				break down slabs, cants, or flitches into lumber.
Running line
. Any moving rope as distinguished
				from a stationary rope such as a guyline.
Safety factor

				wooden beams and other mechanical members; ratio of breaking load to safe
				load.
Saw guide
. A device for steadying a circular or
				bandsaw.
Setwork
. A mechanism on a sawmill carriage which
				enables an operator to move the log into position for another cut.
Sorting gaps
