FYI: Smoktech making Genesis-style atty

[Cool_Breeze]

...up and running here with the Smoktech Vivi. 1st run was with a cotton candle wick. This evening I fashioned a u-shaped mesh wick...a little tricky. I think I now understand the 'start with low voltage and work your way up.' Seems okay, but a bit fussy. I'll get better.

Thanks for the all useful messages here.

vape on!

I'd be interested to know how a u wick compares to a standard SS wick, let us know if/when you try a std out to compare them.

 

[Cool_Breeze]

Noe - I probably won't be able to try a single wick since the Vivi has two drilled out wick holes.

Most of us just use one hole and leave the second hole for filling.

 

[Cool_Breeze]

Right...and probably works as well. So far mine doesn't seem to be crazy good, but good none-the-less. I still haven't worked it up much in voltage.

Perhaps I'll try the one-holer if/when I get a 2nd ST Vivi.

I have found with SS wicks a single wick is more efficient than a U wick. The volcanic effect of rising juice from heat seams to be greater thru the center hole of the wick if it is open on the top.

I have try to use it with the existing holes. the former air flow hole will create leaks all the way to the connector the second one if threaded and plugged will be a good filling hole. I shaped my SS wick in tube shape and I roll it in cotton ball until i got a thin layer of cotton on the entire wick I use a syringe through the center of the wick for filling. Mine works for the last 5 days without flaw. In the first hour or so I had a metallic taste that faded after that the flavor is amazing and I have no leaks.

I don't doubt it. Perhaps I can plug my extra hole and give that a try at some point. Thanks for the tip.

 

[BJ43]

No need to plug the extra hole. I have not had any leaking problem with it and it makes a handy fill hole.

Is your wick hole drilled out?

I am at a loss here... After playing with this setup for a couple of hours, I cant get this thing to work right. I get great vapor production, but the TH is off the chart. (..think choke and cough). I have a side hole next to the coil and can also intake through the base under the coil. I have tried the spectrum of combinations from 100% side hole air intake to 100% base air intake. Been through a range of voltages as well. All scenarios have this overwhelming TH. I see big potential here, but I have no idea where to go with this or if I should just scrap it. Any thoughts would be appreciated.

Here is my set up:

U-shape 1/0 cotton wick with 34ga kanthal with silver wire legs pre-measured to give ~2.5 ohms. The original wick holes were opened up so the wick could easily slide in. Wire is wrapped using the paper clip technique, bent into u-shape, then tweak for wire spacing. The juice I am using is a 15mg NET (VG). Here are some pics:

Is your TH 'dry?" ...what voltage?

 

[Suthrnbuckhunter]

I really dont know and I may be WAY off base with this but I noticed a really Harse TH on my 1st try.I took the top off and fired it and I had Hot legs on both sides of the coil i built.I ajusted the coil a few times and it works great now.

Is your TH 'dry?" ...what voltage?

Vapor is good (wet?), The TH is just unusually strong/harsh. I have varied the voltage from 3.7 to 5.2. Around 5 the drip tip is getting fairly warm.

I am comparing it to the same juice in a vivi nova with the same cotton wick at 2.7 ohms. I dont think its the nic level that creating the TH....Very strange

I have NR silver legs going to the coil. I'll play with the coils a bit, maybe some something is going on with the wire underneath the curve. Much appreciated!

Is your wick hole drilled out?

The one for the single wick is drilled at a slant to 3/32. It is the hole next to the neg post. I use high ohm 7/8 wraps and my coils are long, so slanting it eliminates long leg on the pos and allows the end of the wick to goes up into the drip tip hole.

Well if you ain't drying hitting then it must be hitting good.

You may have to reduce your Nicotine Content some more to get where you need to be at. I know when I switch from my Clearo to straight Dripping I have to reduce the Nicotine because it becomes to harsh. Think it is the efficiency of how well the Drip Hits.

Cant wait for my vivi tank and make it genesis style

I count 9/10 wraps and to me that would be more that 2.5 ohms. In your first pic it looks like the center two wraps are touching and that could give a hot spot and cause a harsh hit. What voltage are you using, start low until the wick breaks in, at least a couple of ml at lower voltage. Harsh TH is normally because it is too hot and can be controlled with voltage, but the most important is that it is not shorting and break in the wick properly. They all stink at first. A 2,5 ohm 34g is less than 1.5 inches of wire at 1.8 ohms/in.

BJ43,

You have eagle eyes. I needed to go back to my higher res picture, zoom in 200% and put on my reading glasses to see that. On inspection, you were spot on with the shorts under the curve. I suspected that earlier, but was gun shy on moving the coils around. I was able to get 3.2 ohms with some fixes, but the curve needed to be flattened to eliminate the wire touch. I lost coil shape with too much wire adjusting trying get the curve back. (I need to develop my coil skills...) I would have attached a picture, but things got a little ugly....

So I am now onto round 2 with a bit more care and proper break-in. Thanks.
