Veneers from bagras (Eucalyptus deglupta Blume) were dried in a roller-conveyor type dryer. ontrolled variables were veneer thickness, drying temperature and drying time. Samples of veneer using three thicknesses: 1.07, 1.27 and 3.63 mm, were dried at temperatures of 82, 105, 138 and 166C using two drying times for each level of temperature. Internal air velocity was maintained at 365 meters per minute, with the air-venting stack kept closed during the tests. Green moisture content varied between 34% to 103%. There was a discrepancy between the target dry moisture content and observed dry moisture content. This was caused primarily by the initial moisture content of the veneer. The shrinkage values showed no significant pattern of variation for each thickness using different temperature
