I have several boards of 8/4 oak that is 12-16" wide that have a severe cup. It is probable 3/4-1". Is there a way to fix this? Is my best option to rip it down the center of the cup and then surface the wood.

I bought the wood several years ago and it has been in my shop. It originally had a little cupping to it but it has gotten worse. I did have it stacked in my shop, and yes it was stickered. I never did rotate it. Was that a contributing factor?

Any ideas would be helpful.

Thanks
