Topic tags/keywords: question pine table top edge glue up battons

I am building a coffee table for my wife and she wants the top to be 3 wide boards (the top will be 32” wide). I am using 2×12 SYP joist for the top (it is the look she wanted).

After planing 1/8” off each side of the boards and letting them sit in the shop over night they cupped. I brought them back in the house where they have been stickered for months and the moisture meter had moisture content down to 7-8%.

Would it make sense to add battons (even if temporary) at glue up to prevent them from cupping again if I plane out the new cup. I figured I would do breadboards and possible a couple of battons for the final piece.

My wife really wants the wide boards and as patient as she has been on getting the shop set up I would really like to deliver. Are there better alternatives?

Thanks in advance.

Battens won’t prevent cupping, it’s a hydraulic action, something will give. If it were me I would plunge ahead. I think you’ve waited long enough and done the right things. Generally you cut to rough length, flatten one face, true one edge, sticker overnight, and repeat in the morning. 24 hours after glue up you will probably need to flatten the top again with a hand plane, not a bid deal. Someone will tell you to alternate the grain but that’s a myth, it doesn’t prevent cupping either.
