Coil Building Tips: How to build a vape Coil

Coil build

Coil building can be fun. Not only for you but also your pocket –you won’t need to buy new coils every time your coil burns out.

More importantly, you get to test your skills as you build by your hand. Coil building can be challenging and messy at first. But, with practice and patience, you’ll get the hang of it over time. Once, you get it right you’ll never look back.

The intent of this article is to bring you to the light. Wait! We are not preaching. All we meant is that, you’ll no longer crawl through the dark in matters regarding coil building. From building simple coils to the most complicated coils like claptons.

Let’s get started.

What you need to get started

You’ll need a variety of tools while out here to make coil builds. Here, we’ll just keep it simple without all the technical stuff. Most rebuildables these days come with coil building tools. You’ll be surprised to find that you already have most of the tools we’ll mention at your disposal.

Here are essential tools you’ll need:

  • Vape Wire

There are lots of resistance wires but Kanthal is the most commonly used. It easy to use and holds shape while wicking. Besides, a spool of A1 grade kanthal can make around 20-30 standard coils.

As you advance in coil building you can experiment with other wires like stainless steel, nichrome, nickel, and Titanium. Look here for more on the best types of wires for coil building. Trying out the different wires will give you more control over your vaping experiences such as better flavor and bigger clouds.

  • Cotton

For building coils, you’ll require organic cotton for wicking i.e. undyed, unbleached cotton that’s sterile and safe for use.

Japanese Organic cotton is the most popular. It saturates quickly, gives good flavor and is inexpensive. Note, there are also other wicking materials like silica wick, cellucotton, rayon fiber, Ekowool wick, and Stainless mesh.

  • Tweezers

Tweezers help you to pinch your coil and tighten your coil into place. A pair of ceramics tweezers are best suited for the job. They are strong and provide accuracy while pushing your cotton wick into place.

That way while you’re pulsing, the coil is hot and fragile. You need to take utmost care while pinching.  Ceramic tweezers will help you do just that.

  • Scissors

Scissors allow you to trim the wicking cotton to the right size and shape. You should have a dedicated pair that is reserved only for working on your vape cotton. As a result, your wick will always be clean and free from dirt.

  • Diagonal cutters

Another essential tool to save you from the hassle.

 With diagonal cutters, you can trim your coil wire without much fiddling. Sometimes cutters come along with your building kit. Thin wires cutters are more accurate as they cut close in small spaces.

  • Coil Jig

Coil jigs are used to wrap the wire around it to make coils. You can use it to position the coil while you push and pull the coil to sit perfectly in place.

 If the coil jig is unavailable, you can use a screwdriver in its place. Wrap the coil around it and use it to tighten the post on your RBA.On the flip side, it’s not as accurate as the coil jig. It might give you trouble especially when making closely knitted coils.

Most advanced coil builders tend to use the drill bit to wrap narrower and thicker coils. Then, use a screwdriver to tighten the post screws.

  • Ohm reader

Why do you need an ohm reader?

An ohm reader helps you to measure the resistance of your wire. You can easily get one from the vape shop. Or you can get one of the mods out there which detects resistance.

Now, you already have everything you need for coil building. Let’s start building.

How To Build a Vape Coil For RDA

Step 1 Cut the kanthal wire at a desirable length often 3 inches. But for beginners, who need a little extra wire to hold onto, 4-5 inches is the ideal length.

  Caution: The wire is springy at first and may uncoil on you. You can avoid this by heating the kanthal wire to oxidize it.

Step 2 Hold the end of the wire nearest to the screwdriver’s head firmly with your thumb. Wrap the wire around the 3mm screwdriver 8 times. Avoid overlapping and gaps in the coil while you try to keep them as close as possible.

Once you’ve achieved your targeted 8 wraps, you can hold one lead firmly with your fingers.  Then at the same time pull the other lead with your tweezers or pliers. This is to remove any slack your coil might have.

WARNING: Do not remove the coil from the screwdriver at this stage.

Step 3 Loosen the post screw of your RDA. Take the coil (still wrapped around your screwdriver) and thread one lead on the positive hole and the other on the negative hole. Try to position the coil central to the RDA while the screwdriver is still on. Tighten post hole and set screws to allow you to safely remove the screwdriver. Then, snip the leads as close to the post as possible.

