I thought I had everything lined up to glue up my 7” times three chest top, of 21-1/4”W X 22-1/4”L X 13/16”T.
I had rough cut/resawed the select pieces of soft maple and let them rest for several weeks before sizing them today for glue-up. Things were working so well that I stopped planing at 13/16” instead of the normal 3/4”, for a beefier look.

I had a dry mock up with crown Up, crown Down, crown UP and it all looked good to go. THEN I started gluing and by the time I had applied the glue to all sides and clamped, I unfortunately had a brain fart and now have a Crown, Crown, Crown panel.
Go figure… 8-(

So far, the cupping is less than 1/16” which is not bad thus far, but my question is:

Which way will this wide soft maple tend to cup in the future?
Am I correct in thinking that the cupping will push the corners “away” from the theoretical trees’ center? In other words, Crowns up and pull down the sides/corners?

NOTE: The only anchor points for holding the top onto the chest are basically near the four corners ONLY. Two countersunk slots in the back and two countersunk holes in the front. There is no provision for center point anchors and too difficult for 7” drawers (space) to install.
