Macro vs. Micro coils (with 26/28 gauge kanthal)

[jj6404]

OK so I did my research first. All I could mostly find for info on the difference between micro and macro coils was the ID. Yes, I know this, and that sort of info is only for definition or semantic purposes.

So let me ask more specific questions:

With 26 or 28 Guage kanthal at my disposal, what are the differences concerning:

1) vapor production
2) wicking (when taking 4 second+ hits)
3) ramp up time

Between macro and micro (and "standard" I guess) coils on an rda with a dual coil build.

What would be the best build for vapor production, staying at 0.35 ohms or above, for use on a mech mod with these gauge wires?

26 will have slightly more "ramp up time". Will have more surface to wick contact thus producing more vapor which will wick more juice.

this is assuming that you wrap BOTH 26 & 28 ga at the same # of wraps, the same ID.

but since you can custom create coils to your choosing, you could wrap your 28 ga coil to "act" more like the 26 by wrapping a few more times to get "more surface" contact or you could wrap the 28ga in a Larger ID to perhaps fit more cotton, thus wicking more and perhaps allowing for more Airflow on the coils which would allow you to run it "hotter".

So... I should use 28 gauge to get a more cloud chasing build?? I thought most people go lower gauges for vapor production.

heres a wicking vid that is good for hotter builds if you use cotton balls and wanna try it >> https://www.youtube.com/watch?v=M1hqRp9TDDE

My experience is micro coils for rdas and macro for rtas. Wicking shouldnt be a problem on an rda and the smaller diameter "for me" gets a tinee tinyy bit more flavor. (hIGHLY subjective!).. The main thing on a mechanical mod is the # of wraps. Using ohms law takes some trial and error but for me 7 wrap micro on say a 2.4mm screwdriver is perfect... More wraps =more ramp up time and less wattage, less wraps= less ramp up time and more wattage... Using macros i will adjust wraps i wont use a full 7 wraps
Check out steam engine it will help you find what heat flux you want and enjoy and will help you wrap coils to your own specs

here is a guide to help you people unsure of what kind of coil you are using.

a micro is defined by its id not wether it has closed or open wraps.

macro coil is wider id than a mini.

and the only reason i post this is cus sometimes things can get confusing unless everyone is on the same page

So, for more vapor, it is more coil surface area. Whether that is large diameter or more wraps on a small diameter?

Yes I understand the nomenclature. My point was that that's the bulk of info that we find online about macro and micro coils. My questions were concerning which type, or more simply, with 26-28 gauge kanthal, what ID should I use to produce the most vapor in a build above.35 ohms

I'd highly recommend the most frequently overlooked gauge - 29 gauge. 8 tensioned full contact winds around a rod that's 1/16" or just a hair larger will get you 1 to 1.2 ohms in single and when mounted in dual parallel (my build of choice) it will net 0.5 - 0.6 ohms.

The heat up is lightning quick and cool down is equally fleet (fast cool down may lead to decreased carmelization).

Here's how I build em - yes, I was acting the funny part in the vid but it produces a seriously kick ayuss coil unrivaled by any other method and I've tried a bunch.

Just look at the perfection of the coils you'll make every single time in literally a minute or two

If you can build low and have good ramp up time with higher gauge wires, then why do all the cloud chasers use lower gauge wire and less wraps?

That's a great question. I get amazing vapor production with the build I mention. I like copious vapor, but I'm not a sport vaper / cloud chaser. I vape to replace cigs. My vape decimates cigs.

I'd add that my opinion of real heavy gauge wire is possibly linked to a "coolness / latest rage" factor and much of that stuff is brought about by sport vapers - those who prolly never smoked and if they did I'd like to know what they smoked before ?

It is also brought about by YouTubers looking for something to shoot a vid about. I mean, even I can only make so many normal coil vids

Battery safety is foremost to me and the builds I make don't even get near the edge of the maximum continuous discharge ratings of my batteries.

I don't do pulse rating because if a mod fires accidentally in your pocket and your build exceeds the MCD rating you will rather quickly understand why pulse rating is to be ignored. I say this because when you build with heavy gauge wire you either need a bunch of winds or a huge diameter to keep it in the safe zone for most batteries

You're the guy that made the long famous battery safety video!

Please answer my question. I just made another thread asking this but I already trust your opinion and I'd really like it.

Using 20A continuous discharge batteries (purple efest 2500mah and Samsung blue inr 25r), how low of a build do you consider relatively safe on a single 18650 in an unregulated mech mod??

I've only gone as low as 0.35 so far but I love the vape on it. Is this ok?

Hey!
Here's a chart, well 3 of em:

Now to answer your question:
4.2v / 0.3 ohms = 14 amps = mighty safe.
4.2v / 0.2 ohms = 21 amps = feeling lucky punk? Not you, just an expression .

Obviously, 4.2v is right off the charger and you will have some voltage drop especially at that low a resistance but I don't screw around with this stuff. I recommend building at or above 0.5 ohms. A slight error in your resistance meter can put you in a whole 'nuther tax bracket so to speak

Here's another vid if you are interested in using a good multimeter

Thank you very much for taking the time to elaborate on this very important topic once again. So, to clarify, pushing 14A on a 20A battery (essentially giving it around 6 amps head room) is relatively safe?

You're welcome

I'd feel real safe running that build

Thank you . Yeah, sometimes you gotta let your inner freak out and that seemed like a good way to do it

That character (Rufus Durden along with another one of mine - Winston Dempsey) also shows up in a vaper collaboration vid a few of us put together about a month back (it's in a playlist on my YouTube channel) and he (my alter ego Rufus) just shot clips to be in another collaboration vid that might be up any time now).
