Anyone found a solution fir the burning Vivi Nova grommet issue?

[FigNuts]

Just wrapped some coils with the Kanthal, I think it solved my issue! I'll know for sure by tomorrow.

I have done more coils using 36 awg nichrome. My previous post is in error. The burning issue is not a result of using 36 awg nichrome.

If you think it is the grommet that's causing the issue, MISTerE's diy grommet fix could help.

I have been using the Nova with the rebuilt heads using 32AWG Kanthal, Much better, no burnt taste!

Excellent .... Happy to read the Nova is working for you finally.

So, now I've noticed I have to do about 7-8 wraps to get 2.4 ohms (seems to be the sweet spot for me). I've been using my drill to get near-perfect wraps (tightly coiled).

Is there any benefit to using thinner wire with higher resistance and fewer coils?

Thanks in advance!

Do your coils touch at all? When I wrap 7/8 times the ends touch the side of VN, I find using crochet cotton (very forgiving) helps over come this when I pick at the treads till they form a barrier between the VN wall and coil.
How tightly do you wrap?

The coils are tightly packed, not touching the walls of the atty at all.it sits right in the middle and the coil is about 2mm wide.

Here's one of my latest coils, about 2.4 ohms

Here's a bigger pic.

Holy Cannoli, That's Awesome!!
You Sir are certainly nimble fingered. Wow!

 

[Rellen13]

Wow. No chance of that kind of wrap for me with the sausages I've got for fingers. Nice job.

 

[FigNuts]

Okay, I'll take some pics to show how I wrap like that.

 

[FigNuts]

Okay, so here they are in steps.

I put that together hastily, I have my daughters birthday party today, just wanted to show you guys how I do it.

I don't get how people think that you won't get a little heat on the rubber with clearos like the nova. The resistance wire is clearly touching the rubber grommet...

This is why I'm switching to a rebuildable.

I have an authentic VN 2.5 with zero of those issues.

This is either:
A) Knock-off or defective
B) Just a "V.N. hater thread to advertise "Yeah, I got a ______ instead."
C) Pre-2.5 issues
D) Inexperience

The 2.5 came out relatively quickly.
There is no burning with the grommet. No leaking. Any burnt taste you're getting from the wick/coil is probably due to your inexperience with tanks [no offense] (wrong ohms, wicking issues, juice viscosity, etc.) There shouldn't be any burning at the grommet.

Not to be a fan-boy about it or anything...but this makes zero sense. The OP must have an old version or a cheap knock-off. But he sounds like he knows what "the issue" is (there isn't one BTW). So IDK.

Only thing I can say is already said above: verify the make/model, don't burn the juice. There is no v 2.5 grommet burn issue even while using resistance wire end-to-end.

(BTW...doubt it's B above...but everyone chimes in with one of these posts...snide comments fill the thread rather than useful advice. lol)

My peach tastes like peach, blueberry like BB, Vanilla etc. Works great. Great flavor, intense th, no leaks (one minor one I fixed). Bad QC? IDK either cept mine's working just fine.

whatever you do, don't put icy hot on your grommets

Hum, I'll chime in on this one.
Thinner wire, more resistance however reaches operating status faster then lower resistance wire. Also this will decrease the amount of amp's required to achieve the same thing.
I've found that 5 wraps with 28 guage kanthal ohm's out lower but will kill a battery due to the high amp drain required when firing, same wrap with 34 guage ohm's out higher but requires less amperage to get the same results.
You can also see this when mesuring voltage drop when firing your atomizer, the 28 guage system would drop my 18650 to 3.44v where as the 34 guage would only drop the voltage to 3.68v. It dosen't mean a thing with lower ohms if you have a higher duty cycle and working load, it will result in a faster battery drain and unpleasent vape at the end.

Hope this helps some.

I'm kind of in the middle, I'm using 32AWG Kanthal A1, it's working fine, just was wondering if 7-8 coils was excessive.
