railz, try wicking it with more cotton. Kgd cotton if you have it. The factory coils come loaded with tons of cotton and for good reason; more is better with these kayfun style rtas. Use so much that you have to roll it down fairly firm just to get it through the coil. The wicking will last longer too. I'm getting over 60ml from mine with off the shelf cleanish juices. Power levels should be in the 30-35w range.

Would you mind terribly posting a picture of how you wick yours when it's convenient?
I'm trying to get a good visual of what you mean when you say "wick it chunky."

My replacement Lemo arrived today! The flavor is over the top,even using the factory installed coil and cotton wick. It reads 1.1 ohms,and I've been running it at 25 watts,but I keep getting a loud popping from it? Any advice? I was also wanting to build a sub ohm coil,but thought I would try the 1.1 coil out first. You guy's were right!:) The flavor is about as close to a RDA as I have ever got from a tank! I think I have a new favorite now!:toast:View attachment 419576

There's no reason to run a "sub ohm" coil in it, especially with it sitting on top of that 50 Watt iStick. Forget about low resistance and focus on coil surface area. The bigger the coil, the more surface area to create vapor with. Adjust power to taste.

I have 2.5mm coil of 26ga wire clocking in at 1.5Ω, and it's amazing at 20-30 Watts.

Sub-Ohm is for noobs. ;)

As for the popping, try going thicker on your cotton.

for me, it's trying to unlearn wicking they way i was for 8 months or so on the kayfun. This needs more cotton for sure. Burnt hits tells you it's not enough, not enough juice cause there isn't enough wick. I think i nailed it last night on the Drop. Went thicker, and cut a tad longer than i would on a kayfun. This is pretty good, but not a match as it came factory.
I always found over wicking the kayfun would give good vapor, but close to no flavor. So I'll make each one a tad larger than the last till i find the sweet spot.

While mine is not popping now, i would expect most builds/wicks to pop every now and then. Seems to happen when they sit around for a few hours, then pick it up to vape, and pop.

I was hoping this might help somebody, so I took some photos today of the re-wick I did in my Lemo Drop today.

The coil I am using in these photos is 12 wraps of 26ga Kanthal with an ID of 2.5mm, for a 1.5Ω resistance, or so says the iStick 50 Watt it's sitting on. The cotton is from an unrolled CVS Organic Cotton ball. I've said before, I could care less if the cotton is "Organic", but this cotton seems to have a nicer consistency to work with then regular cotton balls.

The width of cotton I use for this coil, torn from an unrolled cotton ball. We'll call it about 1/4 of the total width:

I then gently roll the cotton in the palms of my hand without twisting it. Think rolling a snake with Play-Doh.... I simply like to have some shape to the cotton as I'm pulling it through the coil.

Once that's done, I twist one end of it up between thumb and forefinger to give it a nice point. The point will ultimately be cut off. Poke the point through the coil, and while keeping tension on the back side, pull the wick through the coil. Keeping tension on the back side of the cotton will help it not bunch up. Snug is good, but it shouldn't be so tight it grossly distorts the coil. I find it easiest to do this part with the base installed on your mod, giving you something else to hold on to with your hands while having to hold both sides of the wick. After the wick is fully through the coil, I sometimes like to "squeegee" the wick back and forth a couple times to make sure it isn't to tight.

Pull the tails upward and installed the lower chimney section with tails poking up. I trim them to maybe 3/16" above the lower chimney

I fluff the tails by blowing on the ends a bit with a couple quick puffs.

I have found that technique is important for folding the tails down into the wells and I will describe it as best as possible. Working one side at time, use a small screw driver (my favorite tool is a small eyeglass screwdriver) and gently start pushing the cotton down, actually running the screwdriver down on the inside edge of the chimney. Keep working the screwdriver this way until the entire tail is tucked. There should be no "packing" of the cotton, working it down this way it should remain fairly "fluffy". Repeat for the other tail.

Juice the wick before final assembly. This particular setup is currently vaping nicely at 24 Watts using my favorite 50/50 liquid, but I have vaped as high as 80% VG with the exact same style of wicking. The only extra consideration I make for higher VG, is that once the tails are tucked as above, I take the screw driver and push back in the center of each tail to visually expose the liquid channel.

Hmmmmm.........I have yet to try anything with the ss mesh but have tried my best to familiarize myself with it, are you seasoning it as well before you put it in? It doesn't look like it in your first pic. Sorry for asking you this if you already answered or posted about this build, I've been trying to keep up with this thread as much as I can but on occasion happen to loose a page or two in the process!!

What grade mesh??

It looks like it would solve a bunch of problems folks are having with flooding thats for sure!!

How difficult would it be to try and drop the mesh straws in after you screw on the first piece of the chimney??

It's 500 mesh. I just wash it with dish detergent. The second pic looks darker because the juice saturated the wicks.
I have dropped them in. Just need a long pair of tweezers. Placing them on the channels before the barrel seems easier to me. Also if the wicks are not placed all the way down it floods like crazy. lol

Thanks Jimi, I went back and found your original post with this build and short vid. I've got 3 lemos so I might grab some mesh and give it a whirl!! I've been able to wick mine withoout much trouble flooding them, just looks like something to try and who knows, might be more satisfying for my style anyway!! Like you, nothing I enjoy more than really ripping a big ole lung full of my favorite juice!!

My pleasure NOVA jon :) This build is a nice smooth flavorful vape. I love huge clouds with lots of flavor as well ! :toast: Hope it works out for ya. :)

Good point railz, we all have had to rethink our wicking coming from devices with more limited airflow. Denser wicking brings more juice to the coil but with limted airflow flooding sets in. Less flavor, harshness, excessive throat hit. Trying to increase power resulted in burny hits.

With the Lemo the ample air supply allows for higher power levels to match the saturated wicking and brings with it huge vapor volume and density. Flavor comes along for the ride.

Wicking heavier has another benefit....extended wick life. I regularly vape over 60ml of clean-ish juice between wick changes.

Lemo + DNA40 = happy!

TP with the massive airflow really makes it possible to enjoy great flavor and a healthy amount of vapor!! That and the ability to keep from re wicking as often.

I regularly speak my praises of the Lemo... I will speak again on the basis of temperature protection. This is the absolute best tank (with some slight modifications) for low resistance temperature protection builds that I've tried so far. My builds are .20ohms each and every time, and the connectivity through the Lemo is spot on. No jumping, .20 ohms every time, all the time with my regular build. I think a lot has to do with how the block in the base is so solid/tight against the block screw (especially after flipping the round/white insulator right beneath the block). No floating pins, nice tight connections == happy DNA40 :)
