Did it cup while on top of your car? If it did it was the sun drying the top
side by shrinking the surface. Try dampening the back side and put it in the
sun for a couple of hours with the other side facing the sun, watch it
carefully it may uncup. Then clamp some heavy boards on it to keep it flat
and get it out of the sun and store it for a few weeks while clamped. It
should stabilize - we hope.

Hi All -
I bought a wooden countertop at a high-end cabinet shop's yearly yard
sale last summer. It's 90"L x 25"W x 1.5" thick. I brought it home on
the top of my jeep, and it cupped. Good side up, the cup is center up
along the length about 3/8 inch, over 1/3 of the length from the left
edge. It did not settle over the past year.
The edges are doubled 3/4 inch boards, and the field is 3/4 inch also.
I'm condsidering kerfing the underside to flatten to the top. My start
would be 3/4 or maybe 7/8 inch deep kerfs thru the doubled boards on the
affected end, probably at 1/2 inch spacing.
It's destined for the workbench, and the investment was $40, so I can
experiment.
I saw Norm do this with a burned board on an end-table in the NYW, but I
swear he broke it by the sound of the crack.
How deep would you go, and how often would you do it? Or, what would you
do otherwise?
Thanks in advance.
...best, Capt N.