Step 4 Plug the RDA into the ohm reader to test your coil for shorts. It should measure close to 1.2 ohms or have a slight variance of 0.2 ohms. If your coil resistance is 0.2 ohms more the target resistance, there’s a problem to be fixed. Mostly it’s about positioning –check your coils are well positioned and don’t touch the deck or the posts. Also, be sure that your atomizer is screwed completely into the ohms reader.

Step 5 Heat and pinch the coils together.  Repeat this process until the coil glows evenly from the center to the outer wraps. Don’t touch the coil with the tweezers while firing unless they’re ceramic.

Step 6 Wick your coil. Cut two pieces of cotton, twist their ends to fit through the coil and thread them through the coils. Once the cotton is threaded, trim the sides of the cotton sticking out. Tuck the cotton ends to the coils properly to sit on the deck of your RDA.

Step 7 Check coil resistance again after wicking. It’s likely the coils were pushed or moved a bit while wicking.  Don’t build lower than your battery can handle.

Step 8 Drip delicious e-juice into the wick. Attach RDA into the mod and put the cap back on and vape. It’s that simple.

To build dual coils, simply build two identical coils instead of one. Similarly, while firing the coils should glow evenly.

 What coils are you going to build?


Types of Coils

  • Single and dual coils
  • Macro and Micro coils
  • Twisted and Parallel coils

Single and Dual Coils

Most coils have not one but two coils hence the name dual coils. That one extra coil is what sets it apart from the single coil.

Unfortunately, not all atomizers allow dual coils. To identify a dual coil atomizer, check for the airflow at the positive and negative posts of the atomizer. If the airflow is hitting the post from both sides, then you’re using a dual coil atomizer.

More importantly, in dual coils, both coils have to be identical in shape and size to heat up properly. That means they’ll require double the energy of a single coil.

The resistance of a dual-coil should be exactly half that of each coil. Take for instance you’re using two 0.4 ohms coils, the resistance of your coil build will be 0.2 ohms. If one coil is removed, resistance shoots back to 0.4 ohms.

Macro and Micro coils

The diameter of the coil is the major difference between macro and micro coils. Let’s break that down further.

Macro coils –have inner diameters of 2.5mm and above

Micro coils –refers to coils whose inner diameters range between 1mm and 2mm

As you know, the diameter of the coil plays a big role in its resistance. The bigger the diameter, the higher the resistance. If you’re new to coil building and still unsure, the 26-28 gauge kanthal wire is a great place to start.

Twisted Vs Parallel Coils

Generally, the idea behind a parallel coil build is folding your vape wire in half. For example, you can fold your Kanthal wire in half. Once it’s folded, you’ll have two bits of the wire running side by side and parallel to each other.

A parallel coil offers a significant increase in vapor and flavor production. Plus, it’s incredibly easy to build once you get the hang of it. You’ll simply wrap your folded wire around a coil jig the same way you would a single coil.

Twisted coils are almost similar to parallel coils except that they are twisted. Simply, the folded wire is twisted to form one strand of vape wire. To do that quickly, you’ll need a power drill.

Well, it’s still debatable but there is no much difference in vapor and flavor production between twisted and parallel coils. Some vapers will prefer twisted coil to parallel only due to personal preference.


Clapton coils were originally conceived by E-cigarette forum member, mrdeec3 while watching his friend play guitar. He created it by wrapping a 32 gauge Kanthal around a 24 gauge kanthal using an electric drill. He then named it clapton after popular guitarist Eric Clapton.

Claptons have a slower ramp-up time than normal builds but are more popular for longevity, increased vapor production and superior flavor. This is as a result of their larger surface area and their tendency to act as wicks. E-juice may sometimes settle in the pockets running around the coils.

Claptons are a bit difficult to build but attainable with practice and proper tools. If you’re starting, we suggest you wait until you’ve more coil building experience.


So there you’ve have it, you can now build your coils. Hopefully, as you get better at coil building you’ll build more advanced coils like arched claptons and dragon skin builds.

However, it’s important to know the limits of your device, hardware, and batteries while building. Never build coils without an ohm reader.
