Theoretical build for a single coil aqua atomizer (I am new to RDA's)

[imb1610]

Pre info: I was recently informed(plus I liked the idea of saving battery and ejuice on a single coil) that my Zmax v5 is not the optimal build for a dual coil but due to the setup of the aqua I was trying to figure out how to get more surface area on my wick covered using a single coil this is my result please feel free to correct my math as I have not taken a physics class since high school. (I must add i do not have my aqua clone yet just bought it will be here within next week) I will be using 2mm cotton wick and 30awg kanthal)

So this is my first test build for my aqua atomizer once it arrives I wanted to know what you guys think and if you have any advice or corrections to my math

So I determined based on the sellers description of my 30awg kanthal wire (8.36 ohms per foot) (1ft = 304.8mm ) that there is (0.02742784215 ohms per mm)

I will be wrapping said wire around(9 times) two 3/32” drill bits (the circumference for the drill bit is 7.4809175064)
Because it will be wrapped around 2 drill bits (7.4809175064 * 18= 134.6565151145)

Then I added an extra 20mm for variable x and z to reach the terminals and an extra 30 mm for Y to connect the two sides together (134.6565151145 + (20*2) + 30= 204.6565151145)

Then I had to calculate human error (in making the loops etc.) so for this variable I used an arbitrary number of 50mm(204.6565151145 + 50 = 254.6565151145mm) 254.6565151145mm for the whole set up (which means the total resistance would be (254.6565151145* 0.0274278 = 6.9846734404) rounded to 7 ohms

I made a test run with some string and got results way off from the calculation at the end my string measured at 280mm which means the total resistance was 7.7(rounded)

With that being said before I continue to work and plan out this build I have to ask a few questions
#1 Is the build drawn(very poorly I might add) in paint effective/safe/possible??
#2 Is it risky to leave so much kanthal exposed without wick??
#3 Are my calculations on the money or far off in povertyville?
#4 to cut the ohms in half I did have a plan to make a twisted coil illustrated here: Twisted 28 Gauge Micro Coil - YouTube
Is there any reason why this is a bad idea?

Here is the poorly drawn blue print

Whoever told you dual coils aren't optimal on a zmax is and idiot. Your coil idea isn't going to work. There's so much wire that it'll take forever to heat up, you have an insanely long leg going over the airholes, and that coil won't hold its shape under continual use. This atty was designed for dual coils so why not just build what it's meant for?

My advice - buy an ohm meter. Save math for schools. The easiest way to figure out resistance is to get a quality ohm meter (20$) and experiment a little. With so many tiny numbers/measurements you risk getting your resistance off by a small amount. My ohm meter is accurate +/- .01, and reduces the amount of worry that I made a mistake measuring x,y and z. As for running a single coil in an Aqua you can try it.. but I would guess it'll flood. I build mine with microcoils and ekowool and it works great. Above one Ohm your battery should last all day.

@ scrappy i must apologize i grossly misquoted him he was referring to twisting my 30awg then running it dual coil let me just copy and paste his response

First of all don't twist your 30 gauge yet. You can easily drop the ohms too low for your mod. Second, that is 2mm cotton wick, and it will not fit through a micro coil at all unless you cut a small piece and fray it apart, which should actually work well. If you make a coil on a drill bit that is roughly the same size as your wick, but use the same process as making a micro coil, you will end up with a healthy, well fed mini coil. I would stick to single coils for now just because you have a zmax. You can try something like this as well. Aqua by UVO systems atomizer ,setup single coil silice3.0 MM,kanthal 0.20 - YouTube

@cantstopwontstop i have an ohm meter but my kanthal has not arrived yet lol so i cant really run an actual test using kanthal since its not here but i will try a dual coil i just liked the idea of saving battery and saving juice was just looking for a way to build it as a single coil

He's just saying that twisting will reduce your ohms by half and I think he's trying to say with twisted 30g you might have too many wraps for it to fit in the chamber of the aqua. The way he said it is a little confusing. My advice is to just do duals with your 30g. With a 18g needle you'll be in the neighborhood of 10 wraps to get to 1.2ohms which is just fine on a regulated device. Btw, if you do a single on the aqua it'll flood. Even blocking off the other juice channels with cotton will probably flood it. Just use it the way it's meant to be used before trying something off the wall.

Point taken your right guess im just getting a bit too excited might buy nimbus to try some crazy stuff on it ive seen Quad coils on youtube that look super cool thanks for your time though
two last question
is aqua known for flooding with cotton? or was that just with my proposed ....ty build?
and last should i still wrap my coils around a 3/32inch drill bit? i think it sounds appropriate for 2mm wick?

 

[scrappy]

The real aqua doesn't have any problems with leaking from what I've heard, but the clone has a couple reports of it. But that could also be people's inexperience with it. As for the nimbus, there are much better drippers out there. Something like the atomic or trident would be better for you because you can try different airhole sizes without having to drill it out.

I don't know what a 18g needle is as an imperial fraction, but that's the size you should be using. Forget about the 2mm wick. Use as little cotton as will slide into the coil without forcing it and you'll be OK. The cotton will swell a lot so you shouldn't have any problems with flooding from the juice channels.
