I made a thick table top out of 4×4’s last summer. sat in the garage for a about a year. Finally got around to doing something with it. The problem is it warped/twisted about 1/2” over the year. I hand planed it as best as i could. I ended up cutting a bunch of relief cuts about 3” into the wood. sat over night outside on my balcony and it seems to have gotten better. should I leave it out longer? or is there something else i can do? It is supposed to rain in the next day or so too. I’m just trying to avoid it getting worse than what it is. Thanks!!

Hi, sorry you’re having trouble with your table.

4X4’s may be a bit much for a tabletop. One issue in particular is the trim board on the end. Unless that allows the boards to expand and contract, it will cause significant issues such as warping or cracking.

For boards attached across the width of a table, they need to be built like a breadboard end. A well-made breadboard end is pinned in the center, but allows the table to freely expand and contract.

Best of luck.

Changes in humidity can be a big problem for outside furniture. In Wisconsin it must go from “0” in the winter to 90% or more in the summer. That is why picnic tables have spaces between the boards and no end caps.
Correct it as best you can and learn to live with it under those conditions.

Thanks for the replies guys… the table itself was assembled with biscuits made from 1×3’s. The boards one the sides are just glued with some finishing nails I’ll pull those off and see how the table behaves. Was going to use the table in the garage but my fiancé wanted a small table in the entry way of the house… figured since I already had the top I would use it.
Thanks again
