Splitter profiler

A method of converting an existing profiler module to a splitter profiler module, wherein the existing profiler module includes a frame, an arbor rotatably mounted to the frame, and means for mounting one or more profiler heads to the arbor, the method comprising:

• movably coupling a first saw arm assembly to the arbor such that the first saw arm assembly is movable in opposite directions along a path of motion that is generally parallel to the arbor, wherein the first saw arm assembly is configured to retain a circular saw blade and to transmit rotation of the arbor to the circular saw blade;
• and
• operatively coupling a first actuator to the frame and the first saw arm assembly, wherein the first actuator is selectively operable to move the first saw arm assembly along the path of motion.

A non-transitory computer-readable medium comprising instructions that are operable, upon execution by a computer processor, to cause the computer processor to

• determine, based on a cut solution for a workpiece, that the cut solution defines coplanar sideboards to be cut from a side of the workpiece,
• based on the determination, identify a corresponding splitting position for a circular saw mounted to an arbor and axially movable along the arbor, and
• send the splitting position to a positioner operatively coupled to the circular saw and operable to reposition the circular saw to the splitting position.

A method of obtaining coplanar sideboards from a primary workpiece, such as a log or a cant, the method including:

• using a first profiling head and a second profiling head to form respective outer longitudinal edges of two of the sideboards along a first side of the primary workpiece, wherein the first and second profiling heads are mounted along an arbor;
• and
• using at least one circular saw mounted along said arbor to form an inner longitudinal edge of at least one of the sideboards, such that the inner longitudinal edge is formed at substantially the same time as the outer longitudinal edges.
