I'm as happy as a mouse in a cheese factory, but I'm a little confused. I just did my second build on my Lemo. 28 ga. kenthal, 2.18 mm, 10 wraps, istick shows it to be 2.1 ohms. I'm vaping at 6 watts and getting really good taste and good nice plumes of vapor. How is that happening at 6 watts?

Edit: Sorry that was 2.81 mm dia.

Yeah, the istick is crazy. For my 1.3ohm Rose build, I run it at 9.2W on the istick, but like 13.4W on my other mods. The first thing that happened on the istick was I burned my juice and lip. Put it on the inline voltage meter and said wow, this is really inaccurate. I posted about it on the istick thread and they told me I was crazy and it must be defective. I was very happy when Phil Busardo got the same results. They all shut up then.

Which Kayfun version post screws do you recommend? I cant seem to get a consistent reading with nickel wire bc the lemo post screws suck. And my 3 of my screw drivers arent working quite well which is causing them to get stripped.
Wrap your coil legs once around the screws works every time instead of just trying to capture them with the edge of the screw head.

My findings after a couple of days with the Lemo ... using a DNA40 mod with temperature protection / Non-Resistance Ni200 coils.

I'm using a spaced 28AWG Ni200 coil, 3.175mm (1/8" mandrel) with 10 wraps, coming out at .16ohms. I make a contact coil wrapped very tightly using a jig, then gently pull it apart evenly, adjusting as necessary to make sure the coils are evenly spaced.

I've had some odd connection issues ... I fixed this by making sure the base is screwed on as tightly as possible and the pin is screwed in all the way / tight. My mod has an adjustable/spring loaded center pin that is smaller than the outer diameter of the 510 connection on the Lemo, so it fits in there and makes a good connection. I realize the Lemo is supposed to have an adjustable 510 connection by backing out that screw, but I beg to differ.

The stock post screws are not adequate for trapping Ni200 leads. I have a bunch of spares from my Kayfuns - these fit perfectly and work much better. Additionally, make sure you have a screw driver that fits those philips head post screws perfectly; the Philips head in my Stanley precision set was not ideal. I purchased a Precision Screwdriver set at Ace Hardware and the included Philips head in that set fits much better/allows me to torque down the posts much tighter and easier. I'm going to order some more Kayfun screws as spares.

I had a little trouble with leaking on a second fill on one of my Lemos. The key to a non-leaking Lemo is to make sure you build up an adequate amount of vacuum by enjoying a nice hefty vaping session immediately after filling. Additionally, make sure it is sealed properly! I remove both top and bottom silicon tank rings and make sure they're clean, then re-install. Also make sure the glass is completely clean where it makes contact with the silicon rings. I also use small beads of e-liquid on the top and bottom of the glass where it meets the silicon seals, and spin the glass on these seals before tightening all the way. Make sure you put a small bead of e-liquid on the black chimney o-ring as well.

As for the vape ... whoa. It's airy! I tightened up the airflow almost all the way and still pretty airy, but this is when the good flavor started. Nice slow draws with the tightened down airflow and the vape is fantastic. Huge clouds of tasty vapor. Depending on juice, I'm typically around 20 watts (give or take a couple) with temperature protection set at 450F.

I'm very happy with these attys so far. Very simple to build once you work out some of the minor kinks. The Kayfuns will probably be secondary attys for me at this point.

I do. But im always getting a higher ohm reading for some reason.

Need some advice for my lemo. I've done several builds, Maceo, spaced, traditional micro and chimney coils. They all work great on the first fill, but after refilling the tank I get nothing but dry hits. I've used the fill hole screw as well as the rubber stopper. Usually run around 20 watts, but without fail the second fill always leads to dry hit city. Is there something I'm missing?

That would go to prove you are actually getting better connections and not loosing continuity due to loose connections.
All electrical connections, no matter what they are far need to be tight or you will loose continuity.

That happened to me a couple of times the first week I had it. I think I was overfilling it. After vaping some away, it would stop doing that. And since I figured out exactly where to stop, its never happened again. I've had it 2 months now.

As for weird ohm readings, that happened to me a few days ago. The screw inside the base, that holds the positive block was a little loose. Try tightening it.

Mine used to give me dry hits after refills, but it seems like since I started thinning my wick tails to the extreme it quit doing it. :shrugs:

I too had a center post unscrew one time, it really had me scratching my head for a minute. I smoothed the head of the post, especially around the screw slot, with fine sand paper, and it hasn't happened again. It was really chewing up the contact on my eVic, so I'm kinda glad it happened.

My builds seem to always end up reading higher on my istick than what I anticipate, I aim for a 1.5-1.6 ohm reading, if I do the number of wraps recommended by my micro coil calculator I end up with a reading over 2 ohm, sometimes as high as 2.5 ohm. At first I figured that since I'm using twisted kanthal (either two 32 gauge wires or four 34 gauge wires) maybe the tightness/evenness of my twist was throwing off the resistance. Now that I've heard that other people are having the same issues, I'm thinking twice about it. The build I put in there today is reading 1.9 ohm (1.8 mm, 7 wraps I think), I decided to give a try, still getting great vapor, flavor, and throat hit at around 4.3 volts, just wish it was a slightly warmer vape. I think I'll try a smaller diameter next time in order to get a 1.5 ohm reading.

Try a single strand of thicker wire such as 27 or 28 gauge and see if the outcome is the same. A small difference in actual pitch of the twist vs. what was pre-calculated can make a big difference in resistance, especially when you're talking about thin wire like 32ga.

In regards to the Lemo, make certain the bottom base cap is fully tightened or you will sometimes get a slightly higher resistance reading then expected.

God I feel so stupid. Finally got my lemo to wick correctly thanks to rip trippers last video:
https://www.youtube.com/watch?v=fuW9s-tjQjY
I had it crammed down the sides so it would block the channels. Poking it towards the walls and seeing the actual juice channel seems to have solved that issue. :facepalm:
Been trying and trying and my juice always ended up charring on the coils due to insufficient wicking. Don't even wan't to think about how many tanks I've ended up dumping in the sink haha

Finally I get to chainvape this beast. Been doing so for the last 10minutes, so kind of have a headrush/buzz going

Edit: I can't even see the damn monitor between puffs.

So... I have a normal
Lemo and a drop coming in... Bought it specifically for the airflow to accomodate my gigantic Ni200 builds. Anyone have a firm number on what the airhole diameter on the deck is? Googling it yields little, other than "so much better than the kayfun" haha

All three of mine were 3mm when I got them.
