Fogger V2...WOW

[ScottP]

Yeah... it was left in the upright position. It's weird... I know. Someone else posted a similar experience earlier. Its a sick looking piece. It has potential but I'm done for now. I have math tests to grade. Haha.

Just because I like solving problems, have you tried giving it a little suction when you first pick it up (before firing it) to kind of prime the wicks? It could be that as you vape it, it creates a bit of a vacuum in the tank, and when it's allowed to sit, the pressure equalizes by sucking the juice back out of the wick. I heard someone mention they had to do this with some other device they had....or maybe it was this one...I don't remember.

Alternatively try closing off the air flow when you go to bed, maybe it is allowing the wicks to dry out over night.

 

[ScottP]

I got a little flooding on the ss mesh last night when I refilled it. After I put the fill plug back in and blew out the juice (out the air intake) it was fine. It sat full of juice over night and was not flooded this morning. Just figured I'd report. Not sure if I made a freak ss mesh wick or what, but this is working perfectly. I have another fogger v2 here that I'll be trying some cotton on. I'm going to see how long I can make this ss mesh last. So far it just keeps getting better though. For what its worth, the mesh is trimmed really close to hole, only sticks out a tiny bit and does not touch the glass.

How big of a piece did you cut to roll up? Did you torch the mesh to oxidize it, or did you just build it then work out the hot spots?

First:


Yes it does. I wanted the coil to point UP (away from the grommet). If the build area is a clock, the attachment screws are at 10 o'clock and at 4 o'clock, with the slots at 3 and 9. The only way I can figure to have the coil pointing up is to wrap with your left hand. When I did it my normal way, the coil pointed down.

Now, a quick update on my build, round 2, with a strange result.

Rewicked the microcoil with cotton, but didn't trim so closely, leaving more cotton (maybe 1mm) outside of the well this time.

Added tank (which was a little tricky, as the cotton kept getting pinched in the botton oring), filled about half way, and vaped. Wow again. Working very, very well. Amazing flavor and vapor (as pbusardo says, "A fully saturated vape"). Wicking really well... a little gurgling if I let it sit for 10-15 minutes, but it clears on it's own after the first drag. Much better than my first attempt, where I trimmed the cotton wick too short and ended up with major flooding.

I had to run an errand, so I topped it off and left the PV behind for an hour or so. I wanted to see if that would cause flooding.

When I returned, I expected that I would have a little flooding. Actually, I got a surprise... a horrible dry hit.

Dry hit? It's been soaking in eliquid for an hour... how can it now be DRY?

I do notice that the improvised o-ring I installed under the chimney, which squishes out a bit when I tighten down the chimney, does look sort of close to the inside wall of the tank. Eliquid is getting to the wicks... so not sure if this is just a straw to grab or what. I will go back to the stock oring to rule it in or out, but...

Any ideas on why cotton, soaking in elquid for an hour, would suddenly go dry like this?

I'm determined to find a consistent build on this thing, because the vape is really quite outstanding when it works ("Mouth wants Fogger back"... yep!)

My guess would be possibly too much cotton?? Choking the wick? I keep reading in the micro thread that less is better as cotton expands so much

Take the o ring off its not needed with that amount of cotton filler that is your problem.

How big of a piece did you cut to roll up? Did you torch the mesh to oxidize it, or did you just build it then work out the hot spots?

It was a 2x2 square, torched it, rolled it, torched it, rolled it tighter, put juice on, torched it, then started removing mesh wraps until it fit snug in the channel. Trimmed to about half a mm from chimney which was as close as my cutters could get. Flavor has tappered off but no flooding or burnt dry hits. I do get some metal flavor sometimes though.

I did another microcoil and cotton on my other fogger and it's pretty good. Feels like it's gonna flood but nothing overnight sitting upright. Will report more on this when I get to my desk.

 

[folkphys]

Is no one else still getting intermittent shorts from the bottom screw even with the tiny o-ring in place???

Because I sure am.

 

[timk]

I should add to my previous post that I torched the ss mesh wick one last time right before wrapping the coil. Then checked for hot spots.

Still not loving the idea of cotton in this thing but so far it is the best flavor and vapor production. No dry hits yet and only leaking/flooding was when I took plug out to fill up with more juice. For some reason this causes ss mesh wick to flood also. I left it over night sitting upright with about 3/4 tank and no leaks and no dry hits. Unfortunately I don't have a pic of the important part, how much cotton LOL oops. I used 5/64 drill bit, 10 wraps 30awg kanthal, came out to 3.1ohms. I wanted fairly high resistance for a slower heating coil to give the cotton a chance to do its thing without getting too hot. I also was shooting for a fatter microcoil to get as much cotton in the coil as possible. 5/64 bit does not fit down in the channel by just a hair, so I figured it was close enough to the same size as the channel. I trimmed the cotton to have about 1mm sticking out both sides and put the glass on. The cotton is just barely touching the glass. I think the cotton/microcoil is very dependent on how much cotton which is another reason I don't care for it. On my SVD, 6 watts was the sweet spot on that 3.1ohm coil so I feel pretty safe that I'm not going to roast the cotton. Anyone have any cotton yarn they can try?



