I started thinking about this when I purchased a couple of pre-made coils for my vivi nova tank from Avid vapers.
When they arrived the first thing I thought was how did they get such PERFECT COILS? Nice tight wraps they were nice and close together and uniform. No matter how hard I tried I could not make my handmade coils look that good.
Every video I watched would tell you to straighten out a paper clip. Lay the wick on the paper clip and wrap the coil. The problem with that for me was that the wick would never stay put. The wick would start out say on top of the paper clip but as soon as I would make the first wrap the wick would slip off to the side or to the bottom and the coils would be wide and uneven. So I thought how easy it would be if I could wrap the wire first and then put the wick in after the fact.
Enter my jeweler's screwdriver set. I took out the 2mm screwdriver. Took a piece of wire and started wrapping the wire around the shaft of the screwdriver. After doing about 8 wraps I slid the wire off the shaft of the screwdriver. And there it was a nice perfect coil with all evenly spaced wraps. Now all I had to do was get the wick inside the coil.
My first attempt was to dip the end of the wick in some water and try to twist it into a nice sharp point. Like you would do to thread when trying to thread a needle. Well that failed. No matter how wet I got the wick it simply would not stay twisted into a nice sharp point. So I thought what else I could do. About that time I spotted a candle sitting on the dining room table. So I lit the candle and then dipped the end of the wick into the liquid wax that had pooled around the burning wick.
I pulled out the wick and quickly twisted the end of the wick with the wax on it between my fingers and rolled it into a nice point and then dipped that into a glass of water to cool the wax. After the cooling process I gently formed the end of the wick into a nice sharp point as pictured here
After this was done it was a piece of cake to thread the wick right through the coil. Just like you were threading a needle. And there I had it. A perfect coil and wick.
When I initially cut the wick I intentionally cut it about 1/4 inch longer than I wanted the finished product. This would allow me to cut off the end of the wick I had coated in candle wax, as that end probably would not wick with the wax on it.
And for this experiment I used the 1mm wicking rope. The nice thing about this method is if you want the coils farther apart to cover more surface area it's just a matter of holding the coil by both ends and gently pulling the coils apart. If you want them closer together you can hold the coil between your thumb and forefinger and gently squeeze the coil together.
I hope this find will encourage all who struggle with making a nice coil to give this method a try.
