Otto Clausing also had a small workshop in the "garage" behind his house which he used to manufacture a small twin-wheel grinder that had first gone into production in 1938. Otto's had moved to Willard Street in 1943, and shortly after had set up machine tools in the building behind the house. Ralph Williams came from the main factory to be the foreman. I worked there during the summers of 1945 and 1946 with both Bonnie and Dale - who were older, and much more productive than I was ...
Otto continued this business with the grinders being sold through the Clausing Manufacturing Company, and I believe that this arrangement continued under Atlas. In the Fall of 1952 Keith Nelson transferred from Atlas-Clausing to work for Otto.