Anyway, I am just about done fiddling with this thing. It's kind of frustrating but has been fun. I just received a Reo and nothing is really coming close to the performance of that reomizer 2.0.

A RBA with a squeeze box of juice? Think I found my #1 mod

So far I have tried the following in the Fogger v2:

2mm hollow ekowool - taste was good, vapor production is great, but wick couldn't keep up
1.5mm solid ekowool - taste was good, vapor production is ok, wicked worse than hollow 2mm
ss mesh - taste is ok, vapor production was ok, not convinced it is wicking enough but no dry hits.
microcoil/cotton - taste is amazing when it right, vapor production is out of sight (literally), wicking seams to be good and no leaks as long as it was upright.

Overall I think its a fine unit, but not perfect. I'll consider it a fancy Protank with a disposition. I also think if the channel was opened up like someone else mentioned, a fatter ss mesh wick would be rockin!


EDIT: Cotton setup was laid on its side for about 20 minutes and leaked all over my desk so I'm done with cotton in this thing.

Because I sure am.

I have yet to have a short and I put the oring in the 510 pin. Beginning to wonder if the Foggers I got are different. My glass is much thinner than what Todd's video showed. My gromment doesn't stick up much at all on the bottom. I have only had this on my SVD so not sure if they'd short on my mechs.

I've yet to have a shorting problem, and I didn't add the o-ring.

This thing is a tinkerfest, and I'm with timk in that it needs a perfect build to work well. I'm still running my 0.9 ohm microcoil with cotton. If it sits for a while, I get major dry hits. So, today, I tried something... I closed down the airflow and sucked. I few big 'ole bubbles of air came out of one of the wick slots. I did a few more dry pulls once the air bubbles stopped, then hit the power. Vaped fine, a little flooded but it cleared.

I'm running 50/50 juice, which is on the thick side (seems that not all 50/50 blends are the same viscosity). The clearance between the outside of the atty coil and the inside of the tank at the botton is really tiny on mine. Perhaps there's a bit of a hydrolock forming there... not sure.

It's unfortunate, as when it vapes well, it vapes WELL. I, too, have contemplated the Reo/Reomizer combination... just wish it wasn't so expensive.

The Reo thing was justified because it was my birthday hahaha but ya, cost alot. What sealed the deal for me was resale value of these things. Figured it was low risk.

I agree, Fogger when its right is amazing! The cotton wick for me is not bad, just seems to be needy. The mesh is nothing spectacular but is working well for me.

Got mine today. Fiddled with it for a couple hours before I got the silica wick to work. So far so good! Vapes great! Better flavor than my aga-ts and it's richer flavor. Produces more vapor too. I'm loving it so far.

I put the o ring in around the pin & took out the o ring around the chimney. It sure is picky about how it's set up! I noticed if even one little strand is in threads, it leaks like crazy. I used silica, I think it's 2mm, doubled and cut it as flush as I could with nail clippers. I bought 100 feet of silica a long time ago so I I'm only guessing it's 2mm that I fished out of the drawer of vape stuff. Has to have just the right amount of wick in the channel to work. Too much and dry hits, to little & it floods. I messed with it for hours pulling a tiny strand out at a time till it hit just right. Well... not out but up and out of the channel and left in. I also smushed the wicks inside with my finger, after cutting them as close as I could. Been vaping it for about an hour now and no dry hits or flooding yet. See if it stays that way.

Out of the box all it did was short. Even with the o ring around the pin. The wick inside it was garbage. I'll have to try a ss wick later but for now I'm just happy with how it's working now.

The air flow adjuster is way to loose if you ask me. Less than one full turn is pretty much full open. Other than that, and how picky it is to build, loving it so far.

If it helps any, my adjuster has tightened up as the leaks I've had from various testing has gunked it up. Haven't gave it a real good cleaning since the first cleaning. I agree though, its very easy to un-adjust while holding it. I like airy vapes so its usually just wide open.

Funny, the one thing I did not try was regular silica, just ekowool. The cotton seems to be doing fine as long as it is upright.

 

[Riffy]

Yeah I just leave it open too. I like it airy. I have so much silica from my vivi nova days it was the first thing I tried. It's been gathering dust for a long time now. hehe

 

[ScottP]

Anyone tried actual cotton yarn yet?

