Seen a lot of talk about microcoils this morning. Hopefully I may be of some assistance.
It's not the number of wraps that determines the resistance but the length and gauge of the resistance wire.
The bigger the gauge of the wire the less resistance it has over the same distance. 1 inch of 28g has less resistance than 1 inch of 32g.
Microcoil is simply wrapping that same length you would normally use for 4 to 6 wraps tightly around a smaller diameter shaft to get 9 or 10 wraps.
The nail on the right is a 1/16th finishing nail that I use for micros. This picture is actually a nano I wrapped on the needle on the left. Note that the wire isn't touching completely in all the wraps. That is because it's nearly impossible to do with 32g wire. I got it tight enough to drop the resistance a bit but not as much as it would with 28g getting them all snugged up.
A nano is simply a microcoil with an inner diameter of less than 1/16 or 1mm or something along those lines. It's pretty much "yay we did the exact same thing but smaller so we can call it sometime different!".
Even if they're not all touching you'll know that you did it right when you pulse the coil and it starts glowing from the inside of the coil and goes outward (like when Kit talks).
The micro will give you more heat quicker because the coils are heating one another due to their proximity to each other.
If possible try doing it with 28g or 30g. It's a little tougher to do the coil but easier to make it touch. Remember to torch it before you wrap to make it more pliable.
Hope that helps.
