Months ago, I saw a video on YouTube with a small coil which resembled a barrel. I was unable to find the video, recently, so I spent time during the last 7 days trying to make one via safe experimentation. The first one I made worked fine until the 36 gauge Nichrome 80 melted off from too much priming. I think it is best to use this coil with 29.5 watts. Some photos of it are below.
The photo above shows the coil before I threw it out. Though it worked fine before I ruined it, it did not perform as well as I thought a variation would. The photo below is of the coil before it was ‘over-melted.’
The coil above was one of my first attempts with a barrel coil. It was installed in a Taurus RDA and wound with 26 gauge Kanthal and ‘barreled’ with 36 gauge Nichrome 80. Its resistance was ‘about’ 1 ohm.
For most of my coil builds, I use an iPV4s regulated mod. I have tried out plenty of devices and like it the most, so far. I thought it only fitting to include a picture. The iPV4s takes two 18650 IMR batteries and shows ohms readings. I like it because I can use it to build coils for mechanical mods and other devices. Though it can go up to 120 watts, I do not ever use it over 60 watts. For ‘advanced’ coils I will use it at 60 watts, depending on the coil. I usually use it at either 40 or 47 watts with a dual 24 gauge Nichrome 80, 8-wrap dual coil build.
Let us continue with the barrel coil. I was hell-bent on building a good one after burning out the first small one I wound up. I built two more of them. The first of the two is in the two photos below. The RDA in the photos is the Shark RDA. The coil was wound with 24 gauge Kanthal and 30 gauge Nichrome 80. Its ohms reading was 0.71 ohms. Did it vape? Sure. Is there a good way to wick one of these? Probably. I tried it a few ways and left it alone. Largely because I still thought there would be a better way to wind one of these up. Why? Because of the way it heated up. The idea is for the wrap on the outside of the coil to heat up in such a way that each wrap lights up orange one-at-time, while the inner coil heats up last but very near the same time. It ‘almost’ worked that well, so I tried another variation.
The photo below is of the last barrel coil I will attempt to do until I learn more about this kind of coil. It worked pretty well and is wound with a 24 gauge Kanthal coil, ‘barreled’ with 26 gauge Nichrome 80. Its resistance was .2 Ω.
The photo above shows what the coil looked like before it was primed of its toxins. The photo below is not of high quality, however it shows the coil once it was primed.
The coil vaped fine at 40 watts. I wrapped cotton around it and left a hole in the top of the cotton for e-juice and airflow. It worked. Is this kind of coil worth the time it takes to do? That is largely up to you. For me, I prefer other advanced coils, even though these are fun to do. You can use them ‘chimney style,’ as I did with the Shark RDA, and they can act much like a coil in a sub-ohm tank would. Due to ideas concerning heat, however, I chose to install this one much like a normal coil. Here are a few photos of it while it was activated in a Baal V2 RDA.
As you may guess, vaping with coils like this one does not need cotton. They can soak up a few drops of e-juice for a 1-draw vape. I like to wrap cotton around it though. These are the first I have tried of “Barrel Coils” and really do not know much about the best way to make them or to use them properly. If anyone reading this has made them, before, please, let me know what you think. I am sure there exists a better way of making them, even if the one in the photo above was functional, after all. I may vape with it from time to time, however I will surely appreciate learning more about this kind of coil. Thank you for reading and let me know what you think.
