I found a really nice walnut board at my local hardwood place so I had them resaw it for me. The crappy cel phone pic doesn't do it justice. It had cupped by the time I got it home. I was ready for this though. I wet the concave side, stickered and weighted it for a week. It's still cupped. In fact it didn't flatten any at all. Should I try again and leave it longer? Try something different? Is this top toast? I would really like to salvage this and use it if at all possible.
