Understanding the stability of Douglas fir timber

August 2007
New Zealand Tree Grower;Aug2007, Vol. 28 Issue 3, p3
The article focuses on a project created by the Douglas-fir Association in New Zealand to obtain depth understanding of the stability performance of Douglas fir and to develop tools to segregate logs before processing. In the first phase of the project, logs of both Douglas fir and radiata pine were sorted on acoustic velocities, using a simple sonic tool. It has now entered into the second phase for property measurements and timber sawing. For the project's final phase, mill studies will be conducted on the kiln drying of the Douglas fir and radiata pine timber.
