RM2 / RBA 2.0 / Reomizer 2 Rebuild Tutorial

[Norman Clature]

It depends on a number of factors. I have a non-VV Grand and use cotton for wicks and it absorbs heat so I go minus 1.0ohm all the time. However, if I'm not up to "Super_X" standards and get sloppy with my coil build and have one coil not contacting the cotton a bit I can get some hot juice spurts that burn my tongue. HA!

Actually; sometimes I don't notice it till I put in a fresh battery and then it's evident to me that I need to re-build my coil.

But you know; using an RM2, 30g Kanthal and cotton; making a coil/wick now doesn't take any longer than filling a cartomizer with juice like I used to do. HA!

We really have it "made in the shade..."

Sure is - i just find 0.7 a bit hot, and 1.0 just right! It's all about the Goldilocks zone and consistency is the key.

I now make all my coils the same way - so i can hit the same numbers time after time, 3 wraps =0.67, 4 wraps=1.0 plus or minus 0.01 Ohms. If use only one wire then i can simply double those numbers for my 32g kanthal.

I saw a post from the modfather a few weeks ago? making a 0.3 just to prove it'd not short! But i do know people that use that low all the time. They are 'cloudhounds' - with asbestos cheeks i think.

I'm going to go on the record stating that there's only a few reasons someone would have to go below 1 ohm to get a good vape:

1. The RBA system they use requires a thick wick and isn't feasible for a micro coil. This really only applies to genesis and tank type systems and that stuff. All bottom fed and dripper RBAs i have seen are micro friendly.

2. They are unaware that a 1/16" diameter coil with touching wraps will perform similar to a thick, spread out coil of roughly half the resistance. In other works a 2 ohm micro will perform equal to or better than a 1 ohm spread out thick coil.

3. They are not building their micros correctly.

That's pretty much it. I also theorize that there is a certain perceived "manliness" factor associated with the whole sub ohm craze. Kinda like a "Dude, like, I only vape at like, .212 ohms - One wrap dude, one wrap. You or your mod couldn't handle it bra" thing .

The microcoils are very good on thin ceramic wick, but cotton is a real nuisance because of its very short lifespan.

I'm certain some people get a real manly kick out of making quad coils and such - just because they can, but having watched a video of it, it occurred to me that i could have made 4 or more microcoils in the same period of time.

On the Woodvil, where an RM2 (my atty of choice) will not fit - i have taken to using a killer clone - minus the tank but the coil holder is so small that it has more in common with a Vivi Nova, than anything else. For the rest of them - it's a 1 Ohm coil all the way.

If i were pressed on the issue, i'd have to say that i think cotton has the best flavour of all, but i like to blowtorch my wicks and coils before i install them and silica or ceramic allows that.
I'm also a little scared that running SSLR (seriously stupid low resistance) if like flirting with short circuits and i am not interested in that!

I just happened to use 28ga and wrap at my normal 3 coils that I did for 32ga. If I hadn't cut the wire I probably could have bumped it up a bit. (I hate wasting wick and wire) So I went with it. Next coil will probably be 28g (attempt micro) with silica. Probably about 6 or 7 wraps. Hopefully end up at about 1-1.2 or so. I wish there was an easier way to thread the silica wick. But it is what it is.

 

[supertrunker]

i used to measure a rough resistance of wire as follows: put black probe from multimeter on one bit of wire say an inch and a half from the end and bend the wire; run red probe down the wire away from black one and when you hit about the right Ohms - bend that too. The bit in the middle is what you make your coil from.

A few of us tried ceramic wick and the beauty is that you can get a needle thru the middle of it and wrap the coil on that, so don't have to thread anything thru a coil.

Right now, I have a 5/4 28ga with cotton wick on an unregulated Grand and I gotta tell ya, it's hitting beautifully. It isn't hot at all. It's producing a good amount of vapor (a little airy and a little light in flavor) and the coils are not getting gunked. I'm doing it this way simply because.... it's working.

Do you recommend the micro coil for an unregulated mod? If so, I have some 32ga and I'll build one later on today. How many wraps of 32ga do you recommend on the 1/16 coil for 1.8-2.0 ohm?

I would definitely recommend one for any application where they are feasible - regulated or not. I would stay with the 28 ga rather than the 32 (30 is perfect) because it'll hold it's shape better.

