This build has been on hold for a couple weeks, mainly because I've been focusing on other projects, but also because after re sawing the ziricote into the two pieces to be book matched for the top, I left them for about a week, then found that they had developed a bit of a cup. I left them to see if the cup would go away naturally, which it has not. I have been debating if I should 1) attempt to bend the cup out by leaving pressure applied; 2) try planing the cup out of it; or 3) leave the cup, and hope the clamping pressure and glue are enough to keep it flat when glued onto the body. However, I just had a brain wave this afternoon, but want to see if I understand this correctly before I get my hopes up. First, I know that the cup can be caused by differing moisture contents on sides of the board. As seen in the previous pictures, this board came to me with a pretty good layer of finish on it. After cutting the board in half, each half developed a cup with the unfinished side forming the concave side. So the questions: 1) first, am I correct that the concave side of the cup would be the half that is more dry? And 2) does it follow that the finish on one side is preventing that side from drying at the same rate, and so, removing the finish could cause the cup to correct itself? If not, how would you suggest I proceed with this? Thanks!
