I just got my first rebuildable about a week ago, A Kayfun 3.1 clone. Before experimenting with this my main tank was a nautilus with 1.8 ohm coils which really throws out mad vapor. I have built 3 coils the first read 2.2 ohms on my mvp 2.0 ( that's all I have to check them). which was vey well on vapor production but was pretty hot even on low voltage/wattage setting. my second and third have been 1.2s even though I twisted the third less times around the small screwdriver I have been using. the 1.2s are ok on vapor but not as good as the 1.8s have been. How do I go about getting 1.8 ohms or close to it? would increasing the diameter of the coil change anything such as wrapping it around something bigger?
