Book Description
Lumber recovery in sawmilling is determined by a confusing interaction of several variables. Since no two sawmills are alike, the variables that influence lumber recovery are seldom the same from one sawmill to another. This complexity confuses even those with a wide range of knowledge and experience in sawmilling. Knowing the variables that affect lumber recovery in general can unravel the factors present in a specific mill. The purpose of this report is to identify and show how these factors operate in determining lumber recovery. The focus is on how these factors affect volume recovery. Since value recovery is often affected somewhat differently by these factors, the emphasis on volume should be noted and the points made here not taken out of context. (Author).

Book Description
A sample of 130 incense-cedar (Libocedrus decurrens Torr.) trees was selected from the EIdorado National Forest in California. The trees were felled and bucked into 403 woods-length logs and processed through a sawmill cutting Shop and Common grades of lumber. Recovery estimates are shown for woods-length logs based on Scribner board-foot scale and cubic-foot scale. Analysis showed that board-foot recovery ranged from 169 percent for 6-inch logs to 103 percent for 34-inch logs. Cubic-volume recovery of rough green lumber increased from 50 percent to 62 percent for the same range of diameters. Yields of higher quality lumber (Shops and Moulding) increased as log diameter increased. Percentage of Scribner scaled defect was found to be correlated with several measures of product recovery.
