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

[atroph]

I have vaped a spaced dual coil setup for the past week and it has been outstanding! I think I have went through 15-20 mL which is pretty damn good considering this juice is a super dark and rich vanilla custard.

I am about at the end of the bottle and will rebuild this thing in the next few days as it is starting to get a sliiiiiiight burnt taste if I take a super long pull

Today:

Initial build after a few mils:

Edit: OOPS the above build is single coil mode. I rebuilt it in duals with 32 ga vice 30 ga shortly after this one. Same juice though so you can see the transition from fresh to not so fresh. I vaped the shizz out of this one.

I have a vanilla cola that is darker that the "used" photo. I may give that one a whirl in spaced mode as it funks the coils the fastest that I have seen in any of my other juices.

Another thing I would add is a thinner wire like 30 or 32 ga will heat up faster and will also cool off faster when you draw air across it. I just built a twisted 32 ga coil and takes longer to heat up vice single strand 30 or 32. It does allow for better control at higher watts though as the temperature swing is less extreme because the thicker coil retains its heat a little better.

Um. Well.

I was trying it mainly for the longevity part, so I don't have results for it.

But right now I don't really like it unfortunately. It just feels like it fires up noticeably slower than contact coils (which makes sense to me).

Might have to drop the resistance and get more power. Hmm.

Currently at 0.8 ohms on a fresh batt

If you make same coil but space it, there is now more juice cooling. So you'll find it needs more power. With a vv im able to just turn it up to the extent of the mod.

Coils have more juice around each wrap. It is a balance of power. More juice on each wrap needs more power. You can adjust spacing to match power and wicking coverage while avoiding a center gunking from a hotter spot & pooling on top. If you think about a micro has essentially a hot spot in the middle. Or hotter and we try to avoid hotspots.

If you give a very slight space just enough for juice to drain off it will cover less wick and heat faster per power. Spaced with just a needle did get me to 100ml with a density that was not too tight.

Each coil, atty, gauge, mod, juice, and personal vape style will add variance.

My duals right now are essentially the same as my parallel but over twice as much wick. And the cooling from all that juice on a super saturating rayon wick is noticeable. Some of my recent builds I think have been spaced a little far.

That's some of my thoughts about it.

Thinning your tail 50% at the 45 degree mark on the bend will reduce the dark back flow for you, and give greater longevity to your set up I believe.

Well, I haven't found myself in the sub-ohm dual coil situation yet.

I did finally rebuild my KFL and R91% with rayon and they seem to be working great and thought I would throw up a couple of pics for review.

I used 28 gauge A1 with a 2mm I.D. and a 9/8 wrap that put me at 1.5 ohms with CC wick.

Vape On!

Add-

I don't see any gunking on your coil..!.. Just looks like back flow continuing to get re-fired. (Unless the juice is that dark). Juice Going from deck to coil and back to the deck, R&R.... Are you able to vape the wick till dry and all juice off the well? My deck and tails are about dry before a redrip.. No back flow there... Thinned tails will do that for you. It also causes a more efficient use of the juice.

You could just trim half the tail at the bend soak up the dark juice off the wick with a towel, fresh redrip and continue going to see what happens.

Too late! I re-wicked it and dry burned the coil. There was indeed coil funking as it took a few dry fires to burn it off and glow evenly. I was starting to get "toasty" tasting hits and knew that if I kept it up I'd be in trouble. Never really drained the well dry and that could have been an issue. I always kept this one mighty saucy. No way cotton could have even thought of keeping up.

Same coil setup on a cleaner juice wicked as you recommended (as best I can). Off to the races again!

Next time Mr. atroph, you should try leaving the wick in place and just a tap water rinse I'll bet you could have gotten another 15 ml out of it.
I have had wicks that looked like that and after I pulled them and rinsed they looked almost good as new. But you can't push wet spaghetti back into the coil.

The next time I run into the "Black Funk" (if I can remember) I am going to try a warm tap water rinse just out of curiosity.



PS - Not to save rayon just to save time rebuilding. God knows we don't need to worry about running out of Rayon.

Been using KGD cotton on a flat ribbon wire build in a 454 for the past week or so. Dual coils netting around .6ohms. It has been performing well nothing to complain about, but I could not get nic'ed out on the KGD. Replaced the KGD with CC rayon today, a few pulls and I can feel the nic kicking in big time.

