Forgot to mention, just add machine screw, washers and wing nut to fasten wire to winding handle.

I read this in another forum. Use coil making tool from Hobby Lobby. I bought one and it does work great. Consistent tight coil and the second smallest fits perfect in kanger slot.
Coiling Gizmo Deluxe Econo Winder
sku# 257741
Brand: Artistic Wire
Price was $11.99 and they have a coupon for discount.

True all that wolf…but it won't have that zing if it ain't got that tension. You need tension to get adhesion, closest fit in the universe. Close yeah, but no cigar. And you'll still have to torch to get that close, even with a jig. Good news is you can apply tension as you use a jig. But that can take as much practice as winding directly onto a bit. Gotta recommend them as there are some of us that don't have that kind of fine motion control. I don't some days so appreciate the suggestion wolf. Good one.

It's really ideal to avoid torching anyway. It can damage the wire and age it before use. Also it may limit the ability to actually achieve adhesion. You see it's like two pieces of dry wall you paint and let dry. When they dry separately they're both protected, insulated from shorts. But slap 'em together while wet and BAM! They get adhesion together. Tightest fit in the universe and crazy glue. Doesn't get any better.

Result: Upwards of a 20% increase in efficiency. Less amp draw, greater vapor density, less wasted heat energy for a given resistance, etc.

Here's one I did today with twisted pair for the Immortalizer…

It's a ZNA30 I bought from Lance Wallen (steammonkey) at the Tampa show. Was there doing a promo for a great S FL vendor. It's the only variable I have I can properly do setups on for subΩ research. And for personal use I intended it for the four Immortalizers in my collection. They're ideally 1Ω setups so beyond the scope of most equipment. The ZNA…what can I say…it's a thing of beauty and exceptional of performance and execution. Worth fattening up the piggy for. I'd like another. The ZNA20 would be adequate but would like the Collectors Edition which appeared briefly. I bought the 30 for it's legs, chauvinist that I am.

I chose the pic though brook to demonstrate how portable the technology is. That how much we talk about here is readily adaptable to other devices, other solutions. And this is a rather striking example of that. A couple of pegs up on the difficulty scale because of the device and tolerances, far easier on an iGo-W of which I have several for flavor and wick testing.

I've been vaping other rebuildables for some time and usually at higher wattage than is useful or practical for most people. I'm thinking these days that producers ought to seriously think about fielding 20W devices economically. The market is ready and would really appreciate the ability to transition their dripper tastes to a variable. Then drippers that prefer more typical resistance >1Ω will shine, like the Immortalizer which is an incredible device.

Here's a blue sleeved original on an eVic testing the bottom range of flavor at 7W.

Wow. Zna is PRICEY. That said, may save for it, though after some research, I'm really liking the sx350 chip set. Hoping those get mass produced. Soon.

If I get the promotion I'm up for, I'm definitely getting some new toys.

Good luck brook.

You gotta have at least one awesome original. And if it were just one for me the ZNA would be it hands down. I can run anything on it. And I vape a light t/p on a helios with it all day with the 490. The Immo's are gonna take some work getting it right. I'll skip the Hanna. The Zen has form and function.

Could you explain in detail how to do a tension wrap?
I don't quite understand lol.

I actually understand it but can't get it.

Sorry fella's, I wish I could make it clearer but I'm not as photogenic as my avatar. I am funnier than yippie kai though at times. But sadly, no movie contracts. And I stopped tap dancin' when I was a kid. I'm a MacTech, true but I helped 'em fix the gear that made the media, not produce it. I didn't tell 'em my job, they didn't tell me theirs. That's the breaks.

Short answer: Already was one.

...you don't even need a forceps, or a jig. It really is so simple. Sacrifice a tad of precision of control and pressure. If you bought your wire on a spool…feed it directly to your 1/16 screwdriver (hard to use a bit you need a good handhold). The hand pressure on one side holding the spool and guiding it's exit with the pressure of your fingers, the index finger on the tip of the screwdriver to provide stability. On the other hand the screwdriver turning slowly. Without very much tension at all the wire slides right in line. Very little chance of overlap, or lift off if you apply just a modicum of pull.

