Tobh Atty Atomizer Failed Building Coils

[BigFatClouds]

Hi guys!
This is my first post on ECF, and I'm glad to be here.
I just started on RDA and RTA, and I'm still learning.

I have a Tobh Atth Atomizer, kayfun Lite, Turtleship V2 mod with LG DBHE21865 Battery, and Sony US1865OVTC4 Battery. And a local Vape shop told me 26 gauge Kanthal is the only one that I need.

I was looking for some good builds on my Tobh and I saw Rip Trippers build of Nano Dragon Coil. He uses a 20 gauge blunt syringe needle and 28 gauge Kanthal. But the closest that I have is 1mm precision screwdriver and 26 gauge Kanthal.

I did 15 wraps on 1mm screwdriver, instead of his 12 wraps for higher resistance to compensate the bigger Kanthal. I got it at about 0.5 ohm. However when I fire it up, it took a LONG time for it to glow orange, inside out. And after I wicked it (organic-cotton), there was practically near to none vapor production. I'm using a fresh charged battery.

When the shops build it for me, it worked perfectly fine, it was when I pull out the coils and rebuild them myself then it stopped working.

Same thing happen with my kayfun, I copied Rip Tripper's chimney kayfun build, it also took really long to light up. By long, I mean i have to hold the battery for about 3-4 seconds until i start seeing orange. This is also with the freshly charged battery. i was wondering if im doing anything wrong. of if my battery is busted (i had them for 2-3 months. If im using too much cotton, or etc.

Thanks in advance!

Too many wraps on too small of a mandrel with too big of wire. 28 gauge works much better for Kayfuns.

26 is good for a tobh but you need a bigger mandrel. 15 wraps with 26 is going to take forever to heat up

If all you have is 26 ga., I would suggest 7 TIGHT wraps on a 1/8" drill bit. This should give you about 0.4 Ω build with dual coils. Forget those tiny ID coils, pathetic waste of wire IMHO. On a kayfun, 28 ga. is as low as I would go.

Last resort (I know you'd want to do it yourself) but RBA RDA Coils 10 Pre Built Coils 22 28g Kanthal 0 3 1 4 Ohm US Seller | eBay

Like he said , way too many wraps. I use 4 to 10 wraps on screwdrivers ( Stanley jewlers set) from 1.4,2 or 3 mm in size it just depends on what I am trying to do. Now caution ALWAYS check the ohms BEFORE use. And a regular meter will work. I didn't have one of the atty ohm checkers at first. Wife is tight with our money. But always check it before trying it. Then you know if it is right before trying to fire it or time to fix it like wrap another round first and a regular meter let's you check before cutting the wire
So vape on and be safe out there

The nano coils Rip does are a bit more advanced. What I will say, if you're going to follow someone's else build videos, you need to follow them EXACTLY as they do it. The specs are built exactly to work well with they use. The nano/nano dragon builds are meant to be used with 28 ga Kanthal, not 26, not 24, not even 30. That's why it's taking so long to ramp up.

As mentioned above, I would just do a simple macro coil - 6/5 wraps with 26 ga kanthal, dual coil on the tobh will put you right around 0.35 ohms, will heat up fast, and will be good.

The Kayfun should be used with simple setups. Do a micro or macro coil with 28 ga Kanthal.

Tyhanks capt I will try that when my TOBH arrives sounds like a good build but 28 guage I have but will ohm it for figuring the dual coil output

Rule of thumb for Kanthal wire is the larger or lower number the wire is the fewer coils you need. As for the TOBH ATTY, I stick with 28 gauge. You can do all types of wicked stuff with 28 or higher gauge that you can't with 26 and lower and you get a nice good cloud out of it. Like was mentioned before the more coils the longer it takes to heat up and also you have to make sure your coils are tight together. For a smaller item find a large paperclip and do your wraps on that. I always keep a small and large paperclip in my vaping kit for when I build and for cleaning and scraping but you need to be careful with the latter.

The thing about nano dragons, is that they have to be just the right length in proportion to their width. The reason it's taking so long to heat up is that with 15 wraps, the mass of metal that it needs to heat up is so large, that just touching that to eliquid, and it's no longer able to produce enough heat to compensate. I would recommend going 5-6 wraps around that 1mm bit, making sure that as you wick it, cotton is everywhere underneath and to the sides of the coil, but not inside, and certainly not on top of the coil. An internal diameter of 1mm, in relation to the height of the coil (roughly 2-3mm) will help with the "dragon" in "dragon coil" work properly. A coil too long, and the vapor being produced inside the coil gets cooked for way too long as it exits the coil, and the whole thing fails to function properly. A coil too short, and it just becomes... a regular coil.

