Just got an RBA - Help

[John]

Hi guys,

So I got my first RBAs this week (As I have mentioned in other corners of the forum ). I fired it up with some VK Grape and its so strong it made me cough up my spleen. What am I doing wrong?

Is the Nic content of the juice too high? I'm sure im vaping at the right wattage, about 14w on a 1.0ohm single coil but please steer me in the right direction if thats off. This was on a Lemo

So I thought to try the Subtank with EC Cherry cigar and then I coughed up a kindney, or two. That was on a .5 ohm coil at 17w (I cant get it to go any lower for some reason)

What was the nicotine strengths of the flavours you tried. Also maybe post pics of your builds and setups. Then people will be able to advise you better.

 

[John]

Sorry, I forgot to mention the VK Grape is 12mg and the EC Cherry Cigar is 16mg. The subtank uses the standard OOC coil and the Lemo uses the coil it came with, I just swapped out the cotton with the organic cotton that came with the subtank

The first thing I would check Is the ohm your running. The lower your ohms the hotter your vape.

Next check the coils in relation to the air hols on the top Cap. If they are same hight or above the air holes you will get a stronger thoat it. below the air hole will be less throat hit.

Hi there, welcome to the club, hehe, RDA's are the greatest!! IMO

Two things, Nic can be a bit high, I have seen in my progression from tanks to RDA's that this has happened to me as well.. try a lower Nicotine strength and then also try and mix in some VG to make it more in the line of 70 VG 30 PG... The PG in it also contributes to the strong throat hit that you experience....

so in short, try a lower NIc, or simply go to dischem or your pick and pay, purchase VG Vegetable Glycerin (Pick 's Pay has Dolly Vardon Brand - From Tiger Brands) you can also get it from Dischem, dischem has the Dolly vardon one as well as their own dischem branded VG.... costs like 30 rands for a 250 ml bottle.. try diluting your e juice with this and see if it helps for the throat hit...

be careful not to dilute it to much, you may end up ruining the taste of your e juice, only mix in a bit at a time, perhaps you have an empty bottle somewhere that you can use.. I do this as well and mix in about 1 3rd VG to 2 3rd's e juice...

Hope you get it right and enjoy your vape

The Subtank and Lemo are both RTAs so the air holes are directly under the coils. .5ohm in the subtank and 1.0ohm on the Lemo

Luckily theres a Dischem just down the road, I'm heading over there right now

Ah apologies from your post I thought you bought an RDA. Ignore my advice thats not going to help you much

cool man, hope it helps

LOL we are mixing our own flavours nowadays, only purchasing juice every now and then.. so we are mixing ours @ 6mg nic... when you get used to it, do not try a hit on 18mg nic especially an RDA, lol, it hit me right between the ears, and made me lazy as F@#$ LOL... when we do buy juice, we buy it in like 12mg, when the juice is 50/50 pg/vg so that we can dilute it and get the VG % up while still maintaining a good % nic

Have Fun.. just be cautious as I said, do not over dilute it, you will start losing the taste of your juice...

 

[John]

Thanks bro @JW Flynn I'll play around tonight - will report back later

i have 12mg liquid that I use on the mAN, will adding some VG as you mentioned to give less of a throat hit. I find the 12mg abit to harsh when the coil burns irregular

Yes. It will smooth it out, so to speak

 

[rogue zombie]

Also on the Lemo, your coil position might be a little high, resulting in stronger throat hit.

So push the coil physically lower to the airhole, not too low or it'll gurgle.

 

[free3dom]

If you are using the pre-built coil on the Lemo...FYI it hits like a mofo. Friend of mine (noob vaper) recently bought one and used it and he kept coughing each hit. But on my 1.0 Ohm custom built coil he was fine - exact same juice. I think the type of wire used in the pre-built might also be a contributing factor. It's a thick (i.e. lower guage) wire of unknown origin (pretty sure it's not kanthal). So maybe also try to get some 28G kanthal and build a coil with that (at higher ohms if desired).

Of course if that's what you are doing, then ignore this and go with a lower nic

@r0gue z0mbie I tried to move it off from the deck because I was a bit worried about it shorting out, its about .5mm off the deck now should I try getting it lower?

I actually have a spool of 28g Kanthal. I was a bit worried about the quality of the stock coil - I think its as good a time as ever to practice building coils. Any tips about the diameter and number of wraps for me @free3dom?

 

[Dubz]

@John if you're using 28ga kanthal I would recommend an ID of 2mm. If you have an android phone here is a link to an app that I use to calculate wraps of the coil for my target resistance. https://play.google.com/store/apps/details?id=com.valsoft.vaperstoolbox&hl=en

What ohms are you looking at getting out of your build?

 

[John]

Sweet! I have Vapers Toolbox already, It actually inspired me to develop a better Vaping app - hope to have it in the stores by around 2nd or 3rd quarter 2015

 

[John]

What ohms are you looking at getting out of your build?

I hadnt given it much thought to be honest - was going to aim for about 1.0-1.2ohm? What you think?

 

[rogue zombie]

I think that is close enough actually.

 

[baksteen8168]

Good starting point. I tend to hover around 0.8 - 1.0ohm on a 2mm build. (2mm as i use 2mm ekowool)

On 28g for 1.0ohm you are looking at 13 / 12 wraps on 2mm ( I use a 2mm precision screw driver)
On 28g for 1.2ohm you are looking at 15 / 14 wraps on 2mm

(this is according to the "vapers toolbox" app on my phone.)

Sweet! I've got Silica wick that I bought off VK some time back for my PT coils - is that suitable? I read somewhere that it needs to be boiled? Is that accurate?

 

[baksteen8168]

I see you have vapers toolbox allready.

On my Kayfuns / Russians I tend to use a drill and twist 2 x 28g wires together. Around 8 wraps gets me to 0.9ohm. Flavour for me is also better off the twisted pair

I have not used silica before, but afaik you boil it to get the impurities off. I torch my ecowool before using it.
