@cypnk ... I've done "soldering" only when doing stained glass art when I was in high school. I'm not sure what is involved in actually winding these coils correctly in order to get the right effect. Theres lots of knowledge like that I would need to experiment with. Of course I would love learning it. I am trying to find a way to have a lot more free time and have a workshop area for such things. As far as a home workshop I've only gone as far as almost completing putting together an engraver..
