Hi All,
So I’m building a farm table for a customer.
This customer wants rustic. I was not able to talk him into breadboard ends, which would make me feel good.

The lumber used was pre-planed 7/8” kiln dried, three 10” boards for the top. They were slightly funky when I got them but I was able to achieve a fairly flat and very tight glue up (jointed/ripped edges of course).

What happened was two of the boards cupped causing cracks right in the center on the ends, about 8” in.
Before cutting it to final length I wedged the cracks open a bit, filled with clue and clamped using cauls.
One of them it fixed beautifully but the board in the center which was more cupped, sprung right open.

It’s a miniscule check, about 4” long. When I press the board flat it is virtually invisible.

But I’m concerned it won’t stay up.

I had the thought to basically rip 1/8” out of the center of the top, eliminating the crack, and glue it back together semi seamlessly.

Or, what do you guys recommend? Epoxy slurry? Leave it alone and hope it stays put when I screw the top down and it gets pulled flat?


I made the bad mistake of rushing this lumber (not acclimating it), mostly because I had no choice as customer needed it by Christmas Evve. But never again will I make a table without rough sawn lumber jointed and planed perfectly flat.

Thanks guys for any suggestions!

Wound up ripping the table to cut out the crack. Gave me the additional advantage of being able to run both halves over the jointer to get nice and flat (but still not parallel).

Seems to be “fixed.”
