The Pattern Shop is equipped with benches, tools, and lathes for divisions of thirty students. The work here is designed to give a practical knowledge of the mechanical processes and the materials of construction by means of a graded series of exercises having in view the formation of habits of precision and the development of judgment essential to the engineer. The work in this department maintains a close relation with the courses in drawing and design.

The first half of the Freshman year is spent on Joinery, Wood Turning, and Foundry, Joinery gives the elementary use of ordinary bench tools. Wood Turning is carried through straight turning, face plate, and chuck work. Foundry work, which is designed to give the necessary preparation for pattern making, takes up green-sand moulding in two-part and three-part flasks, with solid or split patterns, green-sand and dry-sand cores; also core making, and casting in soft metals. The course in Pattern Making includes work on simple and split patterns, built-up work, and core boxes. Considerable time is spent in the study of special problems.
