Don Isaac received his BSME from Northeastern University in Boston, MA (1970). He began work as a design engineer for Square D at the Motor Control Division in Milwaukee and later at the Circuit Breaker Division in Cedar Rapids. Moving around the Midwest, he also worked in the welding machinery, nuclear plant service, and machine tool industries. In 1979 he moved to California, where he worked for Lockheed Missiles and Space. There, he was involved in projects ranging from large vacuum systems design/testing to radiation spectrometers and cryogenic systems for space flight.
In 1995 he left Lockheed to develop Stirling engines at Tamin Enterprises. Tamin Enterprises was founded in 1983 as a partime activity developing counted cross stitch designs and kits. Tamin's activities have evolved into a full time business with activities including machine/tool design, Stirling engine design, and metal sculpture production.
This engine ran for the first time on 31 MAY 94 and was demonstrated during the informal Stirling session at the 1994 IECEC conference at Monterey California. The engine was hard starting then because of leaks in the displacer which was not completly welded closed. Seal welding all around both ends eliminated the dead volume and resulted in increased compression (a very snappy engine) and easy starting. Once the heater head is heated to operating temperature, the engine will start by slowly rotating the flywheel past piston top dead center. The engine will snap past top dead center and continue to run.
