like the thread i got 28/29g kathel and wrap about 6 wraps on my blue kayfun screwdriver it gives me around 1.1ohm how many wraps do i need for a sub ohm?
If you are going to dual coil put another wrap on so its 1.2 then make another the same put them on you atty together on this will give you 0.6. 1.2 Divided by 2.
Or if you are going to have a single coil then half the wraps to 3 this will give you 0.55.
I would get some thicker Kenthal 0.32 then you can make more wraps for less resistance.
Also make sure batteries are up to it so you dont blow yourself up ..... is your mod up to the challenge ?
I use 30G kanthal and 14 turns around an 18G syringe needle, along with the method of threading the cotton through, gives a pretty nice vape. I found it comes out at roughly 1 ohm.
