This paper describes grade sawing procedures for improving lumber grade yield recovery from hardwood factory logs. Basic principles of hardwood lumber grades are applied to simplified sawing procedures to accomplish improved grade recovery. Discussion includes positioning surface defects in relation to opening faces. Special consideration is given to defects such as seams, end splits, and rot as well as sawing sweepy logs. While the head sawyer duties are the primary focus of this paper, edging and trimming considerations are also covered.
