Digiflavour Siren 2 Airflow Modification?

[Northnet]

I'm hoping I have posted this in the correct section, but I'm sure a friendly mod will move this thread if needed.

So, I have a Siren 2 which I quite like, but it can be a PIA with flooding and leaking out of the air holes when it feels like it, or more accurately, when I have been a bit careless with keeping the wick away from the air holes block.

I have been thinking about reducing it down to a single air hole by blocking up to two outer holes and drilling the centre hole out a little to compensate. Has anyone tried this? Or what are the thoughts on whether this modification is viable?

If you are doing it for the leaking, learn to wick it better. It is not hard to build or wick, that atomizer. I regularly have one of mine surfing around in my purse. I don't think it's worth the effort is what I am saying. Reducing airflow doesn't really eliminate leaks at all, although it can slow them down some.

If you want some sort of different airflow that can only be done in that fashion IDK. It might work out, I t might be terrible, You could at least try putting the (sharpened end removed) couple toothpicks in there, to see how it performs.

IDK what you are planning to use to "block off" the airflow but I suppose something could be done.

Seems like a case of "too complicated, fix your wicking issues" to me, but I love that atomizer and build and wick it all the time, so....

Can't argue with you there, but I have a secondary issue with the vape getting harsh after only half a day. I switched 60/40, and then 70/30 to smooth it out, it worked to some extent but rewicking/coiling every day has been getting ridiculous. As you know I have invested in an Epro True and even though I coil and wick it almost identically to the Siren (longer tails because the Siren is 24mm), the True is a silky smooth draw in comparison.

Cocktail stick ends jammed into the outer air holes was my thought too, can always dig them out again if it doesn't work. I want to try to find a way to lengthen the coil so as to keep the wick away from the platform, but getting the coil tails back into the screw slots will be tricky. I just wondered if anyone else had succeeded with this sort of bodge.

For what it's worth, I recoiled/wicked yesterday and it hasn't seeped a drop, cussed thing. I am using the single hole on the air ring this time (usually use 3 holes in the slot), but I don't see why this should make a difference, maybe I just got lucky with the wick this time.

stols can probably be more help than I can on this tank, since I don't own one, but if it is getting harsh after 1/2 days use, in my experience that could very well be a wicking issue or a coil issue more than something solved with less airflow. Check the coil for hotspots, what are you using for wick, cotton or rayon? If it's too tight or loose in the coil it can cause it to get harsh.

Yer, I've only been messing around with coil and wick for six months (got bored with getting fleeced for pre-made coils). Getting the balance right between them is tricky, and then when you get the vape right, the &*%$£ thing leaks! I aim to try rayon at some point, once I find a supplier, based on Anna's rare mention of it

I know you now have the True RTA, and my bet is that will become your firm favourite. But there is an RTA very similar to the Siren RTA - the Cthulhu Hastur MTL RTA and the Cthulhu hastur MTL mini RTA.

The full version has various airflow inserts from teeny tiny tight MTL through to RDL. It is one of the most flavourful RTAs I've used. It is also bulletproof - never leaks, seeps or dry hits.

This box should last you a long while, good price to try it out.

I checked Amazon UK, out of stock. And I hate Amazon anyway.
So then my preferred source, ebay:

erm... no thanks!

But I can get some French looking stuff:

How is this stuff going to fit a 2mm coil, or what do you do to make it fit?

 

[Bigbob2322]

You have to cut off lengths ,if using a 2.5 diameter coil 1/2 of the width should do after rolling in your fingers. Make sure you get the regular ordinre rayon not cotton version. Check out the rayon thread I posted.

Thanks for your help on this I think, seeing as I have a couple of months of cotton to hand, I will put rayon on the back burner for now. I'll keep an eye open for likely rayon sources though.

Strangely, I set off searching for a Hastur! There wasn't one available and came back with a True

Right then, a full strip down of the Siren 2 and wash out to clear out all the stray juice. Tightened the bottom two screws as there was a bit of seepage under there, and jammed the pointy end of a cocktail stick into the outer two air holes. A trim with a Stanley knife to get the sticks flush with the air block, and a SS316L, 7 turn, 2.5mm coil with japanese cotton.

It now draws a little tighter, equivalent to 3 air holes open in the slot, which is where I usually have it anyway. I didn't bother to drill out the centre hole at all, no need. The vape is at least as flavourful as it was with 3 holes, so all that cobblers about the new design was completely wasted, a single central airflow is just fine. It does pop slightly, so I could have got the wicking better, but so far absolutely no sign of leakage from the AFC, or anywhere else. I will report back again if anything changes...

Rayon should help, but you really have to wick that sucker perfectly (and not too tight in the coil) to ensure you get a bit more life out of it.

Closing off the airflow is not going to HELP reduce the need to rewick, I don't think.

I don't use overly sweet or gunky juices in my Sirens No idea why, but you are correct that wicking the Siren V2 can happen more frequently than one would like. It just... It's a huge tank, it is what it is.

I have a non sweet tea juice in one of my Sirens, rayon wicked perfectly (I can just tell these days) it's been the same wick for a couple of refills now,

The Siren is tricky, period. Some juices taste horrible in it, period, some taste so good (to me) caramelized on the wick I have to force myself to rewick it because I like it, even though I know it's burnt.

IDK I guess my other suggestion would be to use a very thin, spaced coil. I think that helps the wick hold up better as well.

Now I REALLY don't think airflow would help.. I run my Sirens wide open but I like a very airy, cool MTL vape.

That's about all I can offer. . You are dealing with a large tank and you really have to get the wicking down perfectly (use rayon) and use the right juices.

Definitely agree however, there is more wicking involved with my Sirens than other tanks, comparatively. To me it's worth it because I love the vape. But the Siren is not known to me for longevity of wicking unless I get EACH and every factor JUST right,

Good luck,

Anna
