Spiral Grain And Annual Ring Width In Natural Unthinned Stands Of Lodgepole Pine In North America Classic Reprint

Excerpt from Spiral Grain and Annual Ring Width in Natural Unthinned Stands of Lodgepole Pine in North America Lodgepole pine products are said to be cross grained wherever the wood tracheids are not aligned parallel to product longitudinal axis. Cross grain can be caused by grain distortions around knots, by sawing crooked logs, and by sawing, edg ing, or ripping boards so that saw lines are not par allel to tracheid alignment. Logs having crook or pronounced taper, if rotary-cut, will produce cross grained veneer. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
