I don't know why i'm getting more TH from the vertical coil build than with a standard horizontal micro coil :( I do my wraps with a 16g blunt tip needle i do 10 wraps on 28g kanthal comes out to around 1.1 ohms and i've been having the coils be flat with the deck unraised, do you pack the chimney with cotton and make it carto style?

In my experience with the vertical I immediately noticed my nic intake from the juice increased. I wanted more th , you can reduce your nic level since the nic hit is increased.

What mg are you vaping?

Do you think its over saturated?

I hate TH and i'm vaping at 6mg it's the lowest MG and I don't really want to mix juice to get 3mg or lower nic levels.. I don't think the i'm getting anymore nic hit cause i'm not getting a nic buzz and the vapor production to me seems less or at best the same as with a standard horizontal micro coil for me with added TH.

And I always thought over saturated wick is better than a drier wick. I did have an issue a couple times where I primer puffed the wick and it kept flooding and seeping out the airhole for a while.. I think that happened when I had the coil raised a bit. It's weird / inconsistent I know some setups it feels like little droplets of juice is shooting into my drip tip other times the taste is somewhat muted with more TH.

How you set it up will depend on the ohms of the coil, wire gauge and power.

I don't have a Russian but at the coil level it Sounds like you have your main core wrap too tight. That will mute flavor every Time for me. You want that wrap around the coil to be loose, to give the wick room to expand. If your packing cotton in around it don't pack it tight to the coil wrap it just needs to be lightly touching to wick to it.

If you use too much wicking it will be too wet to vaporize well. Depends on how much power your working with. If the flavors aren't popping you have something wrong.

If it were me I would use about the Same amount/ thickness of wick I used for my horizontal micros but split it and run one half down each side of the vertical coil with a core wrap of its own. Thickness of core Wrap depends on the power.

You may want to try raising the coil off the deck some.

Are you looking for better flavor then?

It sounds to me that what you are experiencing is a dry hit and not a hard throat hit. If the wicking isn't right or if you blocked the juice channels with some cotton, enough juice won't be able to saturate producing a harsh throat hit. That is why it is important to pull the tails up out of the way when the containment ring is screwed in. Also, to much cotton can flood the entire chamber.

On the single vertical I would have the bottom of the coil resting on top of the air intake. Make sure the cotton that you wrap around the coil doesn't go below the bottom of it and into the air hole, this could promote flooding.

I exclusively use dual coils on my vertical build so can't show the wrap on a single past what I have already posted. Find the dual a much better vape than the single, absolutely no sputtering, more forgiving on the wicking densities and more flavor. I also am using hemp fiber on my vertical builds now and I great for external wrapped wicking.

The hardest part of the vertical build is figuring out the proper densities and ways to wrap it. But once you figure everything out it is easy to do repeatedly. Your rolled stand should be fairly tight and dense, but thin enough to go twice around the coil without covering either end of the coil.

Sorry I can't be of more assistance then that and the old you just have to play with it till you figure it out adage sucks but is true. Good luck and hope you figure it out soon.

Use less wicking at the coil and lower power or higher res.

What pv are you using And what kind of juice.

I want more th so less is a little foreign to me. I know for a fact water cuts th @ 6-% or higher in vg. But then you need heavier wick at the channels to hold it back

thanks i'll rebuild my coil and tell u how it goes

Thanks for the tip, would I just use one strand of cotton to go around the coil twice to cover the long leg? I've seen a riptrippers yt video on the chimney coil he uses two seperate pieces of cotton he does 1 wrap around the coil then uses another separate piece specifically to cover the long leg, I was wondering if it's better to just use 1 long strand of cotton and wrap it twice around then I don't have to use two separate pieces. Am I suppose to fill the chimney / chamber with cotton to fill the gaps like I've seen a lot of ECF members do?

Both ways would work. I just like using one long strand to do the job, feel there is less chance of wick shifting issues that way. I just thread it between the long leg, wrap it completely around the coil then behind the long leg ending up in the same juice track that it started from. One of the reasons I prefer the dual series vertical build is that it eliminates the long leg and is much easier to wick correctly. A little harder to mount and build, but worth the added performance, taste and easy wicking. But then we all do what works best for us. The less I have to mess with something the better. My problem is that I keep playing with it past the best build. Then I have to go back to what was best for me.

do you have a close up of how the dual coil vertical coils build looks like over the air hole? i've seen some pics but I can't really zoom in so i can't really tell how the coil looks like since the image is too small :(

No I don't have any pics on my current build, but will take some next time I re-wick. I basically just did a 14 wrap of 28 Kanthal around a 20 gauge blunt nose syringe needle, then bent it in half and mounted it. It's the inverted V twin build, lmao. with the bottom of the coils about half the thickness of the screw head above the air intake. Pretty kewl build, the vape stream of each coil intersects each other and shoots the vape straight up the funnel tip producing a smooth flavorful Vape. So more of a diagonal build than a perpendicular vertical build. Looks kind of like this: /\ Not using the Russian much lately, been using the Aqua and Flash-e-Vapor V2 rba's as my daily vapes mostly, and have some Hypnotic Mary Jane juice in the Russian now, so still vape it, but not a lot. Put some hemp fiber in it a week and a half ago, so probably won't wick it again till the New Year.