Unfortunately, I don't have time to play with the gear as much as I'd like. The coils just have to work. To save time I bypassed detail winding as I described a few posts early. Down and dirty. Your first wrap won't matter. You're turning 14 to get 9. The more the merrier and the tighter the remaining become. Hold the spool in one hand, hold the screwdriver bit with the other as you wind, tension by pressing lightly against the screwdriver shank with thumb and or index finger. Can't get any simpler really. And very natural to release the rotation of the spool with the lower three fingers of the hand. A very natural motion. Not requiring a lot of dexterity. Just a steady modicum of tension. And above is how they come out. One after the other. Ready for installation and compression burn in, wicking and vape.

And here's the demo…


310998d1393677273-protank-3-protank-2-mini-rebuild-options-300254d1390958505-protank-microcoil-discussion-img_0608a.jpg



You'll note a common screwdriver can be used. The largest that will fit will be the most effective and easiest for the Protank at .07" or ~1.778mm (sometimes called 3/43" in some kits). A pin vise can be used and an ordinary common drill blank at .07". These are available on eBay for a couple'a bucks. In the above pic you'll see the long leg leading up which was affixed with ordinary Scotch tape to the handle of the screwdriver. This can easily be removed after winding with the miniature cutter shown in one slice. Real time and fuss saver.

To begin, you're going to need to feed off about 4" of wire off the supplied spool and attach the end of the wire to the screwdriver handle as above. But be careful to not have several feet wind off the spool as you do this. Keep a slight tension on the wire at all times. Or you can use something like a school eraser fit into the spool to hold the coils in place. I don't. It's cumbersome to wind with later. And so I prefer to just keep the wire tensioned at all times. Keep an eye on it or you'll have a real mess. Leave the spool laying down on the workspace you're using and maneuver the screwdriver bit above it until you're ready to pick up both spool and screwdriver.

Once you affix about 1-1.25" of wire to the handle (try to tape over the end of the wire so it doesn't stick you) draw back some of the extra wire back to the spool. Before picking up the spool…proceed to start the first turn winding hand over hand guiding into position with the thumb of your left hand as you rotate with your right. I wind clockwise looking towards the tip of the screwdriver. Once you've laid down the first turn, press that turn in tightly buttressed against the base of the shaft. The spool should still be laying on your workspace with your hands above, right hand holding the screwdriver and base of palm on the spool to stabilize it.

Pick up the spool in your left hand now that you've affixed the end of the wire to the screwdriver. Separate the spool and the screwdriver holding the spool in your left hand and the screwdriver in your right. You may have as much as several inches separating the two. So you want to take up the slack and bring them as close together as possible and find a hand-hold that is comfortable for you. This is one example…


289717d1388483765-i-just-rebuilt-kanger-t3-base-img_0567a.jpg



In this case photo I'm using the edge of the spool as a fulcrum, like a see-saw pivot, but also to add to the pressure I can apply in the stretch. Resting the screwdriver shank on that edge adds resistance. It acts as a multiplier of the press with your thumb and wrist on the screwdriver to the right and away from the spool and the combined pull or resistance of the left hand retaining the spool.

The end of the screwdriver tip is resting on the side of the left index finger. This serves to stabilize the orientation of the shaft so that the wind doesn't go sideways or up-and-down which could skew the wind or make it loose.

Lately, I move the right hand slightly to the right and around the spool away from the left and and use the tip of the left index to stabilize the end of the screwdriver. The important point is to find a way to balance the shaft of the screwdriver. This also serves to balance the pressure being applied with both ends of the screwdriver being firmly held against the tension or pull of the left hand and the spool. The screwdriver resting on the edge of the spool is the balance center.

Now slowly apply gentle pressure of the left hand and right. You will see the first turn tighten on the shaft. And it's time to begin the wind by rotating your wrist slowly and firmly to the right, clockwise.

