It all comes down to the quality of your product have to say wl is better and not better than others. I use 3 diffrent brands and some work better than another due to the quality of your product you have. Just my 2cents.. check out wax liquidzer post for some info as well
So that's why I'm thinking multiple donuts stacked lower at the floor, to be closer to the oil. 
This had been sitting in my shelf waiting to be vaped for too-long a time, so maybe it was less viscous when it was new? Maybe a chemical reaction with the silicon container thickened it? Perhaps it was this way all along? Who knows? I got to filling it in the syringe.
very smooth and substantial at low temps! 
It didn't taste bad, but just not a whole lot of good. Clearly, this is the fault of the (old?) co2 oil I had fed to this new coil. Plenty of smooth, repeat, rapid-fire vapor, just not much flavor on the input material to really let the potent coil shine. (I use donuts rather than metal coils primarily for flavor and longevity)
![:\](/i/s/hmm.gif "Hmm :\")
It feels like it's making more vapor than the double donut coil, and I think it may be performing better at low tank levels too. After making this coil in early January, I puffed this tank low and re-filled it with my final 2 half-g pucks already, and it was doing well at low fill levels even with this thick oil.
And this success has spurned me to plan triple donut coils for some of my other cubi as well.... 
Only 4%? With such a small amount maybe you can get by without that? But maybe you've tested enough to know better than me, with the vape710 carts. I've heard good stuff about those. I'm skeptical of leaking with those, with bottom air, but with a thick oil and some luck and discipline, I guess you've managed to avoid that? 
Hey all my tank people and coil builders,
It's been a while since I posted here, but that hasn't meant my various tank projects had been at a standstill.
After enjoying great success and enjoyment with the dual 10mm donut and quad 7mm donut builds with the RBA coil on the X-baby tanks, I wanted to do something to keep my many beloved cubis pro mini tanks, which I've continued to use, to be relevant and competitive.
The solution?
Triple 7mm stacked donut coil on the cubis RBA coil!
So my original donut coil, the stacked, donut-on-top-of-donut coil, using the default cubis BF coils, drilled with holes in the case for extra oil wicking, had worked effectively and faithfully for me in 4 different tanks with different oils, with both high and low resistance 7mm donuts. Perhaps the main design drawback I noticed is that when the oil level on the tank was lower, 30% or so, and the top donut and wick was dry, vapor production could plummet significantly, and taste could suffer if you repeatedly dry-fire that top donut without swishing the tank to get it wet again.
My first cubis tank available for this build was my trusty pink / red eleaf pico pair. It has vaped a respectable 5 grams, in 4 refills, of that thick sticky "california sap" co2 oil, and it's tank level was getting very low and the clouds had become pretty wispy on the near-empty tank. I didn't have any more grams of that brand or a similar oil to refill with, so it seemed like a good time to break this one down, clean it and get it ready for the new coil.
These "RBA" coils for the cubis are a little larger in diameter, and have a screw-open top to give you better access for building. I used this coil case for my first attempt at a cubis-donut build, but using only a single donut, floating high in the middle of the case with a poorly-placed cotton swab, (not really knowing what I was doing at the time) that first build 2 years ago was a failure and a let down...now I know more what to do...
Looks like coil calamari. Just to show you how all the wires are routed before they are cut.
Three of the wires must contact to the outer metal case for the negative current, the other 3 wires go in the middle, to be separated with the silicon plug for the positive flow.
Snip snip snip, make sure the negative wires touch the case solidly, the positives in the middle are ready for the plug
And then ready for the metal pin to seal the bottom.
Coil all built and sealed, a side view lets you see how all those donuts are as low to the floor as possible.
A strand of readyXwick stands ready to be inserted. And yes, extra holes are drilled in the metal case, 4 on this one.
The other side. All 3 donuts make a bit of a tilt on 1 side, and the wick shows prominently on the lower side
Loop-de-loop. All ready to test-fire and fill up the tank.
The vaping contents for this sub-project will be some half gram pucks of a thick, viscous co2 oil "wonder og kush" strain.
