Wane


The figure below shows a cross section of a 2x4 which illustrates various terms. In particular, wane is the missing part, or the part of the board which may be missing. The remaining part of the face or edge is often call the nail surface. The wane can be divided so part appears on one side and the rest on the other side of the surface as long as the sum of the lnegth of the two regions is less than the allowable wane.

Other terms illustrated are the thickness (the real distance, not the nominal thickness of 2 inches); the width (also different from the nominal width of 4 inches).



Software Note

If we call the length of wood remaining after the wane has been removed the nail surface, then mathematically speaking,the requirement that a board fits is that all four surfaces have at least the nail surface length of wood remaining. Thus (at least mathematically speaking) all the wane could appear on the opposite corners on the board, or could be spread around so some is on all four corners.
