I was refering to the traditional method. I would use the paperclip as a guidance for that method, a lot of people on the german forums do it that way. However I found that I can do it without guidance, so no need for it hereJust to make sure I understand y'all correctly. You are all not talking about a micro coil, which always requires a mandrel (be it a tooth pick, paperclip, drill bit, etc) and the wraps to be touching? You are referring to a coil where the wraps are not touching and where, traditionally, one would wrap directly onto the wicking material?
