Cool down my RSST Vapor, super intense TH.

I have tried several different configurations, currently I am using a 28ga kanthal wrapped around a 5/32 drill bit. I think I did 10 wraps and it checks in at 1.8 ohms. Here's a picture of what it looks like, this one could be tighter on the side that's facing the center post, but it works: imgur: the simple image sharer


Check out https://www.youtube.com/watch?v=K1f7vPpEeN8 for a good tutrial on nano coils and how to set up an RSST for auto dripping. I think he may have some micro coil ss mesh tutorials too!

because to me that coil doesn't look like it matches the opening size for the wick which would imply your wick doesn't "fill up" the wick hole? It looks much smaller, from what I have read the hole is around 3.2mm in diameter so you would want to use a drill bit that is as close to 3mm as possible?
 
For a cool, wet vape I've found that:

Using a higher gauge Kanthal helps. I use 34, which is thinner than 32, and does give you a higher resistance.

That being said, I do a 3/4 wrap on my ss mesh wick. Gives me about 2.4 ohm coil. I find 2.4 ohms to vape well for me, gives good vapor production while remaining cool to inhale.

When you're doing things like making a 10 wrap coil, what's going on is the juice is vaping once it hits the first couple coils, then the rest of the coils are making things hot and dry.
If you can dial it back to 3 or 4 you will get a nicer vape.

I'm still working out what ohms to what voltage gives me a vape within the parameters I enjoy, but my cool wet vape is 2.4 ohm coil to about 3.5-3.8 volts.

I think you need to raise your resistance and lower your number of coil wraps. See of that setup helps.

Also! Make sure to torch your Kanthal real good before coiling with it. Helps work out hotspots faster.

Yea I have tried a 5 wrap of 32 and it doesn't produce much vapor, maybe it is because my SS wick is too thick? Going up to 34 with that high of a resistance on a mech mod seems like it won't produce much vapor?

The pbusardo and Zen videos are really good. Something that I tried after I thot that I tried everything--after making your ss mesh wick, with the torching and juice burns--get a candle. The glass memorial candles with the Blessed Virgin stuff on them work great for this--light the candle and hold it diagonal, so that the flame is making soot on the glass. Hold the wick in this flame, and get a really good coating of soot at the area that you are going to wrap coil. Coil and hot spots and juice testing go alot smoother. My Aga S is vaping amazing now, 1.7Ω. at a 4 wrap 32g Kanthal. I hope this helps!!

Do you wrap it with the bit in the RBA? Or do you wrap it on the bit and then torch it and attach it to your RBA so it keeps it's form better and then add the wick? I'm assuming you use SS mesh and just roll it until it fits snugly into the coil?

I coil it on the bit, trying to wrap it as near as possible without overlaping. Then I take it off, put it in some tweezers, torch it, put it back on the drill bit. Drop the drill bit in the wick hole, get the coil lined up and attach the legs to the corresponding posts.

When using mesh I wrap the coils around a slightly larger bit. I have noticed if mesh is rolled very tight it doesn't wick as well.

There's no need for the wick to completely fill the wick hole, that I am aware of. I have had pretty good results and I have never wrapped a coil that large. But I am pretty new to the rsst so I could be wrong. It may be more prone to leaking if tipped over with a narrower wick?

You'll want snug but not too tight. That's the art of all this. I had a real hard time with cotton for the first few days, I used way too much.

Are you oxidizing the .... out of your mesh before and after rolling, is it the same size mesh that you used from the beginning?

    I thought you were working on a Provari, my bad. I'm only just beginning with mechanicals and I don't quite grasp their nuances yet.

    But on any VV mod it should still work.

    If your wick is too thick you would be restricting airflow a lot. That can cause wicking issues giving you harsh hits. If you have a fill hole with a screw try loosening it or removing the screw. Or, make a new wick that's slightly thinner.

    5 wraps can be a little much. Another member mentioned the Zen videos and they are good. Zen recommends a 3 wrap coil for best performance. I like a 3/4.

    The reason I suggested 34g is so you can use less wire and still get a higher resistance. Grab an ohms law calculator it should help you figure all this out.

    Actually, if you are working with a mech mod, what was suggested to me for a wet vape was: 3ohm coil on a AW IMR 18490 which is roughly 5.7 watts. The 18490 battery is a 16.5 amp, keeping in mind that your power will decrease as the battery runs down.

    I actually have another thread going about how I can best translate my vape experience from my VV setup to a hybrid. (Because I really want a hybrid lol.) We have been talking a lot about how to best set up a wet vape on a mechanical setup. It is: http://www.e-cigarette-forum.com/forum/apv-discussion/500580-do-i-really-want-hybrid.html

    Keep at it and you'll get it. Eventually it'll become like riding a bike.

    what was your nicotine strength prior to the rsst, and what is your nicotine strength now?

    you're concerned with heat, and TH.

    Personally, i would tackle the issue in a specific way..

    For heat, i'd check my atomizer resistance and see if it is suitable for the battery im using. If that's within a suitable range, then i'd check my wrap for any hot legs, shorts, and even heat distribution. If that's fine, i'd check to make sure that my wick is saturating correctly. My RSST was built so i can keep my fill plug in with perfect saturation and wicking. Some will argue that you should keep it out. If saturation is fine, then id check my airholes and make sure they're drilled out big enough for the build. A good way to test is to leave the RSST cap partially off and testing it. If the heat AND throat hit is no longer present with extra air coming in, then thats the culprit. If there is still an unenjoyable amount of throat hit, i'd then check the juice and the nicotine strength.

