Why no hot legs when using cotton or yarn in vivi nova?

[JuniorNA]

Hey all. I tried a few times to use SS mesh on my vivi and learned quickly that I need to double up the legs or use Nr wire since the legs got hot due to the distance to posts.

What I learned is that when using silica /cotton/yarn ?? There are no hot legs ?

Does this have to do with the SS wick conducting electricity which causes the hot leg? Because I'll build the same coil with cotton and with SS and I get hot legs with mesh but it's fine with cotton ?

It works fine but I'm looking to see why it works ? Or am I crazy and will we still get hot legs when using cotton and I just don't see it ?

I could be wrong but I will guess that since the cotton retains more liquid the legs won't heat up as much because the constant supply of liquid allows a freer flow of electrons though the circuit.

im thinking the same thing. I also think that since the cotton is a non-conductor it allows the wraps to heat up and not the legs, where SS mesh is a conductor ? But the mess is oxidized for that reason, so that electricity does not pass through it, so it's still interesting that hot legs come up with SS mesh, but not with cotton

Maybe the build up of residue on the SS mesh is acting as an added resistor thus impeding the electron flow and causing the legs to heat up as well. I like brain-storming.

makes sense MaDuece - but then our theory would be void if we do in fact get hot legs when rebuilding coils with silica or cotton. Have you or anyone ever gotten hot legs when building with anything but SS mesh?
