Just got a Black Hole project in a trade for another project I was stalled on. There is a large separation in the rear corner of the cabinet. The plywood has separated where the central channel was. The outer layers of the plywood seem to be a little warped outward. I can press them back together with my hand but I’m concerned if I glue it all back together either the plywood warped it will just crack and separate again down the road. Any opinions?
