here's my latest build. it's vaping like a dream. i used premade A1 kanthal 28/32 UD clapton wire. 3mm ID, 8 wraps. comes in at .42ohm and vaping it on my Sig213 at 70watts with 80watt preheat for 1 sec. (anywhere between 60-80w it's been doing well)
cotton is somewhat firm through the coil, but i combed it with my tweezers and took out a fair amount of the density of the cotton.
then juiced up the wicks a little and then cut them a little shorter
put the deck barrel section back on and filled it up
here she is
another tip, toward the end when it's wicked, i like to use something small to poke a small air hole between the wicks and deck. i just use the tip of my tweezer and just push a little of the cotton away from the deck leaving a little air hole for the juice to breath and not cause a vacuum to inhibit the wicking process.
i hope this helps. i've really been enjoying mine. my favorite atty to date. i hardly use any more of my tanks and don't use any of my drippers anymore after getting this thing.
