Rave-on for rayon?

[davetherayon]

Third atty : a Squape. This is interesting (I hope). The unique shape of the Squape is so it's easier to thread wicks through the coil, which is very true, but how does rayon cope with walls on either side of it?

Here's a pic of the cotton wick I replaced.



and this is the Squape with the rayon wick in situ.



Dripped it with RA, and popped it on the Atmizoo Lab mech mod, straight up full power on a full battery. But what is this? Tight draw and no clouds. Took a few toots and dismantled it, and this is what the wick looked like :



Bad pics as usual, me being crap at focusing with the phone. But hopefully you can see, ONE side of the wick had drained on the top side, and the other side was fully RA'd. Weird! Wonder if the wick being wider on one side was now too tight, and not vaping properly given the confined space it was in. It's almost like the rayon was occupying the space so much that the juice literally had no room to flow.

I took it apart again and tore off a few bits of rayon from the whiter side (again, so easy with rayon, threads just come away when you give them a pull) and had another few toots. Still thin vapour. This warrants more investigation.

Toot toot!

Edit : this was using a 1.4 ohm coil.

Editedit : Problem solved, schoolboy error! The Squape airholes are in the bottom thread, and the Lab has no air feed into the 510 connector! Just popped the Squape on top of a Vamo, cranked her up to 5V, and the toots be tootin yo. Lesson to self : don't use attys with a 510 air feed on the Lab!

Interesting findings davetherayon. I've been testing the rayon since I got it on Saturday and so far, I am liking it. I went square with reading the American thread which gave me an in site into common problems or issues that were happening and always it seemed to be either the wick used was too little. During the testing phases it was recommended to check the wick after an hour of vaping. If the wick is not fully touching the coil the. You may get a harsh, metallic hit. There were also some stars who had the odd burnt hit and I think for those they used a tad bit too much.

On my first try in a protank I must admit I was not that impressed, I don't think I got the density quite right but when it was time to wick my kayfun I tried again. I have had the same rayon wick since Saturday and only today has it started tasting a little off so will be changing it tonight.

I am finding that the rayon does have a little break in despite what has been said and that to me, I do not detect a wick taste. For comparison I rewicked a tank that I had done with rayon to organic cotton wool and straight away I could taste the cotton for the first half hour or so.

I find the rayon is giving another dimension to my adv and I am not quite sure if I like it or not, it is definitely a clean taste but almost too clean and instead of increased sweetness that some users are finding, I am experiencing a kind of saltiness.

This will need more experimentation. I don't have many different tanks but am testing on the kayfun and the Protank/aerotank series to see how I get on.

Mrsmac thank you, I thought this was turning into a blog I'd be interested in finding out anyone's experiences with rayon, and my offer on page 1 stands of sending freebies out (postage paid paypal, no rayon cost, god knows I have enough of the stuff). I'm pretty impressed so far, not one of the 3 attys I've built have gurgled or leaked, including the Taifun that I was getting a bit cheesed off with this week as it had decided to leak *every* time it was filled up.

[Mrsmac]

Lol, I think you will find that some are lurking to see how it goes and I don't blame them, cotton wool is so known about but not rayon. I am defiantly not an expert and have read the majority of the thread on ecf and from what I see,vi am willing to give it a try. I find that for my 2mm coils I cut a one inch strip and take away just over half. On ecf I think they use that peice but I cannot get it into the coil so I use the other side, just under half as it is sooooo fluffy lol. I do need to test my salty theory though so tonight when I change the wick I am going to use cotton wool to do a direct comparison whilst fresh!

[davetherayon]

I'm planning on trying a dripper with it next. First to see how a dripper with full mech mod goes, and second to drip something like RA onto it, replace it with I dunno some chocolate), then something subtle like RY4 (relatively subtle compared to those behemoth juices) and see if there's any aftertaste. Bleeding edge!

Edit : chocolate, not menthol. RA has menthol nibbles I find (are my taste buds that shot?)

[davetherayon]

This was a PM to ronaldo but I thought it worth sharing as it is a brain fart that makes sense :

"Where you normally tweak cotton in so it slides in easy and there's a definite gap in the coil, you DO have to make sure with rayon that the inside of the coil is fully packed, and guys on Ecigforum swear by having a 'shoulder' on either side of the coil, the 'filter shape' I mentioned in one post. Makes sense, rayon is better at chanelling juice than cotton, but doesn't hold it so well, so have a good lump of rayon either side of the coil as it burns so it is juiced up while the slower-moving juice makes its way to it."

