Gene Wengert, forum moderator Please forgive me when I ask you to repeat yourself, Gene. Most vertically stacked wood is not really vertical, i.e. it is on a slight angle. It seems to me that the larger the angle, the more prone the lumber will be to bowing. Bow is one form of warp. Properly dried wood is just too stiff and too strong to bend easily without adding a considerable amount of weight.
Book shelves stay flat for years unless they're loaded with lots of books.