Mary Jane ... Do tell! I've been wanting a mj flavor.. What brand... How is it?

I DIY now and bought the extract from eciexpress mixed in a dash of Hynotica liquor that I bought from Wizard labs. It's a pretty good vape but still tweaking with the recipe. But if looking for a premixed MJ juice can Highly recommend Super Skunk from Alien Vapor. This is a very fine vape, you'd swear it was the real deal.

When I bought premixed juices, Alien Vapor was my favorite vendor. All their juices were out standing from the first vape. Fast shipping great customer service. A bit higher price wise than MBV, but an excellent vape. Was waiting to get some of their Smurf Piss, but they were out, then started DIY and haven't purchased juice from anybody since. The Stoned Smurf was good, but had a Raspberry flavor to it, and it is blue. Go figure, Smurfs. lol. If you get an account with them, sign in, add order to you cart, then wait a bit and they will send you a 10% discount code to encourage completion of the sale.

Uh yeah you should have known I've been diy for 10 months. Lol.

I was looking at mj flavors on ecx before, my last hangsen tobacco flavor concentrates came from them, wasn't sure if you got FA hypnotic mist or the other mj flavors. Like the tfa brand which supposedly kona coffee is suppose to be added for skunkiness.

Super skunk sounds the bomb, if you can replicated gimme the recipe.
I'm thinking tfa mj and kona is what that is.

For a single vertical you can actually have the bottom of the coil resting on top of the air intake, and it vapes great. Raising it just increases throat hit and then flooding can be an issue.



I twist up the wick fairly tight, so that it passes through the loop with some resistance, then wrap it totally around the coil with each wick tail ending up in the juice decks. When I screw the containment ring on, I fold the wick tails up so as not to catch in the threads, then tuck the tails into the juice decks after the ring is tight.

I pretty much use a dual series vertical coils now. Vapes the best for me and much more forgiving on the wick densities. I thread the wick between the two coils then completely wrap both tails around the coils, with the tails ending in the same side juice deck that they started from, taking care to cover the entire coil surface without covering the end holes of the coils. Also folding up the tails while screwing on the containment ring. Think most wicking issues occur when the wick gets caught it the threads and block the juice channels.

So I tried the vertical build micro coil and ended up watching a tutorial video on YouTube to guide me along step-by-step. I ended up with 10 wraps of if I remember correctly 30 gauge kanthan which resulted in a resistance of 1.9, which is much higher than I'd like, since I really like to be right around .8 ohms. But I was willing to try it out anyway, the only issue I'm having with it is that it takes for ever to heat up, in fact I need to hold down the button for a few seconds just to get it hot enough to start producing normal Vapor. Besides that it turned out great, wicks really well, no hot spots, etc. but that damn delay is so frustrating it had me thinking I should try stacking batteries, but I decided against It in the end.

Hmm, I use 28 awg Kanthal for all my micro coil builds, even at 1.8 ohms there is no delay in heating of the coils. Never ever Stack batteries, a muchly dangerous situation in that configuration.

Try using a smaller diameter for wrapping your coils. What device are you using? I have found that with micro coils they all heat up dang fast regardless of the ohm's of the build.

What diameter, gauge, and wraps do you normally wrap to .8 ?
I'm running a 3 ohm coil ~12 wraps of 32 @ 10-15 watts and its good, no delay.
I actually like it better than 1.7 of 30g on the zmax.

Maybe your just used to a .8 and 1.7 is double that...

What kind of battery's , and mod do you use?

I initially built it at .6 ohms 28 Ga in my R100 with various densities of rolled cotton and it had good VP but the cotton would impart a funk to it in a day or 2 and kill the flavor. I went to cotton through the coil to dual cotton nanos to XC-116 to XC-132 to XC-132 with a mesh cylinder in the middle and some cotton filler to keep more juice density. It seemed all of these builds either had flavor deficiency, leaking problems, or lackluster VP.

Last night I wrapped 7 wraps of 28 Ga around a 14 Ga blunt tip syringe needle. I bent the leads vertically up and down and wrapped it in a long narrow strip of mesh. Juice burned it a couple times and connected it. I juiced and fired it 5-6 more times. I then stretched some boiled rolled cotton very thin and rolled it with minimal pressure between my fingers. I made 2 C pieces going from the juice well up around the mesh and back into the juice well. Primed it, squeezed the wet cotton closer to the mesh, then assembled and filled that baby.

WOW, best VP and flavor I've built so far and I've rebuilt this thing a stupid amount of times looking for the one. Im calling it the armored dragon. I'll post pictures later tonight. I can finally open the AFC all the way with no dry hits. No more covering the air hole to pull more juice in, no more leaking, no more poor VP, no more air flow obstruction. The juicy saturated vape I've been looking for. Cheers.

I'm using the magneto V2 with the sony VTC4 30A 2100mAh battery. I have the full Russian with polished tank rings for the atty.
