Houston, we have a problem. I thickness planed this cherry a few weeks ago and put it under my bed till I had the chance to turn them into a table top. Well I now notice that a couple of boards have slightly bowed. Here is a pic of one bowed board against a straight board and then me applying slight pressure in the middle to flush the two boards together. I’m afraid that after I edge glue them the one board will eventually bow back.

I was thinking that I could use a sliding dovetail across the middle of the boards to act as a straightener to resist the bowing but I’d hate for it not to work and for it to just make the problem worse.

What do y’all think? Sorry if the pics are sideways I am having to upload them from my phone.

Are those edge boards edge jointed and ready to be glued? I would think that you can glue them up and they will then function as a unit. Assuming that this table will have aprons these will help keep the top straight.

I’ll wait to hear from others, but I certainly believe the use of biscuit joints or dowels in the joints will aid in preventing further bowing. Have the boards acclimated to the humidity that you plan to construct the top or the place where it’ll be located after completion? That’ll make a difference.

If you can spring them back that easy, glue them up. The ones that are bowed should be reversed so they work against each other.

That’s pretty minor.

Like Don suggested….alternate the growth rings and glue them up.

Thanks for the advice, guys. The bow is fairly small and is easily corrected with little force so I may just edge glue it up and wait a few says before I continue building the frame. If it remains flush then I’ll continue, if not I’ll probably redo it using dowels like was recommended by Handtooler.
