As I've mentioned M, you, PDIB, Supe, Scuba, Vapdivrr all workin' hard towards a non-shorting stable performance coil were the prime influence to me that the corner could be turned if enough of us stepped in. It gave me the confidence not only to try and contribute but that I would survive the experience. Hat's off to you all.

Listen, I got my hands on very early versions of [correction: jig coilers] as they came out. Worked them as diligently as anything that any and all of you put out there. But no I had no input. They do not impart tension. As an investor I would have advised against it as a loss leader or discount item. Not something to get us to the unicorn vape. I think controlled production is for any wind that we try. A winner for every a** at the table, and there's a seat for every one. So I don't see this as a specific wind or form fixation at all but additional dimensions beyond temperature and power that are equally important to the result and our achieving a real control of outcome. Far more in significance and value than any one device we use. My goal has always been getting that developing vaper interested and confident enough to accomplish a proper repeatable electrical wind inside days so they can appreciate what the rest of us do.

As to your center-twist, an incredible accomplishment for a hand wind. I'm afraid my tired old hands can't do it. I've tried. I need tension to get to your symmetry, and turning them as opposed coils (top-turn exit at center) allows them to oxidize as if a single unit. That is, they tend to stabilize as a t.m.c. does with more uniform thermal distribution. The t.m.c. derivative is the most powerful wind I put on std. 3-post. The superbly even thermal output the center twist provides the insulated wind is jaw dropping (as per my pic above). Versions I've tested long term have been by far the best survivors and producers (both flavor and vapor) at every res tested. Recently I've been returning to tensioned versions of your over-under center twist for tests on the Kanger Subtank OCC. It's an amazing piece of work on that deck at 7/64" and 1/8" with 29 AWG performing more like a 26 gauge build at half actual resistance.

Yes the language is changing and I feel necessarily so as we need to consider that factors such as the insulation properties of wire are important to the vape. Wire is not just heat. Or that the internal pressures of a wind can be an advantage in the output over other winds and atomizer choices. In other situations maybe not. At least we have the discussion as the choices matter. But first there must be the choice.

Again, thanks to you and so many that preceded us. Really glad you've joined us. Not tryin' to make ya feel old M, I think I've got ya beat on that score.

Good luck!

:)


Mac,

Ah IC. & thanks for lumping me in w/ some of the greats; tbh even now I just consider myself an overly opinionated d*ck most of the time ;) Can't help but get all gushy & nostalgic from time to time but I can respect that the new thread is probably the same thing, just to different people.

Idk too much about t.m.c.'s.. Like seems there must be an advantage but I've just perused other areas. I'm guessing we are a lot a like in that we take satisfaction in shaking things up a bit. For me it's more about considering the total system or at least fragging down to: atty/mod/ or deeper posts/top cap/switch/etc, getting in there & noodle-ing on it. The best brain teasers are ones where everything is interconnected, like one big knotted ball. I'm a firm believer in easier is harder... as in the more elegant the more pains it took. Case in point I no longer build that build. Was more of a showy time to tinker type exercise. For a long time I was all about dual para, single wire. But, one can never be satisfied for too long, that's just boring :D My current builds are pretty plain: 10 or 11 wrap duals w/ 26awg, lots of testing, but it's more about making superior wire connection in my case. Dayuummn tho, some of those twisted lead para's look prime for a std. tri-post.

I'm perfectly wick right now w/o hot spots, even as hell; can't even push this thing past 4.4v @ 0.6ohms. After I tame this beast your gonna have to show me the t.m.c. way..

Skepticide,

I think I have a way to have a go at your theory of wrapping from the center out. No hints on techniques until I know if its possible yet lol.

I'll try to get to it tomorrow, intentionally winding one with varying attack angles and one as consistent as I can... tension control notwithstanding.

Here goes nothing!

Excellent teaser, now I'm going to have to eat a pound of chocolate to fill the void in my soul. Take pics!