I took the little silicon jar and heated it over my volcano to melt the co2 oil and it took up to my syringe without much trouble. But for the next puck of co2, being so solid, I realized it was just easier to remove the plunger from the syringe, take the solid puck of oil, bend and shape it to insert it whole into the syringe tube, and just fill that way without having to heat the whole jar. I started the fill with 2 0.5g's
Thick stuff, dribble down. I did some more volcano hot-air-blasting on the tank to warm things up and help it settle down.
I fill the tank through just 1 side to minimize oil wasted sticking to the top
All filled! Silicon sleeve removed for this pic
Final coil came in around 0.42Ω with 3 high-resistance donuts. Using 42w, it warms up to temp in under 2 seconds, my standard goal. (it says 12w on the screen as that was last watt output during the last firing)
TCR 245, standard for the small donuts. Temps in the upper 300's made the clouds come instantly with the well-drilled & wicking coil
Clouds were very nice and voluminous to start,
The let-down? It didn't taste very good! Tasted like not much at all, a very mild sweet-kushy taste, but just not much there.
How bout a few more tank pics?
How the oil settled in the tank after a few puffs...
Peek down the barrel, I see...wet donuts!
So I'm declaring this new triple donut cubis coil a success, despite the flavor letdown in the co2 oil I used.
This 3x small donut coil is also more battery and small-mod friendly compared to my bigger x-baby RBA tanks as well. It only takes about 10 amps at the coils, which is fine for a single decent 18650 cell. I'm even logging 120-140 puffs on a full charge, between charges, with a VTC5, not bad!
So I'm just keepin' puffin on this pink triple donut tank, looking forward to it being empty to I can fill it with some better, tasty co2 oil.
Coming back here very late on you PPN, but you can use the pre-set TC-SS mode on your VTC mini and it should work fine on the ceramic coils for the veco. You can try Steven's TCR 140 for a slightly more accurate temp on the screen, also. (Pre-set TC-SS mode is ~120)
Then you want temps in the 400's F (low 200's C?) and about 25-40w max in TC and that should help those little coils fire a little more reliably, without running the risk of overheating the coils and getting burned hits.
2 months later you're probably not even using your veco any more?
Also getting back very late here, but the 0.3 or 0.5 ohm ccells are very similar in performance, but the 0.3 will just use a little more battery. They are essentially the same, the 0.3 only has a thicker SS wire gauge wrapped inside the silica ceramic cylinder, or less loops of it.
There are more holes on the veco devil, but they are more narrow and restrictive, and all the holes do not reach to the bottom as you note. With the type of thicker fluids that people like us are trying to fill these tanks with, I would expect that to severely limit the performance of this tank with concentrates. The regular veco is already significantly wicking-hole limited, IMO.
CYarbs! Nice post to introduce yourself! Great that you have a formula and set-up that works for you.
The one thing I find somewhat odd is how you use PG in your mix, but so little?
Ok, getting silly here, sometimes I overthink these aesthetic issues. We're going with the new crinkle black tank
I even have the air throttle open 2 or 3 / 5 holes open, huffing the drip tip pretty hard, and I haven't gotten any oil bubbles on my lip or tongue at all, after a couple hundred or so puffs! There is no ring of spit oil underneath the drip tip when I pull it out and inspect it, so that's a big relief and success. (going wick-free here)
you can also reach out to me to build some coils for you also 
Thanks @Accept
. Most oft the time i use my standard concentrate mix with PG/PEG in chamber 1 and 80/20 VG/PG nic juice with 1.5mg nicotine in chamber 2. The coils and diameters depents, but mostly i prefer standard ss316l 22ga with 2.5mm ..may 6 wraps and cottonon bacon "prime" and a 4x ss316l 300 mesh rolls (inside the chamber). i use the ehpro fusion nearly allday... since we tested here
I'm not going so fast through devices, I still use my Veco paired with the tiny mod which comes with the Dabstorm 2.0 from Vapefiend. Still work well enough for me and I'm still using my first ceramic heater, vaped around 3-4g of my homemade mix (winterized reclaim,PEg&terps and nic juice), this is my vaping joint (EU style) at work, medicates me rather well but only get through 3-4 puffs per day in average.Coming back here very late on you PPN, but you can use the pre-set TC-SS mode on your VTC mini and it should work fine on the ceramic coils for the veco.

