Ok I have to point this out. Stacking 18350 batteries when building sub ohm is a BAAAAAD idea!
18350 batteries have a very low maximum amp discharge. Going sub ohm on them is inviting a pipe bomb going off in your hand.
These days I only use the sony vtc4/vtc3 and the efest 1600 mah which is the same battery as the vtc3. If you want to sub ohm, these (imo) are the best, dare I say only, batteries to use.
With all the right tools, ok.. with the right battery.. cloud chasing is actually very simple. It is a combination of three major factors:
1) Coil resistance - the one you hear about the most. The lower the resistance coil, the more heat it will generate, the faster it can vaporize liquid.
2) Wicks - A wick that cant supply juice fast enough to your coil is going to result in a bad time. I know people swear by organic cotton balls. To be perfectly honest, even after building at least a thousand protank coils I still get that wick wrong sometimes. Its hard to use, simple as that, its a masters art. The easy way out, with zero expense of flavor or vapor, is organic cotton yarn. I use peaches n cream from walmart, ekru variety. It wicks sliiightly slower than the perfect cotton ball wick, but its consistent.
3) AIRFLOW! Nobody ever talks about this and it is a HUGE factor in vapor production! If you cant cool down your coils enough your going to end up with one seriously hot, burnt, nasty vape. If you dont have enough air to disperse the massive vapor production your coils are putting out, your going to end up with terrible clouds as well.
I own, and regularly use the IGO-W. It is a great little RDA, but the air holes that come on it are pin holes.. literally. You are going to HAVE to drill these out if you want clouds.
My favorite build is simple... ish:
- Twisted 30 gauge wire (read below)
I should note that the twisted wire is not at all like what they do on youtube with a drill. I take about 1.5 feet of wire and loop it over, then slot the loop into the clip on a pen. Grab the other end with pliers and start twisting. I do NOT twist until you end up with this crazy tight wire, doing so results in a massive amount of wire in a very small length, which ends up having quite high resistance. Instead, I twist until each... twist.. is about 1/16th inch long, I seriously use a precision flathead to gauge this. Using this wire your resistance per length is much lower than if you used
- 4 wraps on either side.
Simple spaced wraps, try to get them as evenly spaced as you can, as wide as you can.
- 1/8th drill bit
Actually a precision screwdriver works better.. but use what you have.
- 1/8th air holes
DRIIIILLLLL!!
- 6 strands of peaches n cream yarn per coil.
I make a snake /\/\/\ of yarn, where each / or \ is about 2 inches long. The three top loops I put over each other then use a small piece of kanthal to secure. Pass the kanthal through the coils and use it to pull the yarn through. Cut off most excess, leaving one loop on one side of each coil, stuff the excess under the coils, then cut off any excess that you cant get under.
This meters at 0.35 ohms.
Always ohm test your coils before you wick. Tap the meter to make sure your not shorting out anywhere, if the reading fluctuates, you have a short. Make sure your coils are not in contact with the pins, deck, walls, or cap of the RDA. If you short out, best case the coil pops, worst case... pipe bomb.
Good luck!
