vivi nova rebuilding questions

[vegan]

1. If using cotton wicks, it seems once the coil gets gunked, it's a goner. Have you found this to be true? I tried soaking a few of my rebuilds in distilled water (after 2 or 3 days use) and when I go to use them, they are more are less as poorly functioning as they were before soaking. So, I was wondering, if I soak them everyday (in theory before they get too dirty), do you think they'd last longer? Or is there a more durable cotton alternative (not ss mesh) that is suitable for repeated use?

2. The rubber grommet where the "legs" go will inevitably get worn out. It seems to be the only non-durable piece besides the wick/coil. Does anyone know of a hardware store or online source for getting grommets that will work as replacements when these start breaking apart?

Yeah, I understand, the vivis are cheap, as are the heads, etc, but I'm thinking in terms of potential FDA legislation and want to be able to be self-sufficient as much as possible. Besides, why buy new gear if I can just replace 20 cent pieces whenever necessary?

Cotton burns very easy. I suggest useing your nova at a lower voltage/wattage setting.
Once cotton gets burnt even a little, its no good anymore.
Also what size in Dia is your wick, if too thick you could be chokeing the wick and not getting enough of juice.
Also try tilting your device at 45 degress angle when puffing more times then your doing now.
If your makeing your coils, your saving a lot getting 2 or 3 days on a nova sounds good to me!

The coils can be easily cleaned...remove your wick and dry fire them. If your device has no short protection BE CAREFUL not to touch that coil to the insides!

i tried cotton wicks for awhile and mesh also for the vivi's in the end i just went back to using silica wicks i prefer to use a few thin wicks to one large one as they seem to last longer before clogging up and you can dry burn them to get them to near new condition, as far as the rubber gromit i haven't had one go bad yet but my buddy uses some rubber tubing from a slingshot you can get at any walmart one band will get you like 60 or more gromits.

Yeah, I use a VV ego type battery.. I always start at 3.2v until I start getting a proper hit. I'm using Norpro cotton twine recommended on a Youtube tuturial. It appears to be the same diameter as the stock 1.8ohm wick. However, I do have to pinch it a little bit to get it in the head. But I also unravel the ends to help with wicking. I always puff at a 45 degree naturally as far as I can tell. I mean they hit great but like all wicks they get dirty. I also use all VG mix which probably magnifies the gunk.

I guess 2 or 3 days isn't bad, but I'd get a week w/ silica. I wonder if the bamboo/hemp wicks are better.

Yeah, no protection so don't wanna risk it. Plus, once I remove the wick from the coil, it's a b-tch to feed another wick thru and then I have short legs I have to feed back through the head which isn't fun. May as well just start from scratch.

Yeah, I just don't like that whole silicosis thought, even if the risk is minimal. Yeah, I'm one of those worrier types. I don't even like the aluminum on the Kanthal.

Thanks for the grommet tip. I guess I'll have to just rummage until I find something that works. I'd like to have about 5 ft of it to match my hundreds of feet of wick and coil material.

I have yet to wind a coil for my Vivi Nova, but I like the "wind it on the wick" method I've seen on YouTube better than the "feed it over the wick after you wind it" method. You can always loosen the coils if you wind them too tight on the wick itself.

I've been able to recycle my heads several times by cleaning them under a hot water spigot in the kitchen sink. I have one of those mesh drain filters over the sink drain to catch anything I drop and keep it out of the garbage disposal.

I've watched the coil winding videos and it looks pretty straightforward to me. At this point, I'm still using and recycling the 8 heads I ordered with my first Vivi Nova. Eventually, I will jump in and wind.

 

[vegan]

Yeah, it's super easy for me now. I just started doing it about two weeks ago. With 25 bucks I have enough material to probably rebuild at least a hundred times. I just wrap it directly on the coil. I just know that after, say 20 rebuilds, those grommets on the bottom aren't gonna hold up to being pulled out and smashed back in over and over.

Cotton is hard to clean once it gunks up, silica can be dry burned many times and be like new but cotton can't handle dry burns. If you're using cotton I'd just spend the bucks for a few extra heads then rewick and coil as needed once a week to save time, in between just screw one off and a new one on.

