Thank you for your welcome. 
Hello,
I am new to the forum and looking for information on rayon.
I tried 5 builds on my KF prime before arriving at a result almost correct ... but I think it can be improved. Could someone post pictures on a KF prime or KF5 build? Thank you in advance for your help.
For information I speak French excuse me in advance for my bad English.
Thanks David
Unlike cotton, I tapered the legs of my rayon wick to properly feed the coil.
I read a piece of advice from the creator of this topic that said you should not hesitate to reduce the legs of the wick as soon as the wick is at an angle.
If I had this build in cotton version, I have no doubt about the dry hits and floods created by this build.
But whit rayon it work!![]()
For the leaking, Try stretching your coil to make it longer. You want keep the wick off the air hole block.Hey guys. Fantastic thread - many thanks to the creator and contributors for the wealth of information in the pursuit of ultimate flavour!
Hate to ask for advice with my first post, buy hey I need some advice
I'm struggling to make rayon work with the Siren 2. Using SS or Kanthal Clapton 26/30, 5-6 wraps on 3" diameter with Sanek Cellucotton (struggling to source better rayon in the UK). After wicking the taste and vapour are amazing for about 36 - 48 hours then the taste degrades and the leaks start. First slight weeping from the air holes building up to large amounts leaking through the base. Not huge amounts but enough to be annoying on a tank that is famed for its lack of leaks!
Wick is always very snug through the coil and I've tried all combinations of very thin tails, thinnish tails, thick tails, thin tails that are thick through juice channels and blah blah. Regardless of what I try 36-48 hours then blam. I've posted up some pictures of my latest attempt.
Any help or advice will be much appreciated..

Not enough wick, by looking at your images I can tell your wicking is too thin. Rayon shrinks, after the trapped air escapes your wick is just too thin.Thanks for the suggestions - will try and report back..
Salut Peco !Thank you for your welcome.![]()

Looks like I'm back to cotton. For some reason I'm getting better flavour with Muji pad. Ease of built also goes to muji as I can eyeball the width needed for my built. Can't get consistency in tearing apart Sally rayon. At times it's too tight till needed twisting before going into the coil and some time it's slightly loose. Either way it's not the flavour I can get from Muji. Keep subscribing to this thread in the hope that I would try rayon again.Day 2 - Rewick after 1 tank. Rayon is clean. Seems lesser gunk on same juice. Rewick with same half width of Sally on 2.5mm coil. This time round thinned the tails by cutting away at 45degrees. Very slight better flavour and throat hit. Kanger RBA in a Subtank mini and billet box boro .

Hello,
Thank you all for your help! I continue to experiment with my cellucotton but overall I remain a little disappointed.
On my KF prime the result is not regular, sometimes the flavors are perfect and soon after they degrade.
Always on KF sometimes the wick is well fed other times I have dry hits ...
As the KF prime is quite capricious with the wicking, I decided to mount my Fev in cellucotton.
My Fev are waterproof with cotton and I had a flood with cellucotton. I continue to work following your advice but I start to despair a bit.
