Rayon wick, better flow, flavor, saturation and Nic Hit!

[etherealink]

Whoops, forgot to put the ladies in front of the gentlemen.

Coil is wrapped around a 3/32" mandrel, so about 0.156" smaller than 7/64". However, it's twisted 28 ga., so it probably does appear chunkier. I always fluff the hell outta my rayon, learned that with my Rose V2. And thanks, cindycated, HolmanGT, I think the only thing I haven't done is an above the deck. I'll try an "inverted" angle trim (where the trim is from the 'top' of the coil to the bottom), which might help with the shorter tails 'growing' to block the juice flow channel. I think the raised bit might help the most, however.

I'll report back later when I rewick after this latest tank; it's doin' a bit better after I did some additional fluffing, but it's starting to go backwards, so...

Anyway, keep on vapin', everyone!

KGS, no matter the tank or rda I stay to one basic idea that seems to work, even if its a bit sexist... make the wick look like a cheerleader's ponytail.

It gives you a solid taper and good contact (assuming you have good density) and let's the juice travel as the wick does its thing.

Sadly, I have learned that "not fighting" your build is the hardest part to rebuilding. Let it vape for a while and check it, adjust accordingly and continue. Eventually you will have a 100ml build and more.

Vape strong!

I've got a Squape R FastTech Clone that works great for me. I chose to place my coil and wick above the channel because I don't trust the E-Metal coating on this clone. Here is Ni200 coil and wick. See if this might help you in any way:

Slinky coils!!

Well, this is troubling... I'm havin' some trouble gettin' rayon to work with my Squape R and I'm stumped. I've tried several types of wicking techniques, and I have a tendency towards dry, ashy (not dry, metal-y) hits, which go away briefly after sitting for a while, but come right back after two or three hits. It doesn't really matter how tight the airflow is, either. These builds are Ni200, with my Hana Modz DNA40.

Kinda late but will continue what I started writing yesterday...

Sounds like its too tight in the coil kgs.. It's very easy to go too dense with double wick. You need to use long thinner strips so you get even fluffy density going into the coil through to the other side. I find rayon always works best if it's not compacted

Dry ashy is too dense, the fact that if you let it sit and it's good is showing that it's not wicking obviously.

Glancing at the picks you posted, with it inside the channels like that you need a smaller coil to let the rayon breath a little.

It does look like the airflow is restricted heavily...?.. A smaller coil, 2mm maybe, will keep the rayon from being choked in the channels. I think that's the issue.

If you must use a coil that big raise it up above the channels. One way or the other should help you.

Understanding the functions of the wick.

Thanks for the feed back. Exactly what I recommend. Here is my philosophy-

The whole wick is like a life form. The biggest/ thickest piece being the heart of the wick which juice flows to. You want that heart in the coil. So thinning the tails helps achieve this. If your build doesn't automatically make the the coil the heart.

Second the rayon does not absorb juice into the fiber like cotton. The juice clings to the outside of the fiber and flows in the microscopic fiber channels. This is where it flows. Depending on the set up a thick tail can pull the juice back from inside the coil. In an ebb and flow.. Coil heat draws juice in, heat off - the thick tails pull juice back out. As you mentioned this will show in the tails fairly quickly. And is an indicator the your having back flow after vapes. *Not the best scenario if you want a centurion wick.(100ml)

If you make the densest piece of rayon in the coil, the rayon will direct its flow towards the heart. If your wicks are straight to the coil the natural flow of a gutter will let the juice ride in without much problem. But Back flow can still be a problem though because this may increase gunking by double firing the juice that's already caramelized. Juice going back and forth through the pipe.

A long lasting wick and coil is efficient. It vaporizes all the juice in the coil and is constantly fed by fresh juice. Vaporized juice is gone & after a vape your left with fresh juice in the coil. No gunk!

Hope you don't mind me borrowing the post mate. A friend of mine is struggling a little with his rayon. I've tried explaining it to him, but your explanation is much more eloquent

No problem guys!

There's so many valuable posts that have been made here by Me And Others. I was just trying to dig some up for new users this am.

