Somewhere else on the forum today, I noted I had found a Variac in a bin. In the same bin, I found 6 old reels of fine-gauge (various different gauges) copper wire, which, rather to my surprise, turns out to be un-enamelled. So my question is - what do you think it was for? I should have included something for scale - the bobbin is about 4" dia and the same high. There's quite a lot of wire!
My current long-wire is enamelled, so I guess I can reclaim that for another purpose and put some of this lot up. That will leave me with 5 63/64 reels to go. Perhaps I can wind it between two pegs along the side ginnel, and when I have walked up and down a hundred times, put one end in a slow drill chuck and make some monster un-insulated jump leads
ETA - or monster un-insulated speaker cables. Wa-hey, I'm sure it's oxygen-free long-grain whatever, and it's definitely 'retro'
