This shop is a woodworking shop devoted to the making of wood patterns for the foundry. These patterns are used as models for shaping moulds of articles to be cast from molten metals.

A pattern maker must be an expert woodworker, and must be skilled in reading correctly the most intricate mechanical drawings. He must also be versed in the methods used by the foundryman in making moulds, to know how to make patterns in forms best suited to foundry requirements yet not unnecessarily costly.

Cabinet making and joiner work may be done by pattern makers with pattern-shop equipment, but in large ship and machine-building establishments, the pattern shop and joiner shop are usually separate.
