What is the difference between a bow and a crest in a piece of lumber in construction?
It's a warping of the board... right? I just don't know which goes to the short side of the board and which to the wide side.
When looking down the length of a board with the thinner edge on the horizontal plane, and the wider edge on the vertical plane, bow is an arch from left to right or right to left is a BOW. If the board in the same position, if the board rises or falls in the center that is a CROWN. (Not a CREST)
