This is a brief tutorial on how to rebuild a Kanger Dual Coil into a single microcoil.
I have had great success rebuilding this way and I urge anyone reading this to seek out more tutorials, take bits and pieces from each and do what feels right to you. That is how I arrived at this method.
The Pros: Vapor amount is about the same as a stock coil but the flavor is easily twice as good, coil lasts longer, customizable and personally after rebuilding this way for 3 months I have yet to get a flood, leak, gurgle or dry hit.
The Cons: Wicking the coil with cotton prior to installing prevents dry firing (I've never had any issues though).
Warning: Rebuilding Kanger coils is relatively easy but you must test for shorts and check the resistance prior to installing in a clearomizer. Always ensure the coil gives a good resistance reading and you are vaping at appropriate Ohms for the battery.
And away we go...
These are the tools I use to rebuild...
Stanley Micro Screwdrivers from Wal-mart
Multi-meter from Home Depot
Bernzomatic Micro Torch from Home Depot
30 Gauge Kanthal (What I prefer to use)
Sterile Cotton Ball
A stock Kanger dual coil looks like this when broken down...
Left to right: Pin, Grommet, Head (or base), Stock Silica Coils, Chimney
I have found that a 2 mm microcoil holds enough cotton to fill the large gaps in a Dual Kanger head. 2 mm is about a 5/64 drill bit.
I start by using "Vaper's Toolbox" Android app (free on Google Play) to determine how many wraps I am going to need to get the Ohms I want. (I like 1.5 to 1.7 ohms = 6 wraps)
I make a 6 wrap microcoil...
Gently compress the coil with steel tweezers and torch until the coil glows orange for a few seconds...
I do this to burn off any residue and to tighten up the coil. You can use a regular lighter, candle, gas stove, etc... but a microtorch works best ($15 at Home Depot)
Pinch off some cotton, roll a tight wick between your fingers and thread the coil...
The cotton should fill the inside of the coil without being tight. If the cotton fills the coil but can be pulled back and forth with little resistance then it's good.
