As promised, reposting this from the last long thread ...
So, rebuilding a GS-H2 coil head (this method is the same for evods, protank heads and probably a few more):
You will need -
- a steady hand and fairly good close-up eyesight
- something to read ohms. If you have a vamo or an mvp you already have this. If not, these work well. You can use an ordinary multimeter but you need an extremely steady hand to get a stable reading.
- a pair of nail clippers, wire cutters or even sharp scissors for cutting the wick and wire
- needle nosed pliers, fine tweezers or just a good strong thumb nail are useful at various stages of the process.
The method I use is similar to except I push the pin carefully through the centre of the wick before coiling. I also don't bother with dry burning and soaking the new coil. Instead I run a lighter along the wire until it glows red before coiling. This also makes the wire a bit less springy and easier to work with.
Using 3mm wick and 0.2mm kanthal, I get 1.8 ohms from 4 wraps and 2.2 ohms from 5 wraps.
It's a good idea to watch a few different videos (search on youtube for evod rebuild) as everybody has a slightly different way of doing things. This way you will get an idea of what the essential parts of the process are and what is just personal variations. Over time you will develop a method that works for you.
Expect your first attempt to take about an hour and to involve much swearing 
It gets easier very quickly as you learn the knack. I can do one in under 5 minutes now.
Good luck!
