It generally consists of base, knee, taper set, and mechanism. Head rig . A combination of head saw and log carriage used for the initial breakdown of logs into timbers, cants, and boards. Hog . A machine for cutting or grinding slabs and other coarse residue from the mill. Husk . A head saw framework on a circular mill. Industrial truck . A mobile, power-driven vehicle used to carry, push or pull material. It is designed for "in-plant" or "on-site" use rather than highway use. Kiln tender . The operator of a kiln. Lift truck .

Running line . Any moving rope as distinguished from a stationary rope such as a guyline. Safety factor . A calculated reduction factor which may be applied to laboratory test values to obtain safe working stresses for 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 . The areas on a log pond enclosed by boom sticks into which logs are sorted. Spreader wheel . A metal wheel that separates the board from the log in back of circular saws to prevent binding.
