As I got to the point where I needed to do some additional dimensioning in the sideboard project, I recalled a recent blog post by Glen Huey from Popular Woodworking. He submits that the whole idea of letting wood acclimate to your shop is nothing but hogwash. He suggests there is another force at work, and it has nothing to do with loitering lumber. Well, based on the insanely warped poplar I got when milling up my cabinet partitions, I was willing to listen. Glen insists the key to achieving flat stock nirvana is to remove the same amount of material from both sides of a board. So I put that theory to the test using more stock from that same batch of poplar that produced stock only fit for a Pringles can.
