Oak Dining Table swelled and shrunk in storage.

If the cracks go all the way through use a shop vac on the underside to suck the glue through. Apply copiously, suck through, clamp overnight, and clean up (scrape off). If not all the way through, use a thin ca glue and clamp.

You will never get those creack to close up, even in a normal living space there are changes in temp and humidity…..they will just open up agian.

Steve, sounds right….about a year ago I heard about using the vac to pull
glue thru the wood. If you have to fill the crack with a filler, GF has some
gel stains real close to that color….Good Luck!!!!

Just leave it alone. It will acclimate and either the cracks will close up
or they won’t. You can fill them with wax or shellac burn-in sticks if
you like. You can also rip and re-joint if you’re just plain crazy and the
thing bothers you. There is a school of thought that it is best to
“hollow” joint boards so the ends are pulled together by mechanical
advantage. The theory is the joint will be more resistant to separation
due to the increased pressure at the ends.

i would leave it in the enviroment that you want to keep it for a few weeks and see if the wood gains an equilibrium . my guess is the cracks will either close if it takes on moisture or will open more if enviroment is dry. then i would fill with epoxy and refinish. you could also mix some sawdust with the epoxy to get some colour into the cracks

-- just get stuck in and have a go!!!

The epoxy is the only appropriate easily-got choice here. Yellow glue won’t stick to glue residue, so your fix wouldn’t work with it, even if the boards wanted to go back together. But they don’t.

Any of the radical repairs suggested—recutting, epoxy namely—will supplant your current concerns with finishing issues.

The quick way out: soft putty and live with it until it tells you something new.

The Mr. Detail way: recut and rejoint and reglue and strip and resand and deal with the finishing left to do.

The cracks can not be treated by squeezing the wood as you have in the pictures.
I would open them up with a saw and fill them with little splices..

One of the facts about cracks is that they go further than you can tell by looking at them. The crack probably extends an inch or three past the apparent end of the crack.

I had this happen to butcher block. There is really only one way to address it. Just accept that the wood had found a new shape and work with that.
