I posted this to Reddit last week but figured I would throw it here for better archival purposes. Here are instructions on how to rebuild a Vivi Nova with a cotton wick.
Hit The Jump for the full details and step by step instructions.
I recently was re-wicking my Vivi Novas with cotton wick and noticed that the flavor was really muted. I tried long variations and short variations. I just could not figure out what was going on with it. I was going to change to using silica and figured I’d give it one last go.
The cotton just seemed really thick so I decided to “de-braid” it. I figured this would make it far less dense and gives the juice a little more room to move. I did this tonight and I can honestly say that it has improved the flavor immensely from the braided wick. The flavor is remarkable!
This is the old version of the cotton wicks I was using. The flavor of my e-liquid was muted and something was just off. I believe the wick to be too dense.
Wrap your Kanthal wire around the wick and, with the sturdy object still in place, arrange the coil neatly and space it as best you can. I usually do around 5-7 coil “lines” to reach a desirable Ohm rating.
Replace center pin, trapping the other wire. At this point I place the whole unit straight up and down between my thumb and finger. I then grab the wires and turn them like you would a crank. They will snap neatly off.
This is an excellent vape and it only takes about 10 minutes to rebuild the wick. I find I spend the most time getting the coil lined up and spaced really well.
I use this cotton wick from Amazon. It’s $8 for 30 ft, but if you “de-braid” it you can double or triple that length.
As always, you should boil the cotton for 15 minutes and let it air dry completely. Also, the cotton needs to be wet, so no dry burning or you might set your house on fire.
