Rayon wick, better flow, flavor, saturation and Nic Hit!

Way back in ancient times (like a month ago?) someone posted links to two companies that offered rayon balls, one was Delasco and the other was MedSupplier. There was something about the Delasco site that rubbed me the wrong way, so I ordered from MedSupplier. Well, they suck.
...

I can vouch that the Delasco company works VERY well.
I received my rayon balls, here in Brazil, only two weeks after I got then in their site.
Working awesomely!

Thought I'd share my experience thus far. Been using the 44060 box of rayon with a magma and kayfun for a couple days now and am sold. First started just like cotton, same wick length etc, nothing special and it worked fine in both devices, but then a few million pages ago in this thread I saw mention of the tail thinning so I tried that and am VERY happy. So happy that I thought I'd try something with the magma I haven't done, and that's having only one tail per wick going into the juice well on the theory that less material in the juice well, the more e-liquid it can hold.

Here's a picture of my magma today, after vaping mint chocolate chip all day yesterday on it. I took a little more rayon than needed, twisted an end, and tried to tug it through the coil but wont go. So I string cheese some off until it does slide in (without twisting the wick), and the right amount seems to be where you I can feel the material actually gripping the coil as you slide it through. It's not that it's too thick, but I can actually feel the friction of the material gripping the coil. Snipped one side, then fanned out the other, and thinned it so it comes to a tip, wet it and got into the juice well. Performed great, and noticed for the first time I wasn't having constant issues of juice leaking out the air holes like I normally do. Maybe it's a fluke, I don't know, but the default design causes juice to pool up on the flat deck and any refilling normally causes me to have to blow out juice from the air holes, so make of that what you want. Today, the back wick is a bit gunky and still partially saturated, noticed part of the short tail was contacting the deck which probably altered it's wicking properties (that side of the deck had juice pooled on it, the front side did not, so I'm adjusting it so nothing makes contact with the deck or wall, will see how that goes).

As for my kayfun (sorry, dont have a picture), I had an interesting experience. Typical standard microcoil kayfun setup on that 45 degree angle. My first rayon wick was no thinning of the tails, and just like a normal cotton setup, saturated and stuck into the back of the deck away from the juice channels. Wicked just fine, never a dry hit. But, after hearing about the thinning concept and doing the magma, I redid the kayfun again yesterday afternoon with thinned tails, assembled and... was often getting dry hits. Slept on it, then today I rewicked it again with thin tails, but this time I attached the chimney without the top so I can see what it looked like after screwing it on, and what happened was the curved shoulders would literally grip the chimney and shift as it screwed on causing it to block off the juice channels. Using my small screwdriver, I re-positioned them where they belong and it's performing like a true monster.

So if anyone's having issues with dry hits on a kayfun, pay attention to the wick AFTER putting the chimney on, you may have a similar issue to what I did. As for the tails, I fan them vertically then thin it so the longest strands of the tail are on the bottom basically, saturate it, then work it a bit with my screwdriver so that it makes a nice wide-angle curve (which easily makes contact with the chimney wall, which is what causes the complication I had above when screwing in the chimney, and after re-adjustment it will still make contact along the wall, but it works so whatever). Interesting thing is, as I work the tail into a clean curve, it flattens a bit so it's no longer circular but more like a sheet of strands, which probably helps contribute to it forming a nice curve instead of a sharp bend. All I can say is, it wicks great and couldn't be happier.

Far as the health drama thought I'd throw in my 2 cents. I don't know how safe vaping with cotton is anymore than rayon (or vaping in general), but the risks are more likely inherited if you BURN the material instead the juice (not that I know how safe the juice vapor is either). I noticed on my dripper that instead of getting the cotton dry-hit "time to drip" hit (me and cotton was always either good hit, or dry hit, never a drop off inbetween, so it was inevitable), the rayon diminishes in flavor signaling me BEFORE I reached a dry hit. I feel safer with rayon because I actually get more dry hits with cotton, which I'm inclined to believe is the health risk part. That, and the common gunk buildup from cotton is probably not a good thing to be inhaling either, wouldn't be surprised if that buildup is more dangerous than the juice or wicking material. I prefer synthetic to natural anyways since it means a more scientific process goes into producing it (I avoid organic products of all kind, to give you some insight into my character). Just cuz something's more natural, doesn't tell me squat about it being better in any way. Besides, there's nothing natural about my e-juice, nicotine, batteries, mod, kanthal, or anything else in the vaping process. I also live off a DIY soylent instead of eating food the way nature intended. Yay science! Until I see studies that can CONFIRM the risks I've chosen to take, allowing me to reassess the situation, I will continue on at my own discretion. tl;dr: keep your wicks wet.

