Drying timber is one method of adding value to sawn products from the primary wood processing industries. According to the Australian Forest and Wood Products Research and Development Corporation (FWPRDC), green sawn hardwood, which is sold at about $350 per cubic metre or less, increases in value to $2,000 per cubic metre or more with drying ...
Flat-sawn wood often exhibits "flat-" or "slash grain", where the angle between the visible growth rings and the width of the board is 45° or less. [4] This makes the wood vulnerable to deformation as it dries, or if later exposed to moisture.
Diagonal- and stepped-cut rift-sawing is intermediate to flat-sawn and radial cut lumber. The angle of the bastard grain may differ along the width of the board or between opposing sides, and enhances the appearance of ray fleck. Flat-sawing is the quickest method, producing the least wood waste and largest possible boards from a log.
