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

[JeremyR]

These are tedious builds for sure. As always there are different techniques that each of us find to work the best.

That's a nice looking build dice. Vapor production is definitely volcanic in the single coil.
Do you find the vertical coil improved the flavor of your juices?

Steppin it up with that dual coil man, nice dice. Good. Way to get the nr leads even. That's the dice coil. Snake eyes?

ROLMFAO!!!! Snake Eyes, 2 craps 2, double the bubble. come on in single the DP, double the field.

I like it. Snake Eyes.

Decided to try this on the Rocket rba, since I had one empty, so I twisted up a dually for the Rocket. Kind of murrfed up the coil a bit, bent my paper clip while wrapping the second eye, but slapped it in the rocket anyways, figured why not. Now the rocket being an ok cheap clone of the kayfun, it is not up to the performance of the Russian, so as stated before, I did some modifications to it to help improve its performance. Well, besides being a little tricky to wrap the double coil on a single strand, mounting it to the base was easier than the single vertical build, and wicking it was much easier too, imo. twisted up a piece of cotton and threaded it between the two coils, wrapping around back of the coil and into the side juice trenches. Came out to 1.4ohms with dual 6 wrap 28 Kanthal, vapped it.

OMG'd this cheap azz rocket is hitting better than my Russian is, which is my best build so far.. The duals get a better air flow, giving more vape, and bigger nic hit. Think I'm going to rotate the build on the Term-C 90 degrees, so that the cotton can encompass more of the coil. Will make re-wicking easier too.

I agree with you on more flavor on these vertical builds, it's even more noticeable on the dual set up. It's almost like you are drinking the juice out of a straw. I think that its because the vape is being forced up through the mouth piece when it's being vaporized. With the Snake Eyes you don't even need to draw on it to get a vape. Just tried it, and my mouth filled up with vape without drawing.

I am really excited about this dual vertical build. I'm only bummed that my other three rba's have at least a 1/2 tank full of juice, that's like 6 ml's of juice I have to vape before I can but the dual warp nacelles on, and then come down from the nic buzz. lol Fortunately, I only filled the Term-C half way up, excepting my Stainless tank section tomorrow from SVC so I only gave it a half tank for the test vape.

I didn't take any pic's of the Rockets dual set up, will do so when I rebuild the Russian though. It's same as the term's build just no non-resistant wire, which makes it an easer build and gets rid of the long leg that's in the single coil vertical build.

I am going to do this! WOW only one question- what size drill bit would that be? I have some 28awg Kanthal and want to try it on my rocket and the KFL ...getting excited

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.

Sax, I use a small blunt tip needle for a juice bottle or a large paper clip, that way I could get 12 warps using 28awg, and build a 1.2 ohm coil. You can use a 1/16" drill bit but would have higher ohms.

I'm switching over my rockets and the Russian to the "Snake Eyes" dual coil build. This makes the rocket way better. Using a large paper clip or blunt tip needle. two 6 wrap coils get 1.4 ohms. This eliminates the long leg on the single Vertical build and makes mounting easier IMO. Plus added performance and easier to wick properly. Least that's my take on it.

My only problem is that my tanks are all 1/2 full, so need to do some serious vapping before I can mount up my builds. lol. Once you have either the single or dual vertical builds set up and juiced up, make sure you crank it up to ~15 watts, this is where the vertical build shines, at around 10 watts, it's all good, but nothing special, cranked up, it's an eye opener.

 

[JeremyR]

Drain them.. I always dump my juice in a spare bottle I have. Rebuild and replace juice.

Yeah the dice coil is a sweet way to make the coil legs level. Great idea, any hotspot on that cross over leg? It is the middle of the wire.

I Will try it out soon.

 

[dice57]

No hot spot on the cross over leg that I saw on the test pulse, and since the wick butts up against it when wrapped, don't expect it to be a problem.

I thought of draining the tanks, but it's not like the builds that are in them are dogs or lacking, lmao, plus I am doing my coil wraps first, so it will be a quick swap out to upgrade. Need to grab a new cotton ball to, have use a whole cotton ball so far and I've only been building for a couple weeks. lmao. Fortunately I had the foresight to boil a good handful when I first started to use cotton.

Damn, but my cheap azz rocket with the dual nacelles is out performing my Russian. Have the Need for build!!! lmao

Finished the new dual coil vertical mount on the Terminator-C and the Russian rba's, with excellent results. After noticing the big improvement on the Rocket with the Snake Eyes build and how the cotton wick surrounded more of the coils, I decided to re-build the term-C. By rotating the positioning of the coils 90 degrees, and snaking the wick in between and around the coils, I've increased the surface area of wick to coil contact with great results IMHO. Both the Russian and the Term-C are pretty dead even with quality of vape and taste with this build. The Russian is much easier to set up, since you use all resistant wire, and when using the mounting holes, make's installing the duals, and adjusting the positioning a snap. Plus much easier to re-wick than the Term.

