In many cases hand-shaping is indispensable, such as sudden breakage, operations abroad, and on board ship; also for constructors having a limited number of machines. Turning and screw-cutting occupy the last chapter. In this, the operations for lining, centering, turning, and screw-forming are detailed and their principles elucidated.

The Mechanician is the result of the author's experience in engine making during twenty years; and he has concluded that however retentive the memory of a machinist might be, it would be convenient for him to have a book of primary principles and processes to which he could refer with confidence.
