I started using heads from some cheap smok clearos that I had, the slot in them allow a 2mm bit all the way to the bottom. I set them up with a twisted pair of 32ag, tension wound and terminated, cotton wicked. Never thought I'd see this kind of performance out of a ProTank, it's outstanding! I dare say it rivals some of the single coil rba's.

Aro style coils? Those are more expensive than pt2 coils. That being said, 1 5 pack should last me ages.

Definitely interested in ordering some of those coils. I've noticed that the 5/64 actually created substantially better vapor/flavor (no surprise -- more wicking)... On my hand winds. But that was when it wasn't shorting, lol. This is far more consistent/repeatable and I've not had ANY connection issues since working the 1/16th drill bit tmc.

Humm.. I don't think there Aro style, they came out of these Smok type clearos > RBC Glossy Clearomizers

They use the same replacement coil from the looks of it. I'll need to look for some better prices... And check if my 5/64 " drill bit will fit in my two aros coils. That would be fantastic. Been having leaking issues with both my aros that I've not experienced with the pt2 heads. (Maybe it's just the Aro and not the coil housing itself).

Kudos to metalhed73 and Mac for their experimental work here. The properly-tensioned micro coil works a world of wonder, especially in the KPT3.

Just introduced my GF to her very first microcoil. Built to 1.9 Ohms, and wicked with OC. I set it for 9.5W, handed it to her, and the look on her face after the first vape was priceless. Wish I had a pic.

As a little background, she is vaping Max-VG liquid, which as we all know gunks coils overnight. When she came home from work, she was complaining about the little wisps of vapor she was getting. I just put a new stock Kanger head in LAST NIGHT! 24 hours and it is caked with burnt residue. Yechhhh. So I figured I would go the rebuild-route.

That one single tensioned micro in the KPT3 head puts out twice the vapor and 50% more flavor than the stock DC heads. I used the chuck of a Dremel 4000 to anchor the wire and 1/16" bit. Went for an 9/8 wrap w/ 30ga, and landed at 1.9, though I was shooting for 1.7 really. Tensioned legs, and then terminated the leads by twisting and the results were flawless. No hangers. Resistance is steady.

Think I'll use some 28ga next time, shoot for 1.2, and see if she likes the added heat and vapor production. Thanks for all the priceless input and research you've posted! Cheers!

Two things you should definitely try…cotton and Nextel XC-132 in a ProTank.

I tried the cotton from q-tips. It felt awkward trying to figure out how much to use. I've read about using the Peaches and Cream yarn. It's cotton, and already shaped into a specific, consistent diameter. I think it would fit the criteria for Occam's Razor.

Unfortunately, I won't be able to get some for 3 weeks. Not too many shopping opportunities here in the desert. :)

You lucky, more wick is better. :D Congrats.

Good luck.

An option I tried briefly before abandoning larger coils and limiting my remarks to narrow slot diameters...

Amazon.com: Cotton Square Braid Candle Wick - #1/0

I abandoned cotton on the ProTank as too much work for most of us to rewick maybe multiple devices every couple'a three days. Also the benefits of terminating at the bottom of the slot in controlling flooding is very important. Now with tension and the micro it's huge. I can't see the flavor advantage of giving that up for a slightly larger wick and cotton. However, I use cotton almost everywhere else. There is something to be said about a standard wick density. The results are far more predictable. And sometimes getting the density right for rolled cotton or cotton balls ain't gonna happen.

Just sayin'.

Good luck.

:)

W+C you're alright with that build. The tightest set I've achieved on that wind is...30AWG, 9/8 1.58mm i.d., t.m.c. =1.83 Ω √ as per resistance tables I post from time to time on Protank MicroCoil Discussion!!: Protank Contact (micro) Coil Resistance Tables. This thread continues the theme here with more advanced building methods and approaches to targeting temperature. I'm sure you will appreciate the data and enjoy the results.

Good luck and thanks for the ack.

I don't teach or promote hand winding P9. Been trying to steer folks away from it to a more proper and efficient electrical build since I started posting. I realize not every one has the time to read both the threads I've been posting on. I'm not lyin'. For reals.

It's awesome you got the pin vise. So I hate to say this dude…the wick goes inside the coil. Not over the bit. You feed it into the coil only after it's installed in the assembly, fired and glows like a microcoil. Then it's rigid, bonded and tight is it can get and you can proceed to wick it.


