Vcore - vertical micro coil in oddy/kayfun/Russian/Ithaca/ect.

[JeremyR]

A few of us have been running these for a little while with good results. Me, Cyrus, and dice. discussion on This build started here - http://www.e-cigarette-forum.com/fo...63-check-out-my-nano-dragon-coil-build-3.html

I started this thread specifically for the vertical build variant of the nano dragon. My modification that improved the vertical build is the cotton core. a vertical micro coil with a cotton core in addition to wicks.

We are wicking the outside of a vertical micro coil and drawing through the coil itself. This is similar to how a carto is set up. The flavor, th, nic, and vapor is increased over our horizontal builds in these. They are trickier to set up but worth the effort if you can get it down. I always thought cartomizers produced a more true flavor. This build has delivered me the truest flavor out of any build I have done.

You need a lot of air flow for this to work well. A pretty loose draw, like a smoketech carto.

Pictures show a 1/16 vertical micro coil of 32g at 3 ohms. In the oddity, oddy clone.

Mounting

Coil after releasing fire button.

If you've ever taken apart a carto you'll find a Wrap of cotton on the coil. I had been just doing the wicks but I Have found the wrap takes it to the next level. Pull it apart evenly. I used a needle to help. Make a Flat piece of cotton. Make it paper thin and fold it over. The piece pictured is very thin. One layer of a cotton round cut to size would probably work better, I will use that next time.

I have a small pair of scissors so I was able to cut it at the inside edge of the ceramic, and make a small over lap with a needled.

Wrapped

I used a rayon wick here, you certainly could use cotton. I trim them to just fit into the ring and tuck them in. Fluff the wick up with safety pin if they get pulled tight up top.

Wicks

Soaked

I put this together before work and left with no back up. I Let it sit upside down for five and soak for another 10-15 Min and was blown away - best quality vape I've had.

Try this in anything you can. The wicking is the hardest part. Well.. and getting enough air flow. I had already modded my oddity and pv So it wasn't an issue.

Props to Iteo and superxdrifter & the micro coilers.

 

[JeremyR]

This was my first build on the vertical coil and it worked great but the wrap was a little touchy to replicate for proper contact. The cotton core wrap takes away that issue.

Looks awesome. Thx for the info. I will try this on the Penelope.

 

[JeremyR]

Your welcome sad, if you get it on your first try.. prepare to fly.

Looks like I'll have to drop my nic down from 12mg. I'm getting nic'd out. Been on 12 mg for 9mnths could chain it on horizontal wicked micros. With the new Vcore setup I was buzzed after 3-5 draws. Had to put it down!

I have an Oddity just sitting here but I probably will try this on a KFL, at least the first time, been thinking about something like this for awhile and that PID build got me going even more as I use to refer to the cotton on a carto's coil as a diaper. I have subscribed

I'm waiting on a juice order of 200mls and I'm vaping some other juice that I originally got for my Wife. But she's not using it. It's not the best flavor, but it's doable. I really can't taste it due to vapors tongue, but the TH is there. I'm sure I'll nail the build on the first try...just depends on the ohms that turn out on the build. Good thing I have VV/VW.

Also with the Penelope I use the MRKrinkle method. But I only use half MrKrinkle, meaning that only one side of the Penelope has the wick going down the channel. And since the Oddy is different than Penelope. The Penelope has one channel ceramic and one channel all metal, instead of two ceramic channels like the Oddy. The wick goes down the metal side with the wire underneath to keep a good connection. This is how I do regular builds as well and it wicks just a well using silica compared to using cotton. I was using cotton before I figured out this build and went back to silica. With two silica wicks going down both channels it doesn't wick as well, no matter how much you open the juice control.

 

[JeremyR]

When I have a slightly slow wicking on the oddity, or just want more than it will give. I crack open the top cap and I get full saturation. You can only crack it open when its pressure is stabilized and vaping well just a little on the dry side. I've left the top cap open for the rest of the tank and over night. If done at the right time I get no leaks or gurgling.. But much better flavor and vapor.

Waiting to see how others get this done in their rba. Pictures and results!

Jeremy,

So if I understand you correctly, you first wrapped the coil with cotton, the added another wick across the top using rayon, to wick from the tank to the cotton wrapped coil. Is that correct?

