Book excerpt: Excerpt from Volume Loss and Grade Change of Hardwood Lumber During Air-Drying Sawmill Operators are often confronted with the task of estimating lumber output. They know the relationship of log grade and scale to product recovery, and they know the effect of a given log size on the cost of producing that lumber. But once the logs have been sawed and the green lumber stacked on the drying yard, what can they expect in terms of volume and grade when that lumber has air-dried? To answer this question, nearly 782 thousand board feet of hardwood lumber were analyzed for changes in grade and volume between the rough green and rough air-dry conditions. Percent volume of lumber recovered after drying is tabulated by lumber grade and thickness for ten species.
