Well I made a mistake and glued up all with the same grain direction. This is 1.5” walnut. Was flat for a few weeks then garage flooded and humidity went way up and now it’s cupped across the piece. About 3/8” pronounced in the middle.
what can I do to fix?
i have a sliding table saw, 16” jointer, and a 22/44 drum sander.
the piece is in the long grain direction 48” and across 39.5”
would really appreciate thoughts here.
