It was probably about 30 gauge (guessing here), and I would tape the wire to the side of a trashbag or newspaper waterproofing bag (yes, you sense a bygone paperboy here). I would fill the bags with .5 Acetylene and .5 Oxygen, and then hook the thin wire up to the 12 volt car battery, and it would glow read, melt a hole in the bag, and ignite the mixture. I stopped doing this trick when One day I had oil on my hands and the Oxygen spotaneously ignited the bomb in my hand. (No permanent damage!). At any rate, try the thin wire. Another thought is the fuses that Estes model rockets use. They should light on up just fine! I do not know how you can contact them, but their factory is (was when I lived there anyway) located in Penrose Colorado. Good luck!
