Vet needing some rba help

[jamentertainment]

Just started tonight with a aga-t and could use some advice, i have watched a bunch of scotts/petes videos and still having issues, im building with ss mesh and i think 28g wire. When i build this guage wire on a vivi nova i get a nice 3 ohms. But the couple attempts with the aga leave me with just the top coil lighting up and 1.1 ohms. To use this on a vamo, or provari im thinking i need at least 1.5-1.7 ohms, i have tried poking at the coils and still just popping them, started at 3v and worked my way up to 5v..i guess my main question is what size wire is needed on a genisis style to get a good 2.5 ohm 4/5 wrap coil. Thanks

32g should get you close to 2.0ohms with a 4/5 coil. If you are getting a hot spot on the top coil it is likely you have the top coil pulled a bit tight.

 

[jamentertainment]

Ahhh, deff could have been 2 tight thank you..wondering if i did not torch my wick enough as well, tricky stuff

 

[Lhartman89]

Also, did you oxidize the wick and if so how much? I would check what Buzzsaw said though. Having it to tight will cause this problem.

For the wire...28g is iffy without a mechanical mod, my 30g kanthal only gets to 1.4-1.6 ohms with a 6/7 wrap. Try 30 or 32 AWG wire and you should get to where you want...6/7 wrap on 30 for 1.5ish ohms, 4/5 or 5/6 for a 2-2.5ish ohm coil.

As for the oxidization, you don't really need it...there's an unoxidized method out there created by a man Petar K (my favorite method). If you want a description of how to do that check out my blog. Good luck bud!

Stick with it, it gets easier as you learn what to look for. Lots of guys with a lot of experience around here to help us new guys get going.

I think I read the ProV can go down to .8ohms not sure what the Vamo is capable of.

 

[jamentertainment]

Can it be over oxidized?... I put it under the torch for about 10 sec then put it in water 3 times, glowing red each time

 

[KillTheNoise]

Yes, you can over oxidize...however that will only effect the taste output of your wick. If you have some extra mesh and more wire, try out the unoxidized method, myself and many others will testify that it's far better.

 

[jamentertainment]

I tried both, i like testing with the vamo, it was at times .7 ohms...top coil glowing like a light bulb

 

[Buzzsaw46]

Could be, I have heard the oxidized layer can become brittle if over done. I just used a Bic lighter for the two I have running right now, no quenching and no juice burns.

 

[jamentertainment]

I thought u oxidised to prevent a short against the side of the atty, how do u do it without oxidizing?

 

[KillTheNoise]

I'm not completely sure how it works, but I just slide an entire unoxidized wick in and let the coils oxidize the spot where they sit by themselves. Trasher, the guy who taught me how to do this method, has a post in a thread of pictures on how it looks, ill try to find them.

 

[jamentertainment]

Cool thanks

Just to note: Thrasher does his with a mechanical mod. It's difficult to do that method on anything that will "error out" when it perceives a short. With a mechanical mod we can get away with momentary shorts and pulse the coil until it glows evenly. It's particularly difficult on something like my V1 Provari that instantly shows E1 (hard short) with an unoxidized mesh setup.

What's happening with that type setup is the coil oxidizes itself to the mesh through heat (much like torching the wick) as you pulse the coil. It will often begin with the top leg glowing during pulsing and slowly move down the wick until it glows evenly. It's a great way to set up a wick and coil, but much easier with a mechanical mod that doesn't perceive the momentary short circuits.

 

[Plentyobass]

Check for threads in the wick hole. 2 of my 4 came that way out of the box, and were scratching the oxidation off of the wick causing shorts there.

 

[KillTheNoise]

I've done it a total of 4 times on my eVic...yes, you do get a short once in a while, but you simply kill the power and move the wick/coils around until it recognizes the correct ohms again.

There is a learning curve, but patience solves that.

 

[jamentertainment]

I think no matter what i am going to need the 32g wire to help fix this issue, is the 32g thicker or thinner than 28g

 

[jamentertainment]

Funny how re coiling a vivi nova gives me 2.5-3 but .7 - 1.1 on the aga

 

[KillTheNoise]

Higher the gauge, thinner the wire. I would recommend getting 30 AND 32 gauge...32 gauge is easier to use at first, and you may end up liking the higher ohm coils better. However, I have recently discovered I like 30g @ around 1.5ohms the best after believing I liked a higher ohm (like my cartos).

The Vivi nova has long legs that the AGA does not have, unless you are using NR wire for the legs.