These first two turns are critical. If you are applying enough tension, and just enough is all that's required, no need to over exert, you will see both the 2nd and 3rd turns line up neatly and tight. So much so at times that if you try to overlap them they will snap into place with a "ping" like a guitar string being pulled. Continue consistent turning but with no more pressure than necessary. This will unnecessarily fatigue you. Even though this can be completed in 30 seconds or less (the typical dozen or so turns) if you press too hard, tense your hands and body too much, you run the risk of interrupting your turns. You will lose muscle control and the wind will go erratic. The flow should be consistent until you complete and you will have an alignment identical to the amazing photo of ribbon above which to my surprise lines up just as neatly with the right level of tension.

If you immediately see separation, you are skewed. :) You definitely are not applying enough tension. It's likely that the spool and the screwdriver are not perpendicular (being held at 90 degrees relative to each other). This will force the wind kind of sideways (skewing) and we don't want that. Check alignment, counter-rotate off the last turn, retention spool and screwdriver and line up another 1st to 2nd turn start from that point. You may need to do this a few times to achieve a consistent adhesion. Keep slowly adding a bit of tension until you see persistent alignment.

Take a break! If you're not getting it, stop. Give your muscles (and vision) time and energy to learn. Set the work aside. Come back to it. Or try another time. It will happen for you. No rule says it has to happen in one session. And some days it doesn't happen at all for some of us. The universe isn't perfect. Some news, huh?

But if you got through that first one, you should be looking at this…


313893d1394460029-protank-cotton-rebuild-way-i-do-img_0535a.jpg



Leave the wind on the bit. Remove the tape with the cutter. Pull the coil slightly away from the shank of the screwdriver. With your left thumb hold the top or back of the coil and with the left lead of the coil pointing down delicately pull the extended right lead down. Tweeze it several times as you go coaxing this lead in the direction of its rotation, in this example towards you.

You now have a completed coil ready to be installed directly in your atomizer coil assembly or other.

(Well that's after you de-wind a few turns to arrive at your desired tight and perfect count. But that's another lesson.)

Congratulations. Glad you stayed tuned.

Good luck.

:)

^^ Great demo Mac!! Wish I could star or favorite that post somehow, that's what everyone needs to see.

... And thank you so much Mac, and everybody else for keeping this thread going. Until I buy myself some spools of kanthal (which I will be doing very soon), there's not much else I can add here. I have yet to try your method yet myself, of tension winding a microcoil, directly from the spool - but I can see from everyone's experimenting & results that this is the best method for building a true contact-coil.

Thanks again everyone for keeping this discussion going, and Mac for the amazing guidance that you continue to provide!
... Btw, I've reallllyyy been wanting that ZNA30 for awhile now. I want to buy myself one for my birthday (end of this month), but it doesn't seem like that's possible. I was looking a couple days ago, and justt missed my chance to get one from electronicstix.com before they sold out. I won't pay more than the original (House of Zen) price, so guess I'll have to wait lol

I'll try to start participating in this thread more often like I was before, have a good weekend guys!

I'm in the same boat... Now I'm looking for a zna (though i read of a few potential drawbacks), dna 30 or 20 or sx350/450 and can't find any. All seem to be sold out and I don't even know how I feel about box mods. Never used one. Makes me think I need to buy an MVP 2 before any other thing.

I digress. Mac, awesome post.

If I understand this correctly, the desired result is that each coil wrap is shorting out to the other wraps instead of being insulated by a micro layer of oxidation?

On the Micro Coils to increase Vapor, flavor & TH: Tension and grip, adhesion, benefits…, Post #10613 I wrote...


...let me share one of my favorite examples of why we need to tension wind. That's what we want to see happen as it impedes shorting. The reasons is that we know Kanthal forms an alumina oxide layer when electrically pulsed. Others and myself have written about this on ECF before. Makes a contact coil possible at all. Now we can do this without contact by pulsing or very irregularly possibly compromising the wire by torching. Great we have that oxidation layer, good start. We just have to get the wire to stick together now.

How about if we just do that from the start?

Imagine two sheets of drywall. Let's paint them. Let them dry. Great, we have protection of their surfaces. Now…another set, paint them…then slap 'em together. Let them dry.

Is there a difference. You betcha slip. They're now fused together, joined intrinsically. That's what we want to see with the oxide layer of Kanthal on our coils. A molecular joining of the respective oxide layers of each turn. Fused, not forced together.

