The Lemo RTA: A Build With Pics

[RedheadedBStarD]

I decided to try something new (again) in my Lemo Drop. I installed a triple 30 gauge parallel build measuring 13 wraps on a 1/8 drill bit for 1.5 ohms. Longest coil I've ever made lol. Was a pain in the .... to wrap and install, but works pretty decently though. Seriously doubt I'll be able to rewick it without damaging the coil when it comes time, so I'll wrap another at around 1.2 ohms for a little faster ramp up and attempt to remember to take pictures.

For the AFC nut, any spare o-ring that fits snugly on the threads will do the trick. I've used o-rings from drip tips I no longer use, or a spare kayfun chimney o-ring should also be a nice fit.

For setting the air flow, I usually leave the base off, then stick the Lemo on my palm to test the draw until it's adjusted the way I like. No need to keep screwing the base on to test it.

I never had much luck with O-rings. I was using rings from drip tips, sometimes they worked and other times they didn't. I don't think they were tight enough, maybe I needed a smaller size. Recently got a Drop and it had a really loose adjustment ring. It would go to full open or full close after using it for just a few minutes. In the end I tried Teflon tape. It was fiddly to cut strips narrow enough that they didn't obstruct the air holes but I got it done. With 2 thicknesses of tape it was still too loose. It took 5 layers of Teflon, which says something about how loose the ring was on the threads. At that point it was tight enough to stay in place, but loose enough that I could still adjust it with a toothpick.

I don't think the rings on my full size Lemos are quite that loose. I'm guessing each one will take a different number of layers of Teflon. I've only done the one so far. I've used a lot of Teflon at work and it's pretty tough stuff. Hopefully it will last a long time. Might need a bit of extra care during cleaning. And I'll keep an eye on it to make sure there are no loose scraps that might get sucked up into the tank.

i switched mouthpieces between my new subtank mini and my lemo drop. Wide bore stopped my burnt issues with the drop and made the sub tank mini better..stock 1.2.

I do not think I have a single drip tip that is not wide bore

After using the lemo for well over a month i am convinced its the best rta that i have tried i have 3 of them now lol..

Finally got to rebuilding the drop with another triple parallel 30 gauge. 1/8" ID ohmed out at 1.2.

Nice looking coil Red. When I went from a single 28 Ga. Kanthal A-1 wire to a Double Twisted 30 Ga. UD Kanthal A-1 at 8 wraps for 1.5 ohms with a I.D. of 2.5mm, the flavor and vapor really came Alive, and I've never looked back. I've also tried the same Double twisted 30 Ga. on 3mm and 3.5mm and just adjusted my wrap count from 8, 7, or 6, It's ALL GOOD. I get my UD Twisted wire from several sites, It's alot easier for me just to buy the 30 GA. already Twisted. I can run it up to 35-40 watts if I want, but I tend to keep it at 13.5 watts on my Leeeemo's AND Drops, also my just bought NEW Leeemo 2, they all work out the same for me. Happy, Happy Days.

WoW, did I ever screw that Reply up. Focus Danial-Son. Those are your Pic's Red, NOT mine. See, thats what you get when ya let an Old Fart on these forums I guess.

Looking at the Lemo 2, it obviously was designed for cloud chasing since it is adjustable for some pretty high airflow.

However, would the Lemo 2 be ok for someone that makes a single 28 AWG Kanthal coil in the 1.7 ohm range and powers it with just 10 to 12 watts? ... I also do mouth to lung hits with a pretty tight airflow.

The original Kayfun Lite-Plus I had worked real nice under these conditions .... How about the Lemo 2?

