean time, I plan to put on some bison hoof tip overlays, try to find a nice bull snake skin (or a couple rattlesnake skins) to cover and waterproof it, and think happy thoughts.
