#500 SS Mesh

[mwa102464]

Agree with all you say and sorry if i sounded argumentative just stating my reason for this thread and yes most do use 3/4 wraps and most that I read, if the went to more wraps the problem was poor wicking and dry hits, that was what I was looking to improve, taste is another subject.

Well like I said,, wicking and capillary action always seems to have room for improvement You may end up liking a wicking system I have been working on for some time now,,, my final solid porous ceramic wicks are being made for me as we speak,, They loOk something like the picture but not exactly like it BJ there's a little something else being done to them.

So many parameters all to get satisfaction. I wrap for max vaper production and tweak for taste, but I am boring I only use basically one juice and it is 100% vg with a little menthol.

Love it, put me on your list.

BJ43,,, that's another thing,,, are you only using these cheaper VV Nova and those other cheaper Smok tanks that your modding to a Genesis unit ??? If so this is part of the difference here,,, do you have and are you running a high quality Genesis unit ?Zen, Cobra, Orion, any of these ? because they do make a difference believe it or not, some of these newer Genesis units are really much better these days I find. I have had so many dam Genesis units and never found one I liked until most recently with these newer ones that are out now.

I have 5 authentic Lines, GTUS, 2 Bulli A2, Bulli tank, Penny, What is your favorite.

Yup we differ there too, I must have 35 Mods set up at any given time with a different set up and juice in each one BJ43,, this is what I'm vaping on tonight

Your already on it my man, been done for a while,,, you and a few others.

 

[mwa102464]

BJ,, My lines are in hibernation at the moment, well I do have one set up with Silica running in the tank up to the coil wick with cotton around the silica at the coil,,, but the lines just dont compare to some of the newer gear

BJ if you are looking for CGR's still, Smartvapes and Amazon both have good prices too, not sure about the paypal requirement at either though. Do you still trust Amazon with your CC?

 

[emonty]

BJ, send me your addy and I will send you a 100 mm wick that fits a 2.5 mm hole.

I've been wondering when those are going to be released into the wild

Been searching and searching for someone who's trying to source a solution to the solid ceramic wick.
Seems like it could be the answer to short hell. I'm still waiting for my new kanthal to arrive to try 100 plus mm in the DID, but solid porous ceramic, could be heaven.
What do I have to do to get on that list
ps. WOW what a collection of beautiful gennys.

 

[the ob]

Has anyone figured out the perfect mm width for the cobra?

I know Emory said 60 mm before but I feel like it could handle more

 

[emonty]

non oxidized the Cobra can take ~100mm, I only oxidized the part where the coil is wrapped

 

[otrem]

i dnt hav cobra, whats the wick hole dia?

I too was on the less coils train with mwa (only on the geny set ups). Seemed to give me better vapor and flavor. FWIW on the geny set ups I need 10-12 watts. This seemed to work best with 1.3-1.5 ohms (2 wraps of 32 and 3 wraps of 32 on the Zen and DID respectively)

On other units though, more coils, as many as possible, work better for me. And I have no desire to go over 9-10 watts max.

I enjoy long drags, seems like no matter how much vapor a set up is pumping out my pipes can keep up, and long drags at 12 watts and up for me seems to result on scorching juice usually

But when I got my 30 awg kanthal in I set up a six wrap coil on the DID and honestly its been my favorite so far. Still fairly low resistance (I think it was 1.6) but just all around a touch better for me.

Again, variables. I suspect my greater success with less coils may have been due to the fact that I've been slowly learning how to deal with mesh over the past few months, and its easier to botch an 8 coil set up than it is a 2-3 coil set up. Not just more places to get shorts, but also more places to get coils that are seeing too much air, etc. The latter point for me has been the deal breaker. I'm not happy with my set ups unless all my coils are touching the mesh and are as tight as possible just short of cutting into it and shorting out. Otherwise my 15 second vertical tests fail as the looser coils get too hot, and I end up with harsh hits during vaping.

I did have a BS theory that less coils worked better because a more concentrated heating area would have an easier time of overcoming the heat sink and wicking of the mesh. I really don't know if this is right, probably not.

