Myvapesite: Your bestE-cigarette shop
Building coils helps us, To save money, as it is much cheaper than purchasing pre-made coil heads. It's also a hobby, that is fun and that we are not only proud of, but we can also enjoy the fruits of their labor. However, it may be a little difficult for beginners. You want to build your own e-cigarette coils, but don't know, where to start? No problem. Here I will try, To give you some of that, what you need to know, to build a simple coil for your RDA. For the sake of beginners, I will only provide an example of a 1.2 ohm microcoil, which I have been using for a long time, as it is easy to build from scratch.
The materials needed to make the coils.
1. Ohm Reader
2.resistance wire: Kanthal or Nichrome (You can use different sizes of wire, if you decide, Build your own coil. You can choose between 22 g, 24 g, 26 g, 28 g, 30 g, 32 g and 34 g Select wire. The “g” stands for gauge. All these wires are available in Kanthal and other wire types, that are suitable for vaping, but for this article I will just 28 g Use Kanthal.)
3. Winding calculator (by adjusting variables such as wire size (28 g), Coil type (individually), Zielwiderstand (1,2 Ohm), Inner coil diameter (2 mm) and leg length (4 mm) this calculator tells you, how many turns need to be wound. Our 1,2 Ohm single coil required 8 convolutions.)
4. 2 mm small screwdriver
5. Additional small screwdriver for your RDA screws.
6. tweezers (preferably ceramic tips, to grab your coils while pulsing)
7. Small wire cutters or nail clippers
8. Scissors for trimming your cotton
9. Organic cotton
10. E-cigarette juice
Wind your coil.
Now, since you have all the supplies you need, it's time, to wind your coils. For this part you will need a small 2mm screwdriver and a resistance wire.
You should place the wire on the screwdriver near its handle and hold the end with your thumb. Then start, wrap the wire around the screwdriver, until you reach your goal 8 achieve revolutions. Do your best, to keep the packages as close together as possible without overlapping. After 8 Turns, the two terminals of the coil should point in the same direction.
Install your coil.
Next, you should pick up the RDA's build platform and loosen the post screws. You should place one lead of the coil in the positive post hole and the other in the negative post. You can then tighten the column screws. But don't overtighten or the wires in the post could be cut. After installing the coil, cut the wires as close to the post as possible.
Test your coils for shorts.
After making sure, that your coils are installed correctly, it's time, Test your coils for short circuits. You need to take the RDA and screw it onto the ohm reader and turn it on, to ensure, that the new coil is not short-circuited. The resistance shown by your ohm reader should be close to the target resistance of 1,2 Ohm lie. Unless, check your RDA's post screws, to ensure, that they sit tight, or check your atomizer, to ensure, that it is fully screwed into the ohm reader.
Test your coils.
If your coils are not shorted, you can move on to the next stop: Put your RDA back on your mod. You can then briefly trigger your mod, until the coil starts to glow. If your coil starts to glow, squeeze them lightly with tweezers. Repeat this process a few times, until your coils glow evenly from the center outwards.
Wick your coil.
You need a piece of organic cotton, that fits into your spiral, and leave half an inch of space on each side. It helps, moisten and twist the end of the wick. If it doesn't go through easily, this means, that your wick uses too much cotton.
On the other hand, if your wick slides loosely in the coil, this means, that there is not enough cotton. Once your wicks are through the coil, remove the wicks from each side and trim them.
