still off topic, but doesn't all the chargers limit themselves to 750mah max during charge? I don't really see how 500mah would be that much slower, that's why I love my mods with exchangable batteries so I don't have to be without the mod while it's charging. With the istick i would have at least two at hand to be safe. haha

No, the istick has a micro usb for charging. The wall charger that came with mine is 1000 ma. I was wondering if a 2000 ma (2 amp) would be too fast. Sorry for the wrong thread thingy, I'll try to do better.

Ugh, whatever magical wick I created before I haven't been able to recreate. I fiddled around with some different coil arrangements and couldn't make any of them work so I'm back to my super-micro coil. Now I've got a full tank of juice though and a wick that's giving me dry hits. Le sigh....
What are you using for a wick?
Contrary to conventional thinking, I've found more is better.
I don't mean be excessive, but to use a little extra.
If you are using cotton make sure it is snug but not tight, it should give resistance when inserted.
Once inserted move it back and forth a few times, pass the tails through the lower chimney, and trim about 1/2" above the top using a piece of kanthal gently snake your tails across the lower deck, DO NOT pack the cotton into the lower deck, pre juice your wick, test fire, and reassemble.

I think what happens is if you trim your tails to just touch the lower deck after they are saturated will swell slightly and rise up off the lower deck reducing the ability to draw enough juice to the coil, but if you snake the tails across the bottom of the lower deck you always have contact with the lower deck the wick will absorb as you put the chamber under when you take a draw juice will flow up the channels where the wick tails are laying, absorbing the juice and by capillary and thermodynamic action drawn to the coil at the correct rate, the longer tails act as sort of a reserve holding reserve juice until needed, and simultaneously absorbing new juice with each draw.

I'm using organic cotton. I'll give your method a shot and see how it goes. I wonder if part of the problem is that I'm using such a low ID on my coil. The wicking gets very finicky.
I've ran coils with an ID as small as the diameter of a toothpick and as large as 7/32 the key to any of them is to figure out how to effectively get juice to them efficiently at the correct rate.
What I do know is there is a fine balance between optimum contact surface area and proper wicking rate, I know from experimenting what work consistently for me from as low as 15 watts up to 80 watts to produce the flavor saturated vapor that "I" like
I like a warm, airy, juicy flavorful vape, where as some of my buddies find it over powering, but flavorful, what works for me bay not be your thing, but that being said, I can tell you that Lemo if built right will wick as fast or as slow as you want without dry hits or flooding.
If you are going to run a smaller ID coil, you'll want to close up on your airflow and create more of a vacuum on the chamber drawing more liquid in each time to keep the smaller wick saturated, conversely if you are running a larger diameter coil open that airflow up because you have more wick soaking up more juice at any given time, and will naturally wick more efficiently, so yes because this style of atty work off of pressure differential air flow will directly effect how much juice is drawn up the channels, on the deck and to the wick.
Smaller wicks hold less volume, requiring them to need to be replenished with juice faster.
Where as larger diameter holds more volume and can retain more of that in reserve, but this is where you have to be careful too much wick can be counter productive adversely slowing the wicking process when restricted and/or compacted and other times will over wick causing flooding if too much juice is fed to them too quickly.

Now that you are thoroughly confused go try different builds until you find what works for your taste and vaping style, but I can assure you dry hits or flooding is not a shortcoming of the Lemo in any way it's shortcomings in your builds, and lack of understating how it all comes together.

Totally agree with your assessment sir. I'm a Ramie user and have also run KGD with no problems at all. I've been doing this a long time but still screw up a build now and then. It happens, no biggie, next. Enjoy the day!:2cool:

Unfortunately, I don't have power available to me to push larger coils efficiently. I'm getting a new mod, but don't have the money for it quite yet.

