Today I want to mention that there are certain risks associated with short circuits in any electrical device as such please follow the steps in this guide to ensure you are building coils and vaping safely. If you do not have an ohms reader please do not attempt to build your own coils Now that you have all the supplies you need, before you get started wrapping coils you will want to figure out how many wraps your coil will need to have to reach the desired resistance.

Oxidize the Wire

First you will want to cut a piece of your kanthal resistance wire. Although 3 inches is likely enough it is often easier for beginners to have a little extra to hold onto so I recommend cutting a 4-5 inch piece of wire. You will then want to hold the end of your wire with your tweezers, pliers, forceps, etc. Light your torch and carefully heat the kanthal wire at one end until it glows orange then slowly move the torch down the entire piece of wire. Give your wire a moment to cool then grab the other end of the wire and repeat. Oxidizing the wire will make it less “springy” and easier to work with.

Wrapping Your Coil

You will need your tweezers, small blue screwdriver and your wire for this part. You want your wire to be on top of the screwdriver close to it’s handle. Hold the end of the wire nearest the screwdriver firmly with your thumb. You then will start wrapping your wire around the screwdriver until you have reached our target of 8 wraps. Do your best to keep the coils as close to one another as possible without any overlapping. It is important to try to keep the wire tight through the process to eliminate as much slack as possible. Once you have made your 8 wraps both leads should be facing the same direction. Double check your number of wraps by counting them on the side of the coil that is opposite of the leads. Once you are sure your coils has 8 wraps you can hold one lead firmly with your fingers and pull on the other lead with your tweezers or pliers then repeat with the other lead. This is to remove any extra slack your coil might have.

Wrapping Your Coil Using a Kuro Coiler

We will use the 2mm Kuro Coiler here. First insert wire into the hole 1 on the side of the handle leaving approximately 1/2” of wire sticking out from the hole in the handle. Hold the end of the wire against the handle so it cannot slide back out. Pull the loose end of your wire around the shaft. Place the top winding piece on to the shaft with the pin towards the handle. Turn the top winding piece slowly so it catches the wire and starts wrapping. Be gentle. Excessive pressure will cause the wire to wrap over itself. Once you have 8 wraps remove the top winding piece and straighten the wire that sticks through the hole in the handle. Adjust or straighten the leads as needed then remove the coil from Kuro Coiler’s shaft and slide it on to your small blue screwdriver for installation.

Installing Your Coil

Next we will want to take the build deck of your RDA and loosen the post screws most of the way. We do not suggest removing the screws completely because they are easy to lose and hard to put back in when your hands are already full. You will then take your coil (still on the screwdriver) and place one lead in your positive post hole and the other in your negative post. Using the screwdriver currently inside your coil try to position the coil towards the center of your RDA. Once you have it roughly positioned you can tighten your post screws. Be careful not to over tighten or you might cut the wire inside the post and have to make a new coil. Once your coil is mounted securely trim the leads as close to the posts as possible. Stat stuned to see the next chapter, you will have more information to know how to build colis.
