Help. Cotton with rsst

[jkais3r]

So. I've had the rsst for a week or so now. Every coil/wick I build has burned. I use cotton as my wick. Does anyone know of a tutorial or some sort of guide to building a micro coil with cotton for the rsst? I don't think that my micro coil is bad, the cotton just keeps burning up and giving a god awful taste. So if anyone has tips for how to use cotton with the rsst I'd love to know. I usually pull the cotton up from the tank side of the platform, maybe I need to go the other direction so that my wick at the top isn't rolled as tightly?

I am using 32awg kanthal with a cotton wick. This is mainly a wicking issue that I cannot figure out.. I got it to work correctly with an awful coil, which I decided to re-do. But now the wick just burns up.

The problem is in the cotton being able to wick fast enough to keep up with your coil. What diameter is your coil and how many wraps are you using? I tried a 1/16" 8 wrap in mine and found that the cotton just couldn't keep up with it at all. Was constantly tilting. I switched to cotton because the SS mesh setup I had tasted like metal. Figured out what the problem was, (didn't oxidize the mesh prior), and wound up going back. Taste was much better, but still didn't wick like I needed it to. Then tried SS rope and found it to wick far better. Wrapped the rope in Nextel and got even better, but taste was a little off and took forever to heat the coil up. Then tried the rope wrapped in mesh and found the best setup to date. Now my RSST, (3/32"), and Ikarus 2.1 hybrid clone, (5/64"), are setup with SS rope/SS mesh combos... Very satisfied right now. No more dry burnt hits...

Is the cotton tight in the wick hole? You could have a vacuum issue. Try leaving the plug out. I make my wicks a good deal smaller than the wick hole so I don't get a vacuum effect.

I had tried just a teeny bit of cotton, where the wick hole still had room around it, didn't matter. I tried pulling the cotton down because the top was burning on my vertical coil, it still burned. So was definitely a wicking issue.

But yesterday I found a video of a guy building a horizontal coil, and just matting up a little bit of cotton under the coil and between the wick hole. It turns it into an "auto dripper" I guess. https://www.youtube.com/watch?v=kxDrHFoZbnw#t=856

I don't want to use ss mesh or rope because of the hexavalent chromium.

Hi jkais3r, I've been using a cotton micro coil in my rsst for a few months now. Without a pic it's hard to tell what is wrong. This is how I set mine up, what works for you might be different. For making the coil and wick I followed the instructions here http://www.e-cigarette-forum.com/fo...271-micro-coils-increase-vapor-flavor-th.html. I never had good luck with a horizontal cotton coil/wick, so I did vertical so it could wick from both ends. I slide the wick thru the coil and the left side tuck under the wick and into the wick hole. The right side go's under the coil negative wire and lightly gos in the top of the wick hole or touching the left wick and then go's in the fill hole. With cotton less is more. Hope this helps.

No offense but if you can get a piece of Kanthal hooked up to a Lithium battery hot enough to free +6 Cr then the bigger problem is going to be the magnesium burns you get from the battery long before anything you get from the stainless. It takes temperatures well beyond anything we see in an atomizer to free the +6 Cr.

In no way am I negating your concern with Cr but without citation I don't think we need to add yet another piece of ammunition to the stock pile the anti-vaping Nazi already thinks they have. All it will take is one trolling around here, finding this thread then tomorrow morning we're reading how we're single handedly poisoning everyone within a square meter with +6 Cr.

On the first picture it looks like you have cotton through the coil but on the second it doesn't. How are you keeping the entire coil wet without the cotton through it??

 

[scooterholic]

Take your fill plug out and it will wick better. With having a bed over the wick hole and the fill plug in it creates vacuum in the tank.

looks good. What ohms did it come out to? Be sure your coil is centered with your air hole.

Dry burning an ecig can get up to around 700 degrees. (http://www.e-cigarette-forum.com/fo...nt/31335-acrolein-vg-simple-test-results.html) Yes, old thread and not necessarily on topic, but he takes a temp reading of a dry burn.

And people oxidize their ss by dry burning with mech mods.

I cannot find the temperature at which chromium vi is created.

If you can cite a source saying oxidizing ss mesh/rope with a mech mod does not produce hexavalent chromium, I'd like to read it. But there is barely any information out there on the subject regarding e-cigs. What is out there seems to mainly be guesses at best.


Coil came out to 1.9 ohms. It's centered on the hole. I don't know how it's working, but when it fires the coil doesn't glow on the top the same as the bottom, where it is touching the wet cotton. Also I had to prime the cotton, but after that just tilting keeps it wet.

Thanks for the tip on removing the plug.

hey buddy I posted that video some time ago for people having issues with mesh. the way I did the set up in the video works really well but does require tilting to keep the cotton constantly wet. no matter what type of cotton set up you use in a genny this will be the norm. there is another type of set up with cotton you can also try. this will be with a vertical micro coil, keep a small gap between the bottom of the coil and the deck and don't use the fill plug. the cotton wick will look kind of like those snaps, you know those white little explosives that you used to throw on the ground and they kind of exploded, anyways the bottom part of the wick is twisted tightly to a point and the top of the wick is fluffy. the twisted bottom is about 2/3rds the length of the entire wick and should easily slide thru the coil and into the tanks about half way down, the top 1/3 of the wick is fluffy and should rest on top of the coil and maybe into it some, but for the most part the coil kind of cradles the cotton nest top. this set up works pretty good as well. as others mentioned the cotton, for the most part just cannot replentish quick enough for a genny style atty but does produce a good vape if it doesn't bother you to be patient. the best part about a micro coil & cotton is there is no heat sink effect like one gets from mesh and especially from a metal cable.

That argument has been put to bed quite a while ago... Here's a couple threads on the subject.

@vapdivrr

Thanks for posting that video! It was simple to do and I'd say works pretty well.

I'll have to try your suggestion of the fluffy snap type wick as well. But for now the little mat of cotton is working quite well!

"I just ordered me some SS rope and am out to find me some cotton balls until this matter is cleared up." post #624 2nd to last page.

The other thread doesn't really say much. So I'd have to say it hasn't been put to bed.

Who oxidizes mesh with dry burning? That seems like a terrible idea.

very cool. the ss rope works very well and does actually wick so its a great choice and similar to ss mesh, both great wicks for sure. for me it wasn't the chromium scare that made me switch to micro coils & cotton and bottom coil attys like the kayfun, its just a better vape imo. I really love the quickness & flavor of a micro coil & cotton along with the design of these attys.
