Your most entertaining video yet imho. Love the round by round commentating. You know he's going to want a rematch! :)

Yes, there will have to be a rematch because turbo noticed increased separation in Floyd jr when I tightened the centerpost. Footage at the 22:06 mark reveals that he was already separated and bleeding above the right eye (perhaps inflicted when I initially tightened the center post).

But in all honesty, I don't know how to avoid that happening?

The next venue will be in the hellboy arena where there are 2 positive screws - perhaps that will make it a better comparison.

But, I'll add that manny punched well above his weight regardless if his opponent had week knees :)

Shizz...my wife is home tomorrow making filming a no go. But I'll prolly slide down into the ring Friday am and film the brawl :)

before I left work I did a set of duals again and took my time to make them all pretty even and not skewed in any way, took 1/2 an hour :lol: does it vape better than the 7 minute quicky... yeah, actually it does a little. I did also video it. i'm uploading it to check it out

more perfect wraps do taste better to me than splayed wraps, maybe not a night and day difference but you know when you get those builds that just shine as a little extra sweet and juicy and creamy tasting? ones that just really shine? for me it's almost a little bit more creamy of a vape and a little cooler, hard to describe really but that's not to say that the one before it was bad, it wasn't and it still vaped great but this one does vape like there's whipped cream on top, can't describe it better... it's uploading now but here's that build after vaping it all the way home :) yeah one end wrap still moved a little because I had to move them in a bit after the video. I actually broke one leg doing that but had enough length to re insert the tail of it to save the build, this one really vapes spectacular :) yeah, this is the astron, I love the flavor from this thing

ok here's my video of that build. there' is 2 tricks that I use here to get the most even end to end wraps practical. one trick is that I wrap on a 2.4mm rod but the mount them using 2.5mm rods, and the other trick is I reverse bend the legs before mounting, so the coil can be tightened and moved a bit without skewing it, allows for a less stressed coil after installed. stress is what skews it. the coil is a coil spring, the idea is to not to spring it open after it's mounted and installed. personally I almost always get a coil that's perfect everywhere except the first and last end wraps and personally I think that's fine, to me as long as coils 2-9 are perfect, it isn't going to be ruined because coils 1 & 10 aren't fully seated against the main coil, it's still going to work great and coils 2-9 become a perfect vape generator, the skewed 2 end wraps may hurt efficiency slightly from an energy standpoint, but it's not reasonable to try to get perfect end wraps imo, I'd rather insure that everything between the 2 end wraps are perfectly tight and even to me thats as perfect as practical

for me, an even uniform tight wrap to wrap throughout the coil adds a creaminess and sweetness to the vape that I really like. that's actually the one drawback I have to the dna40 with Ni200, I have to space those wraps, Ni does't play well with tight compressed coils, and with a Ni build I can't get the same creamy kind of vape. the temp regulated does shine in many other areas and more than outweighs this minor drawback but I like the extra creamy thickness of the vape when forced through tight seems throughout the whole coil in a perfect compressed coil like these here :)

the video. I really need a better video rig :lol:

How so Mt? LOL From one video of lop-sided firing single?

Proof is in the temperature stability.

Not tryin' to diss Russ here. No sir. We all of us by the millions believed him 2 years ago when he showed us how to get to that 50% boost by goin' direct to the contact wind. I'm only tryin' to show folks how to get a little insurance for free on that bet.

No Mt, you got it backwards bro. Here's a physics question for ya.

How do we unknow what we already know?

No strain, no gain fellas. No contest here.

The question is put, how forming induces strain.

Good luck.

