Cool.. will try on next build.. :)
your first build does look close for sure and like bsoplinger mentioned, it does look a little close to the deck. on average, I have found about 1.5ish to be good. but the amount of cotton looks pretty good imo but maybe a tad to long

Thanks.. I believe the current spacing is around 1.5mm. I'll move it up to 2mm (fit a toothpick in the space) and see..

Right now, I am flooding and gurgling.. which is not burning, so a step too far in the right direction :)

with certain juices I have done in the 2mm range which also worked pretty good. as for the gurgling, have you tried to keep the same amount of cotton in the coil but reduce the width of the tails? sometimes from a side view, you can see the saturated width of the cotton comes up to close to the deck, this can produce the gurgling.

Current gurgling setup.. This is the chimney method with trimming the cotton about 4mm above the chimney instead of even. Sorry for not getting closer.. phone wont focus properly.

I've never had much luck with that method of putting on the chimney piece before trimming the wick. it's hard to get the wick placement right and hard to tell if there's too much cotton / too little cotton. works for some people, though, just not me.

I like to keep the coil diagonal rather than straight like yours -- it helps with the wick placement.

I basically just do the nearly foolproof microcoil method where you paint the cotton to the walls of the deck with a liquid dropper. basically, I follow this: https://www.youtube.com/watch?v=z7o7RFoTtw0

he doesnt really address coil height though. 1.5 - 2.0 mm seems about right to me.

Gonna try the diagonal way again.. Just got a cotton taste doing it that way.

hmm just looked at your photo series from the other page.

what diameter is your coil? and how tight is the cotton going in? looks like slightly too much cotton. I try not to twist up or compact the cotton...just keep it fluffy and able to thread into the coil without being too loose. I think too tight / too much cotton chokes the wicking action and leads to dry hits, just like too little / too short. length looks ok -- maybe just trim a tiny, tiny bit off the ends and get it up against the wall.

decided to try and make a coil that produced dry hits, what I found was the only way I could produce one was from a wick that was too thin, or not enough cotton. I also went the other way to see if a coil with to much cotton would produce a dry hit. after 3 attempts I couldn't make an overstuffed coil produce one. on my 3rd attempt I put in quite a bit, enough resistance that my coil moved to the side (i had to re-adjust it back)and about as much as I think anyone would attempt. although I didn't get any dry hits from these, I did find the flavor was quite a bit muted. so probably 6 different builds today, 3 with less then normal amounts that I usually use, and 3 with more then I usually use. out of all those, only 2 produced dry hits. these 2 were with less then normal amounts. the first less then normal amount I tried, was only slightly less cotton that I usually use, this vaped fine. it wasn't until I reduced further then I started to get a slightly dry hit. my 3rd time, I used a piece of cotton that slide right in, hardly no resistance at all. this after a few vapes was dry and nasty. when wicking normally, I use a piece that has some definite resistance as I slide thru, almost to a point where I think its to much. i then move wick back and forth slightly shearing some of the fibers away from coiled area. i do this until the wick slides a little easier, but still has some resistance. i only form the cotton before inserting into a coil and never twist it first. by forming, i mean just pressing it to form a round kind of shape. i tried this today with a coil that was kind of average, and that most use. it was a 2mm coil, 1.3mm above deck/ 28g/ 11 wraps, at 1.4Ω. use a provari@ 4.3v. as usual, my coil was installed on an angle, which makes the wick tails run sort of across and down the deck. my wicks are 1 inch in total length and after i saturate them, i place them before installing chimney base. different types of cotton can produce different results, i use cvs sterile balls and have found them to be the best for my particular set ups. i know i cant cover every aspect of problems, and i am sure there are some issues that i haven't accounted for. also different juices, and different geographical locals but i personally believe, for the most part, that if your getting dry hits, you don't have enough cotton in your coil. like i said this statement may have more to it, and i wish it were 100 percent true for all, but at least in my builds, with all my specific configurations, i believe it to be 99 percent true. these pics below are my normal looking builds

That's awesome you did that.. I too am thinking slightly too little wick and a combination of that and the NETs is causing it to clog and produce dry hits which rapidly burn the cotton. The build I have now gurgles, but hasn't burned yet, even at 15w and I used more cotton than before.. So I think you are on to something..

I agree Diver, that was good of you to go through all that. Interesting findings. I guess I always took the word of others who said too much cotton was a no no. Yet I never reached that point because I have never experienced a single dry hit in my Kayfun life. I just wonder how much of the vapor is being produced from the outer wraps as opposed to the inner wraps. Maybe we'dfind the innermost wraps of any coil we build sees little/no juice...particularly if we're chain vaping.

Might have to think about the reasons why because that is interesting. But as for the cotton, I think certain types require more or less, and I think the cvs sterile balls require more. I'm just getting used to the kgd pads at the moment and find those pretty different to the cvs cotton. So far with the kgd it seems like I have to use way less compared to the sterile cotton. And rayon? More is much better.

I wonder if a split wick was used if that would be a fair experiment. In other words, two wicks (one on each side of the coil) with the ends sticking in, say, the outer two wraps only...on each side. Have nothing on the inner six wraps. I wonder if that would produce the same vape.

And when I use silica, I am really stuffing it in there. On a 2mm coil, I run four strands of 1mm wick. If you do the geometry, that makes it 2.4mm across at the widest points. When I pull it through the coil I have to hang my fingernail over the trailing edge of the coil and really yank hard. It's stuffed in there. Yet it still hits like a freight train.

There are some things that may or may not matter, but I do them anyways. Like rinsing and drying everything before doing anything with the kayfun. In the past I have tried to do quick fixes in a build without rinsing and drying, and every time I have done this, it just didn't taste right. Also I always screw the top cap onto the chimney top. I feel this seals better then keeping the top cap attached to the tank and threading the bottom deck to make the seal between chimney top and top cap. Guess you can call them pet peeves.

If I ever get this to be a science instead of hit or miss I'm wondering how those $15 clones at fastech perform. The Ephpro and trobeca were fairly pricey.


@ Regan55. I got the $19 Kayfun Lite from Focalecig, $17 from Fasttech I think. It's got a greyish finish (oh well) and the afc is on the side like a Russian. Mine works really good. Only thing is the 510 connector is a little long. I loosen the top ring on my Vamo to secure it. I also have the new version 2 on order, looks sweet. It's $31. Has great reviews and comes with the Nano kit! Hope that helps. ;)
