Ahhh… The IGO-W. Simple. Effective. What more can you ask for?
I am a big fan of both the IGO-L and the IGO-W. I haven’t used my W in a while so I decided to pull it out and whip up this illustrated guide to coiling it quick and perfect.
For drippers of this style, I have really become a big fan of using the Dragon Coil method.
The idea of a dragon coil is to tightly wrap your wick around the coil, while leaving both ends of the coil completely open for air to flow through. In theory this should produce a lot more vapor, and in practice, it certainly has for me.
They are super easy to do on drippers, and only take a minute or two to set up. For this you will need some Kanathal – I use 28ga, a 1/16 drill bit and some cotton.
PLEASE NOTE – Rebuilding any atomizer can potentially be very dangerous. Please do not attempt to build crazy sub ohm coils unless you know what you are doing.
Step 1 – Wrap the Coil
Clip off a nice chunk of Kanthal – I use 28 ga, but you can really use any kind. The size you use will affect the ohms, so you will need to use more or less wraps depending on the gauge you have selected. Take your 1/16 drill bit and tightly wrap a coil around it. There shouldn’t be any gaps between the coils – rather they should all be touching uniformly.
Once you have wrapped the coil around the bit, keep the bit inside the coil, and attach it to the posts on the IGO-W. When you are done you should have something that looks very similar to this:
Make sure you check your ohms at this point. I personally don’t usually go anything below 0.7 ohms. This particular coil for me came out to 7 wraps at about 0.9 ohm.
Once you have confirmed that your coil is the correct ohm that you want it to be, clip off the excess around the post.
Once you have a coil that looks like the above, or hopefully better, you are ready to wrap it.
Step 2 Wrapping the Coil
I take a fairly small piece of cotton ball and roll it so that it is about as wide as the coil. It should look like the picture below:
Once you have rolled the cotton, you need to thread it around the coil. Make sure you keep the drill bit through the coil for this step, as it will greatly help you make sure the airhole is not obstructed by cotton wick. I usually go in from underneath, and pull one side through and up. You should end up with both ends of the cotton meeting above the coil. See the picture below:
Now take both ends of the wick and twist them together like you would a twist tie. Make sure to twist them very tightly and all the way down so that it is tight against the coil. The cotton should be fully and tightly wrapped around the outside of the coil at this point.
Once you have done this, tuck the remaining wick under the coil. It should look something like this:
You shouldn’t have any coil showing, all you should be able to see is a clear hole going straight through the coil.
Once you’ve done that, you are ready to go.
At this point, before I put the top cap back on, I like to make sure I get the wick completely saturated with juice. This way, you can make sure there are no spots where you could potentially dry burn, and you can also double check that no outside areas on the coil are exposed. Once your coil is soaked, you should also be able to move it around and position it easier.
I also like to give it a test fire before putting the top cap back on. Here’ s a quick vid of my dragon coil just after wrapping and soaking the wick:
Pretty sick vapor for a quick coil and wick job, eh?
If you did it right, you should have vapor flowing out of both ends of the coil, just like in the video above.
Once you’ve got that all set, you can pop the top cap on and start vaping. Make sure that you align the airhole on the top cap with the coil to get maximum air on it.
NOTE – you can adjust the amount of cotton around the coil – particularly how much you have underneath. You should be able to fit quite a bit of cotton under the coil if you want to be able to hold more juice, however if you notice your coil spitting and gurgling, you probably have too much. For this particular tutorial I used about the minimum amount of cotton you would possibly want to use, so definitely feel free to experiment by adding more.
Also, regarding the coil diameter, I have done these with a much narrower diameter than 1/16th drill bit, so you can feel free to experiment with that as well. I like 1/16 for the IGO-W, because at about 7 wraps, it comes out at almost a perfect distance between the two coils.
Obviously, with the IGO-W, you could easily duplicate this on the other post for a dual coil setup, however you will need to make your coils with twice as many wraps, and you will probably want to widen the airhole. I think you will find that this single coil setup will kick a basic dual coil setup’s ass.