Mac, my biggest problem is installing and maintaining the integrity of any close contact coil. What's the secret?
I know you asked Mac, but for me Russ, I have to have legs that are nearly level and the coil has to be snug on the mandrel. After that it's a matter of not letting the coil move on the mandrel *while* letting the mandrel adjust as the coil torques a bit while tightening the post screws, holding it solid to the deck of the rda will make it deform slightly as you screw it down. Just adjust and reposition as needed after its tightened down and dry-burn to perfection.

mac I'm trying really hard to wrap my head around exactly what you are saying. I even went and said to myself let me try tension first hand and see for myself. I built a tension rig and yeah my tensioned coils were really great, about as perfect as can be, but honestly I did my own side by side like sx did with one tension wrap and one formed and really there was very little difference. the tensioned one seemed to glow a bit more uniform in that the formed one lights up slightly more from the center out where the tensioned one seemed to more come up to glow more uniform, but truth is after the first fraction of a second they were both glowing evenly and pretty much the same, the difference I saw was only withing the first second of firing, if that.

I've also tried vaping tensioned builds right along side formed builds and again, to me, hardly any difference, both vape great. might the tensioned ones vape slightly better, slightly more creamy and fluffy, yeah maybe slightly, half the times it's hard to tell if the difference I think I'm perceiving is really there or just in my head, there that close to each other in vape quality which is why I say tension is a great way to get there but not necessarily the only way....

I haven't bothered with my tensioning rig in a while. simply because I find it easier to just spin a few coils out the way I always have and honestly I don't see any real superiority from the tensioned build to the formed, as long as the formed is uniformly tight and butted to me they vape about the same give or take minute, almost imperceivable differences.

now I have a question, why is it that these coils below can also give a kick ... vape? yes not as "creamy" and "fluffy" as a micro, but warm and juicy and spectacular none the less?

Just clarifying that the first publucized micro coil - this exact one right here actually was called a micro coil because I thought it was tiny in diameter compared to my previous coils (and others i'd seen here). The winds were as close to touching as I could get them at that time on that nail. As we got better and devices which to wind with got better, the wraps got closer and ultimately appeared to even touch, although I doubt they did completely. That coil right there vaped amazing compared to the pic below these ones I ran previously.

Just throwin that out there :)

The original thread was called "micro coil for the RBA on your REO" and it's in REOsmods forum. It was about 2 years ago. :)

ha, and back in that original thread when everyone was on the dark zero jig kick, I was already spinning my coils cause I could never get comfortable withe the up,back,down,front,up,back,down,front erratic awkwardness of wrapping around a stationary object that everyone else seemed to love :)

Mac, my biggest problem is installing and maintaining the integrity of any close contact coil. What's the secret?

Hey Russ, you're right about one thing…a tensioned wind is unforgiving. It'll expose every damned error in wire and wind. We miss that and it'll perform like any other coil.

About a month or so in, I finally got ya. Three days perfect micro's. Then three weeks I could hardly make a one. Didn't know then what I know now. Could've used a coiler then and saved myself a whole lotta writtin'. But tell ya what. I sure am glad I didn't give up.

That said, a formed tight coil may appear to eradicate temp diff's as oxidation sets in; yet, exhibit them in spades as power is later applied. That happens with any and all winds. We've always been plagued with the question — Why do perfect looking winds go hot? A t.m.c. only works right when all the parts are in place — symmetry, adhesion, oxidation and balanced termination. So about the hardest lesson I find to pass on is — leggo that gidget, we love to fidget widget. That is old school. What we've all been doing since the micro is paying more attention to the strain mechanics of our builds. And while we're none of us perfect, that's where the big payoff is…once you've isolated the vaporizing element itself as part of the problem.

You know Russ I wrote about this as my very first starting principle almost 18 months ago. Fix the wind and we can find every deviation in our build approach and style, stabilization. And a stable circuit wound to a metric is the foundation of that. Loose coils aren't that and I could never endorse that.

Not if we want to beat the factory build.

Give you this Russ, a coiler is a functional means to formed symmetry. You can apply enough external force in your wind to internalize a slight internal rigidity. You can learn to splay those winds and get precise turn to turn spacing.That is an advantage over trying to craft a spaced wind which is utter futility for most of us. This isn't art class. Tho not knockin' it if it is. We're talkin' bout the vape here. Good even non-contact oxidation. A proper electrical coil. So for those trying to build spacers, have at it.

