A question... when you talk about kanthal 28g, 29g... For micro coils, you talk diameter of the kanthal? 0,28mm, 0,29mm.. ???
Which is it the best?
Thanks!!
Wire gauge has to do with the thickness and resistance. The lower the number gauge, the lower the resistance, and the more power that can flow through it for a given time. 28g is around 0.32mm. There is no "best", it just depends on what you're trying to accomplish. Generally speaking, lower resistance allows more power to be drawn from a battery. This allows control when using mechanical mods, which do not regulate the battery output.
Thanks!! I will use in provari. I want to make microcoils with 11 turns more or less. Can you recommend some link of kanthal please?
Thanks!!!
CRSS,
Does the swollen o ring return to be reusable again, or are they a done deal if they do swell, trash ?
Just good info in case this happens in the future...Anybody can list the juices they know that ruin this o ring..?
Thanks-
Yes after 2 days the swollen o-ring returns to correct size. I was swapping them every 2 days, running Grenada fluid. So i will say for sure, Grenada & Pluid will swell the "4c". But after 2 days sitting out in the air, the o-ring returned to its normal size.
Here is my normal size & swollen "4c" picture. When i figured out my air intake leak & crazy flooding.
Here is the ProTank coil seal I replaced my "4c" with, no more swelling!!

One of the main design ideas for micro coils is not having to go too low with resistance. Your Provari will apparently support sub-ohms, but there's really no need to do it. So, 30g will probably work well for your 10-11 wraps. It should give you around 1.2-1.5Ω
I checked the o-ring in my KFL and it is bigger than the new one but not by much. I will try out the new o-ring and see what happens. BTW, the protank seal you're talking about is the white silicone piece that comes with the replacement coil head?

You can go to temco and get a1 kanthal resistance wire. So far, I've only used 30ga but I have 28ga coming soon. If I remember correctly, I get about 1.7 ohms out of 8-9 wraps of 30ga kanthal on a 1/16 drill bit. I also have a provari.
Sure. Let me go thru this tank and I'll take a pic!
Actually found this pic on my phone.
have you tried the micro coil & cotton set-up? im sure this set-up is awesome but when you think of the coil coverage with a micro coil its amazing the difference. when you can get the coil to cover like 80 percent of the wick it has to produce better flavor and more vapor compared to maybe 30 percent in a standard coil.

you can use 30g but imo 28g works better. with the provari a resistance of approx. 1.4 works great so with a 1/16 drill bit and about 10 wraps or so you will have a great build. also the 28g holds better in its shape then 30g.
before people started using micro coils 28g wire was borderline for vv devices. the reason being was that it took to many standard wraps on a wick to get to a resistance that vv devices would handle. now with micro coils 28g is kind of being the standard. I don't use vv devices all that often because im used to vaping at wattages a little higher then 15 watts. did an experiment with the k-lite and some 27g wire with my provari v-2. on a 1/16 drill bit I did a 12 wrap micro coil, when I finished the coil I separated it in half then bent the coil parallel to each other. I now had two little coils side by side connected to each other. I then mounted it to the k-lite on a slight angle, this makes it a vertical coil compared to a horizontal coil. will post some pics. im amazed at the performance of such a thick wire on a vv device and the flavor is also amazing.
Vapdivrr, you can't just describe something beautiful and post a pic later lol. Can't wait to see it.
Would love to see a photo of this .... PLEASE???? (protank seal inside KFL)
I also had airhole leakage with my cotton wick setup. I moved the coil above the post screw level and my wick is slightly shorter than the setup I see in the phtos and also slightly to the side ... so far, so good.

1. KFL WASHED-UP AND WORKSPACE ARRANGED:
Attention: Don't ever forget the Multimeter. This is your 'most important' tool at rebuilding!
2. COILS PREPARED:
28AWG Kanthal, 13/14 wraps over toothpicks, 1.7/1.8Ω each. Resultant Resistance on Atty: 0.8/0.9Ω.
3. ONE COIL MOUNTED:
4. COIL SQUEEZED:
Note: The real benefits of a Micro-coils come out when they are tight-rolled, virtually in 'short'.
5. COIL POSITIONING:
Note that the 'spiral' of the coil is upwards with their tails at the bottom, the ones which'd get attached to the +/- posts. This is how I position all my coils on every Atty. Schematic below:
6. COIL HEAD UPWARDS:
7. SPACE BETWEEN THE COIL AND AIR-CHANNEL OF THE BASE:
Note the gap I left between the coil and the air-hole in the base. I typically maintain around 1mm space, which gives me the best VTF. Remember, the closer you are to the air-channel - higher the vapor production, the further you move away - more TH. It's pertinent to find a sweet spot here, which'd come by experience.
Caution: Do not touch the coil to the base, it'd result in a dead short. -DANGER
8. ONE COIL FIRED:
Firing at 1.8Ω, Multimeter checked!
9. SECOND COIL MOUNTED:
By far the most difficult part. Took me about 30 minutes It'd take time but you'd get it eventually. And once both successfully fire - it'd be worth the pain. Patience takes the best of it here!

16. SECOND WICK INSERTED:
17. WICKS TRIMMED:
18. WICK TAIL SIZE:
Trimmed each tail-end to 1cm.
19. WICK ENDS POSITIONED:
Note the wick-ends are just sitting/touching the bridge. I didn't make them longer to overtly lie there (as I'd do with Silica or EkoW) b'coz it'd've cramped up the space and constrained the juice flow. Remember, cotton swells like hell and remains so till there's juice in the chamber. Besides, they'd also sag and settle down a bit further than when we had initially placed them.
20. WICKS INSIDE THE CHAMBER:
Closed the chamber tube, tucked the wicks a bit towards the bottom.
21. WICKS TEST FIRED:
Dripped about 8-9 drops of juice and voilà!
BOTTOMLINE:
It's a cumbersome setup, took me over three hrs. Of course mainly b'coz it was my first attempt, which needed more deliberation. But, if you are into double the pleasure... everything doubled(!), a warm vape, an aromatic vape (yep, this gets to a room full of refreshing scents! Ah, some of our e-juices really smell wonderful, don't they?) and if you are contemplating reducing your nic content -- this is the way to go. Did I hear, "it hits like a freight train" somewhere?

that's a serious coil for sure. I do the same, im always doing different configurations of micros. good job qorax