Below are a few picks to help illustrate what I am talking about with the term-c.

Pic of the Term-C with my new metal tank section, on the Provari, with Spot checking it out!

The following is a few pics of the Russian with the Snake Eyes build. Easier to install than the single coil vertical build and easier to wick, IMO.

This first pick is of the coil after wrapping around the paper clip shown. Damn Sampson is always sticking his nose in things. lol I haven't squeezed and torched the coil yet in the first pic.

To recap, I used 28 awg Kanthal in all my builds. Did a 6 wrap around a large paper clip for each coil. They all measured right at 1.3 ohms, give or take .02 ohms. To me, the effort to go dual on the vertical mount was not that much more effort than doing a single coil install. And the mounting of the Russian was actually easier to do, using the mounting holes instead of going around the screw heads. You can see the wires extending through the holes on the pic with the Russian on the ohm tester. Snipped the wires flush with the blocks after I had the coil positioned to my liking.

The Term-C is a little bit harder to wick. I swivel the coils out of the ceramic housing, while leaving the positive lead still attached and secured. I then slip the cotton between the two coils, and the wrap it around the outside in an S. Using both the negative leg and cotton wick, I gently coax the build into position. After screwing down the outside O-nut into install position and trimming the cotton ends, I then Screw the ceramic housing into the base. I leave the negative lead a little long and tuck it into the O-nut, so that when I need to re-wick the Term. will have something to hold on to.

When testing the build for ohms, I leave off the lower small O-ring that goes around the positive stem. Have found that by doing this, the stem doesn't loosen up when unscrewing the ceramic housing from the base, and having to retighten and align the stem up. Avoiding Frustration. lol

 

[JeremyR]

I'm Still running the same coil, I've been too busy with work.

I couldn't get that much cotton to work in the oddy last time I tried. The Russian must be a little different in that respect. I'm still having better luck with less is more.

 

[dice57]

I switched my Term-C to a hybrid coil, using SS mesh with a cotton core, horizontal mount. The dual vertical seemed a bit tight in this atty, and was really guncked up, so decided to change it up a bit. Pretty impressive once I got it to work. The SS mesh took about a tankful for the flavor to develop, but now is really tasty. Am hopeful that since the cotton is going down the middle of the SS mesh, that I can get some good mileage off it before having to replace the cotton. Damn, it's giving great vape though. Could be the licorice vape I just made too. It's just kewl that one can try different build styles on these rba's.

On the Russian and the Rockets, am sticking with the Snake eyes build, since they are so easy to mount up, and the performance just blows me away. Still have a single V on one rocket, it's working so well, and haven't had the time to re-build it. Plus the dual's seem to suck a battery dry much faster than the single, or my contact points need cleaning on the provari. Did order 4 18650's and the Tatroe Provari Ring and end cap, and a long drip tip. The P looks like a sonic screwdriver now or maybe the Empire state building. lmao

 

[bapgood]

This is from the Just Hemp Thread that has a lot of this style builds going on right now.

Been vaping this setup for a couple of days now and it is just awesome (after I get past the lag of the higher ohm 28g coil)


Rewicked and coiled.....28g...1.7ohm (too much IMO)...hemp fiber wick

A 5/64" drill bit from the little Dremel drill bit set work perfectly for the Russian. It slides in tight! and stops when it hits the size scribing, which kind of makes it nice.

Anyway I took pics this time....so you can grade me

 

[JeremyR]

That's a nice looking micro coil bapgood. That hemp looks very interesting. Much better than the twine stuff. More in line with the rayon I'm using but its hemp. Can't get much better than hemp really. At least in my book.

Isn't the draw really tight with the packed wick? I haven't had luck with a lot of wick. Much better for me with just the strands and the draw Is looser, so I get more Vapor with less effort. Maybe it's because I'm using 32 gauge. I need to get some more wire sizes. Either way it's a great vape. Vertical micro coils have really taken vaping to a new Level.

 

[bapgood]

The draw isn't affected because the id of the coil is the same size as the air hole in the Russian (2mm)

 

[JeremyR]

Mine is the same size as the air tube too. It may have been because i didn't have enough power. Just had to get a new 18650 and it has a lot more power than my old cheap ones. But it seems there is still some restriction in air flow in my oddity compared to horizontals with the extra air space. I like a really loose draw so that may be the difference too. Will try it again next time I have a chance.

 

[JeremyR]

Well with new imr's loaded up I'm getting great performance. I broke the 32g coil while rewicking so I pulled out an old Dual parallel 32 gauge 3/64 micro and turned it vertical. Its about 10 wraps x2 & 2.5 ohms; and was able to use more cotton this time. Its a pretty long coil, about 20 wraps of 32 total and its vaping great. The 3/64 coil is giving me better air flow.

