I'm planning on resawing and planing either 4/4 or 5/4 stock down to 1/4" to make boxes.
Every test I've done so far has failed. The stock looks great immediately after prep, but cups and/or twists after sitting overnight. I've been searching through the forums on and off for for a few days trying to find out what I'm doing wrong.
The first thing I found was I need to rough out the stock oversized, let it reacclimate, then mill to final dimensions. That sounds good to me, but I recently had some 13/16" thick hard maple cup and twist overnight after taking only 1/32" off each face. I can only assume it's going to be worse with thinner stock.
The second thing I found was the species of wood makes a difference. For example, I've read that white oak doesn't permit the passage of moisture nearly as well as other species so the internal moisture content could be much greater than the surface moisture content. Therefore, cupping and/or twisting after resawing or planing white oak could be more prevalent. I've only tested with pine, poplar, and maple... and have had issues with each.
The third thing I found was I probably ought to get a moisture meter.
I'm leaning towards making these boxes out of cherry and don't want to waste money because I screw up milling the stock.
Any insight ya'll can provide would be much appreciated.
