So i got this little surprise when I stripped one of a set of eight Wishbone chairs to redo. I had no idea it was there; the chair didn't feel wobbly at all, but I also didn't put any pressure on the paper cord seat. If I had, I probably would have noticed that sagged more than it should.
Anyway, I slathered it with Titebond and clamped the heck out of it and now it's nearly impossible to see where the crack was. My question: do I need to reinforce it any further? I don't think the glue bond will ever fail but I'm worried that it will crack again along the same grain line. The chairs are 40 years old (soap finish!) but the owner says they've never had daily use. Or maybe she meant they no longer have daily use. I just know I don't want there to be any risk of this happening again on this one.
