Alright. Wicked her up and gave her a couple of vapes.

Gonna report back in a couple of days because I hate to be one of those "errrmmaaagerrdddd this is the sickest build" and I'm gonna attribute whatever I'm having to just plain placebo.

So it's essentially just a coil made up of 3 "sub coils", each made of 3 wraps touching each other, and leaving space in the middle.

Nice! Maybe I'll try this "Tri-Coil" style when I rebuild tomorrow. Did you use 28g?

On another matter, a follow up to my suggestion of adding a 'halo' of cotton in the top of the chimney (post #12445):
For about a week I've been adding the halo after rewicking and it's worked fine. Started wondering if it was really doing anything to reduce popping, so I left it out yesterday morning but did an especially careful job of rewicking. I got popping all day.

This morning I drained the tank and added the halo . It's much quieter now.

Yeap. 28 around one of those cheap screw drivers that comes with all those clone attys. Pretty sure those are around 2mm or 5/64.

Came out to 1.6 ohms after squishing the sub coils together. A little high for my liking. Currently vaping it at 4.6V, and it's. Hmm. Good. I'll post back to update. I'm very intrigued.

ETA: btw just a tip, try to coil those sub coils as tight as possible before fixing em up nicely by pulse firing. First time round I just kinda did it sorta right, and trying to fix it after sucked. Rebuilt it properly from the start, and it was a heck lot easier.

So. Haven't had time to wick and vape on this yet. But someone just entertain my thoughts a little.

I've never understood microcoils. At least the whole making all the wraps touch each other part. It was all part of the "everyone says so so it must be right" kinda thing. The only real benefit I can see is more efficient thermal conduction between the wraps, resulting in faster heat up time. I don't see much difference in resistance.

At the same time, doesn't it make sense that if the wraps are touching and kinda form an almost impermeable tube-like structure, there is actually less spots for vaporized eliquid to escape from the wick? Essentially it'll only be from the edges of the coil.

Dunno. Maybe someone can help me understand why exactly everyone says the wraps should be touching.

In any case, I figured ah why not make a hybrid. And so I did.



So it's essentially just a coil made up of 3 "sub coils", each made of 3 wraps touching each other, and leaving space in the middle.

I guess I just wanna figure out if that would give a greater vapor prosecution. Hnmm


ETA: oh in case anyone is wondering, it does heat up and glow nicely evenly throughout all 3 sub coils. I figured the semi-glow pictures would look nicer and give a better idea of how the coils look

^^ This was exactly my thinking too when I decided to make a 'standard' coil for the KFL..

- The concentrated heat under the coil was burning my juice, then my wick.

- There was less area vaporizing the juice, so getting less flavor.

- The vapor was 'trapped' under the coil, so less vapor.


Glad to see I'm not the only one questioning the 'micro coil' :)

An average micro coil produces more vapor then a traditional coil because of more surface area of coil. A micro coil will be a warmer vape with more throat hit. As for flavor, If you compared a 1 ohm micro coil to a 1 ohm standard coil, imo the micro coil would have a slightly better flavor just because of the coverage of coil. This is just my opinions and how I feel they compare but like everything else about these builds, there is not major differences between one to another. Also I do agree about tiny gaps between coils, when I look at mine up close, there are slight spaces

Just for clarifications. Are you distinguishing between a micro coil and a normal coil based on whether there's spacing between the wraps?

Because if so, that's where my lack of understanding lies.

Neglecting bulging in the wick, given the same gauge wires and same number of wraps, a open-wrapped coil should have the exactly same amount of surface area as a contact-wrapped coil no? Or am I being ......ed again and missing something :(

On a similar vein, I do actually think that given the way cotton swells when saturated, an open-wrapped coil would in fact have cotton bulging into the space between the wraps, thus giving an overall higher surface area.

Agreed.. the open coil would have more contact area than the micro coil.. Squeezing the coils has also never changed the resistance by more than .1 either..