Good luck with those coils, dragons are particularly hard to get right, as your wicking technique now has a lot less room for error, and your coil has to be perfect, or else nasty meltdowns and burning cotton happen, neither of which are fun.

If you need help on how to get dragons to work well, I can try make a pictorial or something. I've been doing them a long time.

Yeah, 6-7 wraps of 26g around a 1.5mm screwdriver is what I use every time on my tobh atty. As long as you get the coils nice and positioned and wicked well, it should hit like a dream.

Well if you don't mind making one, I'd be interested in seeing it! Always exciting to see how another vaper does something.

Thank You!

Are you using 26g kanthal as well for this?
Regardless, it would be great if you can pictorial. ^_^ (Thanks in advance, if you are going to do that )

PS: I just purchased 100' of 28g kanthal. While waiting for it in the mail, I want to figure out what I can do with my 100' 26g kanthal. I feel like I'm going to use my 28g more once I get it, and my 26g would be wasted.... Since it seems like none of my build needs 26g. ...

I just build a 5/6 wrap on a 3mm screwdriver, and to me, its still seem like slow to heat up the first time. I've linked a video below. But vapor production have improved, but that was because I switched to max VG. But still low for max vg.

The nano dragon style of wicking right?

I'm working on the pictorial. I just need to get my hands on thinner kanthal before I do this. I promise it'll be here soon (I'll edit it into this post box).
for the time being, this is a picture of my current build on my Tobh. It's all kinds of extreme

 

[amtseung]

It's done! Be warned, this is going to be very, very long.

To start off, here's all the tools. Typical stuff really: pliers, clippers, wire, cotton, tidbits.


Now we begin. I'm using 28g that my friend gave me. I cut about 3 inches of wire, as that's plenty longer than we'll need for this.


I wrap these 5 times each around a paper clip, like so.


and so we end up with 2. Look at how small they are :3


We feed the coils in and position them as close to the holes as possible. As you tighten the screws down, the coils will tilt up. This actually helps make the next few steps easier.

 

[amtseung]

Now it's squeeze'n'pinch time! Now you're glad you gave yourself that extra room.


With that complete, I went off to wash my hands. Clean hands on clean cotton means less funky taste. I don't want to vaping my own secretions.

Now for the part that sets dragons apart from all other coils: wicking. Take your cotton ball and unravel it. It should look like this.


Cut a chunk off, roughly an inch or so, so you have two rough squares of fluffiness.

Then take them and kinda fold them up. This is how I do it, others tell me it's the worst thing on the planet. Whatever floats your boat.


The idea is to get enough cotton under the coils, and a regular fluffy patch doesn't cut it. You'll see why soon.


Now you take those coils, still folded up, and press them down into the cotton. However odd this sounds, it works. As you push the coil down into your cotton bed, the cotton will end up forming around the coil as well, giving you a maximum wick to coil surface area for a dragon.


All that's left is to juice that up real good, being careful not to overdrip. If you overdrip, it'll splatter instead of vapourise. If you have massive air slots cut out of your cap like me, close off a little. Too much airflow drowns the coil in air, without enough pressure to pull vapour off the coil. Balance is key, and in this one case, velocity trumps sheer air volume. The amount of cotton becomes a fine balancing game as well. Too much cotton, and you get dry burns all the time because the cotton sandwiched underneath the coil is too dense and is unable to wick. Too soft, and your coil constantly floods, resulting in splatter instead of vapor.

When this works, it's beautiful, but it's surprisingly hard to make it work properly.

May the hate begin.

I use about 8-10 with my 28 gauge and a large paperclip. Can be hell to wick but oh the hit is worth it

 

[Elf31]

Tyhanks capt I will try that when my TOBH arrives sounds like a good build but 28 guage I have but will ohm it for figuring the dual coil output

Well I got the TOBH in and found out that since Im intending on using it on a MVP that dual sub ohm (0.53) coils dont want to work on it the MVP dont have the wattage to burn them very well. But have no fears I then rebuilt it with dual coils to ohms of 1.2 and it works awesome and with my 100% VG juices tons of flavored Vapor. oh and 24 guage is the kanthal I have so the coils are 9 wraps each on a 2mm screwdriver.and Vape ON!!
PS I did burn of the juice I usd on the TOBH on a mech mod I have and it worked fantastic so coils were fine just the resistance too low for the MVP

 

[danmac]

I use 28g and wrap it around a small screwdriver which was supplied to replace an iPhone screen. 8 wraps tops. Killer clouds! I'm not a fan of micro coils. I struggle to get the cotton through and when you do its so tight that it prevents decent wicking. Currently at .42ohms with this set up and it holds plenty of juice.

 

[Nightshard]

Since you just started and still learning as you say, how about standard single or dual micro coil.
