Had a full sheet of walnut veneer plywood delaminate on me mid-project
I was building a set of upper cabinets for a kitchen in Bend, Oregon, and the 3/4" sheet from my usual supplier just started peeling at the edge when I was routing for the hinges. It was a Friday afternoon, and the install was set for Monday. I had to drive two hours to a different yard in Portland to get a replacement sheet, which set me back a full day. Has anyone else had this happen with a specific supplier, and did you get any kind of credit for the bad sheet?
Man, that "peeling at the edge when routing" part is rough. I've had veneer chip out before, but a full delam sounds like a glue bond failure. Was the sheet from that batch looking okay otherwise, like no bubbles or anything when you first got it? I'm just wondering if it was a one-off bad sheet or if the whole lot was sketchy.
Back in 2010, I bought a whole stack of birch ply from a supplier that had a hidden glue issue. Every single sheet looked perfect until you cut it, then the layers just came apart. It makes me wonder, like drew_grant52 asked, if the problem is in the glue spread or a bad batch from the start. I ended up having to send the whole load back, which was a huge hassle. The supplier swore it was a one-time thing, but I never ordered from them again. You just can't trust material that fails from the inside out like that.
Yeah, that "hidden glue issue" Robin mentioned is so sneaky! I had something similar with some maple ply a few years back. The surface was flawless, but the second I ran a dado, the core just crumbled like stale bread. It makes you paranoid about every sheet now.