I was in a hurry so no pics, but here's the coil as it was previously set up. I turned it vertical

bap so is your technique there to do a thinner wrap around the coil, then put the chamber on and add the packing top down?

I tried doing what I just described, and man it didn't work so well lol. I was in a rush and not being very careful though, so no conclusions drawn there.

Yeah....I have been a little hit and miss....but I have had the best luck using fluffed hemp and not really packing it....just kind of fitting a proper size pieces on the sides and then kind of working it all together to be about flush with the top of the coil.

 

[mikepetro]

I found that packing around the deck was temperamental. Too much and I got dry hits, not enough and it flooded. Part of the issue was the build changed as the hemp swelled from absorbing juice, and it was hard to predict the swell. Especially with the LONG raw fiber which tend to get knotted and bunched up.

I cut some fiber into 1/4" lengths and then soaked it in pure PG to let it expand. I then use tweezers to pack this cut and saturated fiber around the deck. I am getting much more consistent results this way.

I still use long dry fiber for a few wraps just around the coil itself.

Wrapped some raw fiber around the coil, threaded it through the negative lead loop to get a good wrap.

Filled up the cavity with my cut and saturated fiber. Used a syringe to pull out the excess PG when it got too messy. Was able to fill all the nooks and crannys very precisely.

 

[upsetter21]

WHoooassoso coool. Just when I was getting a little bored the envelope is pushed some more. Sorry for this useless post, but I'm so entertained I had to speak out. It's the cats that have me really laughing. If the cat is interested then this must be some good stuff. It would seem these vapes also help one grow long toe nails!

 

[dice57]

I initially posted this on the Aqua rba thread, but felt it should be posted here too. No pic's, but will snap some when I re-wick. I never think about pics when trying a new build on a new rba, to focused on the build. But this is a keeper.

After running 3 tanks through my first build on the Aqua, I decided to go Vertical. Used a 16 gauge blunt tip needle to wrap the coils, did a 8-9 wrap with 28 gauge Kanthal, then used a 18 gauge needle to mount the coils, since the 16 gauge wouldn't quite fit in the air holes to properly align the coil mounting. Used both the top and lower mounting positions to secure the leads. Distance of coil from deck was the thickness of the positive Isolater washer. Didn't want the coil to ground out, so mounted both coils the same distance from the deck. Wrapped the leads around the outside of the post, so that when tightening, they leads wouldn't slack up, and this also gave me the most room to wick.

Measured .61 ohms. With this vertical mount, the first thing I noticed upon pulsing the build was that both coils heated up exactly at the same time, same intensity, from the middle out. Which makes sense since each leg is now exactly the same distance from the post. I also did the pinch and torching of the coils before mounting to set them in place. I was starting to get excited.

Now the wicking. Used cotton balls from my pre-boiled stash, twisted up fairly tight. With one strand, went under the top leg and between the post and coil, through the middle and around the opposite coil, around the outside, and back to the apposing juice channel from the other side, so am using the kinny corner juice channels for one strand of cotton. Did the same thing with the other strand, doing an over and under weave where the 2 wick strands come in contact in the middle, and wrapping around the outside of the coil, to get the ends into the kinney corner juice channels. I left the tails long and doubled them back up, pushing the doubled wick into the juice channels, using the blunt nose needle to pack them in. I did this because on my previous build, noticed that if you barely cracked open the juice control, it tended to gurgle and flood, was to sensitive for good control, and was hopeful that this would help with extra wick in the channels.

Saturated wick, retucked the cotton into the juice track and around the coils and making sure the top holes of the coil weren't covered. Assembled and filled.

OMG. Now were cooking. Vape is even better. No gurgling at all, have the juice control opened 2 1/2 full turns, yes, 2 1/2 full 360 degree revolutions open. No flooding, no gurgling, no spitter, no splatter, just nice smooth slightly warm juicy clouds of tasty, tasty, vape. This puppy hits sooo smooooooooth. I have it kicked at 15 watts, 80% VG, 12 mg nic. Not even a hint of dry hits while chain vaping. After doing my first build, and thinking about it, thought the Aqua would be ideal for vertical duals. And it is. Give it a try, I'm glad I did, and I haven't even owned this puppy for 24 hrs yet.

I've been building vertical micro coils in my protank type/ Tatroe tank for a while and was wondering if I would be able to do something similar in my R91 that the mail man is going to deliver in about 10 min! Glad I found this thread!!! I figured it would work but nice to have confirmation on it and see how the wicks are done. On the kanger coils I just pack the cup loosely with cotton with the coil over the air hole. I'll probably try a horizontal micro with cotton for my first build and do a vertical at first rebuild so I can see the difference for myself and get used to the atty.

Thanks for all the info guys!
