Book Description
Results are reported for changes in grade and volume during kiln drying of Shop and Better grades of old-growth, coast range Douglas-fir lumber. Findings indicate that considerably more degrade occurs in the higher lumber grades than in the low. Wide thick lumber degraded more during drying than did narrow thin lumber. Log size and grade do not directly affect the amount of degrade, but may indirectly affect it through the grade and size of lumber produced.
