fireworks in my rm2- help please!

[bander68]

My last few coils have been failures. I keep getting a popping feeling in my mouth, like air bubbles. I took the cap off, and it looks like a mini firecracker pop. Ungood.
This morning I built 3 in a row, all slightly different, but all the same result. I'm getting very frustrated. Superx, I tried pming you but had trouble sending pics from my phone there, so I'm posting it here. This is my latest attempt. It reads 1.15ohm. Using 28 gauge and organic cotton from Walgreen's. Thanks for any help. I really don't know if this is a REO, an rm2, or a wick issue. Kerpow!

Use a little less cotton. - Thinner, not shorter, I mean.

you need to tighten up the spaces between the coils. Fire the coil so it glows. stop pressing the fire button and gently squeeze the coil with tweezers or needle nose pliers. do this over and over until you have a nice tight coil.

don't press too hard or the coil wraps will overlap. don't press the fire button while touching the coil with the tweezers or pliers either.

Wow, see...that's why I like posting here. Responses in mere minutes! I tried both suggestions just now. A little better. But still a tiny bit of crackle. Will check for gaps some more and get back to y'all.

Also does your juice have a high sugar content, you might need to raise the ohms for that juice.

All my coils/builds pop and crackle...I don't know how you've been avoiding it up till now running 1(ish) ohm coils ...the popping and crackling is simply the sugars in your juice exploding (there's even sugars in straight VG, it is a carbohydrate after all)...if it's getting in your mouth go to a longer driptip, other than that, I wouldn't worry about it at all.

Just beat me to it, lol

I have no idea. It's backwoods brew 555 exotic, a 70/30 base with a slightly nutty tobacco flavor.

15 minutes of vaping, and the explosions are gone, but it's still crackly. My old LR attys always crackled, so maybe that is an indicator that the juice is the reason.

I'm still experimenting with coil diameters, number of wraps, and ohms. Not even sure what I want yet since all I've used for the last few years was 1.5.

I tried 1.8 and it was unsatisfying. I tried a 1.2, and it was decent. So today's goal was lower. I'm all about flavor, with a warm (not hot) throat hit.

I'm also thinking this cotton ball business stinks. It's a pita to get consistent.

I almost never get popping with unflavored, Ikenvape RY4, NT Virus or the DIY Peach and Pear that Borescoped turned me on to.

It's also a new coil thing. Run that coil (any of them really) for a few days and the crackling will diminish as the wire becomes broken in.

I like that crackle of a new coil.

Cotton is not for me, i use ceramic wick, specifically Readywick that FB recommended. Lasts for ages.

I was about to say, not sure if cotton has anything to do with it since I don't run that.

 

[Quigsworth]

Agreed, and same...I ditched cotton when I got tired of swapping out wick every 2 days on my .5 and lower builds...I'm also back on ceramic (and sometimes pull out the ekowool)

I'm leaning towards something like that. Re-wicking constantly is exactly the kind of nonsense I wanted to avoid when I bought a reo. I'm being patient right now while I'm still learning, but it's not going to last much longer. This is taking too much time.
I put one of my old attys back on a while ago...and while it worked fine, after a couple weeks with the rm2 I was blown away by how muted the flavor was. So it's obvious- I need to get this down asap. I can't go back to that now.

 

[supertrunker]

I think Quigs is likely correct, i have crackling now on a non-cotton wick with coils i made last night. I have not used cotton, Japanese, Korean, any of it for about a year because it's useless and one dry hit = goodbye wick.

If i were a billionaire or retired, perhaps i'd have more time to mess with it, but those eventualities look rather distant.

I just don't have the time to do that, so i run a Reo with R41 coils, readywick, at 0.3Ω.

[bander68]

Ok, can somebody point me to a good place to buy this ready wick stuff and research it? it sounds like exactly what I need. F cotton.

Wick - RBA Supplies

Sure.

It's expensive, but here's the thing - you blowtorch it after 2 weeks and it's as good as new. Get the 2mm and forget about the 3mm unless you make seriously big macro coils.

I never get the popping I use silica wick . From reading on the forum its always cotton users

 

[olefolks]

Like Trunker says it is not cheap. But, in my opinion, it is the only way to go. As the old saying goes "Set it and forget it".

 

[supertrunker]

I also have a little tip about wicking with it, because i have tried a few different ways and some were dreadful!

If you run it in an RM2, cut it to the length of the atty sides, don't wrap a tail around the back of the posts - it's not necessary. You'll be using a bit of wick maybe half an inch long. That's perfect.

You'll look at it and go "no way is this going to work", but at $1 an inch it bloody well better had!

I think it's cos you have the oldest Reos.
