New Cobra: 2 Basic Mesh Questions

[Ansah]

I finally have it working, I think, but not sure how I got there...

1) Does 500 SS mesh have a "grain"? I've been rolling wicks parallel to what looks like horizontal lines, but I'm not sure if it's just how I see the 12x12 sheet in certain light. At any rate, is there a "right" orientation and a "wrong" orientation for rolling the mesh?

2) What's the best size SS cut for depth? I know I want right around 40mm for length, but not sure how fat/tight it should be. My working wick currently on the Cobra is rolled with 45mm of material, but I suspect this is too large. For now, I do want to continue to use a paperclip, since I've tried and have had poor luck rolling wicks without a center "chimney" hole.

Any thoughts would be welcome. I spent about 5 hours trying to get a smooth setup. It always looks so easy on the videos...

The Cobra truly is a stellar build, made of high-quality components. The difference between this and the $20 clones is obvious, but I haven't yet had that ah-ha! moment that comes from knowing that I've figured out how to assemble it in a way that is repeatable.

Yes, the mesh definitely has a grain. I don't know how much difference it makes; but I always roll so that the grain is lengthwise. As for width, it's a matter of preference. I've seen and heard of people using anywhere from 75mm to 25mm. There are proponents of super tight wicks, and those who advocate "straw like" wicks. 45mm should give you a good wick. As you experiment with different widths, just keep notes of what you find works best for you.

Thanks Rule. I tried an improvised variant of the Petar K method, but used the Allen wrench that came with the Cobra (vape Dudes sent me a screwdriver style wrench, the stem is not hexed), rolling a 40mm x 30mm 500 SS with the paperclip, and got a nice even glow on the first try. I did oxidize, but didn't go crazy with it or do any kind of a juice burn.

It's seems to be working fine. I'm speculating that the smaller wick density improves both the wicking and the airflow, and I'm getting nice flavor without the metallic taste I had before. I'm still not exactly sure what these Gennys are supposed to vape like, even if perfect. Stable 2.4 res set at 4.4v... I think I'll leave it alone for a few days and just vape.

I've been experimenting lately with less dense wicks myself. I was building my wicks bone crushingly tight for a while. But I was noticing that the more dense the wick, the more watts are required, because the denser the wick, the greater heat sink it is.

Seems you are getting the setup side of things going, so just keep experimenting on that
I just wanted to chime in that 4.4volts at 2.4 ohms is about 8 watts. I use most clearos and cartos and such at around 8-9 watts, but for some reason i find that gennys seem to shine on a higher wattage. I haven't gone up to the wattages that some seem to like, but I do enjoy my cobra at around 12-13 watts. Try bumping up the voltage and see how you like it

with mesh it may take a wick or two till its perfectly vaping, but usually with my juice when i start getting thick clouds not so much huge just thick, and nice texture and yummy taste i feel it good to go. i do notice some of my wicks seem to work better the next day in the cobra.
if you can feel the nic and get a nice lump in the throat first few hits its working great.
as i like to vary and experiment with wicks usually in the 40 to 50 mm range for width is fine.

i run 500 with a 32g coil around 2-ish ohms in the range of 4v. somewhere.

Interesting, thanks. Have you seen the power chart?

I've been assuming that I need to move everything at about 8w... Does the Genny setup mean we can throw this chart out the window, because it's more robust than an Ego or whatever?

Your set up will vape ok at 8w; but you may find yourself bumping the watts up a bit. You can push genesis set ups a lot harder than Vivis, Clearos, etc. I used to vape those at ~7w or so. I vape my gennys anywhere between 9w and 12w.

I have seen the chart, and whenever i use cartos or clearos it seems to hold true - i do stay at 8-9 watts. The gennys just seems to be a different beast. I don't expect every kind of juice to be able to handle the higher wattage, but it has been working well for me so far.
