18MGFog Posted July 29, 2013 Share Posted July 29, 2013 I'd like to try either stainless steel mesh, or metal foam, as a wick. I have seen it done in videos, and it seems to work fine ... but I can't believe what I'm seeing. What prevents the coil from being short-circuited, from the first turn to the last turn, right across the metal wick? When voltage is applied, what actually happens in the coil and in the wick?

Rixter Posted July 29, 2013 Share Posted July 29, 2013 When you oxidize the stainless steel wick by torching it, it eliminates its conductivity. Uma 1 Link to comment Share on other sites More sharing options...

Not quite, if you put a meter on torched SS it still conducts. But current will always take the path of least resistance, in this case the coil..