Thanks,

YES Flt Sim, You can definitely do MTL and Lung Hits with the Lemo 2. I'm 90% to 95% MTL on mine and run as stated above at 13.5 watts but will occasionally do 20-25-30 watts, just for Kicks. You want tight ? I can completely shut OFF my air-flow, or, open it up Wide Open which is More than my Magma RDA is at wide open, or any setting in between, just be sure to put a small amount of e-juice on a q-tip and lube the air-flow adjustment a bit or else I have found that on one of mine ( I have 2 Lemo V2's ) the air-flow is a little tight and this helps to smooth the air-flow controller out so that you can get it closed tight if you want ( or need to on re-fills ) as it's a bit sticky and doesn't want to close off all the way, my other one is just fine. I guess that that's some more of the good'ol Chinese Quality Control at work here. I also build at 1.3 to 1.9 Ohm range so that covers your sweet spot. Occasionally I have trouble on my re-fills ( still getting used to the V2 of the Lemo ) as I'm so used to my Original Lemo's and Lemo Drops that I forget that the version 2 is just a little bit different on the re-fills and over-fill the darn thing on occasion, then I've got a mess, but I'll get into the swing of things here shortly. I Very Highly recommend the Lemo V2. As a side note, I have run from 50/50 all the way to Max VG in All my Lemo's and just do a slight adjustment on my wicking and the V2 is good to go at any wattage. It's a Fun little RTA but it does seem to go thru the juice faster than my Lemo's v1 and my Lemo Drops. Some people complain about theirs just drinking the juice, but at the same time complain of getting Dry hits. I wonder where all their juice is going to then ? If you get a Lemo v2 you will prolly like it alot, I know that I do. I hope I've answered your concerns, Catch me later.

Edit: You might want to do as I did and get that goofy "tail pipe off of a Harley Davidson" of a drip tip out of there and put a more appropriate drip tip on, like one from a Kayfun or like me a Taifun drip tip, I think you'll like one of those a LOT better. My Taifun drip tip opening is like 5mm and the chimney on the Lemo v2 is like 3mm, the stock Lemo v2 drip tip is like 10mm. I don't know about you but with the stock drip tip I felt like I was trying to "Suck Start a Harley" every time I put that thing in my mouth. It just felt Wrong.

52anddone ....

Thanks for the great response. I really appreciate the information you have provided.

I think I will get the Lemo 2 and build on it basically the same way as I did on my Kayfun. I noticed that very wide mounthpiece on the Lemo and will be replacing it with one of my old Kayfun tips.

I really liked that Kayfun, but unfortunately I misplaced it during a night out on the town while being over here in the Philippines ... that will never happen again. And to think, that Kayfun cost me $110 after ordering it from Germany.

oh well ....

Sorry for the delay on getting back to you, I had just gotten out of the hospital on Sunday and am just now feeling like my old self (first time back on the computer).

$110 is alot to lose for such a nice RTA, sorry to hear about your mis-fortune. I think that you will like the Lemo V2, But, Realize that every RTA is different and has it's own ways. That being said, from what I have read here on ECF, The Lemo/Lemo Drop/Lemo V2 are like the Kay-fun's but NO dripping/leaking and with better air-flow and thats about it, which is really alot in my opinion. The Lemo V2 does have it's quirks though. It WILL leak when you do re-fills if not done properly, It WILL leak if not wicked properly. If those 2 things are done correctly you will not see a drop. I'm just on the cusp of getting it right myself, as sometimes I have absolutely NO problems at all, and sometimes I do (when I'm NOT paying attention to things). I have heard it said that the Lemo V2 is Finicky, but stop and think about it. The Lemo V2 is not made of plastic that can bend, warp, or get out of shape from 1 re-fill to the next. It's made out of stout metal that cannot change (unless somehow damaged), so be aware that If 1 refill works out Great, and the next re-fill leaks like a sieve, then it's prolly something that you either did differently or didn't do at all from the last time when it all worked great, you just can't Half ... it on building or re-filling, and please don't expect it to be exactly like a Kay-fun (or any other RTA cause it ain't). Alot of people expect it to be like the last RTA that they had and built on and it's not, it IS different, but a Good different when you take the time to learn the little in's and out's, just like all the others. I think that you'll like it coming from a Kay-fun though, I can Tootle Puff, or do full blown wide open Clouds, and anything in-between. Have Fun and Vape On.

Hello all,

I finally decided to try a rebuildable tank after using carto tanks for the last couple of years, and bought a first generation Lemo on a closeout deal. I like the carto tanks, but it seems like the quality of cartos I've been buying for the tanks have varying quality lately, and I also think it should be cheaper to build my own.