I think tension winding the same separable open wind as above on a pin vise provides molecular stabilization of internal strain even for a spaced wind. So not the whoopass that your micro gives on tension but a boost. Because resistance has been normalized over the wind which a coiler cannot do. So why not wind a spaced wind in the most stable state possible electrically?...applies too!

Dunno Russ. Wish I could join ya.

A tensioned micro allows most folks...not you, not me..the most direct path to symmetry and good electrical performance. That's what they tell me. Who am I to tell them they're wrong. You see Russ, that is your dilemma. I find temp variations when strain is distorted or absent, the very cause of the vape headin' sour. Because strain is always there, it must be dealt with. And when you do that 50% is recoverable with a t.m.c. And brother I'm after that 50% 'cause I'm a tootie puffin' unapologetic cloud chasin' chucker plus everything in between and I'm all in on this deal.

Always gonna be folks like their 35 psi radials at 28 no matter how good the facts or arguments for milage, safety, whatever. Mazel Tov! I'm only kickin' the tire. And I'm not here to spoil anyone's parade. For all I know they ride good in the mud.

Hope y'all sort this out soon. Millions of folks out there hopin' we (vets) have the answer and not the riddle. We can confuse 'em and lose 'em.


Good luck.

mac, I just want to say again that I'm not trying to disprove, discredit or debate you, I'm more just trying to wrap my head around exactly what it is you are saying and trying to see what you see but I've tried and tried and I'm just not seeing it. I'd like to hear why you might think that an obviously spaced coil with no attempts at butted wraps can still vape great.

you asked a few times now: "The question is put, how forming induces strain."

by this do you mean that the wraps of a tensioned wind are constantly being pushed against each other? or are you saying that the strain in the wire adds something to it's properties?

in order for any sort of metal to be formed it must be pushed past it's natural resting state and deformed, it will be strained at the point it is formed and when pressure is released the metal will have a new static resting shape, the strain is at the point it was deformed past deflection, and it for the most part holds it's new shape except for a bit of spring back and after it is formed yes there will be some residual strain in the grain structure of the metal. in other words forming does add strain because it is taking a straight wire and turns it into a coiled wire, it is strained into it's new coiled shape. with wraps done under tension the main difference I see is that because of the pulling force and the tighter wrapping, the coil will have been put under a bit more strain yes, and this is evident by the fact that a wrap done under tension will spring back a bit less, but it still does spring back. both have been strained enough to rest at a static position of being coiled. it's the strain that made it go from a straight length of wire to a coil spring. I'm just not getting how you are saying that because the tensioned wrap may have had a bit more strain as it was wrapped, how that makes any kind of difference in the vape? to me the main difference in the tension is going to be the amount of spring back, under higher tension a coil wrapped on a 2.4mm rod may spring open to 2.48mm where just formed may spring back to 2.53, but other than that I don't see how there would be much difference in the properties of the wind

as far as the coils pushing against each other more so than just formed, again I'm not getting the hows or why's that would make you come to that conclusion. even if there was a way to introduce the coils wanting to push against each other even closer than just touching, that would be negated as the coil is glowed and the wire gets annealed, once the wire glows and gets annealed the grain structure in the wire will relax and actually relieve any residual strain left in the wire, so really in the end once the coils are glowed they are annealed and the grain structure re aligns and the stresses are relieved. I'd really like to understand what it is your talking about because I do believe that you believe it and I know you've put a lot of thought and energy into this and I feel like I'm just missing something or not understanding something....

:danger: Long & Technical :danger:

I started vaping almost a year ago and have been following Mac & Super_X’s threads for ten months or so. Their efforts have made mine much more productive. These gentlemen are vaping heroes. Thank you both!

I wound my first resistance coil 30 years ago in high school electronics shop, along with motor coils and other nifty experiments. In the process of designing and building special effects for the entertainment industry, I have had to custom wind various types of resistance coils over the last 20 years.