I have never used 28, so to get to 1.8 - 2 ish, I would guess 9 or 10 wraps

"I thought love was only true in fairy tales"....Oh, yes. I built my first micro and what a difference. I used 12 wraps of 28ga and one length of cotton yarn. All I can say is "WOW"! The coil came out to 1.3 ohm even with 12 wraps. Gonna have to get some 30ga and try to get a little higher but this is making me very happy. The coil is a little tight around the yarn but I'll just remove one strand the next time. No hot spots which means no fiddling to try to adjust the coil. I'm getting consistent streams of vapor off the coil...no popping and spitting and the vapor isn't hot. It's the cat's t!ts! Thanks again for the help Super...you're a peach!

what is that green thing?

Here is a photo tutorial of a very easy way to build the RM2. Many of the principals would apply to any bottomfed RBA. Props to Juice Junkies photo tutorial on the original REOmizer for simplifying the process and giving me the courage to try it for myself. For me the photos work so much better than videos, cause you can look at the same one as long as you have to to understand it. It is going to be a sequence of posts, since my coil building skills are much better than my picture posting ones . I have also discovered a neat little trick that makes installing the rolled cotton wick even easier... (it was already easy).
Here goes:

Here are the tools i use:

^ that is a 14ga blunt tip luer lock needle. I got it from wizard labs.

That white stuff is rolled cotton, the black thing is a REO grand, black wrinkle finish and its door.

Also featured are nail clippers, a magnifying light and tweezers.

I should have put a small Phillips head screwdriver and a pair of scissors in there too

 

[Crazy Canuck]

I believe that's his 14 guage needle.

Talk about learning by trial and error!

Since I'm using the cotton wicks, I've gotten in the habit of re-wicking in the mornings before heading out. This morning, I guess I used a little bit too much cotton, and was getting very poor vapor production.

As I was wondering how I was going to last the day on this sh@#ty wick, I realized there was a Walmart on my route to work. I stopped in, grabbed a bag of cotton balls, tweezers, scissors, and some Kleenex, and performed emergency wick surgery in my car in the parking lot.

Much better. Lesson learned for the day, as has been mentioned in these threads... Don't use too much cotton so that there's not enough room for expansion as it absorbs juice.

On an unrelated note, I then got to work, and realized I'd left my laptop on the floor by my garage door, so I turned around and went home again! Now "working" from home... I love Mondays!

Back in my cotton days, I used to tuck an extra pre-rolled wick behind the battery. I also didn't use tweezers, scissors or napkins. Pocket knife works instead of scissors, and I wear my napkins

hi wanna ask i am from ph and i have started doing coils like you do them but what id like to know is how micro is micro something thats like what you guys do...like what can i use?as a pattern?a needle?maybe not.coz our needles may not be the same size as your needles??see my point?sorry for bad english...
and how may loops???

 

[super_X_drifter]

1/16" = 1.6 mm. That is ideal. Anything larger will not produce the same results.

I have great luck using a 16 gauge needle with 30 ga Kanthal A1. I recommend to start with 10 wraps and see how you like it.

Your English is fine. No worries

You can find a nail or drill bit that is 1.6mm too

 

[supertrunker]

i keep a little stack of gear in a desk drawer at work for emergencies, cotton ball, multimeter, tweezers with their own magnifying glass, noalox, spare screwdrivers and an emery board i stole from the wife.

As long as i remember my laptop when i go in the first place it works fine. Never had to use all that stuff, but the feeling of well-being and security is good.

I stopped short of getting a second magnifying headset i use here at home because it would freak them out and i look like RoboTrunk. My wife laughs at me, but i'm used to that.

[zeus01]

now i know this is much too ask, 1/16 is what in laymans term?sorry our country i guess lacks that measurement hahahhaah we still use hand span here hahhaha,lets say is it the same size of a 10ml syringe needle?something to that effect the wire i use is i am not sure thou since the sellers wont say what it is...if you can guess from a pix that woukd be great

[Commie]

Zeus, 1/16 is about 1.58mm. Hard to go by syringe needle size, as they vary

Excellent tutorial, Drifter!!
Have you any other tutorials? I hope to find your lesson with the dual coil RDA. (nudge nudge
