The processed logs from site G had the largest proportion of green veneer recovered (68%) while site E had the lowest recovery with a little over 56 percent of the logs converted into green veneer. The proportion of the unpeeled core section, however, was greatest in site E with almost 14 percent while site G had less than 7 percent.
Douglas Fir Wood Veneer has a light reddish brown tone and has a high contrast between the earlywood and latewood. Generally found in quarter cut, more veneer and plywood are made from this species than any other. Douglas Fir is primarily found in the United States and Canada. It can also be found in the United Kingdom, New Zealand and Australia. Pseudotsuga menziesii is an evergreen conifer species in the pine family, is native to western North America and is known as Douglas fir, Douglas-fir, Oregon pine, and Columbian pine. Despite its common name, it is not a true fir (i.e. it is not a member of the genus Abies).There are three varieties: coast Douglas-fir (P. menziesii var. menziesii), Rocky Family: Pinaceae.

Excerpt from Douglas-Fir Cull Logs and Cull Peeler Blocks: Lumber and Veneer Recovery Veneer recovery is the square-foot volume. Purpose of these studies was to determine volume recovery, by grade of veneer, from the four principal grades of Douglas-fir logs processed at ply- wood plants.
In addition, supplementary veneer-recovery data were obtained from several studies similarly conducted by an independent consult- ing firm.

Excerpt from Veneer Recovery From Second-Growth Douglas-Fir Veneer trees were first marked so the cutter would know which trees to cut into peeler lengths.
All the areas were cut in April of At the time of cutting, the log ends were tagged with the tree number, woods-length log number, and veneer block position within the log.
All logs were. INTRODUC Duringthe Pacific Northwest Forest and Range Experi- ment Station made a series of six veneer-recovery studiesL1 in the Douglas-fir region of Oregon and Washington. The net volume of logs involved totaled approximately M board-feet.
Veneer logs were peeled into nominal 1/8-inch full sheets, half sheets, and random width veneer. The proportion of log volume recovered as rough green lumber differed with log diameter and log taper.
Lumber recovery increased with log diameter and decreased as taper increased: log diameter had the most by: We peel Douglas Fir and Western Larch logs from 6” to 31” in diameter Acceptable log lengths are 17’6”, 27’, 35’, and occasionally 43’6” Logs are cut into ” blocks, and the blocks are “cooked” at degrees in 8 vats for approximately 12 hours.

Problems Associated with Veneer Peeling Historically, the major problems which cause reduction in veneer yield have been spin-out, large core size, and unpeelable logs.
Spin-out This occurs when the torque required to peel a log exceeds the amount which can be transmitted by the.

The major advantage of heating was increased recovery of A-grade veneer because of reduced splitting. Preheating increased value about three times more for the low quality Special Mill Logs than for the high-grade Number 2 Peelers.
Subsequently, Corder and Atherton () evaluated the quality of veneer recovered from Number 2 Douglas-fir Sawmill Logs.