Anyone know the order of design change in the Vivi Nova wicks? My first one came with a large single rope wick. The one I got from an order the other day has 4 wicks and so do the replacements I ordered with it. Is the 4 wick arrangement supposed to be newer and better? I got better vapes when the juice is low in the tube from the single large wick than the one with 4 wicks.

Just wondering. Both are supposed to be V2.5 Vision Vivi Nova Minis.

 

[jazon1]

if you look on the side of them there will be alittle print on them in white with the ohms rating the ones with a thick wick are higher ohms coils so you will nead to use higher voltage the ones with the 4 wicks work better for me but are 1.6-1.8 ohms so i use them around 4V or 6.5 watts.

I use 100% cotton balls I picked up from Walgreens. Just pinch a little off a ball, roll it into a wick shape. With these, I just take out the head, rinse with some warm water, squeeze the cotton so it's small again, pull it out of the coil, dry burn the coil a bit to clean it, then roll up a new wick real quick and slide it back in. Throw in some juice, let it soak, and you're back in business.

I guess 2 or 3 days isn't bad, but I'd get a week w/ silica. I wonder if the bamboo/hemp wicks are better.

When we switch from silica wicks to cotton wicks we change how the nova was designed to be used.
Soon as we change/mod any part of a nova something will change.
When we mod the nova we are trying to increase wicking or air flow which means we want more flavor or vapor, modding will use up more juice.

I have found that more juice less burns less coil changes, cost evens outs.

I don't have the vvn but I recoil/rewick my reduxes all the time. (same type head). I install the coil so that the negative leg is against the slots. It usually shorts out there but that's what I want. I pull my cotton wick in from the positive side toward the negative and that insures the coil stays over to that side. When I replace the wick, I can see which side of the coil is up against the metal and I know that's the negative side, so I can pull the wick out in the same direction. I always check with a meter after building or rewicking to insure that I don't have a short or open.

I also use a main wick with another helper wick over the top, similar to this setup. (I think my wicks are smaller though.)

Everywhere I look I see 4 rope heads for sale, or at least the pictures are the same for 2.4 and 2.8 and 3 ohm heads. Some sites say that the actual shipped product may vary in appearance. What I have found is that my heads that originally came with single ropes vape farther down into the tank than my new ones with 4 ropes. I know it's not my imagination. Half a tank on the 4 rope heads starts to taste like a slightly dry wick. That doesn't happen until the level is almost down to the bottom metal cap in the single rope wicks.

You'd think that 4 ropes would expose more area to juice. I guess the difference is in the coil contact on a single versus a 4 rope wire wrap around the coil.

I saw a forum post about SS wicking a ViVi nova so I gave that a shot. I must say this is the best flavor I have ever gotten out of any atty and that includes dripping, genesis and other rebuilds have not even been close to this taste. Was way easier then the genny setup too. The SS should last damn near forever not like the cotton ball wicks I had to replace every 5-6 tanks. I cant

My experience was the complete opposite. I get much better wicking and flavor with cotton than I did with #400 mesh, and was easier to rebuild. You're right in that it's a pain to clean and change flavors with cotton though. Another thing I noticed with SS was it would scratch my tubes, which I don't care for either. I guess different strokes for different folks.

Can't agree with better flavor over the genesis though. I get much more flavor out of my AGA-T+ with 28awg @ 1 ohm on a mechanical than I ever have with the Vivi Novas or silica based drippers on VV/VW devices.

I filled up a carto after vaping the Vision Vivi Nova mini for a few weeks. I expected much better flavor from the carto, but it was a toss-up. These are the SVC CloudMaker cartos that suck up juice as fast as you push it into the condom. They are great cartos, but the Vivi Nova actually produces equal vapor and flavor with fewer maintenance and filling hassles.

I guess the 4 wick models need some time to break in before performing at peak. Mine seem to be iffy on the wicking when new and better once I vape them for a while. I get farther down into the tank before I begin to notice flavor dropoff.
