THIS THING TAKES NAMES! Seriously it's not a novelty coil, it's been charged with statutory vape.


Hey all, I tried the "Inception coil" a while back expecting an interesting vape, was a little disappointed that it wasn't at all, just another "novelty coil". So I had the idea to try and make the "outer coil-inner coil" system work.


There were three things wrong with the "Inception Coil" in my experience:
1. It didn't produce alot of vapor, and took way too long to heat up.
2. It didn't heat up *evenly*.
3. It wasn't worth the hard effort of building, wicking, and the ohms were a little high (for my tastes) due to the one long piece of kanthal design.


So I decided to try and fix all these problems, while keeping the same "coil inside another" idea, because I thought this was the coolest idea, basically squeezing vapor between two hot coils. I came up with a kind of "best of both worlds coil", where I would take my favorite vapor producing coil the super-nano, and surround it with my favorite flavor coil; a 5/64th's" macro-coil that's slightly gapped between the wraps. I used 24ga wire, to keep the ohms low, also to make them two separate coils, and twist the connection legs together to make it a paralell build.


So I was hoping that this would keep the ohm's low, produce vapor fast, while still making great flavor. And it couldn't have been more on the money! It's just like vaping these two coils if I had them separate in dual coil mode, but even better! Better because it heats up in an instant, and has flavor that super-nano's just can't come close to making, the vapor is incredibly dense, and it uses juice really efficiently too. When I check it visually when I sense it getting dry, it's usually used up all the juice available, the best part is though: it produces gobs of vapor, while not being sensitive to dry hits. I don't know if it's because of the sandwiching, or two coils pulling juice at the same time, but it's a bullet-proof setup! Easily one of the best single coils I've ever tried (I haven't tried too many other than the standard nano, micro, macro etc., and not as of lately so take that with a grain of salt. ;) ), and it performs comparably to any dual coil as well.


If anybody wants to know, I basically just: Wrapped a super-nano (24ga), a macro 5/64th's on a similar size screw (24ga as well), equalized the ohm's so both coils were the same ohm'age, bent the legs on the super-nano to fit the coil inside the other, adjusted the coils to line up perfect and held the inner coil steady with wedged cotton while I twisted the coil legs together. Adjusted the coils to glow proper, wicked 3 cotton strands between the Inner coil & Outer coil (sandwiched), and tucked some light cotton under the beauty. It came out to 0.3ohms, and vaped like a beast, a flavorful beast; so much so that I had to stop using a sweet juice because it was too rich.


Here's some pics I took during the build:

<---Pic really doesn't do it justice, it blasts vapor in 3 directions, from both sides of the super-nano openings, and from


the front, out of the spaced 5/64th's" coil face.


When I first vaped it I thought it was going to be like any other "silly" novelty coil, and not really work well. But I couldn't have been more wrong, it's a darn excellent vape! It's not as hard as you may think to build either, certainly more easy than the "Inception coil", but 5x more worth it for sure. I'll definitely be building this in the future again, possibly TWO of these bad boys, I know that would kick some major rear end.


Hope someone enjoyed this, and if you like "single" coils, definitely give this bad boy a shot! Vape onward y'all. :vapor:


(I took a quick video of this coil performing too if anyone wants to see, I'm just having some technical issue's trying to convert it!)

HOLY FLUFFING CRAP!
this thing is crazy! And wasn't as hard as I thought it would be, I figured matching ohms would be hard but with the help of vapors toolbox and my millimeter it was easy peasy hardest part was wicking and crap it wasn't that hard.
Major VAPOR great flavor, a little warm for me fully charged.
Came out to .25
24g-Id .8mm, 24g-Id 3mm

I was thinking the same thing. Glad to hear it worked out good.

Following along, got the coil built. Used 24g A1 Kanthal, outer coil, 3mm, 7 wraps.
Inner coil, 1.4mm, 12 wraps.
.5 ohm total.

How do you get the wick in there?

Edit: Nevermind, I bent a spare piece of Kanthal in half and used that as a needle to thread the cotton through.

I think I messed it up, it's not really "chucking the vapor" but the flavor is great.

Oh it's not hard at all, since the inner coil is half the size of the outer coil (IC: about 1/32", a 24ga super-nano. OC: slightly larger than 1/16th"), all you have to do is make sure the inner coil has about double the wraps of the outer, and it turned out perfect. This is sort of one of those novelty coils, that happened to work out great, but I haven't built it since then to actually vape, I did dual coil this and it kicked me in the teeth flavor wise.

If you want to know exactly how to make it, wrap 24ga 8 times on itself for the inner super-nano coil. I used a micro-screwdriver for the outer coil at slightly larger than 1/16th", and wrapped it 5 times (not 4 because I wanted to space them for vapor release, thus would mess up the ohm balance, that extra wrap evens it out.). Bend the inner's legs so it can slide in the larger coil, wedge some cotton between them so the inner coil stays aligned, and twist the legs together for an even connection. Piece of cake! I wouldn't build it again because it's not really worth the extra effort, but if you know what your doing it's a pretty fun build!
