So, I had to go up a learning curve to efficiently rebuild KISS cartridges. Once I stopped trying to use the titanium wire, the process became ridiculously easy. The cost of getting proficient at rebuilding KISS cartridges included destroying my first Persei (replaced by up-tech) and buying multiple rebuild kits. Until I bought a crimp tool I destroyed most of the tiny, crimp, sleeve connectors (10 per rebuild kit). So I have about 18 ceramic wicks, many insulators (I can reuse them) and a spools of titanium wire that I may not get around to using. Can anyone recommend a place to get more tiny, crimp sleeves? I don't believe that W9/uptech hs these for sale on the site. I imagine I could find them after a couple days of searching the net, but I'm trying to cut down search time. Thanks.
