Latest try. I'm using cotton yarn that I boiled to get the sizing out. I'm also trying a different NR wire.
Up till now I've been using .999 fine silver wire for the NR portion but, I saw Imeo mention nickel wire in a couple
threads. So, I got some of
this nickel wire. It's cheaper than the silver and I don't have to depend on finding a supplier on ebay. Sorry, I can't say whether it's available outside the US. It's stiffer than the silver but, not bad to work with and it's working great so far.
From a vaping experience, the cotton yarn is about the same as the roll cotton but, it's a lot easier to get consistent. So far, it's lasted longer than any of my cotton wicks.
