I have spend hours trying different setups, yes it is trial and error and very difficult to pin point one setup being great for all genies. I have hellfire's, Orion's, cobra's zenisis, bliss rba's and each has it's own characteristics and different ways to achieve the optimal configuration. I tend to get frustrated at times but as I speak I have for each one finally a perfect working setup. I don't know if next time around when I have to change the wick and or coil it will work for 100% again but I have faith it will as I know it can work. So for all out there who give up, continue and you will nail it. Some of the setups start shining after a few tanks, some right away and I cannot figure out why that is. It is very difficult to understand why sometimes it totally does not work but for sure it has to do with oxidation of the wick. The variables are very closely related and if they match you have success, if one of them is off, it sucks.
I repeat: This thread was intended to prove which wick mesh, wicks best, most and fastest replacement of juice vaped. Had nothing to do with taste. I would probably choke on emony's setup and not get any satisfaction on Quigs, taste and TH are not parameters for a wicking lab test. Don't know any lab test for taste or TH, that is up to each individual. I am interested if any one is getting dry hits with a 500 tightly rolled wick as that is the only parameter that would contradict my lab tests. Some one mentioned starting a thread for best wick coil for each different RBA and I think that is a good idea. Would probably prove there isn't a best for any.
If anybody has a small piece of 500 mesh they would be willing to part with so I can try this stuff please PM me. I can't find it anywhere except the UK and I want to try it before I commit to a large sheet.
I got some for ya. Send me your address.
Emonty: Is is possible to "over oxidize" a wick?
nope, but good test!Last time I put the wick + coil from myDID up side down in a ultra sonic batch, the water turned brown and accumulated dirt came loose from the coil. After that I washed with water and dry burn.
Have to repeat this cleaning method to see if it's really significantly removes accumulated carbon dirt on the coil and that I don't have to adjust any short's.
Anybody have experience with this method?
It is the rapid cooling down of the stainless by quenching in water that tempers it, making it harder, but very brittle.
I have made springs in this way before, using normal mild steel wire.
Has anyone tried oxidizing the SS without quenching it? Just give it a little time to cool off normally before reheating it.
If you let the temperature go down by itself, it should stay flexible. (I might be wrong, but I think it's referred to as annealing).
OTOH, I think the thermal shock of quenching it in water roughens the steel surface, which should aid wicking.
I am no kind of expert in this field, so these are just my hypotheses based on observation.
Quig try crimping the top of wick so it closes even a small center hole. Put the coil as high as you can on the wick will reduce the backflow from gravity of the juice that is higher then the coil and flows back down after you vape the juice underneath it.
BJ, concerning your question and the reason of this thread: I am still breaking in my #500 mesh wicks and do sometimes get dry hits if I don't tilt the PV enough. That being said only on setups that have no hole in the wick or that have very tiny one's. On one setup where there is actually a good size hole in the wick it appears to wick better, but I am not 100% sure yet. Going to run the setups that I made for a couple more days and will let you know my results. Also I am still doubting if the #500 mesh wick actually has a better capillary action when used for the I would say smaller wicks (60 mm or thinner) being used in setups with smaller wick holes. All my liquids are 30%VG and I am running them all on pretty high power as that might be an issue by itself as the liquid has to go up very very fast but I also only take 1 or two second hits and I don't chain vape...Still not sure if really the #500 actually wicks better in "real life" then the #400 and if a solid wick is better then a wick with a bigger hole......

Quigs I was overjoyed with my Z Atty P, but I bought the 'stiff draw cap' and my joy increased
If you're so inclined I'm sure you could epoxy or solder the hole and re drill something more narrow, or something to that effect
Good question. I don't know if I would call it over oxidizing but what I do know is that if you torch the wick too much, it becomes brittle. Not only will if fall apart sooner but it looks like the oxidation actually does not hold: small pieces break off because of the heat generated, exposing non oxidized parts of the wick (the mesh actually breaks) and with that creating "hot spots".
I read earlier that BJ43 had significantly better wicking in a test on pre-rolled oxidized wick because the holes are closed down slightly. This makes sense based upon capillary action.

Apparently his oxidation technique is well honed. I ask the question earlier about over-oxidation because I have looked at dozen or so videos of people oxidizing their wicks and they run the gamut. Some of these guys are doing a 4-6x torch/quenches, then burning juice multiple times, etc. These aggressive oxidation technique are probable overkill for finer grade meshes and may be a reason why people are not seeing differences in tightly rolled #500 mesh (or #400 mesh as well). They are essentially choking off their wick with oxidation.
Hopefully BJ can chime in here as well and perhaps share his oxidation technique for #500 mesh?![]()
Rolled a 325 and a 400 tight 70mm 11 in long to compare with the above. Left the three vertical for two hours in two inches of waterOn my lab test a 70mm 500 tight wick the length of a sheet (11in) placed in 2 in if water maxed out at 3.25 inches above the water line. .
