How to bake a,tree. Andwhy
he tougher your woodproduct application, the more you rely on the properties of properly seasoned wood-its lighter weight, resistance to decay, improved machinability, enhanced dimensional stability, and uniform acceptance of paints and stains. Chances are, you take these qualities for granted.ltrThether you know it or not, drying green lumber to perfection takes some pretty sophisticated cookware, the right recipe, and a gourmet touch.
Kilns a la Carte.
The historical menu of wood-seasoning recipes is quite extensive. The first and simplest method, uncontrolled air drying, proved to be a slow, uneven process-often resulting in excessive waste due to splitting, checking, and warping of the wood.
Early attempts to dry wood with hot air were imaginative, but a bit disappointing. Lumber was placed in a room through which was passed the smoke of a roaring fire. The wood dried quickly, but also checked, warped, and charred. Early lumbermen believed that having plenty of seasoned wood on hand outweighed their losses due to "overcooking."
Oven-like kilns were patented around the time of the Civil \Var. These units incorporated vents to discharge the moisture released from the wood, and inlets to allow fresh air to enter and circulate around the lumber. These basic design elements can still be found in todav's forced-air. controlledhumidity dry kilns.
"Pans is parts." Or are they?
Even with today's automated kilns, seasoning lumber is far from foolproof. As you might expect, there's a slightly differ ent drying "recipe" to accommodate the different moisture characteristics of each wood species. That's the easy part. Because even within a species, no two logs have identical moisture characteristics. And the wood within a single tree will have pockets of greater and lesser moisture
