Lumber

Board lumber comes in many different sizes, types and shapes. Most of the lumber we use in set building is taken from fast growing soft wood trees. We must do our best to recycle as much lumber as we can. While wood does grow on (in) trees, we should do our part in preserving our natural resources. We use the following sizes of board lumber the most. You’ll notice that the list has two different columns on the left. One labeled Name and the other labeled Actual. A 2″x4″ is not actually 2 inches by 4 inches when it reaches the lumber yard. You see, when the wood is cut from the log at the saw mill, the actual size is 2 inches by 4 inches “rough cut”. Rough cut means the surface of the wood has rough saw marks all over it. When you get the lumber, it has already been smoothed via a large wood surface planer. When you pass wood through a surface planer, the blades take off 1/8th of an inch from each side. The result is a smooth piece of wood that is smaller then it’s name.

The Actual dimensions may vary from wood to wood. You should always double check the actual size before finalizing your cut lists. Let’s say your cut list calls for 1×3 to be cut to 3’7″ for the toggle of a 4×8 flat… If the 1×3 were to be 2 3/8ths instead of 2 1/2″, the flat would be just a bit narrow.
