My main duties were reverse (back) engineering but I was exposed to all facets of the company operations including purchasing and general manager. I'm a gear specialist. I had a custom machine and gear shop for almost 15 years where I could develop prototypes and custom machine parts away from sight. I wrote custom software to construct accurate involute tooth profiles on modified base circles in DXF & DWG formats. I retired and provide back engineering, new design, drafting and engineering for several companies in the Great Lakes region of the USA and now around the globe. I'm also an artist/Illustrator, working in all mediums and specializing in chalk,oils and pencil portraits
