been vaping the vertical micro coil in my pt2 for 2 weeks now. my only complaint is its not wicking fast enough for me but no gurgling or leaks im using cotton yarn for the wick. ive tried just cotton neither seems to wick fast enough. the only way i can get it to wick is to unscrew the top and watch for air bubbles to rise up through the juice and then its ready for 6-8 hits then i have to unscrew top again to get it to wick. ive tried less cotton, no change and more cotton just made it to hard to pull air through so i will have to keep playing with the setup till i get it to work by itself.

Probably need a little less cotton primarily right in the wick holes. Age, how dense depends greatly on juice viscosity , and how loose it restrictive the draw is.

i can try less but im barely using any. i split a piece of cotton yarn in half so i end up using a whole piece of yarn it has 4 strands i can split it in half again and give it a try but then it will probably leak. thanks for the thought though i'll at least try it cause other than it not wicking fast enough when it does have juice its dang good way better than stock coils

This is how I always run my protank with any build. I leave it unscrewed once the pressures are stabilized. For me its the only way it doesn't flood but wicks fast enough. Just leave it unscrewed like that, you now are using it in juice control mode. Only time you have to tighten it is if you pocket it and walk around.

i'll have to try it. right now i just unscrew every 6-8 hits and its been working great this way but i was thinking because i vape at 15 watts and 6 volts that that is why it cant wick fast enough. im sure if i turned down the power it would probably be just fine i mean its a pro tank doing massive clouds of killer vapor easily triple stock output what do i expect lol. i got another 1.1 ohm vertical that im going to be firing with a dna30d soon my boards are in the mail. im going to be bumping up the watts into the 20's doubt i'll ever need 30 watts but it will have a little more headroom with the 30 over the dna20. pretty excited to get started on my 30 build but finding the right enclosure is pretty difficult. i want it bigger than the vaporshark but not as big as the duke so i'll keep looking till i decide which one i want to use.

I tried this last night. I'm sure they'll get better with practice, it took a little longer than a horizontal coil for me. I used cotton yarn and apparently put too much in at first. After removing some it worked fine. Definitely no gurgle or leaks.

Decided to tackle my first vertical. WOW is all I can say. I did an 11 wrap of 30ga kanth on a hypo needle that just fits snugly through the air hole tip. Fired and pressed. I then ran a 1/4" piece of xc116 nextel sleeve up the positive wire and over the coil. Solves the problem with the neg wire shorting. I then filled in lightly with cotton. Specs out @ 1.8 ohm on MPV2 and hits like a monster. And the taste is unreal. Setup in a Mini Pro Tank 2.

The vert I did above was on the replacement Coil/Wick for the Kanger Pro Tanks. Many sites will tell you that the Kanger MT3 has a coil that Kanger doesn't make a replacement coil for and that you have to buy an adapter for use with the newer replacement Coil/wick for the Kanger MT3S. I just installed single vertical coils into the old MT3 wicks with great success. I fell for the upgrades and never liked the fact that the thread match on the adapters were horrible. This makes all those MT3 I had laying around very much usable again. One thing I've noticed is that before the vertical upgrade, the OEM coils didn't last very long and clogged quickly. They also would burn the liquid intensely if you didn't notice the liquid running out.
These new verticals are a whole different story. No more burning/caking as the coils remain unusually clean. Plus the cotton/nextel wicks remain clean as well. I've gotten a week so far on the first vert mod and all is working great. Whereas I would originally be replacing the OEM coil by now because of failing taste and vapor production..

Interesting build adaption with the Nextel sleeve Syfi.

You have to be very gentle with that small of an amount. It tends to want to just separate from it's woven state. I get it to stay together long enough to get it in place by wetting it slightly with juice and letting it sit to stiffen. Once positioned I then stuff organic cotton around it so that the nextel forms a barrier against the coil. I tweezer some of the cotton out to the slots, check that the coil is aligned with the air hole and attach the stem back on. Fill er up, let sit 5 min., and vape away. So far no juice gurgles or bypass. And I've refilled the original build over 2 dozen times so far and she still hits like new.

The nextel wick is amazing. I sleeve it over SS cable wrapped with 3 wraps of flat 28ga kanth on my RSST. Goin on 6 weeks for that build and still clean and strong.

Has anyone tried this in a mini protank 3? I rebuilt the dual coils with some micros and they worked fine. But and for me this is a big but, they will be a real PITA come time to swap out wicks when changing juices. In my mini PT2 I can swap the wicks on that micro coil I built in no time.

I did a vertical coil in the MPT3 tonight and it gurgles pretty badly. I did not do a micro. The coils weren't touching and I did not torch it other than to anneal it before wrapping. The challenge with this atomizer head seems to be getting the coil long enough in the longer dual coil head while hitting my target ohm range and I was limited by the wire available to me. I used 30 guage (my lowest guage) and 14 wraps got me to 2.5 ohms. I had to stretch the vertical coil justy a bit to make it tall enough though once I got it in there. It seems my mini protanks do best for me around 2 - 2.5 ohms. I ordered some 28 guage to try agian with a tight micro coil. I packed the cotton pretty tight. It did improve when I switched the 50/50 out for some 20/80 juice but it still gurgles a bit much for me.

I think I'm close. Hopefully the 28 guage will get me there. Any advice regarding coil diameter with the 28 guage? Any other advice?

I rebuilt the vertical coil for the Mini Pro tank 3 and it's not gurgling anymore. I used a larger paperclip the first time and something just a touch larger this time. I picked up a mini torch today so I could get a nice tight coil. I used the same 30 guage I tried with yesterday. It was quite short and I expected a fail but it is working beautifully with a high vg juice. I will try some 50/50 in it tomorrow.

I've had good success with the coil below the wick openings on the single coil heads. Cool to see it can work in the larger dual coil heads. I can see where having more total cotton inside the head that is allowed by use of the larger head could be beneficial to regulating juice saturation.

Hey, need pics!

Thanks for the hemp Bsd, my trials with it have been complete. And I have a wick shoot out going right now. I am finding one certain type that I used before to be superior. Currently I just put in a hybrid wick with it including the hemp as the core wrap. Will see how it performs.

Tdc - if you get pics on next build please copy post to both threads, thanks.

I let the vertical coil in the MPT3 sit overnight. I thought I may get a gurgle first thing this morning but no. It's hitting smooth.

Here are some photos from the build that FAILED. I will take and uplod more photos this morning of the build that is working. I will also unwick the coil to get some photos, add new wicking and try a 50/50 juice.

Ok, the failed vertical coild build.

Well I'm running out of time and won't be able to unwick the atty head and take pics of the coil but I do have some pics for you.

Here is a PT2 atomizer head beside a PT3 atomizer head. Notice the area that houses the wick is much taller. I thought for sure the atomizer would leak and gurgle but it did not. I'll explain why I THINK it's not leaking further down.

MPT2vsMPT3ATTY.jpg

Here is the atomizer head with chimney off and the top wick that portion that I used to fill the gap between the wick and the chimney folded down. I thought it might help to see how far up into the wick slots the top wick rests.

MPT3VERTATTYSIDEMINUSCHIMNEY.jpg

Take a close look at this side view. I didn't leave the top wick laying flat in the channels designed for it to rest in. Rather I folded them up just a bit into the open air gap between the wick/coil and the chimney. I have the silicone ring off in this pic but even when it is on there is a large gap. The remaining gap you see in this pic is covered by the silicone chimney ring when it is on the atomizer head.

MPT3VERTATTYSIDE.jpg

Here is the atomizer head side view with the top wick removed.