Not fake-tasting like perfume or processed food additives
amazing!!!.....(but with one problem!)
The taste of the kosher kush HTE was so luscious and strong also, even for being old terps! I took about 15 or 20 puffs over the course of several minutes, and I felt like I was hitting myself with sledgehammer blows of kush! 
I was getting super blown away like i hadn't been in a quite a while, and I found myself pacing around in existential crisis mode "damn i'm high" 
haha
(arg) 
If I puffed moderately, this was avoided. But if I puffed real hard, I got even moar oil splits! 
Closing the air throttle helped, but you still had to avoid fast-draw puffs. I eventually adapted to a "MTL" or cigar-like draw on this quad rod tank to reliably avoid spits, and the problem receded even more as the oil level on the tank got lower. But it was almost always possible to induce a spit by puffing hard, and this is unacceptable to me. Damn, well I vaped this tank down to empty so I can clean it, break it down & add that top wick...next time?
with one of my new triple donut RBA coils (that one can get sticky if you don't wipe it often) Major bummer, being that I even test-fired it first, and had success using the same method building three different triple donut coils on cubis tanks myself.) looney is all set up with my latest cubis build, puffing strong! 
It seems good in how it supposedly can work well with a low oil level too, and also can work in TC modes, is leak resistant, and you can even change coils without touching the juice / oil in the tank too. Not bad. I've been tempted to try one out just out of curiosity, but restrictive air is a turn-off to me, plus I have way too many tanks going right now, and knowing it's 'just another ccell' I can't imagine it will taste that great.
ccell is just a generic phrase for a hollow, porous, soft silica ceramic cylinder with a metal lead wire coiled inside that ceramic, with lots of exposed surface for the metal coil to directly contact your oil. They can vape decently, but also impart a noticeable metallic aftertaste, which is absent when using alumina ceramic heaters with solders instead. 
Their porous nature tends to foul flavor with reclaim more quickly over long term use, also.
I'm thinking I will at least need a larger external battery charger, and if the larger cells require it, something that is compatible with them as well.
It is relevant to that topic, obviously; you don't have to start a new thread but welcome to if you want. The topics and conversation on these sub-forums aren't tightly controlled and are pretty free-wheeling. People get distracted and off-topic all the time, and the same questions and answers (and mistakes) are often repeated in many threads / places on this FC forum. I think alot of people can avoid mistakes & problems if stuff was more organized, but it's also incumbent on people to do a little research sometimes instead of expecting all the best answers to be delivered to them on a platter, at their request. And the payment / shipping / negotiation process seems complicated and opaque, so I haven't tried that yet...but you would get a much better deal potentially if anyone wants to go in on a 1,000 pack of donuts with me and split em up 
Geez man, you're already working on the next one... it sounds good too.
As I retire and gift the VTwo Mini's and Cubis Mini's (gotta replace the readywick for the previous atomizers), should I look at this Wismec rather than the Invoke?
I've got the 2nd SMOK tank waiting (I'm LOVING the 1st one), just saving my pennies
30A in the palm of your hand, pretty mind boggling.
I don't think your vaping needs really require dual 20700 batteries, but they sure don't hurt. Not really needing 30 amp CDR x 2, you can also get 4250 mah, ~18 amp CDR batteries, times two, it's still plenty enough amps for most any atomizer you'd pair with it, and 8500mah could last you for daaaays, even with the hungry QQ.)
I still don't know the exact difference?) But as long as it works good in the tank, it's clean, and it gets you medicated, that's what matters! It would be nice to see them back in the market, hopefully with 70%+ potent products soon! Competition is good, and I think our state market is in risk of becoming captured by a limited oligopoly for certain cannabis products. Let's hope that doesn't happen. It's not hard to keep clean, really. I've been trying too hard to get the last marginal puff too much, getting a dark crusty in the middle almost every time. Maybe I should sacrifice that last puff for easy swabbing.
Hi Tom, nice to have you with us, no worry on the drizzle love-fest on that other thread over there.
But OTOH, when you have some threads dozens+ pages long, with lots of irrelevant messages & old info, I understand why people may be deterred?
Anyways...drizzle! I did see your pics, right on for posting that, it shows well how low your oil can go.
