Now that I've turned my attention to the ends of my wick, I wonder how much of my 'issue' with the cellucotton rayon was actually operator error... I'm willing to bet, it was all me... lol I guess I'll have to give it another shot...I found it easier to pooouf rayon without breaking the fibers apart like cotton...
Question about twisted coils... Do you wind twisted coils using the tension technique?
I'll explain it this way. There's no perfect wicking material. Flavoring is full of pigments, complex molecules. The richer the spice, the greater the flow (power/wick) the more agglomeration. Think sponge. Eventually you saturate. Time to rewick/wash/chuck. It's the physical universe. Some wicks tend to trap some kinds of pigments more than others, some more or less quickly depending on power (tobacco notably). I think rayon's excellent for less complex juices, KGD exceptional for the rich, ceramic fiber more neutral and more powerful than either. Getting the density right with any loose fiber like cotton or rayon takes practice and research as it varies for each device and wire/wind combo. Rayon I find to be trickier. Ceramic fiber exceptionally fast and predictable in flow and for installation. Japanese cotton absolutely exceptional for flavor. Organics for anything you can rewick routinely; ceramic fiber for those that
must last days or weeks.
Problem for me is I'm flavor sensitive and can taste the nuances of each and every one of these materials. And cotton I can't "cancel out" as one can with use like silica. It becomes rather neutral, background. The residual taste of kilning of ceramic fiber though evaporates with use. What's left for all of them is that they exhibit a slightly different texture in the vape which we all of us perceive as a factor of
taste. I find rayon for ex has a markedly drier texture and it makes for a diff in the flavor with some improved, others not. Cotton is luxuriant in its texture…wet, full and moist. Ceramic fiber far more neutral, increasingly so as it breaks in and that is a texture in and of itself.
Twisting wire is a PIA and if you use a hand drill you must tension the wire somewhat to keep the twists consistent and tight. It's a learned skill. Tension too much and you'll snap the wire prematurely. Worse still, the results vary depending on your drill (speed, torque). But I've loved twisted for the increase wick contact surface. I teach basic tension winds to get new vapers to the great vape fast. But multi-wire's been the ticket for me. And
yes tension winding the coil itself with twisted will help get a better turn-to-turn adhesion for oxidation so you don't have to torch (but will require compression as you pulse). It will not get the coil to static adhesion. So it's rarely coherent enough to behave like a true microcoil. Such coils can be made to get cooler (higher phase transition efficiency) with tension, just not reliably.
That's why I had to work out stabilizing tensioned parallels with twisted leads. Benefits of improved light wire contact surface, not too high a res for the mass, fast firing and rock stable leads that resist separation and protect the tensioned element's integrity (easier, controlled installation). A great compromise between twisted and parallels (more wire mass/wick contact effectively deployed, more vapor = more flavor density, with warmth). Yes they're a little warmer than twisted. A lot less fiddly than havin' to drag out a hand drill every time ya wanna vape.
Anyway some thoughts on this for you and hopeful some will try this. It's not a beginners build but I find it no more difficult than twisted pair. And you gotta admit, it's pretty.
Good luck vj.
