My first RBA rebuild pic, need pointers and input

[Muggs]

So I grabbed a cheap rba and had at it. This is my first attempt. I haven't gone through all the threads like I should but between work and the kids it's a lot of material to cover so I'm hoping you guys can throw some pointers my way based on what you see.

It was a cheap kit but man this thing barely kicks any vapor on both of my mech mods and an eGo on 4.2v.

Specs:

X1 rda Rebuildable Dripping Atomizer
3mm odorless silica wick
0.5mm X 0.1mm A1 resistance wire

Looks good. I would suggest evenly spacing out the coils or do a micro coil if thats what you were attempting to do.

 

[roguly]

Your coils are un-even diameter and have un-even gaps between them. Also looks like you mightve used to much wick and your choking the coils.

Thanks for the feedback guys. Originally I had them spread apart with a lot less wick and barely got any vapor. Figured double up the coil and wick but still no dice. My carto tank is producing about 4 times the vapor on the same mech mod.

Would I be right guessing that it takes forever to heat up? There's a whole lot of coil there. Personally, I would try 3 strands of wick and use maybe 5 wraps as tight as you can get it. Check your resistance.

What is the coil resistance? I use micro coils in my IGO-L at around 1 ohm and get loads of vapor and flavor. 10 wraps of 27 gauge Kanthal on a 1/16" diameter eyeglass screwdriver (or a drill bit) and a cotton wick. Here's a video of super_X_drifter setting one up.

Also, there's a great thread on battery safety here. Keep in mind there are no built in safety features in mechanical mods, it's all up to you. Know the resistance of the coil, what amp draw that will produce and make sure your battery can handle it.

Yes. Answer this question first... What is the resistance?

 

[Muggs]

I think the resistance is 26.00 Ohms/Mtr. I got it in a kit but searched that type of wire. It htink it's Kanthal A1 Ribbon Heat Resistance Wire - 0.5mm x 0.1mm.

26 ohms? that is WAY too obscenely high. A coil should be around 2 ohms.....

 

[Muggs]

2nd try. Still barely any vapor.

 

[minimalsaint]

OK , I'll be the one to say it.
If you don't have the means to test your coils when you build them and are guessing the resistance, it's a bad idea and you should stop there. Get yourself a multimeter and wrap a coil that meters out to 2.0 ohms and go from there.
Not trying to be rude, but more out of concern.

I think what you are trying to say here is that the wire has a property of 26 ohms per meter. Is that right?

You should use a simple multi-meter which can be had for cheap and measure the resistance of the coils you have made.

 

[Muggs]

^^^Yeah. I'm going to measure over the weekend and thanks minimal.

soooooo no one else noticed the coil is not over the airflow?



ribbon needs to be wrapped close together as well, then put the coil on the other sides of the posts over the airflow tube

for the win!!!

LOL, I'm so used to air holes in top caps, it never even occurred to me . Good catch Thrasher!

 

[Nytelife]

Do not let the coil touch the airflow hole or the posts or you will get a short and risk catastrophic battery failure.

+1 . Try 3 or 4 wraps around 2 lengths of the 3mm silica and make sure it is centered over the inlet hole on the other side of the deck.

Also +1 on getting a multimeter to measure resistance. Keep it at or above 1 ohm or you really have to start considering the amp limit of your battery for safety. It will also help you detect short circuits.

Hard short, yes... Catastrophic battery failure, don't think so...
