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

[atroph]

Well I'll be. I have finally found a build that works well in my Plume Veil. I took notice to the nano dragon build a few pages back and remembered that I did a build like that a while back and just rested the coils on OC clouds. It worked fine, but my first mod maxed out at 11W and wouldn't power it just right.

Old coils saved in baggie:

So I tried that nano dragon in the PV and it worked pretty well. Pretty well until it dry hit. OMG!!! What a dry hit!!! No warning, no decrease in vapor, nothing. Just a huge lung full of scorched rayon! Yuck. I came real close to throwing that RDA across the yard.

I decided to revisit it again today and tried wicking the nano with Rayon. Twisted 30ga around a 20ga needle (0.90mm) 12 times. Net build of 1.6 ohms. Dropped it on my mod and did a quick fire. Holy cow this thing heats up super fast! I was concerned that it would get too hot for the Rayon to handle and it would be dry hit city. Pinched some Rayon off of my stash and slipped it in. Trimmed and fanned the tails out across the deck. Flipped the barrel upside down on the PV and let it rip. WOW! First hit was awesome! Normally after a new build the flavor is a little muted and harsh due to a flooded build but this one spewed like a locomotive and kept it up. So I went for the dry hit. Vaped and Vaped and Vaped. Still going like the energizer bunny. Finally vapor dropped off and that taste appeared. Not strong, just saying "Hi there, time to drip." So I did and whipped myself into a little nic buzz Oh and BTW this is only at 8W!!! I bet I would get super battery life out of this mod (IPV2) only vaping at 8W.

More juice testing to come, but I believe I may have finally nailed this darn RDA!

The build:

The tail closest to the wall is wrapped under the coil so that is why it looks pretty poor. The OCD in me wants to re-wick it to get it pretty and more efficient looking, but the realist in me says DON'T F WITH IT I stuffed the coil pretty tight with Rayon and the build held strong with little movement which is a huge plus as it irks me to have a coil open up or deform while wicking.

OK, I haven't mixed this flavor in MONTHS, but OMG Creme Brulee with rayon!

So here's something interesting (to me) in regards to my break in period issue with the foggers. I just rewicked one of them and decided not to scrape off the gunk on the legs like I normally would. All other variables the same, instant performance on the first hit. Dunno if it's related to the rayon, the fogger design, or my ability to coil (it's not, I've made over 20 coils now between these 3 foggers with over 250ft worth of microcoils under my belt), but definitely something that must be along the lines of hot legs. The break in time would be the the amount of time it takes to gunk up the legs apparently, which is a first for me. Wonder if there is some way to coat the legs, like nailpolish only less dangerous, would probably increase longevity between rewickings.

Now if I can figure out why this one fogger keeps gurgling on me. Vapes fine, not leaking out the air holes or anything, yet I can hear the gurgling as if there was juice down the air holes

I was expecting a bedded coil.... Holy cow you wicked through coil.

I guess the whole question of rayon and small coils can be answered.

Glad it's working for you!

You want a micro welder to make NR-R-NR wires. AMDTrucking regularly posts pics of his builds in the huge Kayfun lite thread and the big Fogger V4 thread. You can see the NR legs he welds into all sorts of coils.

Try "wet" burning with straight vg before you rewick on the legs... almost instant gunking [emoji16]

I got some Cellucotton samples from a fellow hhv army member. I just converted from silica to rayon in the Kayfun. I'm on my second tank now. It is all that you say. My ginormous box of forever wick is on it's way from Sally's. Great thread Jeremy, thanks for the work you put in on this.

 

[cindycated]

So I've been using rayon a lot lately, and I have a question that I'm sure was asked already (many times) but searching this thread is tough man, 600+ pages!

Early on people were saying stuff the coil more with rayon than you would vs cotton... now I've seen a shift saying not to stuff it so tight... now that people have been using it for a while, what's the best way?

Stuffed? Or not stuffed?

The rayon wicks amazing, I still get a little different flavor vs KGD... but maybe I haven't found the rayon sweet spot yet with wicking inside the coil?

My random thought for the day: it's easier to overstuff and pull a strand or two out later (easy peasy with tweezers), than it is to understuff and have to add a strand or two later (haven't been able to do that at all). And you know you have too much wick when vapor is leaking out of the airholes (in RBAs), instead of freeflowing out of the drip tip. If your coil is happily snapping and crackling but your hits feel empty and lackluster, watch your airflow holes and pull a strand or two out. But wait about an hour to see if the rayon settles first.

 

[XBarbarian]

yep. Rayon winz! I had tried going back to cotton on a R91 build last week... so muted! was very clear to me to stay with my big ol sally box!

 

[atroph]

Well this build didn't last long.

Worked perfectly until it was starting to semi-dry hit randomly even with a thoroughly saturated well. Figured the wick lost some of its properties and started to scorch in the middle. I dug in a box of supplies that I use to refill ink cartridges and found two different blunt needles. One at 1.18mm and the other at 1.59mm. These tiny coils are so nice to wrap and pack with Rayon.

