It was Time to Rewick
Sophia Microcoiled and Cottoned...
Hmm, I had to do this build since I only use Microcoil and Cotton on all my attys nowadays. It gets easier to maintain (just dry burn and replace the wick once a while), which makes it hassle free in the long run. Besides, the VTF stands to get doubled making it a more efficient build. And I knew my Sophia would handle this very well. And man, it sure did!

Tip: You must see this movie if you haven't already√
1. Old build removed:
The build section disassembled from the tank and ceramic cup pried with a screwdriver to dislodge.
2. Ceramic cup Removed and Cleaned:
Standard kitchen dishwashing liquid used. Rinsed under running lukewarm water.
Step Up
Tip: Stick thru the video... you'll be amazed√
3. Microcoil made:
28AWG Kanthal, 7 wraps on a toothpick, 0.9Ω. Heated up and squeezed. The ends are kept short ~ for attaching NR legs. Multimeter checked.
<Very Important
√
4. NR legs attached using a Wire Welder:
Picked up the microcoil in a toothpick, ensured that it was flushed against the +ve Spring Post while touching the NR wires on it's legs. I used 30g Nickel over 28g Kanthal - and it surprisingly worked.
5. Final look of the coil:
Positioned the coil inside the ceramic cup ensuring the -ve leg got wedged between the base walls.
6. Positioning and placement of the build:
After test firing the coil took a thin piece of cotton(ball) wick and inserted it. Note: The cotton should pass thru with minimum resistance. That is the right size of wick. Too thick ~ there'll be dry hits. Too thin ~ over wicking, gurgles.
7. Wicks cut and tucked-in:
Screwed-in the body tube to cut-off the wick tails... opened it up once again and tucked-in whatever cotton was left under the base.
8. Coil and wick test fired:
Juiced up the build and tested.
Remember it is cotton ~ moisten it well before firing the button. Else, it'd burn... cotton is not fire resistant - unlike our Silica and Ekowool.
9. Assembled the Sophia:
Put everything together, opened the juice control a wee bit, let it sit for a while (observed the bubbles running upwards!) and got ready for the renewed experience.
10. Oh yeah
!
...The first inhale was a renewed pleasure indeed. And the first exhale ~ vapour production at it's best!
11. Yes, the Fire Alarm RANG!
...Subsequent puffs fogged it up nice and proper!
End Note:
It's about 24-hrs now that I'm exclusively using this setup. Was at work y'day night ~ thus it pretty much was used non-stop. Sophia is holding this microcoil and cotton build very well. In fact it's acting as a force multiplier. I'm firing it with a
30Amps Sony and the VTF is amazing out of this li'l fella! As you can see from the images I haven't opened the juice control as much as I did with my earlier build ~ and yet there's absolutely no stopping. Feeds right, wicks right and vapes right. This is a setup I can wholeheartedly recommend.
BOTTOMLINE:
Don't be fooled by the humble diminutive looks of this tube RBA...
This teeny-weeny is very much capable to blow your socks off
!
Thank you Leo for an outstanding device!

CAUTION:
It's not your ability to make sub-Ohm coils ~ what matters most is what batteries you use to run it. For sub-Ohms you must have 10Amps or higher discharge rate, else it could be disastrous. Higher the better ~ eg. the 30Amps Sony linked above.
DISCLAIMER:
It is recommended to use a coil having resistance of 1Ω and above. Sub-Ohm resistances are not recommended for any user of any device. Because, not every battery currently in the market can safely sustain / handle such loads. Even an experienced user cannot always be certain / confident of the Amp limit of his batteries.
