Help-Warped cutting board

I think I know your answer will be no but I will be stupid and ask the question anyway!
Did it get wet?
BTW! I love the board!

Harvey, no

I make and sell quite a few end grain boards and tell customers water is the enemy! LOL! Hope you weren’t offended? The only thing though that otherwise cones to mind is the squareness of the ts? Or, perhaps one wood had a significantly higher moisture content?

Harvey, I certainly was not offended. I appreciate your input.

Hopefully you can lay it out on a flat surface and have it return close to flat! Sanding those things is a pain IMO!!!!

Let it dry and equalize the moisture content between the woods. Then flatten with a drum sander or router jig. Working with a piece that has recently been glued up can still have an elevated moisture content even though the glue joints are dry enough to machine.
Clamping cauls will give you a better alignment across the strips but they can trap glue and moisture underneath them as well.

“The non-planar design allows liquids to drain predictably off the cutting board and out of the cook’s way.”

I have seen cuttingboards cup because of uneven mineral oil application. Like putting 5 coats on one side and 2 on the other. They usually even out, if not it may be fixable by giving more coats to the cupped (concave) side.

Try putting four small feet on it one in each corner to let the air go around it and breath a bit it seems to work with the ones I made. Cheers dunk

Thanks everyone for your input.

GeBeWubya, I like the way you think. Wouldn’t have to worry about liquids puddling up on the board.

If it is cupped on all sides, then turn it opposite of the convex and see if airflow/ heat from the sun cause it to self-correct.

An educated guess is that there was a notable moisture differential between the stock used. I have experienced a similar issue in the past. To prevent this I have had to bake strips in the oven at around 120 deg for about 45 min. For me that had balanced out the moisture content in most of the stock (air dried} that I have used. I also use hot mineral oil/beeswax mix to cure the completed cutting boards. I have found that the this technique penetrates better and greatly adds to the water resistance… adding a little beeswax to the mix helps the oils from being stripped out of the boards when washing. And bless her heart has also survived a few trips through the dishwasher.(not recommended)