What I meant to say was more continues wick coverage, as more coverage in the same section of wick rather then spread out. What I think this does is produce more vapor because the heat is generated in the area above air hole. I think if wraps are spread out its an overall cooler vape that doesn't produce as much vapor. Because it's a contact coil, it heats up faster as well. Overall it's a warmer vape with more throat hit and faster. Again as for flavor, I don't think it that much difference.

I think we are talking about different open coils here. Are we talking about a wrap gap of the thickness of 28g wire? Or talking about a standard open coil where you can only get 4 wraps across entire lenght of wick? I am comparing a micro coil (let's say 10 wraps of 28g) to a standard open coil where you space the wraps. Usually a standard open coil has large gaps in between wraps where 4 or 5 wraps is average. So that is what I'm comparing. When you talk about coverage between a micro coil and standard coil, the micro coil usually has twice as many wraps with a little smaller diameter, this is also why a micro coil has more coverage then standard. If you were actually talking about a micro coil that just had tiny little gaps between and calling that an open coil, then it's my bad, I was in visioning a standard regular coil.

Well, first of all, let me give kudos to you for being coil curious. I am definitely not. I started micro-coiling when they first came into fashion, and am sticking with it. It works for me.

Some observations for you.
1) Yes, part of the micro-coil secret, as I have observed, is that the closely packed coils heat up better. My eyes tell me that, but what do my eyes know anymore... I can barely see what I type, these days.
2) I seriously doubt that tight coils hold in vapor. You would not micro-coil kanthal to make a bucket to hold water, and the vapor wants out. No way the packed coils are holding anything in.
3) SuperX never, as far as I know, claimed it to be the best coil. He did, and I think correctly, state that it was easy, credible, and repeatable. If, like me, you hate coiling and wicking, a micro-coil with rayon is sublime. Easy in, easy out, and not that often.
4) Point your coil ends towards the juice channels, and you can use less wick. Wick is an evil necessity. Just enough to touch the deck. I do believe strongly that wicking has more of an influence than the coil. But, I can't back that up either.
5) Don't prosecute your vapor. You will just make it angry.

I see.. large gaps with thin wire... No, I'm (we) are talking about using the same wire and # of wraps, but leaving small gaps, not compressing them tight.

I too thicked the wick. And for the first time ever had flooding because of that? Yeah i had heard that here,

so I pulled the cork, <<<< took out the old wick and put in a little less of Cotton, flooded a little now the flooding is gone.

Maybe you too have heard that was said, that if you over thick the wick, you flood the Kayfun. <<Doesnt happen very often but maybe a little.

No. Cal.
Hate to interrupt this intelligent conversation, but HELP :). I have been having wonderful success w my KFL plus since I got it a couple weeks ago. (28 g. 1.4. Cotton build). Great and easy ( I was actually feeling a bit smug about how easy I took to this.......and then........

So I dropped my device. It seemed fine but the next day, I had juice leaking out from the air hole. I checked the coil but one of the "platforms" where the screws are connected had moved. I was able to get said platform back in place, re-built (1.4 etc.) and tried some cheaper juice (non-WTA..50/50) to run a test. No problem with that, so I loaded my "good stuff" (more VG) and am leaking and gurgling again. Not just a light drop but leaking lots out of the air hole. Also when I filled it, it seems that more than usual was coming out the top (as I have it turned over).

I had been fiddling with the air hole screw a bit. It certainly doesn't look like a regular screw. Maybe that is what it should look like. I remember reading about replacement screws a few pgs back, but I can't seem to locate that now (not even sure if that is the problem.

Anyone have a suggestion for someone who is no longer feeling cocky and is having trouble with leakage? Thank you!

How does a 8 wrap micro coil have more surface area than a 8 wrap standard (not squeezed) coil? Did it grow while squeezing?

He means a more combined singular surface area. Opposed to spread out like in an normal coil a micro coil has more (combined) surface area. So it heats up quicker and more even, like one big coil.
