Hi Folks,

I recently completed a cutting board which will pull out from a slot in the
kitchen cabinets just below the the level of the counter top.

I made the project using hard birdseye maple boards edge glued and buiscuit
joined. It's dimensions are 29 3/4in x 24 1/4in x 3/4in.

I am finishing it by applying many coats of mineral oil.

The problem is that it appears to be wildly unstable. After first glueing
up but before applying any oil, I left it alone for a week or two, the end
result being that it was severely cupped in the center. I wet the surface
with water placed it on a flat table with a weight in the center and it
again became flat. After apply several coats of oil I was hoping it would
be more stable and left it again without a weight but it cupped again. I
have reapplied the weight and it is straightening out again but my fear is
that once installed it will begin to cup again and will not slide freely,
or may even get stuck in place.

What should I do? Is there a way for me to permanantly stabilize this
board?

Thanks,
Joe
