Book Description
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.

Book Description
Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

Book Description
The USDA Forest Service standard grades for hardwood factory lumber logs are described, and lumber grade yields for 16 species and 2 species groups are presented by log grade and log diameter. The grades enable foresters, log buyers, and log sellers to select and grade those logs suitable for conversion into standard factory grade lumber. By using the appropriate lumber grade yields, log buyers and sellers can appraise the logs in terms of expected lumber grade volume and value.
