I used TB3 and clamped it with bike tire inner tubes. Not the best glue for what I'm doing with it, but I'm hoping I'll have enough contact surface to hold. Once I clean it up if it doesn't look good I'll take it apart and get some good epoxy. Right now it looks like it's good a good enough glue line that with some decorative wrapping Itll hold up fine. I plan to cover the sinew with carp skin and will thread wrap the seam. So might as well make the thread pull triple duty. Hold/cover the sinew skin edge, hold the lever together, and be decorative.
