Coils R Coils

[vapdad]

I've seen many vids on how to re-coil a wick (4-5 wraps). They all advise that the coils should not touch one
another.

Today I watched a couple of vids on making 'micro coils' (8-9 wraps).

The coils on the 'micro coils' were squeezed together so that there were no gaps between them.

I'm at a loss to know why one has to be loose and the other tight.

Can someone enlighten me.

Cheers.

With a micro-coil, the generated heat is concentrated in a small area, making the vaporization more efficient. With a standard coil, it is spread out over a larger area. Micro-coils are more efficient in their job. But, good wicking is even more important with a tight coil wind.

I have changed over to micro-coils exclusively for this reason; I also use only cotton or hemp for wicking.

They still need to do a little messen' around to fully capitalize on micro coils. Consistency seems to be the drawback because of wicking problems (I really don't care all that much for the taste of fried cotton wicks, and it's soooooooooo easy to do)

So I say let the experts work the kinks out of micro coils, and in the near future the rest of us will really have something to shout about.

It's just a "style" or classification of a coil. You're right IMO, Coils R Coils. But not all coils act the same. The main reason for separating coils historically is "hot spots" and shorts.

The thing with micro coils is they dispel a lot of the myths surrounding hot spots and shorts. It turns out that oxidized coils don't short very easily.

I agree with tj that burnt cotton (all too easy to do with a micro coil...center just goes "poof") is not fun. You can use em on silica though. However, that's still a wicking problem. So then we get into...how many wraps classifies as a micro-coil?

Just wind the dang coil, check for shorts, and find a way that works for ya.

This is actually the opposite of how micro or stacked coils work, the heat is spread out more evenly over the coil as it heats up.

Thanks guys for the replies.

I still can't understand why 2 coils on a 4-5 wrap touch and cause a problem. Whereas on a micro coil, they all touch and no problem.

It's just that curiosity has got the better of me. Yes, I know "Curiosity killed the cat". But "Satisfaction brought it back".

Cheers and thanks again.
