My glue-up method was wrong for years and I only found out at a library sale
I was looking at a rebound copy of 'The Old Man and the Sea' at our local library's annual sale. The spine was perfect, no cracking at all after years. I asked the volunteer how they did it, and she said they used a cold PVA mix and let it set for a full 24 hours before casing in. I had been using a warm mix and rushing it in 6 hours, which explained why my older projects always got stiff. Has anyone else switched to a longer cold set time and seen better results?

Honestly, I've had the opposite experience. I stick with a warm PVA mix and a quick clamp time, maybe 8 hours tops. My stuff holds up fine and I've never had a spine crack. Waiting a full day just kills my workflow, I'd never get anything done. Sometimes the old fast way works if you do it right.

Oh man, that's hilarious. You were basically speed-running your glue and wondering why it got brittle. I guess the library isn't just for books, it's for free workshop fixes too.

Yeah the "old fast way works" thing got me too. Used to rush every glue job thinking time was money. Then I fixed a hundred year old chair that had been glued slow with hide glue. That joint outlasted every quick repair I ever did. Changed my whole view on curing times. Now I just plan for the dry time and work on something else. The wait feels worth it when things don't fail later.