As you can see from my explanation what we end up with is a superior kind and degree of oxidation than an ordinary wind. But you pose an interesting proposition. It's not a short in the classical sense, a part of the element overheating to the exception of the rest, but the entire element heating! Just not excessively and virtually all the coils in unison. Almost magical except we know how we made it happen. It's not a trick or a cheat. It just works.

Good luck lil.

Thanks Mac, I was already sold on using tension in forming the coil, especially after observing the small mess caused by the wire un-spooling itself; indicating the wire was remembering it's former shape prior to being spooled. I have only made one micro coil attempt and wasn't happy with it not glowing from the center out, more like it was glowing all at once. I was anxious to try the kayfun clone for the first time so went ahead. Anyway, I got confused and also am struggling to understand why the coil needs to be so neat but I can see the benefit of a uniform pathway for the electric current, any kink or bottle neck would spell uneven heating. So I do want to learn how to build the best coil. Earlier in the thread was some discussion over the possibility of the coil leads burning or melting the rubber insulator on the protank. That a more perfect coil helps to prevent insulation destruction. Did I get that right?

You absolutely did get the physical mechanics right. A gravel road or a superhighway. The closer we get to a clean electron stream the better the vape. We only want the chaos where wet wick meets coil. The more we can limit it to that the better the vaporization.

That said, I struggled goodness with making tensioned coils…minutely and accurately spaced ones…used screwdrivers…all trying to avoid contact shorts. Let me tell ya, that was far, far harder than what we're talkin' about here. Still you've probably noticed most folks take a little time to get it consistent (loss of tension during wind). It can be done in one sitting but it doesn't have to be.

From your description it seems a common problem, not quite enough tension to get the alignment to happen naturally and perfectly. And it just take s a bit of practice. After I first encountered it by accident, as I wasn't trying to do it the first time, it took me a couple of days to start getting it and a few weeks to get it consistent. For many people, the first time's the charm. Not me either though. So don't feel bad. We need to train our hand-eye-coordination and develop the fine muscle memory in our hands for that.

If it helps, and I absolutely have to have it, try some magnification. There are inexpensive magnifiers available for less than 10$ that are ideal for this type of work (since you're not at it for prolonged periods. I am so I have a professional rig. But this Carson is a perfect example and I use one for demo's. I like the Carson series as it includes a 5+ loupe and is inexpensive...

MagniLamp™ | GN-55 | Magnifiers | Hands Free | Hand Held

Start slowly with very little tension, work on the hand-hold that's comfortable for you and experiment with what makes it tighter as you wind…and importantly, steady in pressure. A kind of continuous flow of rotation once you can sustain the same degree of tension. And it will happen lil, it just does.

Good luck.

been a couple weeks since my last back and forth on here...... and yup, tension is so key....... to consistency......
my ohms have been coming out so close together on same wrapped coils... it's all about tension

you know what else I've found? instead of using a nail clipper to cut off those long legs........ just do a couple back and forths, and then spin the little buggers and they break off nice and clean

just my two cents..

First, congrats on your flourishing good results! And thanks the confirmation of practical results with tension. Those comin' up need to see that. We all need encouragement.

Right now, made more critical and unpredictable by slippery grommets, some are and some aren't, I prefer to twirl the leads off. Problem though…you have to be careful not to skew the coil or an end turn! A little too much tension, there's overload and that side of the coil and it may go slightly sideways. Voila! Loss of adhesion. More energy was imparted than input and you've changed the geometry. It's now slightly diagonal and you're not in a state of fused adhesion. Or…you tension and there's snap-back, a retreat of the lead a mini-millimeter and just enough to create a high end turn. Probably the most common result to twirling or twisting off.

On the other hand, snipping off is often the main reason you're left with a hanger extending beyond the assembly wall. And often it's too small to see (your eyes can play tricks on you depending on the lighting).

It's a conundrum isn't it. Damned if you do, damned if you don't.

But I've pretty much settled in to snipping off though I prefer the other as a cleaner separation when done right. I just always try to thoroughly examine for hangers then. You must.

Good luck kachuge.

