3 months ago I needed to repair the bubbling veneer that I applied years ago. Using the slit, glue and clamp I was pretty much am to get rid of the bubbles. Using a block sand I was able smooth out and then set aside till warmer weather to apply lacquers. About a month ago, looked at it the the top, warped about 1/4" up on the front right corner. I applied a heavy duty clamp and was able to pull it back to about 1/16" Let it sit for about 2 weeks hoping it would deform back. I released the clamp and no change. I redrilled the screw hole to accept a larger screw. Liberally applied wood glue - reclamped, secured larger screw and let dry for couple of days. Removed the clamp and it popped back to about 1/4" warp. Any other ideas?

The answer is that it's dry on the top and slightly more humid underneath hence it shrinks on top and doesn't on the underside so the top curls up. Until you have it flat AND similarly veneered and sealed (lacquered) top and bottom, it will keep moving.

My suggestion is to remove the entire top panel from the sides and renew it before reinstalling.

Hoping there was some other ideas. HATE to reveneer this top again. But once the veneer is gone I can slowly add moisture to try to straighten. The warpage did not occur untill after I sand and removed the veneer finish that was there. Would there be a way to add moisture to just the right corner slowly and let it relax?
Here is a current pic after block sanding a warpage...
Suppose if worst case is to peel back old veneer then I may have nothing to lose by adding a damp cloth to inject some moisture.

Where is this cabinet stored? I'm wondering if environment may have something to do with it as I have a Deforest Crosley set that had a warped side when I first got it, which corrected itself within a year whilst in storage.

I thought maybe it was in a basement, of course if the top was previously exposed to some humidity then the top drying out unevenly might cause it.

Since is warped in the area that I sanded it might have warped due to the exposed area.
