Publication Series: Research Paper (RP)

Description: A total of 363 western hemlock (Tsuga heterophylla (Raf.) Sarg.) logs from Alaska were sawn to compare recovery at a stud mill and at a dimension mill. Recovery at both mills varied by log diameters and by log scaling system. Lumber grade recovery was primarily in Stud grade at the stud mill and in Standard and Construction grade at the dimension mill. Lumber volume recovery is based on long log Scribner scale and on cubic scale. Lumber recovery was 2.23 times the Scribner volume at the stud mill and 2.05 times the Scribner volume at the dimension mill. The lumber recovery factor was 9.0 at the stud mill and 7.5 at the dimension mill.

Keywords: Lumber yield, lumber recovery, lumber volume, log scaling, western hem-lock, Tsuga heterophylla, pulpwood logs, dimension lumber, Alaska
