boards from repeated wetting. This method was known as "Ricking." Ends were coated with a paint or other non-porous material to prevent the ends from drying faster, a condition that created splits, commonly called checks. Air-drying may require anywhere from 15 to 200 days of warm, not too humid weather in order to reach a 15% MC for 1 inch thick material, such as pine. Later, wood must still be dried for a time indoors before the lumber can actually be used for cabinetwork. This whole process may take a year or more.

Today, most lumber is kiln-dried. This is a thermostatically controlled process of water removal in specially constructed kilns. Temperatures range anywhere from 110 to 210 degrees Fahrenheit. The advantage of the commercial kiln is that wood can be dried in a very short time.

Many a woodworker is tempted to take a locai tree, most likely walnut, have it brought home, cut into boards, and stacked outside, with the intention that it will be made into fine pieces of furniture. If he can get the tree's sections moved and if he can find a sawmill that will accommodate the logs, air-drying is still a process that takes knowledge, care, and patience. A useful government booklet on the subject is Air Drying of Lumber: A Guide to Industry Practices, U.S.D.A, Agricultural Handbook no. 402, U.S. Government Printing Office, Washington, D.C.20402.

Cutting the Lumber

Rarely is a tree section dried in its entirety. It would probably not dry evenly, whether air or kiln-dried, and the process would take too long, especially with air-drying. The rule for air-drying is: one year for every inch of thickness. Because of these problems, then, logs must be sawn into boards before the wood is actually dried.

The typical commercially available board is either plainsawn or flatsawn. With this method, four slabs are first cut from a log to remove most of the bark and some perimeter sapwood. The squared log is then sliced into boards. With plain or flatsawn boards, when looking at the end grain, you will note that the curvature of the annual growth rings often runs roughly parallel to the surface (see Fig. 2).

Another type of board cut is known as quartersawn. It is called this because the log is sawn into quarters and the boards are then cut so that the rings are nearly perpendicular to the
