I'll just give you a quick run-down, those threads are a pain to wade through.
1: boiled and dried cotton or bamboo yarn
2: you'll probably need thicker gauge wire because you want a much fatter coil, try building one 2,5mm in diameter with 28 gauge
(a bigger coil means it needs a less resistive wire to cover a suitable microcoil area)
3: you'd want your build around 2 ohms for regulated devices, for mechs I wouldn't recommend sub-ohm builds in the kayfun
wicking tips for cotton or bamboo:
1: get it through and trim it right to the bottom of the chamber where the juice will flow in (just make sure it's not short and float above it)
2: screw on the cylinder part of the chamber
3: gently tuck the material down to reach the bottom
4: move tuck the wick to the sides, clearing away the juice channels, it makes 2 V-shapes and your build will roughly look like this (>[ß]<)
(5: Don't forget to prime with juice!)
I found the V-shape to be great for wicking. Your build doesn't always taste right straight away just give it an hour or so. Quenching my coil and plenty of test-firing before use seems to help for me.
Quenching is where you heat it up to glow without wicks in it, and then run some cold water over.
