I've known Ed since about 1970. We started Bella in Denver together after working with Joe Leiper in Boulder. https://en.wikipedia.org/wiki/Morgul-Bismark Later we both worked at a frame building enterprise in Cambridge. I designed the jig that Ed used. It was built with the help of Dr. Frank Melsheimer of DFM Engineering (now in Longmont CO) (https://www.dfmengineering.com/). Frank also made a jig for himself from my plans and built some frames for Zeus USA, but that was just a hobby. Frank's main business is building telescopes, big ones. They start at 16" and go up to 50"+. While many American frame builders were silver soldering at the time, we decided that the Italians built the best frames in the world and they used brass, so that's what we used for the extra strength, except for the tips where we used Nickle Silver for it's hardness and filling quality (advice from to Joe Leiper). Early on we built with Super Vitus tube sets and Cinelli lugs and BBs. I wasn't interested in moving to Boston and went into IT in Denver.