I have been following your "blog" with interest davetherayon (DaveTheRayon), I tried a couple of times in Kayfun clones last week, I found it very easy to work with and a very clean taste to start off, but I don't fell I have the hang of it yet: too much or too little and need to do more experimenting. I can't put my Karken down at the moment and the prospect of vaping a cotton wool type build is not that inviting, but I will probably get to again this weekend.

Good info from davetherayon & Mrsmac, keep up the good work

Tobh time! Lets see how this works in a dripper.

Here's the Tobh set up with a 1.3 ohm coil :



and loaded up with rayon and RA ready to vape.



Using a mech again, this time to plough through the juice asap. I am over-nic'ing for science! Also, by popping the atty top it's possible to see how the well of juice is being absorbed, and if there's any dry spots developing on the wick or coil. After a few bursts, again for science! I opened the top and just burned that mofo juice off, also I was getting a bit of a nic high.

Interestingly, with the mech running CONTINUOUSLY on for 30 seconds, with the Tobh top off, there was NO hint of burning, and the mod (a clone Nemmy in 18500 mode) was running cool. So props to the coil for that.

With a good lot of the RA burned off, I swapped to the nearest equivalently strong taste juice I have, which I've nicknamed Mars Bar (it's called 'Work rest and play' on the mixology site )

Took a toke of it, and well whoa, the choco flavour was all there, and no remnant of RA. Again partly due to the rayon, and partly due to it being a mech pumping a dripper, the chocolate was almost chewably flavoursome. Really nice.

Took a few more tokes of that lovely stuff, then changed battery (we don't want to over stress the battery, do we folks! Safety first) and did another 30 second blast to say bye-bye to Mars.

The room by now STUNK of chocolate, and in a good way - there wasn't any burning smell at all, it just smelled like a chocolate factory lol).

Now for the real test. Totally different flavour, some RY4. Filled her up, and.... tobacco straight up, no choccy taste left, RA history.

A very interesting observation is, that the RA COLOURING remained on the wick all the way through - albeit lightening phase by phase - long after the taste had gone. So, rayon retains colours (amazingly considering its use in ummm fabrics!).

That's my testing regime done for the night, possibly the weekend. Got to get to using this stuff for real now!

Toot toot!

brilliant we just need to get people trying it now as the more that try the more we learn then we can pass the info on

[Mrsmac]

Here is my wick from the kayfun. Wick last changed on Sunday only started tasting off today! Run at 1.6 ohms at 7.5 watts

[davetherayon]

Don't know what you're vaping on it Mrsmac, either it's holding the colours of each juice or you really really like an orangey juice

[Mrsmac]

Lol it's grape, it I'd clear but turns an orange whilst stepping. Incidentally just rebuilt with cotton wool and can taste a film in my mouth now. That was but there before

[davetherayon]

An observation on filling, based on watching my Squape. It was getting a bit light on vapour just now, so I dismantled it and found a good bit left in the reservoir, but the lines into the coil were a little light, could tell as this is the one full of RA! So dripped them, and all is good again. Rayon is definitely less drawy than cotton, at least on devices like this... not sure how the kayfun's playing out, I'll have to dismantle it in a bit and see how the juice drawing is performing. Hopefully it's just another Squape thing.

Edit : Schoolboy error removed. Just checked it this morning, and the juice is definitely having a problem moving through the wick, both sides of the coil are pale compared to the ends nearer the base of the atty deck. It does look like the Squape has issues keeping the coil fed, which is a shame as it's one of my favourite attys. Not going to stop using it though, it's vaping nicely.

[davetherayon]

The Tobh has now been tooted right down to the last, it used up every bit of juice that was in there - even the RA colouring has gone. The wick is as clean as when first installed, and no shrinkage in the coil, no signs of caramelisation on the edges of the coil. So packing the rayon in seems to have the desired effect.

[davetherayon]

The Aga T was sat there looking sadly at the newly rayonned attys, so it had to be done. A Genesis rayon build. This fella was a fiend to wick with cotton, how would rayon do?

First stage was to completely dismantle and clean the thing.



Built a coil, 8 winds of .28, and attached it to the posts. 1.3 ohms. Then, some rayon was threaded through the coil, into the deck hole, and teased into place with a needle, pushed down from the top of the coil. This was the Devil's own job, involving pulling threads off the top when the wick was too fat to go in, usually removing the whole wick in the process, but eventually it was in place.



Filled with some menthol I had lying around (for a change.. I'm not usually a mentholator) and on 3.4 volts on the Provari, it's quite nice! The taste is VERY strong, a fair amount of vapor (not cloud cuckoo land though), but pleasant.

Would I recommend rebuilding a Genny with rayon like this? To be honest no, fiddly as heck!
