Tonight's question is how much can a hardwood book shelf be expected to expand or contract with the seasons?
I understand that a) it depends on the wood and b) it depends on the orientation that it's cut but I just want to get an idea. If a shelf is 30" X 11" how much might it change across the grain? 1/4"? 1/2"? 1/8"? It's pretty damp here all year round.
