love the music! Thanks for the vids!
Is that an eraser you've got on the roll of kanthal?

I will sell my soul to get that warm cotton taste gone.
Save the simple prep tips, and cotton types, I've done it all. Maybe I'm half German Shepherd...it doesn't go away.
Maybe your juices are strong enough to mask it...I mean it wicks killer, but, c'mon guys...
I deserve the secret...help me evict the cotton taste, as I love it's wicking.
I've tried everything short of expose it to radiation...

Less cotton, and let it soak a while... Than give it 15 minutes if continuous vape and squonk. I vape unflavored just like supe and 15 minutes later no more charmin taste 
I also use itty bitty amounts of cotton

Damn. That sucks. MySystemHasSucceded in that I taste cotton for about 10 or so hits then it goes away.
I vape unflavored nic in mostly VG so no masking.
I don't know what to suggest that hasn't already been suggested except please post a picture of your build and let us try to troubleshoot
"Then it goes away".
Shouldn't it have gone away during boiling? If it's still present after boiling, pretty much means it doesn't go away.
I knew it. Even just tasting it before it goes away will have me always tasting it.
Here is the bigger question, what is going on that it's lending flavor! That's scary. Maybe the operating temps of a coil are doing bad things to the chemistry?

I don't boil. Good questions though. I'm guessing that whatever is going on is pretty insignificant. It's such a small amount of cotton.
This is too easy to produce the tightest micro coil ever. You won't even need to heat and squeeze them to make em tight
Thanks to MacTechVPR for pointing me in this direction.
Vids are rough but you'll get the idea. No words even required - it's that easy:

Here's my preferred method using darkzero coi jig

Interesting. I did notice that the spool says it's already annealed as well. Helps in the wrapping too.
There are how many grams, if even one, of tobacco in a cig? Insignificance I think is the wrong term when it's done all the time, and a potential hazard could arise.I don't boil. Good questions though. I'm guessing that whatever is going on is pretty insignificant. It's such a small amount of cotton.
I do appreciate the help, even if it doesn't read that way.
Can't you tell I WANT this to work?
I don't boil either- use the cvs sterile roll.
Cotton Is porous- it's why it makes a good wick. Putting a couple squonks and hits through is opening up the cell walls to further saturation. You taste the wick before the cells walls become receptive.
Why does uncooked cabbage taste different than boiled cabbage?

Boiling should remove the taste then, that's opening up the cell walls on a level vaping doesn't get to.
If it lends flavor, the heat is prob doing not so good things to it. We are mildly burning, or heating organic material to these temps.
And we all know what organics give off when heated to a certain point, and it ain't a flavor...

Why, Organic of course, but I've tried it all ways my friend.
So, with the subjectivity of "the taste goes away the more I vape" aside, can we agree that there will always be a cotton taste?
I've tasted cotton before I boiled but after a good long rolling boil on some cotton balls I don't taste anything, even from the first hit. I've since switched to hemp which takes even more prep than just boiling but with proper prep, even with hemp I don't taste it even from the first hit, but that's only after much soaking and scrubbing in oxyclean and then much boiling and rinsing.
I think it's possible to boil cotton balls enough that there is no residual taste left, not so sure about rolled or organic though, I've gotten them clean enough for no taste with just CVS sterile cotton balls... I don't think what you are tasting is directly from the cotton itself heating, it's more what leaches from the cotton into the juice on first priming, which is why it goes away eventually, IE: the cotton eventually is cleaned by the juice, but you are tasting what's being "cleaned off" or leached off until then. boil it enough and the taste should go away completely

Pictures, as promised. Incidentally, I measured resistance. A foot-long coil is about 0.8 ohm.

I'm going to agree with the coil wrapping discussion going on here, but also going to add that having the whole wire in tension is not what's really the critical issue. what is the critical issue is having the part of the wire currently being formed to be under tension. a full wrap is 360 degrees of rotation, a coil being wrapped is really only under deforming tension for maybe 15-20 degrees at a time, at the leading edge of where it transforms/bends/reshapes as a ring from a straight length, spiraling around and around, forming wrap after wrap.
unless you are applying enough tension to actually stretch the wire, which is not happening at all with any hand wrapping, then the important thing is that the wire has tension right at the point it is being reshaped from a straight length into a ring. I agree that doing this uniformly and consistently with conventional hand wrapping on a stationary jig is not possible and this became immediately apparent to me from my first time wrapping around a tiny screwdriver. wrapping with the over-back-down-forward-up type motion of wrapping to a stationary jig is virtually impossible to do with consistent tension and pressure at this critical point of transition, which is the point where the wire goes from a straight length to being formed to a tight ring.
the tension method shown here is very good and achieves the goal of consistent pressure and opposing force at this critical point of transition, the point where the wire is being re formed from relatively straight to a tight diameter ring. kudo's for that, it is a very good and consent method of achieving the goal, BUT, I have to say that although this is one way, and a very valid way of achieving that goal, it is really not the only way, and I believe that pinching the wire tight enough at this same point of transition will achieve the same or at least very similar and equally consistent results.
if you study the engineering behind cold mandrel bending and extrude forming, cold metal forming in general and what happens when metal is re shaped you'll understand how whats happening is really only happening at this one specific point of wire at a time, at this ~15-20 deg radius of re forming at any given point of wrapping. pinching the wire tight enough at this point of transition will achieve about the same thing as pulling tight as you wrap against the tension. both are causing the high pressure deformation at that single point of transformation. your pinch at the deforming point acts as a mandrel. pinching tightly while spinning the forming jig can accomplish very much the same thing as pulling and then spinning against the tension and result in just as even and consistently uniform
I've been saying this for a while now and I do get perfect tight coils with just the pinching method, so perfect that no annealing is ever necessary and more than 90% of the time I wrap a coil with just pinching as it's wrapped it goes on the mod and fires perfectly, from the center outwards, with no need to even squeeze the coil after the first heat up at all, and this is all with just a smal length of wire not even on a spool.
so bottom line to me is, wrapping like this is a significant improvement over wrapping on a stationary jig with hand over-back-down-under-up etc... but it's not the only way to accomplish this. I still think spinning while pinching is the easiest and quickest to me but you need 2 things, a very strong pinch with tough fingertips and a crank handle on your spinning form to be able to keep enough tension and pulling as the wire is reformed from relatively straight to a series of tight rings in a spiral. of course pulling tightly to a drill bit in a drill and then spinning it up with the drill will too achieve these results.
this is how my coils come off with just pinch and twist. my whole point is not to knock this method as it is great, just not the only way, and not necessarily superior to other methods which can achieve the same results

I'm sure it's just the way i think, but i thought that video looked like me trying to open a can of corned beef!
Sure looks easy - i'll give it a try on the next coil i make for my guinea pig (HRH)
