So the top of my table has warped... I recently moved it, but don't remember it having this problem. It is less apparent when the leaves are in. When they are pulled out, the cupping is obvious and it wobbles back and forth, always with a high corner.I wet the underside and laid it down with a bunch of heavy dictionaries on the corners. Not really sure how to proceed? What would you guys do.
I'm sure it is annoying, mgee. You mentioned having moved the table. The floor in its present location may be closer to level than that which the table had settled onto.
You also mentioned "cupping" of the top. I assume the tops on these are veneered particle board which typically remains stable and close to flat unless exposed to moisture or extreme humidity. Unlike solid wood, composite wood-product panels like particle board, MDF, and even some plywood won't recover after expanding. It's possible that wetting the underside of your top may have made things worse.
Is there actual deflection that you can see or measure by placing a long straight edge across the top? Sometimes, slight twisting or "wind" may be hard to see or measure. Placing two straight pieces of wood along both ends and sighting across them can help to detect any.
