Good Day Everyone. I am a retired oil&gas executive who has had the opportunity during my career to cultivate numerous hobbies such as a piper in a band, stringed instrument making, furniture making, wildfowl carving, stained glass, various sports and martial arts, and silversmithing. I've been working in the silver field for about 1 year now, and found your site about 3 months ago. I'm really impressed, and humbled by the expertise on this group. I only hope that, over time, I can contribute something that will help others. You've already helped me in some projects a great deal.
