Download or read book Lumber Grade Yields for Sub-factory Class Red Oak Logs written by James G. Schroeder and published by . This book was released on 1968 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2If we are to meet the increasing demand for lumber through more intensive forest management and increased utilization, we must find ways to economically process the low-grade segment of our sawtimber resource. We now have little or no information about the conversion value of sub-factory class sawlogs. The study reported here is the first step in determining the value of the sub-factory class of red oak sawlogs. If we assume similar red oak yields for any particular area of operation, the results reported should enable a sawmill operator to determine the marginal log for his particular operation if he knows his costs for converting these logs into factory-grade lumber.
