A wonderful collage of images to both demonstrate your lessons and remember the experience by. Building a bow is not the easiest task.
Is that photo of a cleanly snapped bow the outcome of your efforts? Tragic, to be sure, but not a game-ender. The break (if that's what it is) can be splinted/spliced from the belly and be good as new......if not even better. A good treatment of sinew backing/wrapping and hide glue in layers over your repair will make the break a distant memory.
Fun pictures and thanks so much for sharing. Looks like a blast. Great job.
