I've taken up metal sculpture over the last 10 years and since retiring from being a city administrator Aug 2016 have been able to devote more time to the passion. I find I am interested in larger items and even some kinetic elements (nothing large there yet.) So I have relearned some geometry, learner about the physics and chemistry of welding and reading "Structures in Sculpture" now. I want to explore some HSS issues for a piece I'm working on and am happy to find this community.
