I have worked with Ray since the mid-80's, during his employment with a local sheet metal/machine shop. He has helped me hone in on necessary dimensions on dozens of machine shop parts that his company has made for me. The most recent job he did for me was a sheet metal job which required tight tolerances for an aircraft battery cover. It fit perfectly into place. He has an eye for details and can speak to you in a language you can understand to solve complex engineering issues.