Love that paragraph Matty. Yep, shake it up it is. Turn the problem on it's head and look at it's bottom. LOL

t.m.c.'s are all about strain and what that means to temp. The t/l par is my go to these days as I transition out of t/pair, my mainstay these past two years. In gen I like cool control and clouds on demand. So the straight up build is .3Ω 24AWG. The TLP's I've done have been targeted at the 70% or avg Kay/tank user who's ideal is somewhere in the 15-25W range. These days more convinced than ever that strain's a tool that can keep 'em happy regardless what they wind. But you're right simple and elegant often demands more attention.

Good luck M.

I pretty much decided early on that of the three, considering straight and twisted wire, parallels were the way to go. But unless you enjoy a very hot diffuse output it's not going to be your daily vape. I'm hard core. Min half-doz flavors, ton of devices goin' and most of 'em runnin' bakker. And though I craved parallels for their quick heat delivery, standard wind or torched, they tend to start to snarl, warp and spread almost instantly. Hotter they start, hotter they get and quicker you're restringin'. Sorry it took this long to get to the high power builds but finally the market caught up with the fact that more of us could enjoy some healthy wattage. Finally last year I began with versions of your build and conventional parallels…to work out how to stabilize them as tensioned winds.

I've been running stable TLP's with bakery and tobacco for 'bout a year now and they are the smoothest most effective coils I've ever done. The t.m.c. version of your TLCP is def most powerful and durable. It's not a beginner's build tho, as you know. In comp the TLP is bread-and-butter performance right smack in the middle of the power range. Add to it that it's relative easy to build. I'm sure we can count on @etherealink to breed us some extreme varieties which no doubt will outperform standard parallels but this stuff is sugar and honey right where we need it. I'm talkin' about that 15-25W power range, 31-29 AWG. Same coil stellar on a mech, dripper @ 60W. On a tank build it for density, amazing. Diffuse on a Subtank, awesome. And I've never been a big fan of the latter. You can just dial in exceptional control when you throw thin wire into the mix. It's the ability to vary density with the build, still enjoy the fast heat up and sustain aggressive chaining that just makes this particular t.m.c. wind spectacular.

After you've done a few tensioned winds and see the uptick in (cool) vapor production, the vape kind of opens up to the possibilities. It definitely broadens the comfort zone for workable resistance values as they're stable and don't go hot. Why? Because controlling uniformity (hot spots) is exactly where strain in the wind gets you to. It get's ya home.

Well enough teasin'.

Good luck.

:)

Don't know whether to make a bracelet out of it or use it as a high-power line. :D

Do us a favor…let us know when you're going to fire that thing up. Wanna shut my gear down for the EMF, just in case.

Really great precision work E.

:)

Good luck.

Still plugging away here. I am sorta sticking to the Gizmo and the vice grips. I did do a pretty good parallel I want to try this weekend and did the twist on the the leads and it has stayed tight. I'm trying and I think I am getting it. I have most set up with RDX and I also did a coil on the Coil Master that is mixed in my attys and it's a bit depressing but I can't pick it out of the crowd :?:

Congrats. Parallels tend to warp and spread even when torched. t.m.c. versions tend to stay together. And it's important as gaps will send heat (res) way up and sour the vape. Twisted leads will stabilize even hand wound parallels. But this is about putting all the tools together to max out the performance. When these winds are coherent they can produce awesome density.

Impressed on the ceramic wick P. Put together quite a few of these and have yet to run Nextel in 'em. Listen, I've never been able to overload Nextel at any power level. The wick is made for this kind of coil euphemistically speaking. So do let us know how that RxW build does goin forward. I put a lot of maintenance tips on the RxW REO thread or hail me. You might want to take a peek there.

Don't be depressed about telling them apart. The answer to what's a meaningful build isn't how much production you're seeing when you build it. Sometimes it can be indistinguishable. Properly wound complete circuits will reveal themselves in their consistency. I have a very simple criteria that defines a successful build — do I just keep hittin' it? LOL Anyway P, find that one and figure out what you did! Duplicate that. You're not going to get an argument from anyone if that's what you like.

Good luck.

:)

Mac, I read both of the RDX threads, yeah, both of them. Tried it and liked it. Found the biggest thing was to clean them before you gunk them, every couple of days. They are great for work, quick and easy to maintain. I am even running an ugly coil in one and it's doing well too. I have have found it easy to work with. So anything else I can learn about the coils will just be a plus. It works in maybe not so great coils too.

