It’s been a while, but I’ve read through a lot of the (in)famous rayon thread on e-cig forum. It seems to me that both the production of rayon and cotton would scare people away but that doesn’t mean the end product isn’t good for what we use it.
I don’t get on with rayon either, but simply linking that you’ve worked with plastics and therefore won’t touch rayon is probably sending out the wrong msg. Both are equally good to vape on. There’s plenty of documentation online to support that and plenty people have been using either or both for years without any ill side effects.

@anon28032772, @SessionDrummer:
I’ll start with a new coil in the dead rabbit rta. For demonstration purposes, I’ll use a 4" -5" piece. I usually can use smaller. Twist the end to compact it. This is a full thickness piece out of the box in a 3mm+ coil.
Twist and pull the rayon through the coil, without distorting the coil.
Untwist the end that was fed through the coil and try to fluff it back out. Separate each end in half.
Trim both the bottom halves even with the deck. Depending on the atty, sometimes I’ll trim as flush to the coil as possible(profile rda being one of them).
Next, thin/fluff the tails. You want to be able to see through them. Should be less than half of what you started with.
Cut the length of each tail where they protrude through the wick slots.
Next I take my fluff tweezers and grab the wick as shown and pull the wick out of the slots and trim flush with the bottom edge of the tweezers.
Once they are trimmed again, lightly fluff the ends and start priming the coil. Add juice to the tails starting near the coil and allowing gravity to pull the tails down. Sometimes I’ll have to lightly coax them back into the wick slots. The wicks should be somewhat flush with the wick slots when fully saturated with juice.
I make sure that there are spaces on one side of each of the tails. Put the atty back together and fill the tank full of juice. If the coil was properly primed, there shouldn’t be any rayon taste with the first pull. Sometimes I will get a slight taste on the first few, but it quickly goes away.
During the entire process of wicking, I blow any remnants of rayon crumbs or fuzz off the atty. Any questions, comments or concerns?

Very very nice @Deerslayer… excellent tutorial, pictures are nice sharp and crisp, easy to understand what it is you are doing with the rayon!!
I would change out my hemp coils, but I am stuck on a tea I am working on atm… with tropical fruits.
Hot diggity tho… tempting… I dont have the time to wick up anything till late this afternoon… but that is inspiration there!

I’ve always done something very similar to what you do here in my RDAs and I always got a mouthful of rayon taste. I get the same with cotton (cotton taste) when I stuff my coil so I learned the right amount to use. Now I’m hitting it every time with zero break-in, zero cotton flavor. With rayon on the other hand, it was always either a (pretty nasty) rayon taste or I wouldn’t have enough wick to fill my coil and that had other unpleasant side effects.
I guess I just don’t find the patience to keep messing with it while getting nasty hits when I have a perfect (for me) wick available.

You should call it the Einstein or the Don King wick.

Thanks @anon84779643. Someday I’ll get my hands on some of the hemp to try. If you get around to trying rayon out let me know if you have any questions.
@anon28032772 I’ve found that priming the coil is the key to eliminating the rayon taste.

Good names for it. Also heard it called troll hair as well.

Before you start with rayon… enjoy a read. This is the rayon thread on the internet.
There’s also a part 2 after about the 15000th post

Like I said, we all choose our own poison. Hell, nicotine is a pesticide. Rayon is polymerized wood pulp. The process embeds, among other things, formaldehyde and arsenic which are out gassed when heated. Some people are also allergic to the fumes created by heating rayon. Not going to criticize anyone for using it. I tried a hit off a friends once and could taste the plastic. Maybe that’s because I worked around if for so long. Some people can taste the metal when they use Kanthal, I don’t. I haven’t heard of any toxin’s released from organic cotton, but somebody in that field could clue me in. (BTW, that new car smell that everyone loves, is cyanide.)

Wow, thank you @Harlan_Grey I learned a lot from that post. Thanks. Oh and BTW, new car smell = cyanide ?? Who’da thunk that.

Fair comparison. I’ve heard about the “metal” taste in Kanthal too, and I’ve never gotten that, and it’s all I use. Love it or hate it, it IS actually pretty COOL, that vaping has advanced to where it is, where we have SOO many choices now.

Yeah, hell and I already always thin out my tails anyway, more on top and less on bottom is how I roll, sounds like a no-brainer. Worth a shot anyway!