 

[Necrosis]

I wonder if there's an optimal ratio to tail reduction. My current fogger wick has roughly 90% of the tails snipped thin with the remaining going down into the juice channels. Pre-saturation, the remaining bits were nearly paper thin and maybe 2 to 3mm wide, and it's been performing great.

RSZ1, The NIC kick is pretty amazing did you notice any flavor enhancement?

Yeah mine are paper thin , thin paper that is. I think it really depends on the particular setup.

Jeremy,

You can be sure the Flavor Art did their homework before they posted their opinions without any caveats.

Yeah you know who works there?

A bunch of chemists!

I bet.

And they have no vaping rayon were gonna die concerns

I have been using CC rayon since early June. Another member here and I did a swap of CC for KGD, though I lost my sample of KGD up until about two weeks ago. I wanted to compare the KGD to rayon so have done so the last week or so.

I vape only unflavoured 100%vg. As for flavor between the two, it's hard to say. I find KGD to impart more of a sweetness to the vapor than CC, a more mellow vape all around. With CC I find the nicotine is much more pronounced, and the nic hit is way harder, hence more of a bite to the vape.

Best way I can describe it is, using the CC reminds me more of smoking analogues.

I have never used KGD (Goodness that sounds like some kind of STD) so I can't compare and when I switched to CC I had been using some pretty old Ready-X-Wick. Anyway when I switched I notice an improved mellow flavor and a little sweeter. However the Nic hit can still catch me off guard. Sometimes I get to watching TV and chain vape using CC... that's when the nic will hit like a mule kick. I chain vaped with the Silica but never once got kicked off the couch.

By the way I use 24 mg nic and when it decide to make itself known I will actually get a case of the sweats sitting under the air conditioning vent.

 

[atroph]

Oooooh yeah... The sweats. I know that feeling all too well. Lol. I am playing with dripping and have gotten to the point where I can spew some serious vapor. I am only using 6 nic and after about 3-4 decent draws I get that hot feeling. Kinda like a little reminder that "I'm good".

atrophy,

Ever since I got my "Seven 30" and an Omega dripper I have to be careful or I'll get hot flashes, the sweats... God it is like going thru menopause and I'm a guy. I am just not accustom to getting such volumes of vapor. For sure my seven 30 and the Omega dripper make my Provari and ZAP look like a baby's pacifier.

It's all Jeremy's fault him and his clever discovery of Rayon as a wick. I have to blame it on someone Jeremy and now that you are a famous vaping innovator... well you have strong shoulders. OK I'll put a little of the blame on "Rip Tripper" everything he makes a video on puts out clouds like and old time Train Steam Engine and out of envy I have tried to duplicate his results but I am betting he doesn't use 24 mg e-juice.

Exactly bro! That's why it's the bomb and nothing can touch it.

@ Holman

I just about died vaping 9mg at 24w on the clt dripper. It definately needs 6 or lower for me. I don't even see how you can vape 24 on rayon . That's like 36-48 on cotton. Maybe it'd be good for you to drop to 18mg. ?

Rip doesn't use 24 that's for sure.

Hey did you ever get the flash evapor clone? ? Man the thing is great it's holding its own against other drippers. Even tanked up with 5 ml it holds its own. The reason I believe is the coil position on it. It's directly under the mouth pice or tube and I mean only a couple mm away. Effectively there is no chamber, air comes in the chamber and has to go over the coil before you get it.

I know I should reduce the Nic level but I made the mistake of stocking up when MyFreedomSmokes was having there 125 ml unflavored sale and I do mean stocked up. I really got carried away. I am having trouble buying more juice with so much just sitting on the shelf. At the time I stocked up it seemed like the right level of Nic for me them came this guy with an idea to use rayon as a wicking material came along and fouled my strategy. I am going to buy some PG/VG no nic and mx what I have down to 12 mg and if that is too strong I will just cut that again until I get down to something manageable.

On the flash evapor clone no I didn't get one. I don't remember why I did have trouble finding one and while browsing "Tbev" or was it "AMD" posted some pictures of their Seven-30 and Fogger and I was off to the races... blew all my vaping toy money or the month.

 

[awsum140]

Yeah, that guy Jeremy really started something for me, too. The rayon worked so well in a Protank I just had to try an RTA, so I bought a Fogger. Now I have three more of them coming on Thursday. So besides the heavier nic hit, my wallet took another hit as well. Sorry, Jeremy, gotta blame somebody, it can't be my fault! LOL.