Can you even get clouds at the lower oil level, or is that dry? That's about as low as my SMOK RBA's will go, (I'll vape mine to even a little lower) but lesser cloud production and gradually drier wicks occur when you try to vape with oil that low, so I usually refill before that point.
Also, you say you lightly grinded / opened up the sharp corners on the outer, metal chimney on the drizzle tank? To help the oil flow to the inside, where the coil is, more easily? Interesting...quite bold. Where you able to achieve clouds with low oil levels in your pic also before you smoothed out the big holes?
I just want to caution you, you do not want to drill new holes in the metal chimney of the drizzle tank (or veco tank) because you will break open the jacket to the air path, allowing your oil to get in the airflow which is supposed to be separate, and it will allow oil to leak into the bottom of the airflow path, underneath the coil. I found this out the hard way with my failed attempt at drilling a hole in the veco. Since the top-airflow path and position of the atomizer coil is pretty much the same on these 2 tanks, I think you would have the same fatal problem if you did add holes. (glad you didn't repeat my mistake here)
I get my donuts from divine tribe (ineedhemp.com) They can also be bought at "fat daddy vapes" but only DT has also the larger 10 & 13mm donuts, as well as the new, proprietary ceramic rods. I've also seen you can get alumina ceramic donuts (and TONS of different interesting sizes & shapes) in BULK thru many vendors on alibaba...directly from the factories in china! But they usually make you buy at least 1,000 or so pieces, minimum
No donuts at fasttech....but I did come across these interesting (alumina) ceramic cylinders. Bigger than DT's ceramic rods, the size on these look like they will barely fit in my larger cubis RBAs, probably the smok x-baby RBA as well, but I don't think they have an ideal shape / size for that tank? Gotta test fit to see....
They have solders, supposedly tungsten leads, and can be TC'd, so I have some coming in for yet another experimental tank RBA....
That leads me to the last thing I want to drop on you now, Tom...
temp control!
I see you're using an old 50w eleaf mod, that's a little better than an un-regulated vape pen, perhaps, but not much. Even with the proper watt setting, it could be possible to overheat your coils and get harsh, burned hits if you take puffs too long, and it's easier to get dry hits.
Do yourself a huge favor and get yourself a TC mod, brother! It works vastly better than watts mode, better flavor, longer atomizer lifespan, smoother feeling clouds, dry hits aren't as bad. It's really easy to set up, also. Just click a few buttons initially, setting 3 different parameters when you start, (TC wire type / mode, watts, and temperature) and after that it's just click and puff, consistency!
Yea, just about any idea for a ceramic atomizer for a tank that might seem feasible or hold novelty over my existing successful builds, I can't help but to try building it & filling it with oil. There's a few more builds I want to show here if I get around to it....glad to see you're enjoying the new big smok tank & RBA. When you get a little more time & experience gathered with it, it will be interesting to see you compare it to your cubis donut coils, the new and old ones.
As for the wismec RX2 mod, it is pretty nice, and if you are looking for a bigger mod to replace the vtwo mini, more for around the house maybe, and you don't mind a little heft and weight, the RX2 20 or 21700 could be good for you. (the color choices are a bit weird though, brown looked best to me, whatever) The eleaf invoke is a pretty nice mod also, I think you'll agree? But that one emphasizes small size & compactness, even though it still packs 2 18650s in just about the smallest case possible. Unless you're foolhardy to want to try out that quad rod
Good thought on the charger...my nitecore D2 charger i use for 18650s simply will not fit the 20700 cells. I also have a xtar VC2 which seems to allow the larger batteries to slide in there, but I haven't tried charging in there. I just charge thru the RX2 mod. I'm skeptical of in-mod 2 amp charging because it can get the CPU and cells pretty hot, but with AF, you can limit charging to 0.5, 1, 1.5 or 2 amps on mods that support it. I set to 1.5a (750 mah per cell) charge and it gets a bit hot, but not too much. (sometimes i cool the mod with a fan as I charge
Hmm, from their website, stiizy claims they have distillate? With 80%+ potency and those light hues, it looks like distillate to me. (co2 distillate?