It seems to me the most important things we look for in a good microcoil are:

1) An easily and accurately repeatable/duplicable process.
2) Even and symmetrical; from wind to wind and end to end.
3) Abutting wraps.
4) A complete layer of oxidation covering the entire coil.


I knew from the beginning that at least some tension was required. This tension is what allows us to successfully lay each wrap against the previous. I first hand wrapped coils with limited success. I moved to a method similar to turbocad6’s which seemed to work great for 32-30g Kanger coils. As I adopted RTAs & RBAs, turbo’s method played havoc on my tender fingers. Then a cigamajig (thanks cigatron!), directly off the spool got me close but the tension varied too greatly from wrap to wrap. Finally, I home-built a jig similar to the gizmo: a drilled 2x4, secured in a vice with a custom-bent 2.4mm coat hanger for a mandrel.

I’ve stuck with this last method, with a few small tweaks, for the last six months. In my experience, too much tension is worse than not enough. Kanthal A1 has enough variability from the factory. Introducing uneven tension throughout the process just increases the variables in the wire. Human-applied tension is extremely difficult (nearly impossible) to accomplish in an even manner. With enough practice we can probably get “close enough”. I have found 5lbs of even, static/mechanical tension perfectly fine to wrap coils with wire up to 26AWG. I also question whether excess tension skews a coil in ways I'm not currently grasping.

It appears that a layer of Al(2)O(3) over the entire coil is what makes a contact coil successful. Without this non-conductive “ceramic coating”, the “effect” cannot be attained. This alumina makes up for any slight variances in our process or, indeed, the wire itself. In other words, the “effect” seems to be all about the oxidation on our contact coil. Have a contact coil without a complete layer of alumina? No “effect”.


A couple of questions to ponder:

During the oxidation process, we gently “rake” the coils to allow for alumina to form between the wraps, thereby permanently separating them.

-Considering this, how perfect does the “adhesion” have to be prior to oxidation? Given reasonable wrap proximity, does the oxidation process provide the necessary adhesion to reach the “effect”? Is the oxidation process noticeably shorter for a microcoil wrapped under tension? How much tension is required?


Our traditional methods of coil winding (pin vice, cigamajig, gizmo, etc) require us to guide the wire by hand, necessitating tension to make up for human error/imperfection. A mechanical process removes the human error quotient, guiding the wire predictably and repeatably, laying abutting wraps.

-Is the coil master (and its ilk) enough of a mechanical process to prepare the coil (wrap proximity and symmetry) for oxidation without the need for tension?


In short, many vapers now define vaping heaven as the “effect”. This requires an alumina coating over the entire length of the wire in our symmetrical contact coils. As long as we prepare the coil symmetrically, with touching wraps and a complete oxidation process, does it ultimately matter in our vaping experience how we wrap it?


Given individual preferences in vapor density, texture, temperature, throat hit, flavor, ease of use, etc. and the numerous differences among atomizers; perhaps the much bigger question is should all vapors go in search of the “effect”.


Thank you all for an enlightening, civil exchange of thoughts, technique and camaraderie. :)

I want to stop here say something. I believe in capitalism, the free market and firmly that we each know better what to do with our own damned money and enterprise than anyone. And that applies to a coiler as well as any idea. I'm not downin' anybody for trying one of these things. I have. Several. And the experience was well worth it. And maybe someday I'll find some use for 'em besides pretending to be a penlight in my drawer. So no, I'm not trying to discourage experiment. I applaud it. And does it break my bones if some don't get it? WTFAI to say? I'm here first and foremost for those struggling trying to find the kickass starting point that get's 'em through.

...more perfect wraps do taste better to me than splayed wraps, maybe not a night and day difference but you know when you get those builds that just shine as a little extra sweet and juicy and creamy tasting? ones that just really shine? for me it's almost a little bit more creamy of a vape and a little cooler, hard to describe really but that's not to say that the one before it was bad, it wasn't and it still vaped great but this one does vape like there's whipped cream on top, can't describe it better... it's uploading now but here's that build after vaping it all the way home :) yeah one end wrap still moved a little because I had to move them in a bit after the video. I actually broke one leg doing that but had enough length to re insert the tail of it to save the build, this one really vapes spectacular :) yeah, this is the astron, I love the flavor from this thing...