Woohoo! Just coiled my first PERFECT tmc. 29 gauge 7/6 1.54 ohms or so on a 1.8 mm bit. Pulsed once, lit up from the center out. One more pulse and it was done. Usually I have to use a little tweezer after the first pulse.

Edit: Aero tank base is changing that resistance. Has dropped to 1.3-1.4 Ohm range on my device. :(

Will have to add another wrap on the next one I build.

I just pulled my old protank II's out of the vape drawer and crafted a nano coil to see what would happen. Wow! It was about 1000x easier than I thought it would be and the vape is amazing above 10 watts.

Congrats v1k1ng. Glad you fared well. Lot's to learn from the crew here. Lot's of landfalls to be made. Don't forget to sail back (with some pictures!).

Good luck.

:)

29AWG, 9/8 .07" 1.75mm i.d., t.m.c. = 1.72Ω √
29AWG, 8/7 1.58mm i.d., t.m.c. = 1.40Ω √

That would be about right gentlemen. Right around my recorded lows posted here on the resistance tables (relatively for a 7-turn, j5). AWG 29 is very versatile and one of these days I'll try twisting it but not really much interested in building below .7Ω. You can get to .5Ω easily tensioning with 6-turns of 29g-parallel and not go through the trouble of pullin' out the drill.

How does one properly tension for a parallel coil (that is what you're speaking about, correct?) I have a great deal of trouble properly tensioning a twisted coil, I could only imagine the difficulty in a parallel.

Woohoo! Just coiled my first PERFECT tmc. 29 gauge 7/6 1.54 ohms or so on a 1.8 mm bit. Pulsed once, lit up from the center out. One more pulse and it was done. Usually I have to use a little tweezer after the first pulse…Edit: Aero tank base is changing that resistance. Has dropped to 1.3-1.4 Ohm range on my device.

Will have to add another wrap on the next one I build.

Back in Feb at Post #652...

Protank MicroCoil Discussion!!: Aeroflow for KPT a great enhancement, not a fix... - Page 65

I wrote that the Aero base wasn't going to be the blade that sliced the Gordian knot of PT problems such as resistance variation issues. We still have the mechanics of the physical design to contend with, I argued. And I've repeatedly commented here regarding the radical resistance changes that have been increasingly reported and observed since then. Far more than after the introduction of the PT2 which signaled the entry of revised (softer) grommets.

Thanks for your observation brook. We many of us appreciate your taking the time to highlight the concern about the Aero bases. I unfortunately corroborate it today with 100% agreement. It is, precisely as you say. I suspect the bases are inducing resistance skew either of their own or in concert with grommet compression. It is consistently occurring, it's repeatable and reproducible (by comparison with results from standard legacy bases). And again, as with the grommet composition changes I have to ask the question why? Doesn't Kanger understand there might be a problem? One not just occurring to rebuilders but vapers using the assemblies the very first time.

It's not by coincidence I yesterday had a focused rebuild session with a partner dissecting this issue. The emphasis on these bases and a variety of grommet configurations. No less than two dozen builds on a limited two wire specs, mostly 29AWG at our common build reference tables. Approximately your build brook. To dispel any notion that user error skewed things here's an example of the precision of the user contribution...

Repeatedly builds had to be discarded because the set, however pristine, when torqued on a mod or carto-meter was affected in the process, one way or another. In some instances caused by the need to take multiple reads as the known target resistance wasn't even close. Repeated examination and manipulation for the suspected hanger/s or internal incidental contact. All in all, the more the handling the greater the risk of crapping your build.

Now it happens that when you build a tension coil you sometimes don't get a bare coil that matches your final pulsed contact coil in res. But we're talking hundredth's fractions in resistance variation. Here we had hangers everywhere, slipping even before any juice insertion (most of these were new silicone). Despite low tension or high in the leads. Inadequate insertion with the pins too recessed in the assembly for contact (no load) due to compression. And the only place of respit were some legacy grommets and bases.

I'd say to some of you see if that doesn't clear some of your problems right up. We'd all benefit and appreciate your accounts. So have it and let us know, will ya?

And good job brook. Really. More on this as I know.

Good luck.
