Before I attempted to rebuild a coil.. I wanted to see one and try installing it myself. I ordered
premade coils (with wicks) at avidvapor for $1 each and was able to practice installing it before I decided to order wick and wire. The only thing about the premade wicks is the coils are extremely small.. no way I could wrap something that small and close.. my coils are bigger and I guess that's why my resistance is so low. I have a multimeter but it's not wanting to work right now for some reason but I can check my resistance on my provari. Be careful recoiling.. if you get a short (which will happen sooner rather than later) you will need a device that won't be harmed.
I am now happily recoiling/rewicking my heads with cotton and it's working pretty good

All my coils meter around 1.7-1.8 ohms, so I start them out at super low voltage.. 3.3v and slowly work my way up. Cotton wicks burn easily if the voltage is too high and they're not wet enough. It's taken my quite a bit of trial and error as far as rebuilding and lowering my voltage but it's been fun
and yep.. I watched
pbusardo and
Rockin Robbie and just did what they did. There is a lot of discussion on "hot legs" since the vivi nova doesn't use non-resistance wire for the legs. I haven't had an issue with that, just the cotton wick burning because the voltage too high. But many are doubling and twisting the legs to reduce the resistance. I just built a coil and I used a cotton ball for the wick and I doubled the legs. I haven't tested it out yet because I only have two vn tanks and as of right now both of them are vaping way too good to mess with LOL.
