If you don't have a resistance meter, I would highly recommend you purchase one as it makes building so much easier.
(Note this is not a guide on building a microcoil!)
Take three 9 inch lengths of 0.2mm Kanthal and form an L-shape bend in one end of the wires. Grip this in the chuck of a drill. Carefully line up the wires so they are equal and grip the other end firmly with a set of pliers. Slowly start twisting the wires using the drill until the Kanthal has formed a nice even twist along its length.
Once its completed the wire will be very straight and have the appearance of rope. It the Kanthal snaps you have gone to far, you may need to repeat this several times until you get it right, you will soon get a feel for when the wire is ready.
Give the completed twisted wire a good rinse under hot water, then heat it to cherry red using a blowtorch or gas stove.
When you make a coil for a Kayfun, you need both legs to come out on the bottom of the coil, so you actually add another half a turn to your completed coil.
Make 7 wraps of this wire around a 2mm drill bit, and pinch it tight. Remove it from the drill bit and grip it with some strong tweezers and heat it again to cherry red using a blowtorch or gas stove. Make sure you hold it tight until it has cooled.
Slide the coil back onto the drill bit, and install it onto the build deck as shown. Note the 45 degree angle of the coil. Some builds require the coil to be parallel to the juice channels, but this coil performs best angled like this. You want the coil to be lifted about 1 - 2 mm above the airhole. Any higher than this and you will loose flavour. Make sure the negative leg doesn't touch the positive post!
This should come out to around 1.2 ohms. You can now install the base onto a mod and pulse the coil and tighten it further using tweezers as normal to make sure the coil heats evenly from the center.
Once you are happy with the coil, pull a nice fluffy organic cotton wick through the coil as shown.
Cut the tail of the wick off level with the outside edge of the base, and juice it up. Pull the tails back down and around as shown in this picture.
The wick should touch the deck above the juice channels, and be touching the vertical part of the positive and negative posts.
If you are using a particularly thick juice, pull the wick slightly away from the juice channels, but make sure it still touches the deck. For a thin juice you can cover the juice channels.
Carefully screw the bottom chimney section onto the base, making sure you haven't disturbed the wick.
Now add a little bit more juice to the wick and test fire. If you have done everything correctly you should get a lovely cloud of vape.
Screw the top section of the chimney on, install the tank section and the top cap (don't forget the o-ring in the top cap!). When you look through the top of the top cap, you should be able to see the chimney inside the o-ring.
Fill the KFL and enjoy!
