Coil Building 101
So, you want to start building your own coils? It makes vaping more fun! So many more choices in build styles, flavor productions, vapor productions, etc.! Building is my absolute favorite part of vaping! I will be taking you through step-by-step of how to build your basic coil for your RDA/RTA/ RDTA! (P.S. if you want to watch the video instead of reading this, click here)
  1. You will need all the materials necessary for building, You will need your wire, cotton, post to wrap your wire around, scissors, and ceramic tweezers (Shown Below). See our selection of tools and materials here.
    • In this picture demonstration, I will be using the tools included in the Coil Master, a wonderful kit if you want to make building as easy as possible!

  2. One you have all your materials, choose the post you want to wrap the coils around. I used a 3mm post in this particular demonstration, since it is the most common.
  3. Insert your wire through the coil jig and place the top on. Spin the top to easily wrap the wiring around the post to make your coil. (make sure you do not apply too much pressure, as this could cause problems while wrapping)

    • Something to think about when choosing wire is the gauge. The lower gauge wire (22g, 24g, 26g) is lower resistance wire, so you can use more wire without increasing the resistance of the coil. This is useful when making lower ohm builds! The more surface area, the more vapor produced.kuro-coilers-mod-kanthal-coil-maker
    • The number of wraps will also affect the resistance of the coil! You can either look up the gauge wire and wraps needed for a certain ohm, or just play with the builds to figure it out on your own!
  4. Once the coil is wrapped and ready to go, use the wire cutters to clip off any extra wire. (make sure you leave about an inch or so on each side so you can thread the coil into the deck)

  5. Once you have the coil in place, tighten the wire down. This can be different depending on the style deck. I am using a clamp style deck in this process, but there are multiple different deck types.

  6. After tightening the wire down, use the wire cutters to clip of the excess wire. Once this is done, make sure the coil is centered and straightened for proper firing and wicking.

  7. If you are using a regulated mod, which most new builders would, the mod will read the resistance (ohm) of the coil. This is where you can choose the wattage you want to run the device at. Refer to my Ohms and Wattage article for more information on this subject.
  8. Now that the coil is set into place, you have to fire your device to see if the coil heats up properly. It’s almost impossible to build a perfectly firing coil, so you will need your ceramic tweezers to spread or squeeze the coil until it all heats up evenly. You should also pay attention at this stage to making sure that your coils are STRAIGHT & CENTERED in the deck. If you don't do this it can lead to dry hits because your cotton is not wicking juice evenly from both sides of the coil. This is the trickiest part for beginners, as it can take some practice to get it perfect.

  9. When the coil(s) are heating up correctly, you are now ready for wicking. Take your cotton and fit it into your coil(s). Cut off any unneeded extra and tuck the cotton to the base of the deck. Depending on style, you may need to move cotton to sides or center for best airflow.
  10. If you are making dual coils, repeat all above steps!
  11. Time to make things juicy! Use your favorite flavor juice and soak all that cotton!
