Are the coil wire and wick material interchangeable in all of those rebuildables? I like that Mighty now or the IGO-S. Excellent pics and website navigation, BTW
Rebuildables can use anything you can put in them... there is no standard per se. Usually you purchase the size and type of wick you want and then select the gauge of wire and build it. Currently there are 3 main types of wick... silica, stainless steel and ceramic. The silica's come in various thickness's so you want to get the size your rebuildable can take...
Most RDA's ( ie rebuildable drippers ) can take any size so you get what you like the most. The tank style RBA's you'd select one that can fit and the fill the holes that go into the tank area. Most RBA's will use 2mm, 2.5mm or 3mm but each differs slightly.
The SS mesh is usually used in the RBA's but some RDA's can be setup with it if you know what you are doing. Originally, it was thought that for thicker juices you'd use a courser mesh. Later we've found that the finer ( higher number thread count per inch ) mesh's actually wick better due to how capillary action actually works. Silica still wicks quicker than SS mesh but it lasts longer.
Ceramics, at least the ones I've tried... aren't quite there yet but they do work ok and are very clean tasting. They are fragile and don't wick as much as the others.
For the resistance wire... Most are using kanthal over nichrome for a couple of reasons. The kanthal can take a higher temperature so it doesn't burn in two as easily. The other reason is that many get a metal taste with it, not everyone, but enough that it is an issue. When selecting a gauge of wire to use, most like a larger gauge ( which is a smaller number btw ) since it gives more surface area to vaporize a liquid from. The down side ( if there is one ) is that it means you need more wraps to get the resistance you are trying to achieve. Ribbon kanthal is also now becoming popular because it is a little bit easier to make a coil with and has a larger surface area to vaporise with. Like the larger gauge wires, the low resistance that a ribbon has means you again need more coils to get a higher resistance.
