Re: wood panel cupping

Mount it where it belongs, holding it tightly to the stretchers. Remember to put as many coats of finish below as above so you don't get unequal moisture adjustment, which is what you'll get ( or may have already ) if you lay it on a flat surface and leave it through a bunch of damp days.

Hi Chris, If you have let it sit on a table for a day or so with only the top exposed to the air then just flip it over for a day or so so that the other side can absorb or lose the moisture the first side gained or lost. If that is not the case I would first check your jointer to make certain that the fence is set to 90*. If the fence is not at 90 then you will be starting with a curved piece unless you flip every other board 180* end to end. ie the first edge is 88 while the mating edge is 92 so you have a flat surface. Now if that is not your problem, then we get into the contentious issue of gluing up "wide" (more than 3 or 4") boards. Wood has a tendency to cure toward the bark side as it dries / seasons. That is why many people will only use narrow boards and alternate the grow rings on adjacent boards. If you have used 8" boards that have not been completely seasoned then you problem will likely just get worse unless you rip the boards into smaller pieces and flip ever other piece. Hope this is of some help. JG

Use sliding dovetails on the underside, both to hold it flat and to join the top to the base.
