That's what we look for though. Quick to absorb and holds a good amount. The faster it absorbs, the less rest time between uses. The more it holds, the greater the amount of puffs before risking a nasty hit.
Now when you get down to the details, there is no real difference between cotton and rayon other than the density. What kills cotton performance is fiber orientation and fluff(the little pills you see in a cotton ball). Combed cotton, like what is used in KGD will perform just as well as rayon (not counting taste contamination).
Imagine the fibers are a couple of identical streams side by side. Water will flow equally and easily through both. Now if you dig a few pools connecting both streams, you will change the flow rate causing it to slow down stream of each pool until the pools are full and equalized.
If you add a siphon (the wrap of a coil) in between the pools, the fill rate of the pool down stream slows and the overall flow rate after the siphon slows. The more pools, and siphons, the worse the flow gets.
That's why some cotton balls wick better than others and also why cotton gauze is the worst (mostly fluff).
Hmmm, wicks are tricky. Density is really important. Not only is fluid pulled to the coil but also, in a tank, air is pulled back out, ideally at the same time.
Vacuum, pressure, (or other air exchange) is a function of Atty design for the most part. Different designs rely on it more than others.
For wick testing I am choosing to not try to replicate a vacuum. In large part because I have no clue what to use as a baseline. No matter what I used it would be debunked as not applicable to atty XYZ.
Capillary and capacity are all I know to measure that should translate across most any atty.

Vacuum of the tank does not affect wicking performance of the material. That is a myth.
All vacuum does is affect the flow of liquid to the wick chamber. That's not important when testing wicks.
Agreed.....
It does affect flow, and some materials may flow better than others, but how well a "specific" material flows is independent of the vacuum.
Have you thought of doing siphons?
As long as the 'output' end is lower than the 'input' end, the wicks could be cut to the same length/weight and draped over the edge of the 'input' beaker and then use timer and measure the weight of the output ends. (beakers)

Yes, I have thought of it, but so far using the original rig is still in the lead, unless someone can tell me how/why that wouldnt be a sound method.
That wouldn't be an issue. Get with me when you're ready to do your "sticky" post. Once posted, I'll immediately sticky it and then we can add to the original post as needed. You may want to "reserve" the next post or two after the original just in case you run into the maximum length for a post. Just make a quick "reserved" post after the original so it's all together as you add to it.
Deal?
Or.......
What if I printed a short blurb, ie brief intro, with that list of links, and asked you to add it at the end of the opening post for this thread?
I kinda like that better than a new thread.
But I will be happy with either approach.
I am cross posting this here since it is testing these tiny azz coils that is driving me too this:
OK, I admit it, I am getting old, or at least my eyes say so.
I am looking for some design similar to below but with a 5x magnifications at a focal distance of 12".
A casual search of Amazon only turn up junk.
Can anyone point me in a direction where I can find a proper pair? Or any other adequate design, they dont have to be inexpensive, but they do need to be good quality.,
These are junk, and inadequate., or at least the pair I have is.
Many thanks for those for offer suggestions.
I'm 60 and my eyes are not the best anymore even with glasses. I do small precision machining sometimes, I sew (try threading that d**n needle sometime
) and all my atties are rebuildable. I tried a couple of cheap headband style magnifiers and found they didn't last long but I liked that style of magnifier. Once I got my Donegan Optivisor my search was over. I added one of the aftermarket LED lights to it once I knew I was sticking with it. I've had it for a couple of years now and it's till as good as new. It fits over my glasses easily. Here's a pic of it:
I'm currently using a 2.75X lens with a 6" focus distance and I find that very good for atties. I prefer 2X at 10" for machining, but sometimes if things get really small I'll put in the 2.75X for that too. The higher the magnifiction the shorter the focus distance and depth of field get. There's a chart of lens options on the Donegan page here.
You can get lenses in both glass and plastic, the glass ones being more expensive. I have one glass 2X and a few 2X and 2.75X in plastic. I can't see the difference in optical quality between glass and plastic and even after using plastic in a hobby machine shop for a while I have not scratched them yet.
I don't know if you can get higher than 3.5X lenses, but the focal distance would be really short. FWIW, I can't imagine needing that much magnification for coils, but that's just me and my eyes. I suspect for more focal distance at higher magnifaction you would need to get a lens system that uses multiple optical elements, like camera lenses have.
Hope that helps a bit
ETA: The light makes a big improvement to the systems performance, specially as the focal length gets shorter.

Wally World $3 reading glasses + free from X-Mas tweezer-hands magnifier stand is what I use for rebuilding. You old farts are really old. I'm only 56. only.
EDIT - Sarcasm doesn't read well on the interwebz.
Mrs. M. subscribed to AARP a few years ago. I coulda kilt her.
"Your magazine is here you old fart!" sez me

I threaded one of your builds, coulda seen that from across the room.
Try sticking a 40awg sensor in a protank coil, and reassembling it to vape, then lets talk.......
You young whipper snapper.......
Mike, this may be one of my wacky ideas, but after nearly 3800 posts, I think you might bring newer vapers, and older vapers who are not following this thread (for any number of reasons) to a new thread.
My idea, shun it if you like, would be to actually start a new, fresh thread, and perhaps title it something catchy, like your blog - maybe something like "Best Practices for Vapers, including non-TC vapers, by MikePetro". Perhaps even something more short and sweet, like "BEST practices for all Vapers".
You could start with your Draft #3, and link to your blog and all other links you like.
I read the edited first post here. I'm not sure the general vaper would even get down to the end of that post to see your links.
There is a plethora of info there, including charts and graphs and vids, and I have a suspicion that many would simply skip right over this thread. Your edit is great, but it's truly only for those who are already here.
If you want a larger audience, you might consider my idea. (and please know that for me it matters not if you do or don't.)

I may well do that before all is said and done. For right now I am trying to salvage this thread. Because if all goes as according to whats been promised me, I will have more studies to post soon, and the hornets nest will get kicked once again. Being able to direct people back to the opening post "feels" convenient", I guess we will see.Mike, this may be one of my wacky ideas, but after nearly 3800 posts, I think you might bring newer vapers, and older vapers who are not following this thread (for any number of reasons) to a new thread.

Anyway, this thread certainly took off, and in a totally different direction than what I would have ever predicted, and it aint over yet, the rotund lady is not singing yet.........
Mike, it might be helpful to split it out as a sticky and redirect anyone who wants to get deeply immersed to head over here. I have no doubt there will be lots more data coming down the pike which will hashed over and the conclusions debated. I would be concerned it's asking a new vaper a lot to jump into unless they truly understood the process and wouldn't do a quick interpretation of "wow, this stuff is worse than vaping benzene!".
No right or wrong, just whatever you think is most useful to a new/newer/established but doesn't get all too involved in stuff vaper.
Somehow, not sure of the method, but Mooch does an Index Page to all of his Blogs. If and when I get enough I may opt for something like that.
Honestly, maintaining one thread is all I care to chew. I will fight the good fight, but one is enough. And for right now this is the topic I am sticking to. I dont think this story is over, and I will see it through. Dont really care where it goes either, I just want the truth. If Wang and Geiss are proven to be wrong, I will be the first to post it. But I dont think they are wrong, and I do think that more evidence will come to light to back it up.
So you are likely to see me here lobbying for TC mods for a while, or until something better and safer turns up.
I have invested in NFPA ARC Flash Category 4 gear, so I can handle the heat..........
But if you do flame me, dont expect me to lay there quietly.......
