I was wondering if I am the only one here who has thought about doing this. I had at one point tried making a string, which turned out decently, but with some issues. We have rolls of ~.045" steel wire laying around in our barns, so I took a length of it and strung it up. I didn't clean it off, but it sounded ok in place of the G string. Only it snapped after hitting about D. So I decided to wrap one. Sat down, with a length of 22 guage bare copper wire, and started winding. Mind you, I don't have a machine, so it took about three hours, and I ran out of copper after 12" of core. I have this little harpish dulcimer thingie, so I strung it on there to test. Sounded nice and smooth, and would have been longer and more beautiful sounding if I had more copper. I hadn't taken my time, so the windings were unevenish, which I think is why this time it wouldn't hold its tuning. My question is, if I hadn't rushed, and wound the wire more evenly, would that have help the tuning stability? Also, we have this old wiring in our barn that we tore out of the house to replace, and there's plenty to make a full string, plus it's thin. I am unsure o what it is and whether it would work. It looks like aluminum, as it's grey (or is it gray? I can never figure ou the spelling on that one...) on the outside, but when sanded down it's kinda copper-colored. It's the stranded neutral wire around the two hot wires that led into the house. To give you an idea of what I'm after, I've wanted to do this after learning how piano strings are made, as I love the sound of the bass register, with those thick copper-wound strings.
