I focus on devising novel mechanical (no solder, no glue) construction methods that combine fundamentally-different industrial materials, plus some traditional jewelry components, to create earrings (primarily) and bracelets and necklaces. I base my jewelry techniques on information-related skills I learned in my engineering studies (I have a doctorate degree) and in my engineering career (30 years, now retired). Many of my engineering activities (and my two patents) were related to mechanical systems. Industrial components I use include rubber shapes (rings and cords), electrical signal connectors, heat sinks (spoked-ring radiators for cooling electronics), gears, bearings, and brilliantly-colored laser filters. My home is an artist live/work condo in a recently-converted textile mill (www.123sawtooth.com).; www.industrialjewelry.com
