  1. Continued from Part 1 (http://www.e-cigarette-forum.com/forum/blogs/btsmokincat/6205-aerotank-pt3-rebuild-dual-single-part-1.html)...

    Feed the leads into the head and pinch the cotton against the sides of the head to hold the coil in optimal position...

    Gently fold over one of the wire leads and pinch against the side with the cotton. Feed the other lead through the rubber grommet and squeeze, pinch, curse and push the grommet into the head. One wire lead should be between the grommet and the head and the other lead through the center of the grommet...

    Gently fold over the other wire on the opposite side and insert the pin. Clip the loose wires with a nail clipper as close to the grommet as possible (any wire that is sticking out could cause a short). Use a small screwdriver to adjust the coil if it is not perfectly centered.

    Trim the cotton so it sticks a few mm out each side and fluff with something small (I use my smallest micro screwdriver)

    Fluffing fills the openings with happy little cotton clouds.

    Press the chimney back on and one last thing to do

    Check your resistance (Ohms) to ensure you got what you were aiming for and to ensure there are no shorts ( wire broken or touching the inside of head or chimney). If it reads good on a Multi-meter, Mod or Ohm Meter (pictured) you are good to go!

    Just what I was aiming for!

    Vape on and enjoy.

    Please comment any suggestions, tips or tricks for others looking to rebuild these Kanger Dual Coils!
  2. 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
    Ohm Meter
    Nail Clippers
    Steel Tweezers
    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.
