That's the exact video that helped me start the whole rebuilding thing. I think Phil used to be a member here for a while as I also saw a video he posted here on ECF about rebuilding the vivi nova.
I used 32ga kanthal but 30ga. would work just as well. I also used 2mm silica X 3 which would create 6 wicks total,
three on either side. You may have to experiment a little, maybe get some 1,2 and 3mm silica or something to see which works best for the liquid you use.
You might find it easy, I know I didn't at first. I had to get my wife to help me after spending about 2 hours just making a mess of the whole thing. I look back on those days with fondness though, because it's often when you make a mess of something that you learn the most.
So wishing you the greatest of messes Discopotato - good luck.
