1. Make one flat trim cut as deep as possible.
2. Make a second trim cut at approximately a 30° angle to the first cut.
3. Make a third cut at a 30° angle to the second cut.
4. Cut a board off the flat from the second cut.
5. Alternate cutting surfaces until the log is small enough to be cut straight through.
The resulting boards will have to be trimmed to obtain square edges. The board thickness will be limited until the log is trimmed to at least the rated maximum capacity.