Oops right right. That's a 2mm id coil. And I actually didn't thin the tails at all; in fact I had completely forgotten that I "needed" to do it. Which reminds me.....

My tail at first was very big. The one thing I did do was spend a solid amount of time saturating the hell out of it and "pasting" the wick against the positive block before reassembling the kayfun (have I mentioned how much juice the thing holds?!) it basically looked like an upside down fan.

The other thing I forgot to mention was that after each of the first 3 tanks, I did disassemble the atty to check the wick and coil. Each time, the wicks got flatter against the positive block. So what I did was use a screw driver to push the wicks and kinda consolidate it towards the middle of the positive block. It's been looking the same after the 4 and 5th tank and I haven't touched the wick.

Kiwi, you must've seen this post too: http://www.e-cigarette-forum.com/forum/general-vaping-discussion/507143-focalecig-new-fasttech-171.html#post12518201 The way she explained it was what made it crystal clear to me. ;)

Oh I haven't! Following the FC thread is impossible :p

But yeah. Lately I've been favoring the straight down fanned out wicking more. Seems to wick better for my higher wattage vaping in a kayfun.

In any case, I'm still in the process of experimenting with rayon in the kayfun and have no clue what's the "right" way

K kiwi, as far as thinning tails it seems it is different for each atty and how you build it. I don't seem to have good results in a dripper is I don't thin it .. Obviously since a my dripper builds are thinned to a 1/4.

Whatever works! You know it works when the coils are clean like that so we know what your doing is working well for you. :)

Well, you know what my driper tails look like and to tell you the truth they are working just fine for me. I have decided against thinning them out on this go 'round. The Plume Veil has a very shallow well and I like to drip a lot of juice in it. The excess rayon in the tails helps me keep it from flooding.

Next time I re-wick it, I will give your thinning of the tails method a go though. Just to experiment and see the difference for myself.

Here's a picture of my magma today, after vaping mint chocolate chip all day yesterday on it. I took a little more rayon than needed, twisted an end, and tried to tug it through the coil but wont go. So I string cheese some off until it does slide in (without twisting the wick), and the right amount seems to be where you I can feel the material actually gripping the coil as you slide it through.

That looks very interesting. I have been using tails on both sides of the coil and although it wicks just fine, I don't seem to be able to get more than 20 drops in it before it floods out of the air holes.

Thanks for the tip! I'll have to give that technique a try the next time I re-wick my Magma.

By the way Kiwi, I had to change out some un-steeped really bad juice. So I did open the top part of the chimney cone and look in. The coil has like a "gunmetal" glaze (not gunk) and the wicks look nice and clean save a few black specs from sputter that I get at around 20 watts. Also the wicks are still filling the coil ID.

^ yeah that sounds like what I have during my last inspection, although I have noticeable gunk just starting to form between wraps. I don't expect the wicks to change anymore at this point in terms of the density or further collapse. Just gonna leave it alone for as long as I can. If it ain't broke, don't fix it!

Yea, 20 tends to be my magic number too though I got lazy at some point and just squeeze "some" juice in and go. How much, heck knows.

Was just a random idea, with the dark juice and closer inspection it does seem like the short tail sides are showing signs of some gunking along with those halves of the coil that I was not getting before, so it may be that not having flow from the other side may reduce the longevity rayon offers. I think I'll be going back to the standard two tails, with the thinned wicks it's at least a third less material in the well compared to cotton, and it wont expand, which realistically is more than enough. I'm more interested in longevity, been so sick of having to rewick daily with cotton.

It is cool to see how well this stuff can wick, I'm tempted to dig out an old genesis and see how well rayon works in that, but I've got enough in rotation at this time :p

And about how many hits do you get off of those 20 drops? I believe I get anywhere from 16-19. I thought that was about right as I take 5-6 second draws each time.

