Rayon Wick - Better Flow, Flavor, Longevity, and Nic Hit!! - Pt.2

[Sloth Tonight]

That's right around what a .6 ohm coil would produce on a mech. So that makes sense to me. A coil kind of inherently has a given range for wattage - as I see it - and going above that on a regulated mod is fine (probably to a certain extent, but quite a ways), but less just seems like it would be underpowered and thus underperform.

I agree a coil inherently has a given range for wattage. You know how I know it's underpowered? I puff & if I only get a wisp of vapor it's time to up the wattage lol!

I'm a large rda fan and would love to do a review and take it off your hands. To be fair I could trade a kayfun5 clone for it,just let me know.

Concerning the right power for a coil, it depends on the wire used, too. I use twisted kanthal 26 gauge. For me the sweet spot on a 0.45 ohm build is around 24w, which fails right in the middle of the power range for that build shown on vape tool pro (an Android app I use).

I'll run that coil at around 18w during initial built, while I'm priming the wick. After about 10 seconds of total time at that power I'll go right to 24 for my first real draw.

Thanks for the suggestions all. I'm home now but I can't really vape because there's this munchkin kid running in and out of my room. I did manage to increase the wattage to the recommended level and got some decent vapor and flavor out of this thing. No nasty liquid shooting out. Stay tuned!

Hopefully that's all it needed!

I forgot to mention in my other post that the coil is 26 gauge & 2.5 in diameter. I snuck into the bathroom for a couple more vapes and it feels good. Man if that's all it needed I'd feel pretty dumb especially with all the posts trying to help me out

Edit: Since I never thinned these tails, should I bother thinning them now?

The old saying applies...if it ain't broke don't fix it.

It's all good, as long as it's working now, like @awsum140 said if it ain't broke. How many watts is it now?

Everything I have seen scientific says there is nothing in second hand vape. Not my house not my rules but just so you know.

I run 316L, around 1.2 ohm, 3mm coil for plenty of wicking, smallish air flow, and run at 23w. SS will increase in resistance when heated.

I have it at 28 watts but the temperature protection is coming on. It's still very vapable. I'm tempted to just make another coil and try to get everything right from the beginning. Thin the tails, let it saturate good, and start vaping it around 25 watts and slowly move it up. I'll take a picture of my coil with and without the wick so you guys can take a look.

26 gauge SS316 inner diameter 2mm. Came out to .5 ohms. Nothing weird happened to the ohms when I put the tank on. I tried thinning the tails to 50%. Seems to be vaping all right so far.

Your going to surprise yourself how much and tight that rayon should be in the coil, tight enough just to the point of distorting the coil as your feeding it through and twist the rayon to get it through. Fluff or blow onto the end to look like a flower then cut 1/3 to 1/2 of the bulk off the underside of the wick several millimeters away from the coil. If you get a breakin taste then its wicked wrong but the taste does go away after several hits. Also rouge loose hairs laying ontop or around the build can cause taste.

I actually didn't get a break in taste at all this time. However, I'm still not quite convinced I wicked this thing correctly. I didn't make it as tight as I made the other ones. It was able to slide back and forth without too much effort. I'm getting slight juice coming up. I'm still trying to find the right wattage to use without activating temp protection. Temperature is set to 450F. The flavor and vapor is pretty good. This is lightyears beyond what I've been getting over the past couple days so I'm going to stick with it for a while.

Edit: Had the tank (Engine Nano) filled up about half way. It flooded when I filled it all the way up *sigh* Back to the drawing board.

Edit 2: Just wanted to say I really appreciate everyone's help on this. No one has been a condescending .......... Nothing but good people trying to help out Herrick. Thanks!

The rayon shrinks some unlike cotton that expands. It may shrink ever so slightly but if you can move it back and forth now when its dry its going to settle a bit in the coil after its juiced and be even looser having a gap along the top of the rayon and the coil, maybe to why its spitting. I don't think you can put too much rayon into a coil, its removing the bulk of the tails, how much to remove and how its cut is IMO most of the trick to rayon wicking. After its all said and done, you've vaped and toasted your rayon build, after rinsing to begin to clean the atty the rayon should be a hassle to get out of the coil, if it removes easily then again IMO it wasn't wicked tight enough.

I should add that I only use kanthal, spaced coils and have never dabbled into other wire types or temp control so talking temps is way out of my realm.

I thinned them about 50%...maybe a little more. I even tried not thinning them at all. Either way, the Engine Nano floods. I had a little flooding with the Merlin RTA but it's been holding up so far. I didn't thin the tails at all.

What generally causes flooding? Too little or to much wick? Or both?

I'm glad some of the guys are helping you, and it's nice to have someone who has that tank too I hope you get it to where it works great for you
I get flooding when I have too little. I got a tank a while back, the conquerer mini, and it kept flooding on me. The problem was I did not have enough rayon, nor did I have it sticking out of the deck enough, and I needed to raise my coil. Every tank is different, but my most common problem with flooding is I need more rayon and having the wick placed properly.

I don't have that tank but flooding is basically a common factor no matter what tank you have. You may have created a airlock while filling so adding juice is just forcing the juice out the bottom. My TFV4 did it if you didn't remove the juice film that was on the fill port ontop and kayfun also if you used too big of a bottle tip and didn't allow the air to escape while being displaced with juice.
There is a hole or the wick isn't completely covering the juice flow so again as your adding juice its going to flow out the easiest way, wicking can be disrupted or shift as your taking apart to fill.
I had a look at google image of the Engine Nano(looks like a nice atty) and I tend to lean more to you creating a airlock maybe with juice film covering the fill port but I'm just guessing. Maybe a thin syringe needle or a needle tip cap could help or blow or blot out the fill port before you fill.

The fill port is pretty massive, I can't see how you could possibly airlock it.

I fill my OBS tanks with 120ml bottles.

@Herrick , your coil looks good. As @AlterUrEgo said, wick it tight in the coil.

I see you're using an Evolv DNA mod in TC which is great. I have seven of them and have a recommendation for setup in TC.
Don't try to balance the temp and wattage settings for tc, just set the wattage higher than needed and let the mod regulate the power up/down as it sees fit. Don't worry about the mod displaying the "temp protect" message, all that means is that you are reaching your set temp. DNAs have extremely fast processors so you run no risk of your coil temp rising above your temp setting.
For your build I would set the wattage in TC to 50w and leave it there; that's plenty of power to reach whatever temp you choose and will help your coil ramp up to temp quickly.

Here is a useful tool for coil builds. I have entered your coil specs into the link for you.

An excellent explanation and all true imo too.

After its all said and done, you've vaped and toasted your rayon build, after rinsing to begin to clean the atty the rayon should be a hassle to get out of the coil, if it removes easily then again IMO it wasn't wicked tight enough.

I evaluate my wicking density the same way. I try to remember how the atty behaved (vapor production, spitty, popping, dry hits etc) and how many ml of juice I vaped on the wick WHILE I remove the wick.

Did it just slide out? Under wicked.

Did it offer a little resistance to remove? Better but still under wicked.

Do I have to grab a wick tail and twirl/spin it in the coil to remove it? Pretty good but still could use a little more.

Do I have to twirl/spin it by the wick tail AND brace the coil on one end with my thumb nail to pull the wick? Perfect!!

I can then make sensible changes to the wicking density accordingly.

I'm sure @AlterUrEgo and I both would rather not harp on this whole "wick it heavier in the coil thing" but it seems to me that 99% of the complaints about nasty flavor, spitting, dry hits etc are because of under wicking with rayon. Wick it chunky peeps!!
