Development of a sandcasting process for an Atlantic Marine Engine

Abstract

The Atlantic Marine Engine, designed and manufactured by Lunenburg Foundry of Lunenburg, Nova Scotia, is a historically significant gasoline marine engine from the beginning of the 20th century. The Atlantic and other similar engines transformed the American and Canadian fishing industries with their power and reliability. A project to recreate a historic J model, single cylinder, two-cycle "make and break" engine is ongoing at MIT's Pappalardo Laboratory by a number of students. This thesis will focus on making progress towards a completed engine with the design and fabrication of the engine base. The fabrication will continue to use a traditional sandcasting process, but will explore the viability of using computer-aided design and manufacturing (CAD/CAM) processes to make high quality patterns out of high-density polyurethane foam.
