Viscosity and wicking.

[mattrix]

When I ordered my kit I got a handfull of spares (CE4, vivi, CE7), mainly out of curiosity as they all looked the same. As far as I can tell the main difference between them is the wicks,


* number of wicks
* diameter of wick
* length of wick





Which will work better for what?/are suited to different liquid viscosity (or color)?


I've seen mods recommending unravelling the wicks strands (to increase the number?, or reduce the diameter?) and others recomending shortening a wick or cutting one off (where you have multiple wicks/strands).


When would you do these. Presumably some prevent starvation with thicker liquids whilst others are to prevent flooding with thin liquids. Which do which?


A related question which are better for thck and thin liquids, top coil, bottom coil, cartomizers? This question however seems to be moot, as my research suggests people choose the device they like and then mod them to suit their liquid. Hense the first part of this question.

I like the single 3MM thick wick, it wicks thin and thick well (thin will pop and spit)

I can only give you my perspective as a 100 VG user: all top coils suck.

Seriously, in a very general sense I can't get behind the physics/design of liquid at the bottom, coil at the top. Then do you damnedest to battle the laws of physics and make that arrangement work. That's why you are seeing the "fat wicks, thin wicks, 1 wicks, 2 wicks" (apologies to Dr. Seuss), untwist it, snip it, swing it around and do a River dance variations in design - and how to fix it. Ultimately, the coils in any top coil I've tried all gunk up sooner than a bottom coil, because no matter what kind of dance you do to keep that coil at the top wet, you can't keep it as consistently wet as you can a bottom coil. They don't last as long before they need cleaning.

There might be an argument made that top coils work better with thin liquids. At the same time not too may people report problems with thin liquids causing flooding problems with bottom coils either. To the other extreme I'm using thick VG in Kanger bottom coil stuff and have no wicking problems at all with 100 VG liquids. And you will never get a dry hit with a BCC if there is liquid in it. Can't say the same thing about top coil devices.

You got 'em - try 'em. But if you aren't happy with the run time before they need cleaning, or get tired of the flipping twisting and rolling around to keep the top coil wet, the next thing to try is an inexpensive bottom coil like a Kanger T3s.

Took me a while to find this

I have, they all work, until they don't. I don't have the experience to work out why they stop.
Same for the MT3 I tried, I liked it at first but then it kept flooding the wick.
I think the top coils are more forgiving.

A good description for what I saw; but I didn't pay enough attention to why they did each of what they did. And I can't refind all those youtube videos