Soon i'll be home with all my toys, can't wait to start breaking shtie and getting scolded by the woman for fogging out the house

First of all BJ, what a fantastic thread. Just finished reading it all and what a huge advancement you have made. I'm pretty new to SS mesh and haven't been a fan of tilting. Although I have some #500 mesh on the way all I had lying around was some #325. From your earlier posts on the possibility of rolling on the bias I thought I'd give it a try as you hadn't gone ahead with the tests. I rolled a 70mm wick from the #325 and jammed it into my Orion V2.1 which I think has a 2.5mm hole. I don't have any VV devices as I usually use a kick. However it doesn't fit in the Orion so I started with a 5 wrap coil from 32awg on a semi charged 18650 at about 3.7v. As the Orion is a hybrid I can't seem to get an accurate measure of the ohm's from the unit (can't be bothered removing and testing the wire), but I'm guessing the wattage would be between 7-8. I'm using 50/50 PG/VG. As you can see in the video below, capillary action is in effect. Not huge amounts of vapor, hence I've come down to 4 wraps since, but you can see that with the Mod standing vertically, although it can't keep up completely, capillary action is functioning. The top coil starts to get red hot after a little while, but after a break of 5 seconds or so it's soaked again. By the third heating it really sucks up some juice. The wick is absolutely jammed into the wick hole and I'm vaping it at an angle of around 5 o'clock and it's keeping up with me. So your thoughts on the possibility of creating smaller holes in the mesh due to rolling on the bias has worked. Not as effective as the #500 no doubt, but it's so much nicer than having to rely on gravity. I have some 28awg and 30awg on the way too to get the wattage up in my hybrids that don't fit the kick. Many thank you's for all your hard work, and to everyone else that has contributed to this wonderful thread.

Just to throw in here...and this is my journeymen electrician ticket taking here...there's 3 different types of physics at play here...fluid dynamics, thermal dynamics and basic electromagnetism (broad term for electron flow)...I know diddly about the first 2 but I do know electron flow. Now I'm not supporting any one position here but the fact is we want watts, watts = heat, I think that's a common desire with all of us right?...so with a given resistance, say 2 ohms (for simple math, also, lets ignore v drop, hot/cold r changes, etc...)...4v applied to 2 ohms will produce a 2 amp current, 2A x 4V = 8W...that same 8W can be achieved with 5v applied to a 3 ohm coil...but you current has dropped to 1.7A...in the electrical world, you never want to lower your load resistance to achieve higher wattage, high current is hard on equipment, more expensive because conductors have to be bigger, require more robust switching, etc, etc...this is one of the reasons why the high tension wires overhead run at upwards of 500,000V, now super high V also has it's issues but that's another story...where this starts to blur into the other 2 physics is, a 3 ohm coil will cover more wick area than a 2 ohm coil (provided the same size Kanthal is used)...that same 8W has to heat a larger area of wick, so even though 8W is 8W...thermal dynamics kicks in and you will need to overcome that...that larger area may need 9.12W (outta my a_s) so you need to adjust your V up to 5.2V or so, which is fine, again, it's always better to adjust your potential (V) up than decrease the resistance of your load (which raises current, A).

...I would like to hypothesis here..., again my Fluid Dynamics and Thermal Dynamics are a little rusty but can we safely assume that "all" of our exposed wick contains juice?, I think so...wouldn't we want to spread our heat over the largest part of that reserve as possible in the spirit of efficiency?, again, I would think so

...I started out saying I'm not really supporting any one position here but now that I think of it, I guess I am...BJ's on the right track here, even though I don't necessarily follow the above (because I also like the simplicity of a single batt/mech mod), I think the best way to dial in your particular vaping experience is adjusting potential, not the load. This can be argued ad nauseum but at the end of the day ohm's law is what it is and high V is always, "always" better than high A....and an incremental increase/decrease of V is a much more finite adjustment...current is the kettle drums, V is the string section

anyone notice the price of the mesh just went up? It said they were selling so much, that instead of the scrappy ends, they were now selling from the industrial rolls.

I wonder what happened?

one other question. for those using 28g and 30g. How do you get six wraps or more on the mesh? I noticed when I tried the 28g that because it is so thick, that wrapping it on the device was much more difficult. Do you wrap it off the device and then put it back on?

I notice the same crap happens with kanthal as well...suppliers starve the market a bit every so often, then bam, it's back on ebay at double the price, we're all like "finally!", suck it up and pay... rinse and repeat...we're our own worst enemy

I wrap it on the device and just pull harder to get it tighter, with the fat wicks you can pull quite hard and not kink the wick. I am using 100mm wick 400 mesh (still waiting for my 500) 4 wraps of Kanthal A1 28awg and getting about 0.8- 0.9 ohms.
