Spent tonight vaping on a T3'D and wrote a review of it. Classic little clearo...
I see this thread has been frequented for about two years. Did the original poster ever get a definitive answer to his question. I've noticed alot of ECF people will misdirect just about any question asked. They will throw everything in the book at you, except for what the amswers you were seeking.
I have a project in mind a simple 1.8 ohm - dual- horizontal coil for protank 3. I will be using these materials; 2.mm silica wick and 30ag kanthal round wire. What I want to know is, how many wraps will I need to make around each coil in order to achieve the target resistance. I'm going to be wrapping tight coils btw.
...but I'm typing this, to try and find out what works best when building an MC (microcoil) for the Protank.
Think the OP (a good friend of mine) got his (above) question answered but he had to start with what a m.c. "is", what it can do and how to get there. I think he may have experimented with verticals himself and posted impressions here. Also here are links to a PT dedicated thread on verticals that ran for over a year.
I introduced the tensioned microcoil on this thread and if you're after perfecting a Kanthal coil you came to the right place. Still enjoy some of my fav tobacco in a Protank Mega running straight wire 28AWG which is more than adequate for the airflow or a high contact area horizontal twisted center lead dual coil (@1.8mm Ø) like this one…
I can tell ya having built more than a few of these that throwing a lot of wire into a Protank is utterly useless unless you can make the wind efficient as well as powerful. Vapor dispersion (heat expansion) quickly shuts down output. There's not enough airflow to support airy builds. That's exactly what verticals are. When production is highly concentrated and excess heating to air limited the Protank can be a thoroughly enjoyable vape at around 17.5W, 1.5Ω>.
If you'd like to discover how to get that kind of density out of the small atomizer that a PT head is maxing out on limited airflow…you definitely landed on the right thread. And once you have those tools in your belt bro you can do it anywhere on anything.
Just post when you're ready. If somebody doesn't pick it up, I'll be glad to help.
Good luck D.
Hey D and thanks for the update on your sit. Same mess that got me into this pickle. LOL
The coil's the thing D. Hit that and 90% of the issues that arise are far easier to diagnose and correct.
Look, two things you should know. It's easy to build a microcoil (touching coil) because it's seconds to roll 'em out on a pin vise (see below). The symmetry matters to keep them from shorting. Wire most used is Kanthal, an aluminum alloy. When pulsed it builds an "alumina" layer on its surface (insulation, as in any electrical wire). Important here because where getting the wires to touch (short). If that happens and there's no surface insulation, the wire can go very hot. A lot hotter than the resistance would normally allow. That won't get you a good vape because what we want is vaporization, not excess heat vented to air. And that layer is ceramic which isolates the metal from your vape to boot. That's the sum up.
You'll need a pin vise (<10$), some common drill bits and a coil of wire to start (as pictured below). Unless you want or need to wind on 1/16" prolly going to need to shop for some 1.778mm drill blanks (bits) and sources are noted in earlier posts. That is the largest diameter you can get in the PT3 head and will get you the thickest wick possible as we're going to use the bit to stabilize the wind. The same method (of localizing exact diameters) that Kanger ultimately adopted in making the current Subtank OCC heads…was being done right here on this thread and the preceding Protank cotton thread since 2013. Organic cotton from CVS, etc. will do for starters on the wick.
Small investment and we can get you winding stuff in a few days (typical) that it used to take weeks and months to tweak. So search pin vise on this thread and you should turn up a bunch of links with the description you should look for (brass pin vise) or google it. As you get that in the work we can talk about steam-engine.com and how to select temperature and surface area goals for your tastes. You like it a bit on the warm side at 1.5 and a tensioned micro which you'll build will vape denser than a standard coil so cooler. That said, you'll probably be a bit better off at 29guage and 9-turns should keep you just under 1.6Ω, 10-turns just over 1.7 and you a happy camper.
Certainly possible to build verticals in a PT. I use them extensively in drippers but in a tank atty assembly with cotton external wicking they tend to concentrate juice at the bottom (or leak) and dry out and get hot at the top of the coil. There are ways to address that but we're talking an advanced build. First thing we all need to learn to nail on the head is…keep the coil from shorting. That means in terms of the wind and also training your muscles for that and the mechanics of installation. Process should probably be second nature to you within a couple of weeks. Didn't use to be that but let me tell you the instructions are here proven by hundreds of participants over two years as you'll see. And the idea behind the mechanics will certainly aid your understanding of how to duplicate the result everywhere.
Which of the airflow bases do you have? You eventually will need the v3 for the coil we'll be building.
Let me know when you're ready or post here on any question.
Good luck D.
I goggled "organic cotton at Walgreens" and it says you can. I would just make sure the label says 100% cotton. As for the wire question I use 30 gauge and love that but I have heard others use 29.Sorry to be so short with the reply in advance.
Can I purchase organic cotton at walgreens? The closest CVS here in northern nevada is a half hour away. I'd be spending more in gas than on the actual cotton lol. I do have a protank 3 btw. I think it's fake though. The scratch off code returned the result that my authentification # has already been checked over 250 times previously. I guess that's not too important, as I can just break down these 2 ohm coils that came with the tank and try my best to build them in a better fashion.
I'm sorry but your attaches images will not load for me. I think I may have to check this on my laptop instead of my ancient iphone 4.
I still have to order the wire...would you suggest 30awg kanthal for a 1.8 ohm coil?
p.s. I guess this reply wasn't so short afterall.

