A Beginner's Guide To Coil Building
30 Oct 2017
Once you have been vaping for a while, you might be keen to upgrade your vaping experience so that you can enjoy better customisation. If you are ready to move your vaping experience onto the next stage, you are probably interested into learning how to create your own kit and build coils yourself. Although it may seem difficult, the good news is that it is nowhere near as complicated as you might think, and if you follow this guide, you will be an expert in no time!
Why Build Your Own Coils?
Experienced vapers often swear by coil building, but what are the benefits? Firstly, you will be able to make savings on the cost of buying replacement pre-built coils; however, probably the best advantage is that you can create a unique build to suit your personal preferences and requirements for a totally customised vaping experience.
What Do You Need To Get Started?
There are a few essential items you will require to get starting with building your own coils:
- Resistance wire – the type you need depends on your vaping preferences. You will need Ni200 if you vape in wattage mode, Kanthal if you are a TC only vaper, or stainless steel if you like to vary between the two.
- Tweezers with a ceramic tip
- Wire cutters
- An Ohms reader
Before you start, the first thing you need is a grasp on the basics of Ohm's Law. You will also need to be aware of your battery specification as this is key to determining the required resistance for the coil and the number of wraps you will need to make. Use an online coil-wrapping calculator to make this calculation easier.
Wrapping the Wire
Cut 5” of wire using wire cutters. Start wrapping the cut length of wire carefully around the shank of the screwdriver and wrap tightly along its length until you have created the correct number of wraps. Keep them close to each other and adjust the extra wire to the end of the coil so it faces the same direction.
Install the Coil
Now the coil is built, you need to complete the installation process. Take the RDA out of the mod then loosen its posts until its holes are big enough for the coil's ends to fit through. Put one end of the coil into the negative post and one into the positive, keeping the coils' position as near to the centre of the RDA as you can. Tighten up to posts so that the coils are firmly held in place. Now, you can remove your screwdriver by sliding it carefully out of position.
Check the Ohms
This is a key step in the process of building a coil. You need to test the resistance of your coil before you attach your RDA into your mod for safety reasons. You will need an ohm meter to carry out this step. Check the resistance, and if it does not meet the reading you were expecting for the number of wraps you have made, you need to check the position of the coil to ensure it is not making contact with either the RDA's base or the posts. If it is, you can use the tweezers to adjust its position, then you can check the reading again. If it still does not give you the resistance reading you are looking for, you will just need to make a new coil with some more wire and try again.
Test Fire the Coil
If the coil has achieved the resistance reading you were expecting, you can go ahead and reattach the RDA to the mod. After it is securely fitted into position, you can fire for a few brief bursts, allowing the coil, to heat up until it starts to glow brightly. When it starts to glow, check the entire coil is showing an even glow. If it is not, and some spots are glowing more brightly than others are, you will need to use the tweezers to squeeze together the coils lightly. It may sound obvious, but make sure you are not firing the coil as you apply the tweezers! After you have removed the tweezers from the coil, test fire once more and continue repeating the process until the coils show an even glow which begins in the centre and moves outwards.
While there are many different materials which can be used for wicking, one of the most popular is organic cotton since it produces a good flavour and is very easy to place. If you are using cotton for your wick, cut a sufficient amount so that 0.5” is left on each side of your coil, after it has been threaded through. Twist the cotton before you thread it through your coil, as this will make it easier than simply pushing it directly through the centre. Avoid packing too much cotton inside – all you need is an adequate amount to create a snug fit, however do not use too little either, as otherwise it will burn too rapidly and this will produce an unpleasant taste. After you have threaded the wick through your coil, trim down the ends leaving just enough so that it gently touches the RDA's base, and bend down the extra cotton to the base while allowing a good airflow through your RDA for a much better hit on inhalation.
Just Before Dripping
Before you start to drip your favourite e-juice onto the coil, you will first need to check that your new coil has not accidentally been moved out of position during the process of wicking. If it appears to be out of position, use the tweezers to readjust it so that it sits steadily in your RDA and can fire consistently again. If necessary, tighten up the posts again, and then test it one last time with the ohms meter so you can have peace of mind that it is safe to use.
Now that you are all done, it is time to drip your e-liquid and enjoy the fresh coils that you have built with your own hands! Go chase that cloud!