Rayon people,
Someone gave me a little bit to try out, but didn't really give me much instruction. I don't know anything except that it is supposed to wick better. I'll be trying it out in an orchid and with some rdas, what are some basics that I need to know? This thread is huge, and I've read through a little bit, but if someone wouldn't mind listing a few things, I'd appreciate it.

the way it wick is similar to my aiolos, so barlly have it ran down the channel an have it loose an same with coil.

I still keep it loose, to the point where if i slide the wick in, my reo grand will stay put while i slide the wick back and forth. BUT you actually do want to use more rayon than you would cotton because rayon will not fluff out and expand like cotton. Rayon kind of stays the same size or maybe even shrinks alittle once saturated. That being said, i love rayon. I use it exclusively.. where as cotton is absorbent, rayon wins because it isnt as absorbent so it transfers juice much better to your coil. I do get like a "cardboardy" taste for a halfhour or so with a fresh wick but it def goes away and it gets AMAZING. dont let the first few hits deter you. It gets wayyy better. Best of luck.

First off kudo`s to JeremyR for bringing this to the light of day. I have been reading this thread and have made it up to the 300`s and decided to take a flying leap off the rayon cliff. So I went and visited Sally, and all she had was a refridgerator sized 3# box. While it states clearly on the box 100% rayon I am questioning my purchase based on earlier posts about there being two types. The item number on my box is 44043 is the stuff? And if it is I will be more than delighted to share some with anyone having trouble finding any, even you vaperz from udder countries. If you are having trouble getting this mysterious looking fiber through customs, I could have my daughter to crochet you a small animal stuffed with, you quessed it MAGIC WICK

Yes, that's the right stuff. You got the nice big box like I did... now you can give it away!

Thanks for the thoughts, everyone, and thanks for the reminder that rayon's a tough wick to master, JeremyR

For what it's worth, the wick came out easily, so while it could've been tight, I don't know. So, just in case I'd screwed up something completely, I recoiled as well, made a twisted 30ga., 0.1Ω, wrapped around a 3/32" mandrel (due to springiness of twisted Ni200, it ended up being somewhere between 3/32" and 7/64"), which is smaller within the Squape R's atomization chamber than my last wick. I also, as can be seen in the pics below, inverted the coil so it sits above the deck. Did a double insertion, but with somewhere between 2/3 and 3/4 the wick I used last time. Oddly, the larger amount was the normal amount of wick I used with rayon before in my Rose V2 and drippers, with no problems, so I guess the Squape R wants to make sure rayon fans are on their toes? Runnin' 38W@430°. Vape flavor's spot on once again, vapor's about the same, throat hit's as good as always with Rayon, and so far, no dry hits with the Squape R's airflow at max (3.1mm), so I'm a happy, happy camper!

Here's a couple pics, overhead first:

And front view:

As can be seen, it looks a tad lumpy, but looking closely from more angles, I've noticed that there's about the same amount of rayon within each channel and the vape quality's solid, so I can't really complain about the results!

Thanks, and keep on vapin', everyone!

Glad you figured it out .. I'm guessing the big coil down in the chamber was the issue. Who knows, but you did it !

 

[cobalt327]

I've been using "medicine bottle" rayon (MB for short). I just opened my box of Sally's rayon and I finally know what the "squeak" is, when the wick is pulled back and forth in the coil. The thing is, my MB rayon (and it IS rayon) never squeaked. The only thing that could account for this that I can think of is I boiled the MB rayon and did not boil the Sally's. Anyone here boil their Sally's that can tell me if they get or don't get the squeak?

I got my pre-made coils from FT Their internal diameter is 1.5 mm -- I think the same as the stock Protank coils. These coils are 2 Ohms and feel sturdier than the stock 2.5 Ohm coils. I guess they are lower gauge than the stock ones.

https://www.fasttech.com/p/1611706

I also got myself the drill bits below to use as mandrells.

http://www.harborfreight.com/High-Speed-Steel-Micro-Drill-Bit-Set-30-Pc-61526.html

The 1.5 mm bit fits perfectly into these coils. The 1.8 mm bit fits perfectly all the way to bottom of the Protank coil head housing. If start wrapping my own coils, I can use the 1.8 mm one with Rayon without over stuffing it much and hopefully won't need a top/flavor wick.

I've been using INW Am4a (Inawera Amphora) with some Tobacco absolute and the coils are getting gunked up pretty fast like within 5 mL or so. The flavor drops quite a bit after that
