Man, I feel you on this. I've been using glue for my projects too, and my books have held up for YEARS. It's so ANNOYING when people act like sewing is the only real way. Modern glue is seriously strong, and it makes the process faster. The hate comes from tradition, not actual quality. Your glued books are proof that it works just fine.

Whoa, scary stuff man, glad you fixed it before it got worse. But switching to finer nails isn't always the full fix, the hoof wall might just be too weak for standard nailing. My absolute favorite for thin hooves are those lightweight aluminum nails, they hold without as much strain. You gotta be real careful with your nail placement and angle too, or it'll just crack again. Honestly sometimes skipping nails in a pattern works better than trying to use them all.

Fifty frames is a serious stack. I usually tap out around twenty five, my setup just gets too noisy after that.
