ABSTRACT:
Methods for optimizing lumber are provided. In an embodiment, boards cut from a log are examined for warp stability and/or knots. This occurs prior to and/or after the planing process. Based on the examination for warp stability and/or knots, the boards can be sent to a lumber upgrade process, such as for example, re-drying, edging, splitting, trimming, chopping, chipping, or the like. Accordingly, the method of the present invention enables more efficient allocation of lumber towards manufacturing needs.
