Book excerpt: Excerpt from Lumber Recovery From Old-Growth Coast Douglas-Fir The volume of commercial Coast Douglas-fir sawtimber is estimated to be in excess of 394 billion board feet. About 10 billion board feet of Coast Douglas fir is harvested annually. This is about 55 percent of the total softwood lumber production in the United States. There is an urgent need for better methods of appraising the quality of this important timber resource. Estimates of the recovery that can be obtained from Coast Douglas-fir sawtimber are needed by forest land managers, timber buyers, and timber processors for efficient utilization of the resource for lumber, veneer, pulp, or other products.

This book was released on 2018-03-17 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lumber Recovery of Douglas-Fir From the Coast and Cascade Ranges of Oregon and Washington Volume recovery differed by log diameter, among mills, and by the units used to measure both logs and lumber, and may differ by whether the logs are measured as they come from the woods or after they have been bucked to mill lengths. Regres sion curves of recovery ratio, lumber recovery factor, or cubic recovery percent are plotted for both woods-length and mill-length logs. The cubic recovery percent for the combined mills reached about 76 percent of thalog volume for logs greater than 20 inches. Recovery ratio ranged from 225 to 130 percent across diameter.

Book excerpt: Excerpt from Lumber Recovery From Large, Highly Defective, Low Grade Coast Douglas-Fir General product recovery information is presented in table 1. There was no significant relationship between percent of lumber recovery (overrun) and diameter, but there was a significant relationship between percent of lumber recovery and percent Of estimated defect. Lumber recovery percent increased as defect percent increased, indicating that recovery percent was more closely related to estimated defect than to diameter.

Download or read book Veneer Yields by the New Timber Cruising Grades for Old Growth Coast Douglas Fir Classic Reprint written by Richard O. Woodfin Jr. and published by Forgotten Books. This book was released on 2018-03-22 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Veneer Yields by the New Timber Cruising Grades for Old-Growth Coast Douglas-Fir An adequate log or tree grading system for a given species is developed from analytical studies of timber characteristics and their relationship to-end product yields and values. The new log grading system for Douglas - fir, on which these recovery data are based, is that type of system. Recent publications (4, 6) give lumber and veneer yields based on the present Forest Service sawmill log-peeler log grading criteria for Douglas - fir. The study trees were selected to be representative in size and quality of west - side commercial Douglas-fir timber. Logs from these trees were not intended to be representative of the typical log mix at a mill. Logs were bucked, sawn, and peeled according to normal practice at each study mill. Public agency check scalers or scaling supervisors scaled all study logs according to uniform Bureau rules._1/ These rules are described as Forest Service instructions for west - side log scaling and grading. The lumber was graded by, or under the direct supervision of, a quality supervisor of the Western Wood Products Association, West Coast Lumber Inspection Bureau, or the Pacific Lumber Inspection Bureau. All veneer was graded by, or under the supervision of, the American Plywood Association or the Timber Engineering Company quality supervisors.

Book excerpt: Excerpt from Lumber Manufacture in the Douglas Fir Region The low, intermediate, and high figure Of costs of operation, repairs, and supplies are meant to cover not the range for mills of any specific size but the general range for all classes, regardless Of size or type. SO far as pos sible, the effect of size or type of Operation has been mentioned with other factors bearing on such costs, but sufficient data was not available to bring out in each case the exact effect Of size of Operation on the particular cost item. The machinery and equipment prices are those in effect in 1916. The costs per thousand feet are in terms of the volume of finished product and not log scale or other temporary volumes. The drawings of machines and equipment are entirely for illustrative pur poses and must not be considered in any sense as an endorsement of the style or types shown.

Volume recovery varied by scaling diameter but not by log grade. Value recovery and percent vol ume by lumber grade did vary by log grade and diameter, but no difference was found between the grade 1 and the grade 2 logs.

This book was released on 2017-11-19 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Lumber Cut of the United States in 1905 The total out of yellow pine was probably little, if any, greater in 1905 than in 1904. The cut of White pine was certainly no greater. The cut of Douglas fir increased remarkably, because the capacity of old mills Was increased and many new ones were added. The cut. Of fir in 1904 was also below normal, owing to unfavorable market conditions. There was probably a Small decrease in hemlock. There was probably a Slight decrease in the cut of Spruce. The Census Shows a decrease of 34 per cent in oak from 1899 to 1904, and this decrease is undoubtedly continuing. There was also some decrease in poplar, a continuation of the decrease of 18 per cent Shown in the Census returns between 1899 and 1904. There Was evidently an increase in cypress, maple, and the miscellaneous group, including a. Large number of species of. Minor importance, many of which are being Substituted for those which are obtained With. Increasing, difficulty. Table 2 gives the kind and quantity of lumber cut by the establishments from which the Forest Service received -reports. Yellow pine is far in the lead, with 8 feet, or 28. 8 __per. Cent of the total cut; and this lead would have been increased to at least 34 per cent if full. Reports had been secured. White pine fol lows, With feet, or 16 per cent, next Douglas fir with 47 9 000 feet, or 14. 2 per cent; then hemlock, with 2 804 083 00 0. Feet, or 9. 3 per cent. The relative.
