IGO-L tips

Try to avoid using a coil with long legs. If you are using a coil with long legs, consider over wrapping the coil with kinks at the legs to contain the current in the coil, not the legs. I believe the kinks increase the resistance enough to concentrate the current in the coil.

Thanks I'll try that too. I really want to do the longer legs so I can do the smaller diameter coil I like but have the coil next to the edge. So far this set up with 5 lengths of 2mm silica for a large coil is working really well, 4 wraps of 30 ga Nichrome 80 for 1.2 ohm, but I prefer less silica since I'm switching juices all the time. For now happy to be getting as good a vape as with my IGO-S, hitting awesome at 14 watts.

What? . . . . . . . . Serious? . . . . . . . . .Serious?

←←←←←you mean kinks like these? contain the current? . . . . . . Serious?

Yea, kinks like those.

Water is commonly used as an analogy to explain electricity. In this example, the "kink" is similar to folding over a water hose to stop the flow of water. Another example is putting your thumb on the end of the hose to spray a stream of water, your increasing the resistance by reducing the diameter of the hole.

Think of the coil as a series circuit, with increased resistance at the coil itself, and the legs having a lower resistance. The same amount of current will flow through the coil as it will in the legs. The higher resistance will utilize more of the voltage, and generate more power [ wattage ], which will concentrate the heat to the coil instead of the legs. I should have used the term wattage instead of current, the current remains constant in a series circuit.

Is that why, after all those kinks, my center coil is the dimmest in this picture

The center coil is most likely making better contact with the wick, partially transferring some of its heat energy to the wick [ "heat sink" ].

I recently read about this "heat sink effect" on Wikipedia, which states that "heat will be transferred from the higher temperature region to the lower temperature region".

Taking your sarcasm as the lack of curiosity for knowledge.

OK, ok, seriously. I don't have much wiki-knowledge, nor have I studied electricity: but I have built hundreds of coils, many of them creative, all of them ultimately successful. Some of the stuff you're saying doesn't translate to the reality I'm experiencing in practice. I put kinks in my coils for a lot of reasons; but those kinks never reflect the kind of effects you have suggested. Also, you originally suggested them as a means of solving a problem that doesn't exist. Long legs, in and of themselves, stay cool and don't pose a problem. They don't glow dry and they don't glow wet. they don't glow kinked and they don't glow straight. And, unless I'm standing on a folded over 50ft extension cord, running 120 volts, any change in resistance is negligable. That's all I meant to say with my little silliness. Peace.
