Abstract: A tandem sawmill assembly is disclosed having two linearly spaced sawing stations. A conveyor system moves the log through the first sawing station and up an inclined ramp for rotating the log ninety degrees prior to moving the log through the second sawing station. An overhead roller engages the re-oriented log and advances it to a centering platform where centering arms engage the log to orient the log axially with respect to the second sawing station. The conveyor then moves the aligned log through the second sawing station while a second overhead roller applies presssure to the upper surface of the log.
