I have experience with old genisis atomisers. The DiDs, Temons, and the Line LE. I have always wanted to try out an authentic Siam Mods Cobra. After searching online, i wound up purchasing two Cobras from LeGadgets. They are based in Malaysia. $160 and three days later, DHL delivered those two Cobras to my address in Ohio. All of the holes (5) on the deck are threaded, with grub screws. Center post is a long threaded flathead screw. Two jam nuts for the pos lead. To coil--i held the bottom jam nut with pliers, while turning the screw at the 510 connection--to secure the center post and keep it from spinning. In sciencing out a build for this Snake--i quickly realised that even though a 2.5 mm jig (same one i use for the aga T2) fits perfectly in the Cobra--the wick winds up being too fat, choking off wicking. I believe that the threading on the holes, coupled with the thickness of the deck necessitates a wick and coil with a smaller inner diameter. So here is the build that i have come up with so far--that wicks effectively without overwicking or dry-hitting: 5 wraps of 32g kanthal Wrapped around a 3/32 screwdriver that is 2.4mm wide. 2.0Ω 400 mesh 43mm wide by 40mm long--solid I use a tube mech mod to pulse it out and adjust the coil. Switch the atty to the Tesla Sub Box--unregulated with more power to finish adjusting the coil. 3.9v to start with on the Provari. Yeah, it's a good widdle tootie Snake. Tried 300 mesh. Overwicking big time Dropping a wrap on the coil to 4--dry hits if you take too long a drag Jam nuts--finger tight. The Cobra likes to bite off those leads. Famous for tight draw. But i love it. I will never take a drill to any part of this genny!!
