I got lucky with my first SS wick and coil, it was just stellar and a new plateau in vaping for me. Not so with subsequent efforts. In trying to dupicate this on a second coil I ran into resistance issues, with the ohms jumping around wildly on the tester, from seriously sub-ohm to well over 2.5 ohms. Just touching the coil head on the tester would make the number jump around all over the place.
I could check it once, getting one reading, take it out of the tester, put it back in, and get a totally different number. Very strange.
Apparently SS coils in Protank heads are very touchy things.
Well undaunted I pressed on until I got one made up that seemed stable in resistance, but then delivered a terribly harsh vape, and kept on doing that no matter how long I vaped on it. Bummer in the summer.
I'm thinking I have a hot spot on that coil or perhaps didn't correctly oxidize the mesh, or something I've yet to discover. It would seem that SS is a very different thing from silica, and a good deal trickier to get right.
I'm making my wicks with 400 mesh SS, a piece about 10mm x 35mm, oxidized with my pencil torch, and using 32 ga. Kanthal, 5/4 wrap and shooting for 1.8 ohms, or thereabouts.
Making coils in a Protank coil head is a bit tricky in the first place, you can only see the top of the coil, it's pretty small, and you can't really check resistance until it's installed. Then if it's wrong you have to start over and wrap the whole thing again.
My first SS wick and coil was fabulous, but after that I ran into issues and complications. Hints and suggestions welcome.
