Need advice please,

Building a small coffee table out of some ambrosia maple I picked up.
I cut the boards to 42” length and ran the boards through the joiner.
On one of my wider boards the 2 ends line up flat with the other boards, but in the middle there is a bow of about 1/4”. I plan to join the boards using biscuits and glue.

Options I am considering:
1) I can easily press the bow out and glue up the boards, but my fear is over time the tension will weaken the joint and it will spring back.
2) I thought about wetting the board and placing weights on it to try to straighten out, but not sure if that’s viable.
3) Buy a new board (Really don’t want to go this way)

Are there other options.
What do you think??
Thanks in advance for your help.

” I cut the boards to 42” length and ran the boards through the joiner”.

Do you mean planer? If you use a jointer correctly the board should be flat with no bows.

If your boards can be pushed into alignment with moderate hand pressure, you’re fine. The glue will be strong enough to maintain that alignment once cured.

Use cauls to keep everything aligned during glue-up (IIWM—I’d skip the biscuits, they only complicate the glue-up without helping structurally), and appropriate attachment system to attach to the table base

I ran just the edges across the joiner, not the flat part. I only have a small table top joiner. Its ok for edges on shorter boards, but no way could I get the bow out of this board with it. Unfortunately I do not have a planer yet but I do have a drum sander that I will use after the glue up and basic hand planning