Nor can we discern that from this interview with Dr. Farsalinos. It is unclear to me how any metal off-gassing could bypass a uniform A2O3 deposition of Kanthal. That would infer that the alumina is being compromised at extremely low temp's (contrary to its specs). Considering that in normal operation (no hot spots, or exposed wire) of a properly oxidized KA1 wind vaporization should stabilize at/below transition temperature as long as the wind is thermally stable and there is adequate transfer to product flow.
A thermally stable wind is what would then be indicated? No?
Kanthal was designed as a heating element. Its oxidation ensures its durability and resistance to corrosion. As acknowledged by Dr. Fasalinos ceramic insulates (isolates) the base metal/s deterring metallic oxidation of the vaped product. Such a wire/wind not properly oxidized would then exhibit all the primary metal exposure as the alternatives, to both product and the airstream.
So shouldn't we be pulse-annealing all our Kanthal winds in lieu of torching? To properly optimize the winds thermal effectiveness, stability and for the presumptive safety reasons concerning metallic exposure.
Instead it's inferred we shouldn't be torching our coils at all without an alternative. For Kanthal, relegating it to the same potentials of metallic exposure as every other wire variant. I'm not dispensing with the utility of the latter merely pointing out the difference in potentials for KA1's best use.
My reasoning then would be that Kanthal was not used or considered. And not cited per any summaries I've seen yet. Then you're right we don't know what metals are being referred to. And if the coil is what remains "one of the big unknowns" why not address that first and foremost.
I agree with you AT we need to oxidize KA1 and a simple process we all need.
Good luck.
Sorry about that. We all get a dud from time to time. Aftermarket head assemblies should be ok. If the threading is bad it may leak worse than the factory. All 510's leak btw. We try to make an efficient coil so that they actually vaporize. Novel idea. Best chance to avert over-saturation (insufficient power to wick).
Not sure if you were referring to my image/s.
Glad channel was able to pick up. Holler if you need us.
Good luck!
p.s. And post picks if you can. Don't be bashful (I use an iPhone 4S). I know, I know, retro.

Very informative thread thanks for the tips from everyone.
I was using mpt2's exclusively for about a year now and my usual build was a 6 wrap tmc 5/64 bit 32 kanthal twisted usually came to 1.6 ohms. Since I have got the stm have been spoiled by airflow and mpt wasn't cutting it anymore so I modded it as follows.
Coil chimney stem drilled out with 7/64 bit.
Coil center pin drilled with 5/64 (most tedious step)
Coil base drilled where the flange and threads meet with 1/16. 4 holes spaced as evenly as possible.
Also the mpt bottom base drilled out the small airflow holes with 5/64
Build I use for this setup is 5 spaced wraps of 32 twisted kanthal around 1/16 bit wicked with rayon snipped very close to juice channels. Usually comes to 1.2 ohms. I find the spaced wraps in a set up like this helps to alleviate gunking.
It works very well vaping at 12 watts. Getting a nice steady lung inhale with no dry hits and decent vaper.
I know this is a micro coil thread aand I appologize that the build is spaced but it has just been working so well for me that I wanted to share.
ETA heh I know the mpt doesnt hold much juice but I used to vape 18 nic and now do 3 on the stm and find about 9 on the mpt is the sweet spot. Vaping higher nic on the mpt I dont vape as much and the tank lasts a little while, probably longer than a tank on the stm. I love the mpt I will definitely be using it until its worn right out which will be quite a while with the right up keep because they are a quality built tank.
Cheers
lol come on now be fair the mpt is great to use for higher nics that would otherwise make me gag if I tried to deep lung inhale no? I find it a great alternative and the build I mentioned works very well.Welcome. No worries. This is a smorgasbord and we will get to the great vape eventually. Let us know when you're ready to ditch the appetizers!
Good luck.

Hey MacTechVpr!
I'm on MVS right now looking at a subtank nano...
Should I buy it? It says minimum draw required to fire the coils is 15W. I like the battery life I get with my current set-up.
How much of a blow will my battery life take if I start sub-ohming?
