Two studies were performed to characterize and control warp in nominal 2- by 4-in. (standard 38- by 89-mm) dimension lumber sawn from small-diameter ponderosa pine trees. One study was conducted at a commercial sawmill with trees harvested in central Arizona. The other study was conducted at the USDA Forest Service, Forest Products Laboratory, Madison, Wisconsin, in small experimental kilns with lumber from trees harvested in central Idaho.