Also it appears that the top of the coil is even with the grooved out ceramic slots, so that the top lead leg would be even and resting on the ceramic groove. So how far is the bottom of the coil from the top of the air intake hole in the base? Know on the Kayfun style rba, it needs to be ~1mm or you get a harsh throat hit, or about half the thickness of the screw head from the air intake.

Also have you tried a smaller diameter than 1/16"? Found when using a small blunt nose needle tip from a juice bottle, which is less than 1/16", for my coil wrap on the Russian, the vape shoots through the center like Old Faithfull. Or did you find 1/16" to be optimal for this rba?

I know, we could call it The Geyser build!! Too bad steam turbine has been taken already. lol.

Also did you drill out the air intake holes on the stem of your atty to improve air flow? Feel that the air flow is to tight on the Term-C to provide a better vape while at 15 watts. That's the one point where the Russian has the Term beat. It gives an easier draw with a fuller thicker vape., so far.

Will post pics on my Vertical build of the Russian tomorrow.

I think I am going to wait for the pic on this (kayfun lite and rocket) over here. I guess I need to get some different cotton as well as the cotton balls I got at CVS is not doing it for me I see all the great results you guys are getting and I WANT SOME TOO! )

 

[JeremyR]

Yes a flat paper towel thin type Cotton around the coil. Exact width of coil. Then I had two pieces I made of wick and ran one on each side of coil. Heck silica may even work with the cotton core in there. haven't tried it just yet. I like the rayon better, or cotton if that's what you got.

This is 32 gauge coil after wrapped, later heated and compressed into micro coil. (Can't wait to get 28 & 30g wire)

The top coil leg I tried to make flush with top of the ceramic, the bottom leg is resting on ceramic. I have neg on top pos on bottom. The twists are inside the ceramic... you could easily run the pos & neg the other way on the term to take advantage of The Ground. There is plenty of clearence to any ground in mouth piece. And the 28 is study enough to hold its position.

There is a large distance to the air hole, same as with regular hcoil, since bottom of the vcoil is at the same level, the bottom of wick channel. I have run them down deeper with a nano coil. At the time I wasn't able to keep enough juice to support the nano. But now with the cotton core I think it will work! I only tried nano once so far.


Nano Vcore the end if the bottom twist was the level of the Channel. That one was pretty close to intake.

 

[JeremyR]

Cotton balls will work. The cotton core is made from cotton ball on the pics above. Cotton rounds are the Makeup pad looking things for $1 . If you want rayon, Pick up a cheap bottle of some vitamin / supplement that has a Neutral smell, most likely you'll score some rayon batting in the bottle.

 

[dice57]

Thanks, Jeremy, that's what I thought. I am really liking 28awg Kanthal, able to wrap some long coils at 1.1 ohms which are an advantage for this build imo. longer coil gives more area to wrap around. matched with the 28 gauge nickel makes it easy to make a great connection for this style of coil buid.

I am really liking using cotton balls, I just boil off a handful at a time so that I have a good stash to use at all times, and it wicks like crazy. I have some decent pics of this over on the dragon build thread, for those of you that have a kayfun style rba. will update here after work Sunday.

When I do the Vertical on the Term-C I will be using all cotton wicking and will update everyone here on my findings and do a photo layout also.

I have this build on the Russian and 2 Rocket rba's and all three are vape monsters for sure. I modified the rockets by drilling out the air intake and adjust screw hole's because I found them to be lacking in performance compared to the Russian, after i noticed that the Russian's holes were bigger. After doing so, the Rockets performed much more to my liking. Now they are almost vapping as good as the Russian.

Just marking my spot, bbl!

 

[Sad Society]

With my experience with cotton. The cotton doesn't last very long. Also I have different gauges of wire, 28, 30, 32, and 32 works best for me. The thicker wires take longer to heat up. Which is kinda of pain. It might me different if your using a mech mod. But I couldn't tell you since I only use VV/VW. I'm not into sub ohm. I use to build 1.2 ohms on my first Lavatube due to it's limitations. But now 2.0 ohm builds work well on the Vamo. The TH and flavor is there. I'm not concerned about health scares involving silica. It's just a matter of knowing how to get it to wick right.

 

[JD1]

....... After doing so, the Rockets performed much more to my liking. Now they are almost vapping as good as the Russian.

Does anyone know if there's a drip tip adapter for the rocket?

