8-o

Hmmm, guess I need to scrap the plan where I hold it in my bare hands while I run the match under it!8-o

Not at all, because it is so thin, it dissipates the heat just about instantly. Heat one end from end to middle, switch ends and heat middle to end; haven't burnt my fingers yet ;).

Forgot all about having set up this calculator for work :facepalm: It's perfect for getting an idea of the length of your resistance wire, and with that, the resistance (ohms) of your coil. Unless you have a perfectly formed coil and exact measurements, this will be a ballpark figure; but should be a close ballpark :D

If you use this and have any issues, please let me know - this is provided with no guarantees of receiving correct or accurate information ;)

In one of the Kanthal .pdf files it said that Nichrome was mechanically stronger... but now I'm not finding it :confused:
I got the Kanthal because in the forum they said the Kanthal, being mechanically weaker, was easier to make tidy coils with.

I'm new to rba's. Got a Line V2 last week. I believe I have the wick preparation down. No I've been working on find the perfect coil. Tried 36awg Kanthal. Kind of flavorless unless I do a lot of wraps for a 4.0ohm coil. But that runs my battery down to fast. No I'm using 32awg Nichrome and I have just as many wraps but a lower resistance. GREAT flavor. I find the more surface area of the wick I cover in coil, the better the flavor.

I still have some 28 awg & 30 awg Kanthal to try that I received with the Nichrome.