Wow! I'm getting much more flavor and throat hit than with my carto tanks. so much that I dropped my nic level from 6mg to 3mg and even cut my flavor percentages a little. I was using 70pg/30vg juice, but made the last batch 50/50 to try to help with less TH and more vapor, and also thought it might be a little less prone to leak or flood with thicker juice.

I've read through most of the 160 pages in this thread, but my problem seems to be the opposite of most people here. The vape I'm getting seems too "wet" and hot. There's some slight gurgling - it seems to always be on the verge of what a flooded carto felt like, but not quite. I'm using 10 wraps (maybe 11) of 28g kanthal at 2.0mm diameter, which gives me about 1.9ohms, and wicking it with Japanese cotton, "bunny-eared" and cut about 1/4" above the chamber, then stuffed down into it and covering the juice channels. I've tried running it at everywhere from 7 to 15 watts, and have settled in at around 10-12 watts most of the time. Lower wattages didn't seem to produce much vapor and I couldn't handle the hit at the higher ones. I also tried 28g on 2.4mm and 3.0mm, but they seemed even wetter and hotter. I also played with the airflow, thinking that an airier draw would not pull so much juice into the wick, but it didn't seem to make that much difference, so I closed it up again to be more like the carto tanks I'm used to, but a little airier. I've tried less wicking, cutting it off at the top of the chamber instead of above it, and tried not covering the juice channels, but this latest configuration seems like the best so far.

But it's still a little harsh for me. What would be my best bet for getting this Lemo to vape similar to a carto tank, but with the better flavor and vapor without being too harsh? I have been using Boge LR (1.6-2.0 ohm) tank cartos. Would a smaller gauge wire and/or smaller coil, like maybe 30g on a 1.2mm or 1.6mm bit get me there? I haven't tried that yet because I only have the 28g kanthal and the wire that came with the Lemo (26g Nichrome?) on hand, but will order some if it will help. Or should I be looking at a higher or lower resistance coil? I was also wondering what effect the height of the coil above the airhole has?

(I also got a Kayfun Lite (clone) that I'm having similar issues with, but not the same degree. The airflow on it is fine for me, but the vape still seems a little wetter/hotter than I'm used to. I've tried using the same builds in it that I'm using in the Lemo. I figured that any suggestions I get for the Lemo should work for the KFL, too.)

EDIT: I was also wondering if I should try a different wick than cotton, would silica or rayon make a difference in the amount of juice I seem to be getting?

Thanks for any help you can give this rebuildable newbie,

Dave

At 1 year old I did an overhaul on my Lemo today. One of my seals had a tear, and the other had some tiny cracks. I replaced both and the chimney o ring, and its good as new.

You may try raising your coil above the air hole more to see if that is more to your liking. I didn't think about it before, but, when I finally got the Lemo V2 I then realized that my Lemo V1 WAS a bit wetter as to the vape. The V2 seems a bit dryer and cooler than the V1, don't know why though, but on my V1 I do place my coil down low, same as my V2. My V1 also gurgles more than my V2, but no flooding of any sort. VaPreis is the man to ask about the Lemo's though, he wrote the book, as a matter of speaking. Have Fun and Vape On. Also, be sure to lube up your O-Rings on assembly each time and you'll find that they will last something like Roxy's (1 year), that's fantastic.

Well, I did manage to get my hands on a piece of 30g kanthal, wound 8 wraps around a 2mm screwdriver. It came out to 2 ohms and I put it in my KFL, since I had emptied it because it was leaking pretty bad on its side and was going to try rebuilding it anyway. I wicked it with Japanese cotton, using more than I thought I should, pretty much filling the spaces between the sides of the deck and the chamber, and covering the juice channels. It worked out pretty good for me, I can vape it at 8-9 watts and it feels similar to my carto tanks, but with more flavor and more vapor. Just what I was looking for. And it hasn't leaked yet when I left it laying on its side for a couple of hours several times today.

I've ordered more 30g wire, and when it comes I'll try this build on my Lemo, and raise the coil up more over the airhole when I do. I did change the Lemo drip trip to a delrin one from my carto tanks, and that seemed to help a little, but it's still wetter and hotter than I like, and makes me cough.

You have to build a Lemo large 2.0 or above and really STUFF it full of wicking. Much more than you would think