I have tried this build on my kay-lite. at first it did work fantastic but eventually leveled out slightly. I tried re doing the wicking several different ways and just couldn't get as consistant results then a regular horizontal micro. maybe there is another trick that im missing. basically I wrapped the whole coil with the cotton and back down to the deck. I even tried adding additional bits of cotton around. maybe the cotton I added around the coil was to thick. although I managed to feel the vape difference between the vert & horizontal I don't believe the added effort is worth the time, especially in my set-up of lower resistance because the cotton needs to be changed every other day. anyways will still experiment more because I do like vertical coils. the best set-up I have done in the k-lite is a double vertical coil (all one coil just doubled over) I regular wick this but center it up on the airhole, this provides air flow coming up between the coils and lets you wick it traditionally.

 

[JeremyR]

I noticed those issues with getting wicking right too. That's where the cotton core steps in and Eliminates the wick issues and adds consistancy. I did go back to horizontal micro coil for 3-4 days till it gunked up. Just to compare. But when i tried the vertical with the cotton core wrap it absolutely blew it out of the water.

That's what the cotton core did for me. A lot easier to set up and replicate, as well as giving the best vape quality I have ever experienced.

The cotton core wrap is much much better than the wrap around wick I posted in post 2. Post 2 picture was my first try on the vertical. Does not give best results in my experience.

You need a lot of air flow for this set up to work best. Adjustable air control or modding to get it loose. Or loosening atty out of your 510 some to get more air. I had already modded the oddity and my pv before hand.

 

[dice57]

The following is the photo's of the build I used on the Rocket rba, kayfun clone, cheap clone. lmao. I used 28awg Kanthal, 12 wraps around the tip of a blunt nose needle tip from a juice bottle, build at 1.1 ohms. When fired at ~15 watts, I get awesome results. I tried to show the cotton amounts and lengths. Getting it just right is a matter of trial and error. I have the Russian and 2 Rockets set up with this build and all 3 perform flawlessly. Great wicking, can chain vape a whole tank with no dry hits. I can use the same wick for 5 days without need of fresh cotton. I also have started to clean out the wicking channels with a Q-tip and some rubbing alcohol, to insure my heavy VG juice does not clog them, when I change out the cotton.

Have found that the legs of the cotton need to be just touching the end of the juice deck so when you put on the containment ring it screws on nice and easy, with no need to stuff the cotton up and in. Again, this is a matter of trial and error, to much cotton in the juice deck and it can flood or block the juice channels. But now I can re-wick these rba's and get tank after tank of great vape consistently.

Also, height of the coil above the air intake is critical. To high and you'll get a nasty throat hit, almost as bad as a dry hit. I have mine about 1/2 the hieght of the mounting screw from the air intake. This came to my attention after a new build on the Russian, was working great but seemed to lean towards dry hits, so when I went to try a new wick wrap, noticed how high the coil was, so I simply put my needle back through the coil, so that I could align it, and pushed the coil closer to the air intake. Pulsed the coil to reset the new position, re-wick and working like a charm.

Hey Jeremy, How about M.E.W. for this build? Micro External Wicking. The kitty connection. lmao.

Did a dual vertical build on the Terminator-C today. Calling it the Snake in the grass. Used 28awg Kanthal, doing two separate coils on the same wire each with 6 wraps each. Measured 1.4 ohms vapping at 15.36 watts. This was my first attempt at this build, using Jeremy's idea of the cotton core wrap but around two coils vertical mounted. It is hitting really well, up to the Russians performance. Just need to play with my cotton densities and the non resistant wire connection. But quite pleased with the initial results. I've also drilled to 2 air holes on the stem out to 1/16", so that I could get better air draw through the Term-C. Glad I did, much better draw for my taste when vapping at 15 watts.

I used one rolled stand of cotton, and snaked it between the coils S style. so the cotton wick goes around on side of the coil and between the 2 coils, then around the other side of the coil.

I'm leaving the ground wire a little bit long after wicking the coil, and tuck it into the O-nut once tight. This way I can easily re-wick the term.-C by lifting the coils to the side, slide in the new twisted wick between the 2 coils, pull the ground wire down into the track, twisting and placing the cotton wick into the tracks and then screwing down the O-nut then install the ceramic housing into the base. Kind of like popping the hood. lol.

I have the juice control wide open, as far as it will go, with no leaks or gurgling. Just a nice good vape. At first I had it only a partial twist open, then had to open it more so that it could wick more at the high wattage, finally opened it fully, been like that for an hour with no issues.