That sure looks pretty, but I'm curious about the bends on the negative legs. Is that to keep it off the wick?

No, I make em to center the coil on the air slot or, on other attys, to center em between the posts :)

Nextel and a tensioned microcoil is no work at all!

Strongly recommend Nextel for those that can't rewick as much. You'll find compared to other media the flavor potential improves as it breaks in for a very neutral taste/flavor experience that goes and goes like the Eveready bunny. I'm not as ambitious as you in keeping after the maintenance. I try to get to every build within a week or so at least for inspection Basically, if you can see accretion forming on the coil, it's time to the light dry burn in place. That may be all that's required. At some point though it will start as all media does to accrue solids and it'll need a wash or torch. Depends on how dense and pigmented your flavors are.

Yes, Nextel is very forgiving of errant builds. Will not scorch like organics. Will get hot on ya though just as well but it gives you some warning in reduced output. This gives the new rebuilder some leeway getting the symmetry straight. As for the output, I'll differ with ya there. Good coil construction gives you far better production density and requires no more work than makin' 'em wonky.

Finessing an eccentric wind's like tryin' to draw a straight line without a ruler. It's an art form. Like insisting on climbin' stairs when you have an elevator. It's an exercise. Or pouring' oil without a spout. Gonna get messy.

:D

Good luck peppers!

Stylish and functional, I like it. I'm wondering if those bends are changing the resistance of the wire on that side, and how that might subtly affect the coil performance. Unintended benefit, perhaps?

I think I can def see where wrapping under more tension may help a bit with a dual parallel coil. I did a dual parallel with my normal twist and spin and it's really hard to keep the dual wires as uniform as a single. it still works great but I wonder how much adding some tension to this might help in overall uniformity or how much it would matter to the vape. it seems that the 2 separate coils within the one coil assy winds up skewing a bit to each other. you can see how every other wrap is like up/down/up/down etc... do you still get this when wrapping them under tension mac? also I know I didn't twist the legs together nearly as tight as I should have, was a quicky late last night but it does still light up and glow very evenly except for the outermost wrap on each side as you can see from the coloring

That's real purdy however you wound it. I kinda marveled how you oxidized it that evenly with the slight split in that lead. On any parallel if the leads are not equal in length you'll get some diametric incongruity. For any given wind though you'll see a little bit of difference. But if severe some turns may not even line up or contact the bit. Even though all wires may touch those pushed up or down may not be in adhesion. They need to be to oxidize well together or you'll get temp differences in operation. So getting the wires uniformly taught before starting the wind is important…both for the leads as for the wind itself. The proof of adhesion, or lack of it, is at the oxidation burn if it persists in firing mostly inside out or from either end. Let's remember the goal here ain't just pretty but the distributed power brought by equality of strain. It's the vape we're after.


As I mentioned to @etherealink re his TLP, I twist tighter leads. And yes, I pull to tension them with the pin vise. If they're equal (just cut them to length) with a pin vise you can control pitch very well and (often) whether the twist starts at the coil (a bit harder) or the collet. Also, to me, it seems I have to apply more tension to get parallels to adhesion than comparable straight wire. Maybe it's that working off the edge of the spool adds that much more leverage; or, it may just seem so. The math says based on comparable diameter (not mass) that it should take the same strain. The spool seems to add a lot more than I'd thought.

Good luck T. You'll have to tell us how it vaped on that Nup.

:)

p.s. Not a TLP above but a tandem tensioned full-wind I've been testing for some time.

p.s.s. Can I just tell you how difficult it is to post imagery on this forum. How the heck did you get a full text area edge-to-edge image? This was the default and was working for a straight image address convention (current url's). Even posting the image BB code direct which had worked for me earlier (off-and-on) won't. The gallery accepts my posts now after an inordinate wait time with just a few thousand users online. Gotta scratch the noggin' here.

Both coils glow perfectly even and from end to end. This is how I rig most of my coils any more. Here's a vid on how I do it :)

...and as a side note, Nextel can be used for Micrometeorite debris shields and Thermal shields!

Prolly better than polly but not as good as Kevlar. I've no doubt they've got a lot better they're not letting on. LOL

:D Good luck!

p.s. First they admit it, then they deny it.