Up north here lately, I've only been able to source "jetty extracts" for full-spectrum, runny CBD extracts, around 65% with 5 or 4:1 thc, about $50/g, pretty good.
The pop naturals were nice, and ahead of their day with some of their labeling / testing, but some of their co2's potency was not up to current standards. I had a few of their old syringes that were only about 55-60% cannabinoids, left a little extra residue on the LAYG donut.
Yea, you got busted on the reclaimed' QQ shot.
Can the source process iso? IDK what you mean, but I do believe you can get some use out of those old q-tip swabs, somehow...
Nope. Its empty. Just showing how low it can be vaped. I just took a tiny grinding wheel and took the lip off. It wouldn't go that low otherwise. But it's less than a 1/16" I removed. Definitely wouldnt drill more holes in the chimney. Its top air flow. Air path is where the holes aren't. TC. I have 2 dna200s and a dna133. Just worked so well on that little guy, or eleaf 20w. And it's small. I'll put it on temp control sometime. I had every intention when I got it. I just really didnt need to. Devine tribe...ofcourse! Ty! Did I answer everything? Vape donkey, your posts look amazing! I'm not as proficient using fc! Your coils look freaking awesome. I'm sure they work amazing! I have xwick already!Hi Tom, nice to have you with us, no worry on the drizzle love-fest on that other thread over there.

It was shooting either large hot bubbles or a steady, fine oily mist onto the mouthpiece and my teeth / lips. Trying any possible position on the air throttle, on unreasonably, high, hot temps would not stop the spraying. It wouldn't even make any vapor at all! Just oil spits. This was highly frustrating & humbling. 
I guess you might call that a "leak" but what I just forced into this tank I wouldn't call "normal operating parameters" - user error you might say. The foolish over-filling, and perhaps the sloppy jumble of wick in the bottom floor / middle of the RBA deck were the mistakes I made. And I was ready to try again and to avoid those mistakes after I got everything clean again....
Yes! in the range of 370-380F. However, with the added wad of wick on top, the airflow felt a bit restricted coming out of the RBA coil, which felt like it was dampening the cloud production somewhat. (15-20% less?) (can't blame them really)
Idk if I was 10 letters over or 1,000 so I just break it into 2 posts and carry on....
but should you build it? Even though this coil did produce some of the thickest, most satisfying vapor I ever huffed from a tank, this build did seem to be a bit sensitive & temperamental with the heat & spitting potential. The spitting was brought "under control" but never fully eliminated, which I did not like. The radiant heat generated from the ceramic rods, while not ruining the oil on my tank, was more harsh than my smaller builds. And compared to the very substantial clouds I was already enjoying from my quad donut (and also, spoiler: dual rod RBA!) it just seemed like this quad rod wasn't worth the trouble. ...this is one the best ideas I've come up with so far. For the next update?)
I didn't like that, and the flavor was only good (not great) so that led me to try the failed hole-adding experiment, which ruined this tank and made me go back to my cubis tanks. So it seems like the drizzle is a downsized, MTL version of the veco, that works a little better with low oil level? Cool you got some DNA mods as well, my bad to presume you didn't know about TC or want to run TC mode I guess your old eleaf mod in the pic threw me off. I also don't vape nic juice too. But I bet you'll find the vapor quality can be better & more consistent with TC over watts mode, especially if you like to take big, long drags & push your gear to the limit without combusting or dry hits. Vaping & making RTA coils is a hobby, sucking up alot of my free time, so I feel a weird sense of obligation to put it out here, in this obscure little corner of our inter-tubes, since I'm unaware of anyone else doing something like this?Man, I LOVE your posts! I diy a lot of stuff. Reason I have the xwick. I just don't think subΩ is necessary for concentrate. TC is a must for subΩ and concentrate tho.imo I use tc always with ejuice. Your correct about older DNA chips not working with higher Ω so I didn't try. My shitty state isn't medicalUgghh... I was trying to get that all into 1 post, but over 10,000 characters as usual.
Here's how much splash oil accumulated underneath my drip tip adapter week after 1 week of "normal use" . Much of that splashing is probably from my friends. I later put a small, mesh screen on the top of the chimney here, underneath my drip tip, and this took care of the splashing reaching your lips pretty much. Oil collects on the screen, but you can reclaim that oil and you must change the screen once in a while. Better than hitting your lip still.
