Interesting read that leads me to a question from James' comment about wire size and power. How would one determine that there wire is undersized for the set power? I have 26, 28 and 30 gauge. Outside of there own native resistance, should I expect any different behavior from each wire? And a comment. We take a device designed to measure temperature through resistance changes in a single wire with known, reliable coefficients and decide to use complex builds of home wrapped wire in single, dual, quad, etc. coils whose coefficient can only be measured in theory for a perfectly built wire, and you aren't making those. There have to be imperfections in the build, there always are and when you take that straight clapton wire and shape it into a coil, you are introducing new imperfections. And you are not considering the heat sinking that has to occur with the different wires/resistances. No matter what curve you use, it would be blind luck that you will get one that matches your custom wire. Not to mention the changes it goes thru during use and over time. A Temp Lock cannot be done if your temp cannot be determined. Stick with what is known and you will be fine, for the most part. Experiment at your own risk, but it will be no one's fault but your own if that does not work well