Anyways off to test the 1.18mm coil I rolled. 10 wraps, 30 ga, net 1.6 ohms. Stuffed with Rayon of course!

Edit: Muuuuch better. The harshness started to return (slightly) so I turned the airflow hole to where it is not directly hitting the coil. I was also able to kick up the watts a little bit with positive results. Yesterday when I hit 9W I got a slight dry hit even though the wick was soaked. Now I jumped up to 10W and it was great. I think this wick might hold up a little better as it may be able to keep up with the heat that little coil puts out.

 

[JeremyR]

What mod are you using? How low in res can you go? Would be nice to get duals in there.

Next Time maybe just try to bed the nano coil. More in the middle. At least the coil would keep the wick down. Just an idea.

Mod is an IPV2 set at 8-9W right now. Hitting like a champ with loads of vapor and flavor. I have no problem doing duals once I determine if this tiny guy will hold up. So far so good, I chain vaped for as long as my mod would allow (10 sec IIRC) and it kept up just fine whereas the 0.90mm coil would start to give an off taste. I have some wicking issues right now as my tails are rather short and the juice likes to collect under the coil causing it to flood slightly. I'll rewick this sucker and give a little more tail to the build for juice control.

I have done the bed technique before so that won't be a problem if this tiny wick/coil setup doesn't last.

Edit: Well I had a little time on my hands before bed so I rolled a fresh set of coils. Lucky# 13 wraps of 30 ga. around a 1.18mm mandrel which nets a 1.0 ohm build. Wicked with the usual suspect. Had to fool with the airflow because direct flow would cause a harsh chemically hit. How it is now is kinda glancing the coils coming in at an angle. Loads and loads of vapor and outstanding flavor @ 18W. I don't want to push it any more as the vapor production is pretty stout, and I may scorch the coils. I have the bottom holes blocked off as they are leak prone and I don't really see a point once this deck is wicked. I did fool with the top airflow and it does seem to improve things somewhat.

Thanks for the push Jeremy and everyone else!

Build:

The longer portion of the wick goes to the end of the deck and wraps back. The shorter portion goes inbetween the posts and is cut so that it doesn't enter the other side of the deck. My main goal here is to keep the wick from the bottom of the coil and eliminate boiling. Looking at the coils there is empty airspace under them and IMO that works best for me.

Coil Airflow:

I'd thin / shorten those tails personality.

Glad to hear you are starting to have some success on the PV atroph.

I did fool with the top airflow and it does seem to improve things somewhat.

Good news here as well. I have mine wide open. The top of the delrin is almost flush with the top cap. Works great for me.

 

[JeremyR]

I never had any off taste with cotton but for some reason, I always used too much.

With rayon, for me anyway, I tend to get it right pretty much every time I re-wick. Probably because I used more than I needed with cotton (actually thinking it was the proper amount when it was too much) I think this is probably the main reason I like it so much. It is quite forgiving. If you don't have enough, it will collapse. If you have to much, it will choke.

Personally, this is my favorite wicking material although a forum friend (dice) sent me some Ramie in the amil so I'll have to see what that's all about before making my final call. But for now, rayon all the way for me.

I've had some ramie since I started this thread ... Good luck.

It's definitely grassy , and hard to work with. It sits in storage

ya, Dice is the only ramie evangelist I know =) but he's a self acknowledged madcap!

Yeah, I knew you tried using it before you tried rayon. We'll see how it goes. It sure looks like it would have even better capliary action than the rayon. If that's even possible.

 

[readeuler]

I went out today and treated myself to 500 feet of Sally's rayon, and promptly rewicked my dual coil trident RDA.

It's definitely too soon to know what the world I'm doing, but I will say 3 to 4 trial hits have given me a nice little nic buzz I haven't felt lately.

I'm also detecting some more subtle/slightly stronger flavor from a lovely lemon sherbet. Definitely no flavor imparted like cotton.

The real challenge will be rewicking the KFL, so we'll see how it goes later today!

I was blasphemous last night.... I got my 22mm Copper Tobh in the mail yesterday and just couldn't wait to put a build on it. Soooo I hit the wire that came with it (30g or 32g, not sure) with a torch and made a couple of coils... 15 wraps around a 2.4mm screwdriver... dual coil came out to 1.5 ohms total (measured on my Tesla... forgot and left DMM at work)... wicked through with rayon and dialed it in at 15W... makes a decent cloud on 20pg/80vg, but it's soooooo airy... it reminds me of Marlboro ultra-lights (I used to smoke Camel non-filters)... even at 12mg nic (usually vape 6mg) there is NO throat hit... this is were I'm calling the build blasphemous. I'm assuming that it'll hit better on a mech at sub-ohm (hoping anyway)...

Anyway, just had to share my disappointment... you may now proceed with your regularly scheduled programming!

The tesla is only putting out ~ 10w on average with a 1.5 ohm load. Maybe a little more with a fully charged battery. (Unless there's a new DNA based one out now) You definitely need more power. More air more power needed.
