Haven't used the 3 lb version, but is it thick enough to split in thirds? That could be a bonus
All I've seen is the 3lb. For 2.5mm coils, thirds is just right.
Is it normal to have to run lower watts on the same build with rayon vs cotton? I just re-wicked a build (primed it, let it sit a while) and I ended up getting some burnt hits on longer button presses. I am using a 0.26 ohm dual coil build in a Griffin and was running it around 45 watts with cotton but have had to turn it down to 42.5w and finally 40.0w to avoid burnt tasting hits. I haven't checked the wicks since I wicked it but I may have scorched it and am considering wicking it again and starting at a much lower wattage to let the rayon break in a bit before I push it back up to 40 (and hopefully higher) watts.
My apologies if it has already been addressed in this or the previous thread. I just searched for a rayon thread and jumped in on the last 2 pages.

Most likely, you don't have enough wick in the coil. The burnt hit you are getting is because the rayon has started to collapse and pull away from the inside of the coil. You need a lot more density inside the coil than you did with cotton. If wicked properly, we usually run higher wattage than what we used with cotton.
Check the first page of this thread. Jeremy did a very nice tutorial in the first several posts that should get you going in the right direction.
Thanks.
Yeah because your not using near enough rayon. Always check the wick if you have any problem. It should remain in contact miact with the coil.. I'll have to make a video that shows this simple test but there are examples in post 4 or 5 of the thread...
make sure you also thin at least half the tail thickness.

Thanks guys, will open up the first page and read it in detail when I have time later today or tomorrow before I re-wick that tank.
Use so much rayon that you need to "screw it" (which tightens it) so it fits into your coil. You know it's the right amount if it BARELY fits and when the rayon squeeks when you turn/screw it inside the coil. That's what I read.
the order placed on July20 was in my hands Monday Aug 1st. the order I placed with FT on July 30 is sitting in Chicago......wow,, that was fast.
I use these forceps Dissecting Forceps - Curved Fine Point - DR Instruments to hold the coil in place while I pull the rayon through.
They also come in handy for holding small screws, picking up cut coil pieces, etc., etc., etc. And they're cheap!

That works, I usually pull side to side.. you'll feel or hear it while pulling it though too. Once it starts to squeak pull one coil width through and that's usually good.
At about 2minutes in this video you can hear the squeak we are talking about.. I went a little extra tight so it was audible.
I can't hear the squeak... I have tinnitus, and the sound of crickets in my head drowns out that frequency. Fortunately, I can definitely feel it.
That's probably closer to the correct amount for shorter break-in times. For me, if it's barely audible, but you can feel it in your fingertips, then there is almost no break in time. If it is super tight and you can clearly hear it, it's probably gonna take a little while to get it completely broken in.
An accurate assessment kazziel!
Great explanation. Should have said that in the op..

It seems to me that smaller coils take less "tight" than larger ones.
Nah, because I kinda agree with Paul, too. It seems to be a little different depending on coil diameter, and also wire gauge. When I do 3mm coils with 24g, I make the wick a little tighter than I do on 1.5-2mm coils with 28-30g. I don't know why, but larger coils with heavier gauge wire seems to need a bit more wick density. My guess is that it has to do with the extra heat... I think the extra heat collapses the rayon more. I have no science to back that up, though...
Just a warning, I'm gonna go

Heaven Gifts is running a contest and giving away a bunch of prizes. There are about two weeks left in the contest, so if anyone is interested, go check it out. The OP gives ya all the rules and stuff, but basically, you can pick pretty much any item from their website and win whatever you want. And everybody gets two entries per round. Currently the contest is in Round 7.

It's the size of the wire. The thickness gives a taller profile and needs a tighter wick so it feeds up the taller wire better. That adds to the already increased gunking from heat retention.
But as far as break in and longevity your right
That makes sense. I hadn't really put much thought into why it needed to be tighter in my bigger coils, just that it did need to be tighter. Thanks, man!
If you look at the coil across the top from the side you can see the wires profile or height if your using a spaced coil. Looking from the side with a spaced coil you can also see if you have any wick that isn't contacting each coil.
With say 32 it's buried in the wick and soaked, with 26 the juice has a longer distance to travel to the top of the wire to soak the whole thing.

Long time I don't contribute anything (meaningful) to the thread... snapped some pics while rebuilding a Wotofo Serpent Mini, it may help someone looking for how to trim rayon tails.
Initial wicking, rayon fluffed out
Diagonal cut
Wet it for further shaping
Final vertical cut, atom base as a reference guide
Good to go
Yeah, not a perfect execution, but you get the idea... [emoji57]
Note: the 'final cut' is what makes the tails as thin as you want them to be; it's vertical in this case because the serpent mini sports huge channels, for smaller channels (SXK Wine comes to mind) do it more diagonally.
