fc-2000 porous ceramic wick

[NamVet68]

the other reason i thought it was better was that there is a bigger gap between wick & wick hole then in my other set-ups. thats why i cant wait to try a 1/8 wick in my new ac-9 clone with a 4mm wick hole

Yep, looking forward to getting mine as well. Now that the wick hole on the RSST has been confirmed as being a removable sleeve, it opens up a whole new world of experimentation with wick diameters (I'm sure it's pretty easy to re-insert the bushing to play with various options).

I may drill it out further eventually, but I want to have the option to switch back and forth initially to find out if the fatter wicks are really optimum with everything else being equal.

Now if the dang USPS guy would just show up, I could get busy building wicks & coils - my new hobby...as if I didn't have enough of them already

From my understanding they added a SS sleeve last minute to the RSST to narrow those 4mm down to 3.5 or so. That should be easy to drill out though. I also think most the wicking is coming from juice sliding down the wick than through absorption. That would explain why broken wick stubs work just as well as long as there is juice contact. I know some people are experimenting with making hollow straw-like wicks. I was thinking more wire coverage would give more vapor and was looking forward to the 1/8 and ribbon. Kind of bummer if 3/32 on the AGA like I have now is the best that it gets, the wicking isn't keeping up with me now that I'm using the Legacy, I have to slow down and tilt a lot, yet I have to say the flavor and vapor consistency are just awesome.

So I have three attys running on ceramic, All Elias Hot Wrapped. A 1/8" fishstick on an AGA w/30g at 1.6ohms, a 1/8" FC-2000 on a AGAT2 w/30g at 1.5 ohms and 3/32" FC-2000 on a Dud w/30g at 1.4ohms.

All are broken in with >4ml and all inspected for micro-gaps between coil and wick. Guess which one vapes best?

definatly the 3/32 wick. i know that my set-up w/3/32 is the best overall.

Ding ding ding...we have a winner. Now, please explain.

Ok - gonna throw this at the wall and see if it sticks. Could it be ... the heat sink effect ... gdeal, your wicks are all basically 1.5~ and if you are running them at the same volts/watts (if variable PV) or w/ comparable mech-mods ... then could the thinner ceramic wick let more 'heat' reach the coil and not be wasted warming the stone ... hence more vapor? (got the idea from my sig line)

Although the thinner wick being better pretty much goes against what most folks say about the 1/8" wicking better.

that nut tightening has me thinking that if you had 2 washers, and a nut above & below, then insert wire between washers and tighten nuts. i think that the washers will prevent the wire from turning as you tighten up. i haven tried this yet, but next time i re-do my wick, will give it a go.

Ya know - I'm starting to use the 'pull/stretch' when tightening the pos screw to my advantage. I've noticed the EHW hot wrap really stiffens the wire. And if you have to unwrap a bit at the top of the coil to attach to the pos post, it can leave a little 'kink' in it that's touchy to straighten out and maybe a bit of air gap at the top coil wrap. Today I got risky and wrapped the wire clock-wise around the pos post - tightened the screw just enough to make contact, then fired the PV to warm-up/glow the coil - and tightened the screw to pull/stretch the wire. It kinda worked - but I don't know if I'd risk trying it again.

i dont see how the wick touching the walls is going to impede the flow that much. but if thats the case, once my 1/8th is fully made, ill just grind it slighly where it touches the 1/8th hole i bored out.

havent tried the ribbon yet, but so far i do like the 3/32 wick the best. the 28g and 1/8 wick is very close behind, but i do feel they do dry up a little sooner then the 3/32 wicks.

I'm not sure if its the wicking that is better. The 1/8" doesn't need as much of a tilt. But the vape quality on the 3/32" is noticeable better. Maybe its the greater heat density that is making the difference?

One thing I haven't tried yet is ribbon on the 3/32. That might be interesting, but given the smaller diameter the coils may need to be so close together there might not be any exposed ceramic.

its not that it impedes wicking, its just about airflow. air flow has much to do with vaporization

 

[DeadPerfect]

well if its about air flow, then there should be an issue if you leave the fill screw out on the aga. i always do

wow, good luck with that one. if you can do that, then surely you can hand wrap a 3/32 wick, lol. yes, i agree with the fact that it might not wick better then a 1/8 wick, because holding vertically it doesnt outlast a 1/8 wick, so it must be something else. heat density sounds good, because the 1/8 gets hotter, so it drys up faster, so i guess the 3/32 replentishes faster

i also leave mine out. you know i am just throwing things out there, and really not sure what it is. i think my last opinion is better then the airflow thing. the bigger the wick, the longer it stays hotter, so it drys up the juice faster then the smaller wick, what do you think about that one?

That's what I was saying just a couple posts before yours. So ya think that may be it too.?

 

[DeadPerfect]

someone may eventually just design an extremely porous ceramic if this takes off. a super cloud wicking coil

 

[turspedie]

Makes sense... Might be you are getting more juice vapor with the smaller wick than air heated by wire/stone. Has anybody tried dual 3/32 wicks?

cant really give an opinion. my one 3/32 wick i had working didnt vape that good. my other one broke. i dont think my 4 ohm coil was any good. BTW, i got my pin vice, and yea, its cheaply made. doesnt even have a stopper inside to hold the bits correctly. they move around. gonna plug the center with something

sorry about that, you did say that, yes i agree and do think that is it. you know last month come to think of it i did come to this conclusion but just forgot about it because not to many people were vaping the smaller wicks.

you need the right amount of porousity, if to porous then more fragile. its like the last batch of fc-2000, they are more porous then the first batch. they are always messing around with the configurations of the mixture, trying to find the right mix

Lol...I totally missed that post. Sometimes when you refresh after posting, it skips around.

I compared all of the different wicks at 12 watts, but since I am using 30g on all of them, they should be running at the same wire temp. So it could just be a lower heat sink effect with the 3/32.

It does seem a bit warmer on the first vape, but I am comparing an AGA to a Dud so that might add to the equation here because of the lower air volume in the atty cap.

Edit: scratch that...I need to either up voltage for my higher ohm coil or lower the lower ohm to get a similar wire temp. Ugh...I need to go back and calculate wire temps for each atty...I hate math.

Quick note about these RSST AC9 clone attys. I found that the design also incorporates a thin nylon insulator in the original drilled hole. This apparently serves as an insulator for the smaller metal insert, and meant to be used with mesh. Nice design idea, but obviously not needed with ceramic. Once I drilled out the nylon with a 3/16 bit the hole appears to be pretty dang close to 5mm. Nice for us "grinders".

 

[vapdivrr]

mikeE3, was that you who wrote the post a while back about "watts dont matter its all about wire temp"? i asked because its in your description box. i read that post quite a few times, the first time i didnt quite understand all of it, but months later i totally agreed with it, great post!

It's making more sense to me that this is likely the 'why its better'. I was thinking back to trying some 100+mm solid 500 SS mesh wicks at the same Ωs as thinner ones. And to get a comparable vape on the fat wicks I had to significantly increase the power to the coil. Seems reasonable the same thing is happening with the different ceramic diameters.
