So now I'm really curious about trying 500 grade. Since wicking ability in this one has NOTHING to do with filling it/potential to leak, I might as well try the best stuff out there.
I did a fairly sloppy version of your build and its working fantastic! used 28ga kanthal and did a microcoil coming out to 1.6 ohms. Cant recall the # of wraps. 6 or 7 maybe. Wrapped the coil around a 1/8" drill bit and rolled my 500 mesh fairly loosely and clipped the underside of it so it would bend easier. Certainly not a round wick all the way around by any standards, and they may not be making as great of contact with the juice deck but dang dude its BY FAR the best build I've ever had on the Russian. Not a trace of flooding, and was getting slightly dry hits at first, but once the mesh got fully saturated, its working fantastic.
Most of us know that SS mesh tends to have a break in period, so I can imagine that it will improve. I had to give it a couple tries, because it was shorting like a wet basement with loose electrical wires. Lucky I'm not using a mech for that lol, my Provari was throwing error codes alot. I scrapped that roll of mesh and did a new one, torched it significantly more than usual and it works just dang awesome. I've heard whispers of mesh builds on kayfun style attys but never have seen a successful one on youtube or anything.
This is definitely the way to go for the kayfun style attys. Crisp clean flavor very similar to my RSST, with the capacity and efficiency of a kayfun. My RSST is a pig lol. On top of the fact that I can vape an 18490 in 45 minutes at 5.8 volts running a 2.4 ohm microcoil, I can drain 2/3 of the tank in that time as well if I'm chain vaping at my local vapor lounge.
Impressive young skywalker. Most impressive =]