Heard all that. And I agree. I build spacers all the time for contrast both tensioned and not. More so, the multi-winds everybody raves about. And it's a lot of work as they're not all for exhibit here. But functional quick and dirty rip 'em out. Hey guys, I've only got 70 of these devices.

I think the point you make is typical of the kinds of anecdotal reports I make note of and validate because you post your builds and specs. I've tried to repeat a lot of the builds you diligent posters put out there. One proposition which continues to be tested is simple…more production, more flavor more vapor. However, it can't be heat. If the vape gets hot, the energy is getting diverted from the wick (work). I've talked about diffusing or dispersing the vape and ways to do that. It's vaporization that gets us flavor and vapor. Turbo when vaporization explodes is a narrow zone for a while I thought was error. A failure of the build. Vape output temperature dropped. The senses were baffled. Why was I getting more output with less heat?

There wasn't…the heat is absorbed by the vapor. Airflow doesn't cool down the vape. It conveys it. The juice absorbs the heat. So radical accelerated vaporization must be accompanied by cool down. And that is evidence of effective phase transition. Want higher temp? Drop res or more power. Build for that.

Like I said, I was the biggest skeptic of Russ' micro. And then, adhesion itself. Thought both wrong and downright failures.

While I have heard from countless people from all over the world confirming this simple principle. I need help. I can't do this alone. Assume for a moment, if this exists turbo how important is it?

I don't want a contest. I want an appraisal from all of you who have a stake in this game as a vaper and member of this community to validate this phenomena. The more it happens, the more it can be validated and passed on to others who need it.

All am sayin here folks. We could sure as hell use the company.

Good luck.

Thank you all for an enlightening, civil exchange of thoughts, technique and camaraderie. :)

I have been following this thread for quite some time, and much of it being over my head, I have enjoyed reading and following along. It suddenly dawned on me, after reading the above by aldenf how long this thread has gone w/o degenerating into name calling, and childish rants. Not something you see very often. But I guess this is what mature adults do, and it's good to see. Thanks. This is something I just wanted to comment on. :)

As for my country input, my game has always ALWAYS been about getting the best possible vape using the simplest most duplicable means possible. Peri-...-id. That is it. No other agenda. If I can help along the way, he'll yeah, that's awesome. But I'm really not that into what others do to change what I do just for their sake. Call me a selfish bassturd. It's cool. Been called a lot worse and still walked away laughing.


I've been sucking vapor thru a tube since September 2012. Not one cig since then.

All I can say is to my untrained senses my vape game has improved by several major milestones along the way. In order:

Unflavored nic base
Bottom fed mods
RDA
Micro coil (the small size version initially not the YouTube celeb big contact version)
KGD

Since then there have been minor improvements and zero steps backwards.

And to my untrained lips, mouth and lungs I can say with all honesty that the coils I've been crankin out for the last two weeks equal or even exceed what I was vaping prior. Not game changing cause I already has game right?

The thing that has changed is the ease and simplicity in which this old dog can make that kick ayuss vape.

Remember I have girl fingers - just look at how cracked and dry they are. That's from OCD hand washing.

So I couldn't use turbos method.

Wire gizmo - great stuff but not as easy as coil master.

Pin vice - no patience for it. To difficult for me to duplicate.

So I'm good. I'm good with where I'm at right now.

It's gonna take someone showing me what I'm missing to make me blink at this point. My vape is insane. Has been for years. And I'll add that if it involves much more than I do now, it would have to really rock my world to unforeseen levels to get me to do it.

Like I said, life's short, wife's hot and kids are young. Clocks ticking and time is money. So Ima kick these tires an light these fires and take a kick ayuss vape in honor of all ya'll :)
