So I think I'm about ready to make my own coils just has a couple questions for you guys. I've read the charts that have been posted on the forums and they have been very helpful. Now I'm looking to build a sleeper build to come out to about .3ohms. I was going to purchase 22 or 24 g kanthal wire, and I've got a stanley 2mm screwdriver (what RIPTRIPPERS had recommended), well he actually recommended one that came out to a 5/64 drill bit but this was the closest equivalent stanley had so i'm guessing this is what he was using as well. So I was going to build the dual coil build with one wire per the sleeper build requests. I was planning on wrapping it about 9 times on each side to get the resistance to around there. Does everything sound about right here guys? Any help is appreciated fellas!
Okay guys, Looking to get the tools and make my first build!

Looks about right, using 24g. A great tool I use to determine what I need to build is

There are easier coils to build as your first. The sleeper is far too fiddly, in my view, for a beginner. I'm also of the opinion that 0.3Ω is too low for a beginner.
I'd recommend building closer to an ohm and at the very minimum above 0.5Ω. Start with 26 or 28 AWG wire and you can pick up a set of precision screwdrivers for pennies at a hardware store.
As a previous poster has said, steam-engine is a great place to model your builds.
Make sure you have an ohm meter to check your builds on BEFORE you fire them on a device. The last thing you want is a short.

This is VERY helpful man thanks so much! Now theres one thing i'm confused about.. it looks like i'd be better off using 25 g kanthal so I could do 9 wraps on each side as opposed to 10.. Now I thought the lower the gauge of kanthal like I thought using 24 gauge would mean less wraps but from what I'm getting out of this it's the exact opposite. This is saying if I used a 28 gauge kanthal I could do 5 wraps on each coil where as I was thinking the exact opposite.. So the higher gauge you go up in kanthal wire the less wraps you'll have to do and the quicker you'll reach to .3 ohms where I'm aiming. Is this corrrect?
Makes sense to me now! For some reason I was under the impression that the lower the gauge would result in less wraps to make a sub ohm <.5ohms around .3ohms
Larger wires=smaller gauge numbers. The bigger the wire, the lower the resistance. The more wraps you add, the higher the resistance.
+1 on starting off with 28G Kanthal. It's easy to work with and safer. You should probably build a single coil first and make sure it works right. Try 6 wraps, single coil, 3mm ID. Or about 8 wraps on that 2mm screwdriver. It's about 1 ohm and will fire at 15W. It's not gonna "chuck klowdz bro...", but it's a great start to get your feet wet. After that, try adding a 2nd identical coil. That will bring the resistance down to about .5 ohms. Up the wattage a little and it will chuck a medium sized cloud. When you are comfortable with that dual build, then you can play with other wire gauges and types.

+2 for starting with 28g kanthal, and also with a plain contact macrocoil for your first. No need to get fancy until you're comfortable. It's easy to feel like you have a total handle on it just by watching videos, and it's entirely possible to learn very quickly, but do something simple so you can feel what it's like to work with the wire and small tools. Those with backgrounds in jewelry, electronics, etc. might have an easier time but there's no need to get fancy right off the bat. Your second coil can be a 22g sleeper, if that's what you really want.
ITA 6 wrap on 3mm or 8 on 2mm with 28g kanthal are good starter builds. I like 3mm wraps for their ease of wicking.
And yeah, what are you building on?

Without repeating the (solid advice) Big Me and Hans gave you about starting with #26 or #28. There's just a natural progression to it and you've been handed the most well balanced starting point.
A few things will make life way easier when rebuilding.
- coilmaster V3 (it lets you wrap both directions...which can be a plus)
- ceramic tweezers (lets you squeeze the coil while firing)
- a good pair of mini wire cutters
You can get by without any of it, but it makes rebuilding effortless by comparison to the old way of torching the wire, pulsing the coils and trying to squeeze them before they cool down repeatedly, etc.

this is an odd analogy.... think of the gauge as the number of wires layed length wise side by side to equal an inch worth...
e.g. it takes 22 wires of 22 ga to be an inch in width, 36 wires of 36 gauge to equal an inch worth.. this isnt a true measure but an idea how it can be thought of...
the thinner the wire the more resistance it has thus less length is needed to get to a specific ohm rating...

Best advice so far.
No need to jump right into exotic builds at the start; leave those to the hobbyists and enthusiasts. I've been building coils for over a year, tried the exotic builds, and to this day I prefer the simple coils over the fancy builds. K.I.S.S. (keep it simple, stupid)
IMHO, unless you just enjoy the hobby aspect of building exotic coils, you quickly reach a point of diminishing returns when you factor in the time and effort the exotic builds require. The You Tube celebrities need to keep coming up with exotic builds in order to get viewers to continue watching them. I seriously doubt that if in a blindfold test you'd be able to tell the difference between a simple coil and a sleeper or other exotic build.
No need to jump into super low ohm builds, either. Get comfortable building normal resistance coils first (1.0 ohm), measuring them on an ohm reader, insuring you understand how to use an Ohm's Law calculator, etc. Then try building lower to see if you really notice an improvement.

Baditude is exactly right. In my opinion, those exotic coils are time consuming, add a whole lot more metal to heat up and cool down. I tried out the double and triple twisted, tiger wire, sleeper coils, dual parallels, and at first I thought I was getting better vapor production and flavor, but it was short-lived. I find my simple dual touching coils, 2.5mm to be just as good and the coils last a whole lot longer. Start simple, and keep it simple!
