A very nice bow!
You should chrono this one. And do you have a image of the problematic knot? How much it took set? Is black locust native there or imported wood?
Will chrono this one if the weather clears up a bit, no set yet but has only about 200 arrows throught it. On the other hand, it’s sister stave is a 66” long hld recurve drawing 60@28 and has no set after a few thousand shots.
Black locust grows around here and I have great success with heat treating in combination with a hollow belly.
