Last week I delivered a 8ft long bar to a night club in Sarasota, they called me this week to say that on the inside of the piece, the “veneer” is coming away/separating from the wood. Now, I haven’t seen the problem for myself yet so I don’t have any better description than that. I’m going back Monday to take a look at it, but I’ve never come across this problem before and I’m not sure I know how to fix it. Anybody have any thoughts?
Here are the specs:
A2 3/4 Cherry Ply
1 coat of sprayed dye (thinned with lacquer thinner 50%) *
1 coat of wiped stain
3 coats of sprayed post conversion lacquer (Scuff sanded between coats)
The finish products are used were all M.L. Campbell – production cabinet quality finishes, but it was the first time I used them. (www.mlcampbell.com)
*I’m thinking this might be the problem? Could the thinner have soaked through and disolved the substrate glue?
Any thoughts much appreciated.

Armor Pocket Hole Jig Model APJ14001
The jig’s primary design feature is that the depth guide on the drill bit is set when you clamp material into the jig, so it is always right for the material thickness (from 1⁄2 in. to 1 1⁄2 in.). A color-coded system of screws tells you which screw length to use for each material thickness. A starter set of screws is included. The jig and screw system work as designed, with the exit holes well centered in material of varying thicknesses.

CrushGrind Pepper Mill Mechanism
Matt Monaco designs his pepper mills to accept the CrushGrind mill mechanism, which he likes because it doesn’t require drilling through the top of the mill’s cap and having hardware exposed on top.

I would say that there's an excellent chance that the veneer is delaminating - or there is a void under the veneer.
A couple of months ago, I made a paint-grade mantle for a customer using 1/2" birch ply. I primed it and left it to dry overnight and the next morning I had some "bubbles". As it turned out, the ply had a fairly large void under the veneer which wrinkled due to the moisture in the primer. I cut away the veneer and filled the void with epoxy then sanded and re-primed. Unfortunately, the repair was still visible in the right light and I wound up having to replace the bad piece of plywood.........a major PITA!!!
Good Luck
