. Veneer recovery of red and white fir-- California. Veneers and veneering; Lumber Mensuration; Abies concolor; Abies magnifica. Each tree was examined before it was felled, and surface characteristics for the first 32 feet were diagramed (1, 3). The felled trees were bucked into logs of multiple 8-foot block lengths. Small unpeelable logs from the upper part of the tree and segments less than 8 feet long were not considered study- material and were not processed. Maximum bucked length was 34 feet. Log Diagraming, Scaling, and Grading Before the bucked logs were skidded, visible log surface characteristics were diagramed, tree and log diameters and lengths were recorded, and logs were tagged for identification. Logs delivered to the mill were decked and kept under water spray until removed for debarking and bucking into blocks the day before they were peeled. These blocks were scaled (6) and retagged for identification. Individual blocks and short logs (composite of two blocks) were graded by applying the Forest Service grades for white fir to the log surface diagrams (7). Peeling, Drying, and Grading According to mill practice, all study blocks were steamed for approximately 18 hours at 180° F. The 977 blocks in the study ranged from 7 to 48 inches in small-end diameter. Block lengths and diameters were measured before they were peeled. 2.
