I didn't remove the paper from the foamcore, some in some sense it's basswood-paper-foam-paper-basswood.

It's bowed so the middle arches away from the side against the rail during clamping. So the outer side is effectively slightly longer than the side against the rail. I'm wondering if I ran into some differential drying issue - the outer side drier faster?

I switched to laminating wing cores while I ponder the next step. For the wing cores, I'm using BSI 30 min epoxy and vacuum bagging - doing the bottom in one pass and the top in another. I left the paper on the lower side of the wing to help stabilize it - I find the foam warps all over if I take off both sides.

So far, they are behaving.