 

[Riffy]

Finished the tank, only put in about 1.5 ml after all the messing around. Vapes down to the last drop. I decided to make sure I could reproduce my build so I took it apart, washed it and redid it. Seems to be working the same.

Riffy,

Can you post details of your final build, and any tweaks that you performed?

Guage Wire?
How many wraps?
type and size of wicking material?
O-Ring above the wicks or not? Use original O-Ring?
O-Ring under the 510 connection?
Any modification to the insulator under the coil?

Thanks,
GoW

P.S. My Fogger finally hit the USPS sort facility ... Jeez! 3-4 more days. Ugh!!!!!

 

[Riffy]

32 g wire
5/6 wraps making 2.2 ohms, it's on an evic so around 2 ohms always seems to work best on it. Had it 1.8 ohms but 2.2 made a lot more vape.
I think it's 2mm silica it's not labeled and I've had it for over a year so... I think 2mm
No o-ring above
Yes o-ring under

It's all just stuff I had in a drawer. Did nothing else but cut the silica as close as I could with nail clippers and once I put the chimney top on, I pushed the wick in so it's more flush with my thumb. Have to make sure no strands are in the threading or it'll leak like crazy! I've rebuilt it 4 times now and each time works the same. I tried to do a ss wick and I couldn't get rid of a hot spot both times on the reverse side so I gave up on that idea. Silica seems to work so I'm going to stick with that. I also found it easier to put the coil around the posts starting on the side closest to the center. From the other side it seemed to space it all out to much, more compact this way. Can't think of anything else I did. Takes like only a min to rebuild.

 

[kurtus]

I have had my Fogger for 2 days now, gone through 2 full tanks of dvs blueberry blizzard and to be honest not one leak, gurgle or dry hit with this setup. I am using a 1/16" 28awg kanthal 8 wrap micro coil at .9 ohms. I set it up like this because i use a segelei kick at 10watts or when I want a much hotter vape I remove the kick and go straight battery. It is perfect either way and is wicking great.

The setup is cotton, I use enough so it is a bit tight pulling it through the micro coil, I pull about 3-4mm out of each side of the channels then do the s style pull back into the base leaving the tails flush at the openings. I make sure that the s shape curves down so it touches the base to wick any drips up rather than down into the air tube. Then put the oring back over the channels and screw the funnel back on.

I think that the rubber insulator around the air hole does serve a purpose in that it may be there to stop excess juice that builds on the base from flowing straight down the tube, at least I can see this being an issue if it is removed. The insulator imo is only an issue if you are trying a mesh build because it need to be built low in the channel right where it can burn the silicone, anything else and it can be done as seen in my photos below.

Oh yeah the base section does unscrew for anyone that was wanting to try it or if you want to mod the center insulator. Was just trying to unscrew the fogger from my drawtube by grabbing it just above the adjuster ring, all of a sudden I notice the body is spinning but the base wasn't. Here is the base section off of the fogger and the airflow setup in it. Comes apart at the top of the adjuster ring where the lip is to stop it.



This is a picture of what is left of the fogger after removing the base. You can see the smaller round disc which is the positive connector inside the fogger, if you screw the fogger down too tight onto a mod and the 510 pin is sticking out it will push up into this and may cut through that silicone causing a bad short. Be careful with how tight you screw this onto a mod, the 510 pin is weak and can't handle force.



Here you can see how I setup my coil above the rubber insulator, I use the 1/16 drill bit to hold it flush to the top of the channels, leaves lots of room for dry burning the coil and makes rewicking with cotton easy.



Here is the s styled cotton setup I'm using, the s section comes down onto the base to catch any juice that drops/splashes down, basically a dripper style setup of sorts if that makes sense. Oring goes over then the funnel is screwed on tightish.



And finally some vape porn Notice the work place in the background....yeah they payed for me to mess with my fogger all day lol

 

[ScottP]

Very nice Kurtus!

I just found out mine has finally cleared customs and should arrive sometime next week.

Update...

I vaped my cotton/microcoil build pretty much exclusively yesterday, just to see how it held up, including some heavier-than-normal vaping at the neighborhood poker game last night.

It produced a great vape. Even had a few comments about not being able to see the cards due to the fog... so plenty of vapor being emitted.

Seems like the dry hit issue is only after it sits for a while, which is still weird to me, but easy to resolve (a dry pull or two with the air control closed). Certainly when being vaped regularly, I had no issues with dry hits.

ScottP, I considered yarn as well (I have some pre-boiled P&C #4 in my drawer) from my Vivi Nova days. I may give it a whirl the next time I rewick.