296858d1390192718-protank-microcoil-discussion-img_0675a.jpg



It's a delicate feed inside of 1/16" and that's what I keep telling everybody. A lot easier into 1.7mm or .07" (1.788mm) which I prefer, a slight tad loose and it feeds right in. A blind person like me can do it without magnification and it takes seconds. What you describe is WAY TOO MUCH WORK and does not produce an efficient coil. There is practically no chance of any adhesion of the coil doing it that way and the molecular bonding potential of Kanthal is lost with a hand wind.

So, build that perfect coil and try starting at 1.8mm to wick it and you will have a great vape tonight. I promise.

But don't forget to pulse it and confirm you have a properly flowing microcoil before you do! You can't recover from that. It pretty much is a standard coil from there on. You burned it in. To make a proper molecularly bonded microcoil requires that the Kanthal be virgin metal at the first oxidation. Anything after that is forming not adhesion and wil not result in the same efficiency.

There's you're answer…the wick goes in the coil, not on the bit. Do the build; then, wick it.

It's tempting to consider starting all over on a new thread to show what the development of a proper coil is but it would be a major project for this user. Volunteers for the editing staff welcome though. Don't all speak up at the same time (bring hi-res cam).

Good luck.

:)

Mac, a couple of questions please...

Would you recommend the 1.78 or the 1.8mm bit for coiling and easy wicking?
What's the purpose of the two extra pieces of wick laying in the well in your photo, are they replacing the 'flavor' wick on top of the coil?
After coil/wick preparation what do you do about the silicone cup/grommet that goes on the chimney? (I don't know whether to replace as is, replace upside down, or remove it)

Thanks for your help!

Either 1.788 (.07", 3/43") or 1.8mm is great. 1.8 is very near the width of the slot you may have to rasp some assemblies for it to fit neatly. The more wick the better as long as you can stabilize it at the lowest point in the slot (to make things taught and limit resistance). Nextel will insert easily into either. And either Eko or silica with the "cellophane" method I describe on the Microcoil thread (the link's on my blog).

This way (, or that way), does matter on the top cup silicone. Leave it as it's installed from the factory. It's not a decoration. They don't waste money for nothin'. It's a buttress for the chimney stack coming down and provides stability for the orientation of the assembly. But more important it covers up the top of the slot to inhibit excessive juice from entering the cup. Take it out and you may risk flooding and failure of the coil and connection. Silly assumptions on this forum…and all too often repeated.

Unless you use something like cotton and can really fluff up the exits to the slot, you need a top wick. Two 1mm sections, or 1x1.5, for example if you use silica. I use a second 3/8" section of XC-132 the same as the primary wick with Nextel, it's about 1.6-1.7 in dia. You can't do without it for reason above.

The two extra pieces of wick in the juice channels are to serve as a form of gasket. When the tank goes below half-full the vacuum holding up juice is reduced. It then tends to flood. As well when the tank gets warm and the viscosity is thinned. The extra wick in the channels is a poor substitute for the loss of vacuum pressure but seems to help deter more juice from seeping down the assembly threads to the 510 connection and your mod!

Good luck malik.

Thanks a lot for the help Mac, very helpful:) Just a couple more questions please, do you have a link that you could give me for a cheap 1.788 drill bit single or in a small set? I'm having trouble locating one.
Also, I know you have a chart somewhere for calculating coil resistance...could you send me the link? If you know offhand, how many wraps of 28g kanthal would yield 1.8 - 1.0 ohms on the 1.788 bit?

Thanks again!

Hope Mac doesn't mind if I chime in..... check out Harbor Freight BK...... My fav place for tools at the right price...lol I've picked up several nice numbered bit sets there for reasonable prices. Hope that helps.

Thanks Horton, I'll definitely take a look.

They don't have any of the sizes that Mac recommended...1.788 (.07", 3/43"). Or at least I couldn't find them.

Have you used 1.8mm with xc-132 in any Protanks successfully? I want the 1.788 size so that I don't have to do any filing or altering of the heads.

Haven't received it yet. 1.8 mm should fit without messing with the heads from my understanding. Haven't yet messed with xc-132. Only cotton atty this point. Will eventually invest in that, but haven't yet.

Get a cheap cuticle cutter from the drugstore. Nail clippers often don't cut close enough. Larger tools are too clumsy. And don't use the tip, I've ruined a lot of good grommets that way cutting into them. And you'll dull the clipper quickly too. Use the side and push in slightly to grab the wire as you push in then cut. That should allow you to cut inside the edge of the assembly Can't do that with a clipper.

+1 When I first saw the cuticle clippers in my Girl's makeup box (was just looking to commandeer her tweezers!) it was love at first sight. Had no idea what they were until she went looking for them and gave them a name. PERFECT cutting tool for coil building and easy to find.

W+C you're alright with that build.