I've got people over in the General Vaping Discussion forum telling me that they can put 40 drops in and use it for a couple of hours. They say that they can fill it up, take it shopping with them and not even bring a bottle of juice. Really?! :confused:

They're using cotton so maybe it's just because the rayon wicks so well that it really eats up the juice which I don't mind at all as I am getting great flavor and some decent clouds.

That's the same stage i'm at.I thought i had finally gotten it perfect,as i dont get leaks or dry hits in my fogger anymore,but i am only getting maybe 3-4 days before my wick and coil are just plain nasty.A quick rinse cleans the wick,and then i have been firing it a few times to help dry it out,and that burns some of the gunk off the coil without hurting the rayon.Eventually i will change them both,but for now i know this set works good haha.I need to add though,i think alot of my fast gunking may be coming from the fact that the juice i am using has sweetener in it,which i have read alot that it will gunk them pretty fast.

Apologies but I never bothered to count how many draws I get out of 20 drops. At my desk I'll typically get half an hour to an hour's worth if it's the only device I vape on, but if I chain vape when testing stuff I can go through it in 5, maybe 10 minutes tops. Can't imagine being able to put too much more juice in there, just because the tilting to get it into my mouth can easily spill juice onto that deck which ends up in the air holes, which often happened even with 20 drops after I've broken a new wicking as the insides would have eventually gotten coated in juice from splatter. I'm sure the dremel mod would make all the difference in the world and improve it's capacity without air hole leaking, since it would be difficult for the juice to reach them.

.. I'm more interested in longevity, been so sick of having to rewick daily with cotton...
That's what initially got my attention when I saw this thread months ago. I was getting decent enough results with cotton in my Kayfun but I could really only get 2 tanks through it before I needed to rewick. My initial rayon builds weren't the best but I was getting equal results compared to cotton and could now go days between rewicking. But as more then more people tried rayon and kept talking about how much better results they were getting I was frustrated. Then someone made a comment about trimming tails like an arrowhead and it finally clicked what JeremyR was describing about the tails. I too always check the tail placement after screwing on the chamber and before the chimney and paste them back where they belong if moved. That first hit when I'd finally gotten the wicking right was just as good as everyone was saying.

So if you're trying rayon and finding its not very different from cotton, just keep trying. There are lots of pics and videos showing how to wick various types of atomizers to get those good results that are being described.

I gave up on my Rayon. I went back to Shisaido and could not be happier! Every time I build something I get crisp clean flavour, excellent vapour and it's hassle free.

I got tired of wicking issues after wicking issues, having to trim the tails etc...

Anything that shrinks when it gets wet which could lead to dry burns or wicking issues just is a 100% disadvantage to a fellow vapour.

Good luck with the rayon game guys! I'm out of this and I've had some of the best vaping of my life!
Russian 91 and Tainfun GT with Shisaido japanese cotton = perfect.

I have to agree that the shrinking thing is a problem that needs a solution.

I rewicked a i30 top coil, got 5 really great hits, then gosh awful burning in my mouth, throat and lungs. My tongue felt burned all morning. Top coil had wick collapse.

This is a 2.2 dual coil that uses very thin wire to get the 4.4 for each. I pulled a fat enough wick that almost ruins the coil.

Works great in my gennies with 30ga 5/64 coils.

I'm suddenly having a bit of a problem with this rayon wicking, and I'm not sure how to fix it; till now I've had very good results but this is puzzling me.

I put a new wick in one of my kayfuns yesterday, because the old one was tasting bad, and sure enough, it was pretty black. So the first wick I put in there, obviously it just wasn't enough rayon, it was giving me all that pop-pop-pop business. so I broke it down again, and did a whole new rayon wick, but this time using as fat a hunk of rayon as i could get thru the coil, and it wasn't easy, but finally by pulling on each end of it, I got it to slide thru. Once I got it all trimmed and primed, it looked perfect, so I put it all back together and gave it another try. I'm still getting this one huge POP! if it's been sitting for any length of time not being vaped -- like 10-15 mins; I have to press the fire button with the thing pointed away from me, let it pop, then I can take a hit; I can then take several hits, without any trouble, but once I put it back down and it sits again for 10-15 mins or more, when i first pick it back up and fire it, again I have to aim it away, let it pop, then take my hit. it's very frustrating because I thought the popping was from not having enough wick.

What is this "Dremel" mod for the magma? Got a link? I will give search a try also.