The rest of the pics earlier above are 2-4 months ago, but this is my 3rd fillup on this coil once I finally got it right, just last week. The layer of old, darker oil on the bottom can clearly be seen distinct from the fresh, light oil on top
And then take a puff, mix' em up
And one more....
I know many of you may look at this and think that's pretty gross, I don't want that. I wouldn't blame you for thinking that. It was actually vaping very nice & fresh & tasty with the refill. (and not bad right before the re-fill, at low oil level too) Maybe 80% of the original freshness was restored?
So this ended up being a pretty fun, functional, powerful build for a tank....a wild ride...
Honestly, I wouldn't recommend it.
But hey, if you're really determined to build one of the most powerful, cloud-potential tank builds that can still make civilized, smooth vapor, as some sort of cackling, mad-vape RTA scientist
But really, quad rod ended up as a mere, potent novelty, to be enjoyed but phased out. When vaped down to empty again, I'm planning on switching this one to dual rods, to be more reasonable, as I've already proven the more modest, dual ceramic rod build on another X-baby RBA already.
So the low oil level in your pic is about where you stop puffing, or where it might start to dry puff. (not bad)
But if you didn't smooth out the edges on the big wicking holes like you did, you wouldn't be able to puff your tank to an oil level that low? (not as good
If that's the case, it seems the drizzle is about as good / bad on it's minimum, necessary oil fill level as is the vaporesso veco tank, to which it is very similar.
I put 1g of co2 oil on this veco, and enjoyed a few dozen pretty good, yet inconsistent clouds. But after this pic, the cloud production gradually declined, even though as much as maybe 400-500mg of oil was still stuck inbetween the glass and chimney?
That's good you didn't have to try that silly idea of drilling holes to see it was a bad idea like I did.
With the drizzle ccells @ 1.3Ω, I'm not sure if you can TC those on the older DNA mods? Many TC mods that are a couple years or older only TC coils up to 1.0Ω. The newer DNA 75/250 chips, and any mod that can run arcticfox can TC coils (of the right metal, like SS) up to 1.5Ω, and I've confirmed that with little tanks like the liberty V9.
True, you don't "need" TC for your drizzle tank; perhaps you're not as sensitive-throated as I am.
Thanks for the kind words too, comments like that keep me going here on FC. It's exhausting but also fulfilling in a weird sense after these long ass posts?
If you're handy with building coils, you got a sense of ohm's law, and you feel hungry for even moar good! out of your concentrate tanks, I'd encourage you to give a donut tank a try.
so conservative is a little more important, and I'm kinda over experimenting. The builds you make look amazing and I'm sure the work awesome. I have a veco. I didn't like the fact it needed refilled with a lot in it. And the space between the chimney and coil is large. Fine for eliquid. Not fine for concentrate.imo the drizzle has very little room between the coil and chimney. Its 18mm and 1.8ml veco is 22mm and 2ml. The drizzle is taller and skinnier. Better for concentrates, imo. Its basicially a Ccell cart, but a tank. Uses the same coil as Ccell carts, but replaceable and a very quality construction. I realize this thread is for advanced diy and coil builds. The drizzle is for anyone that wants a tank that will very effectively and easily vape concentrates at a thinner viscosity or thicker. It's an eliquid tank, so it works strait out the box with thinner viscosity, but uses their Ccell cart coil and can take very thick oil too. Ccell carts ALWAYS leaked with thinner viscosity. Drizzle it taf, and you can turn off the airflow almost completely. Only drawback is you can't buy just the tank. The supplied battery is to powerful for thick concentrate. Only learning curve is what power to use with the viscosity your using. It just works. Empty pic shown has about .1ml left. I'm usually refilling with a canna derived terp/bho mix and prefer to not have a lot on the tank when refilled. 5 pack of coils is $6 and change super easy and clean. Not much room between coil and chimney and it's all vaped out when the tank is empty.Tc could be used on a mod with a tcr function I believe, but I gave my rx200s to a friend. Basicially the driz is very efficient and effective and user friendly. Sorry for the long post about a non advanced tank.