According to my calipers my former is 1.9mm, even with expansion for the 30awg wire, I doubt the ID is >2mm.
For some reason you have a misconception about a coils physical size and, resistance, and power requirements
You can just as easily build the same resistance coil regardless the diameter.
lets say you have 28ga A1 kanthal and that kanthal has a resistance of 0.44 ohms per inch and lets say you are shooting for a 1.9ohm coil
your going to need aprox 4.32 inches of kanthal 1.9/.44= 4.318181818181818 now it doesn't matter how big or small you wrap that 4.32 inches of kanthal it is always going to come out to 1.9 ohms period, now does surface area affect vape quality? absolutely, but so does wicking efficiency
6 wrap on 3mm ID is going to give you less contact surface area, but will allow much more wick than if you did 10 wraps at 1.2mm ID but both are still at 1.9 ohms give or take and assuming you are keeping consistent leg length.

Got my lemo, fantastic flavor, unbelievable airflow, very bad airflow control (moves all the time) and...damn this thing kicks like craaaazy. I usually vape at 6mg on my Kayfun, but the throat hit of 6mg on Lemo is super intense.


Same experience anyone?
Read my post http://www.e-cigarette-forum.com/forum/rebuildable-atomizer-systems/601945-lemo-rta-build-pics-110.html#post14802704 to fix moving AFC
And welcome to the Lemo world where flavor and vapor production is a reality you are now experiencing what your juices are really taste like good or bad the Lemo will bring it out.
Questionable juices that are so-so on other attys may taste better or worse, but the Lemo don't lie if it taste like crap it was crap before it's just now more pronounced and concentrated crap, if it was good before chance are it will be infinitely better.

Thank you for the tip! I'll try it for sure.

You are absolutely right about the taste. After my first build, I tried some Five Pawns Grandmaster and It was like...I was drinking the juice from the bottle. I had to add some unflavored VG cause the flavor was WAY too much :)
The only "problem" is the nic delivery. I have to order some 0 nic juices so to mix them with my 6nic that I'm usually vaping...

Yeah I had to cut Five pawns Gambit with unflavored VG
So far Nicoticket is is the only brand I can say is always a wonderful vape, I easily go threw 30ml each a week of Wakonda and Frenilla, and holding out on my PBC and cheesecake until Kent decides to do another short run because my stock of those two are below 100ml I save those for special occasion vapes, Wakonda and Frenilla are my all day vapes that I alternate between throwout the day with an occasional Strawnilla or Virus rotated in.

I'm not misunderstanding Ohm's law. I'm limited in the gauge of wire I can use because I don't have the wattage available to effectively heat larger gauge wire. Conversely, without enough power to overcome the higher resistances of a large-ID/small-gauge coils I can't effectively vape on that arrangement either.

Hence, the viable coil options for me are limited to small-ID, small-gauge to maintain effective heating times.

Finding a solution to the finicky wick is the only available option for me at this point. If I could just build a larger ID coil with larger gauge wire I would've done that long ago since it would making wicking much easier. If I could just go buy a new mod and brute-force the solution I would. I can't, so I'm working with what I've got.

You seem to think I'm attacking the Lemo - I'm not. I recognize that I'm trying to power a device with a severely under powered mod for this type of set up and doing my best to make it work despite being brand new to wicking.

I'll tighten up the AFC some more and screw around with wicking again later. Regardless of my particular limitations I am convinced I can make this work if I keep at it.

    Try less wraps on a larger ID.

    7 wraps on 2.4mm 30ga should give you about 2 ohms

    No not at all, just trying to help, but apparently you still don't grasp the fact that even with what you so have you can build a larger diameter coil of the same resistance and push the same wattage threw it, ....yes a shorter fatter coil more easily wicked efficiently than a longer narrow coil less easily wicked efficiently.

    You have the wattage available to effectively run 28ga wire, and that would be my recommendation.

    For my wife's MVP's, I wrap 10 wraps at 2.2mm which clocks in at 2 Ohms.

    2.2mm just so happens to be the diameter of a piece of coat hanger.

    Wick it as I did in the initial post and I think you'll be pleased with the result.

    Ok, I see what you're getting at now. I figured I would want to maintain more surface area at the expense of ID, not the other way around.

    @VaPreis I would, but I don't have any 28awg kanthal handy. After much .....ing and whining I finally got a 30awg coil wrapped at 7 wraps for 2.3ohms (ID: 2.8mm). It's not perfect, but it's better. 30awg is a pain in the .... to work with.