    Airflow is VERY VERY VERY IMPORTANT. Can't stress that enough.

    Its a gennie and he's not on a micro or nano coil, though it can be built that way, Genesis coils generally heat up from top to bottom in the standard build configuration, positive post to negative ground screw. I agree with others you got a hot spot, the coil isn't firing evenly and this is very common with Gennies on SS Mesh wick as you are metal on metal coil to wick config. Sometimes it is not in the coil but a strand of wire in the SS Mesh can cause so much trouble. Using a pick or flat screw driver with the wick dry and no liquid in the tank, slowly pulse fire the coil rotating around, any coil wire hotter (brighter) than the rest of the coil wire there is your hot spot just rake that spot or nudge it out, thats on the coil itself. Now in the wick while pulsing if you see any of the mesh glow rake and pulse, have to work out that short out of the wick. These are the troubles with a Gennie style atty it takes time.

    An alternative to try is where you wrap the coil, first wrap some silica wick, ekowool, organic cotton yarn, cotton ball, or cheese cloth around the SS Mesh first before wrapping the coil, all called hybrid Gennie builds. These builds serve many purposes. One there is no metal to metal contact so once the coil is wrapped and hotspots in the coil are taken care of at rebuild/build, very little maintenance is required nor any mesh trouble shooting is required as the silica/ekowool/cotton wrap around the SS Mesh core is a barrier from the metal to metal contact, though they require needing to rewrap more often, especially the yarn/cotton ball/cheese cloth can't be dry fired. Second, these barrier hybrid builds, the silica/cotton sheath works as a juice storage and holds liquid to decrease dry hits.

    hth a bit.


    I dont necessarily agree to the "genesis coils heat up top to bottom, + post to - post." Mine heats from the middle out. No nano or micro coil. If your theory is correct, try putting your batter inside your mech mod upside down and switch the + and -. Your theory would be correct if it started heating from bottom to top afterwards. Let me know what happens.

    I personally roll the SS around a paperclip, insert it in the RSST, and then wrap the coils with the paperclip still insterted, I wrap very tightly and the paperclip prevents the SS from clamping closed. I also kink the coil between the SS and the negative post with a sharp object, that helps with the hot legs too. At the bottom of the SS I also cut a corner so it looks like this |/

    It'll allow better juice flow
     
    Here's my current RSST setup. Hits like a charm.


    RSST with SS Cable inside 3mm Ekowool wrapped with 28g hotwires. Air holes drilled out. Reads @ .5ohm. I'm use an MNKE 18650 and it hits like a charm. No weird SS mesh taste and cable wicks perfectly to the ekowool. No need to tilt or have the fill plug off. No dry burns at all. I leave it upside down or on its side and it won't leak or spill.

    I do all of that as well, I wrap my coils around my blunt needle and it is a huge hole down the center almost like a straw, it isn't the wicking, it wicks perfectly. It is something to do with the coil and the amount of heat. I'm wondering the the coils are too close? I have a 4 wrap and they are evenly spaced out with the bottom coil close to the bottom of the wick and the top coil close to the very top of the wick. My wick is not "clamped" as when I wrap my coil I keep the needle going through the center of the wick so it doesn't bend or clamp.

    Yea I have been thinking of trying stainless cable with ekowool. Never tried that build before. Is it easy to fit the cable inside the ekowool?
     
    yeah its incredibly easy. definitely a lot easier than dealing with SS mesh. i use a small screwdriver to open the ekowool and torch it while still on the strewdriver. When i take it off after torching, the SS cable slides in easily. Afterwards i pull both ends of the ekowool while the cable is inside in order for it to tighten up...kinda like a chinese finger trap.

    What is your nicotine strength?

    I'm using 18mg. I will give the ekowool with stainless cable a shot. I made a new wick last night, almost like a straw, the mesh is only overlapped 2-3 times so it's a very "thin" wick with a large center hole. Wrapped it 4x with 28ga and it is still burning too hot. It's driving me nuts because this thing vaped perfectly with the exact same mesh and wire before. I'm going to go to the store on saturday and ask them to see if they can help me out.

    18mg on a .8 ohm wrap would be deadly to some. TH would be pretty harsh. What was you resistance when you had your cool vape experience with 18mg.

    Try 3mg nicotine juice. If theres no crazy TH, nicotine strength is the culprit.

    It's not that, I am using the exact same juice I was before when I was getting a nice cool vape without the crucial TH (Alien Visions Hype). Literally using EVERYTHING i used before, same mesh, same kanthal, same juice. It's just something wrong with the setup. I am going to bring it into the store I bought it from and have them help me out because they built the first coil/wick for me and it worked perfectly. Do you wrap the entire cable in ekowool or just from the deck up (where the coil wraps over it?). I have seen a lot of setups with cable where they just wrap it from the deck up or does the ekowool help the wicking process?

    the ekowool is only over the cable above the tank. no ekowool is actually in the tank. My cable is a good size smaller then the rsst wick hole. this allows juice to actually come out. ekowool tends to split and fray. I made mine fray a tiny bit on the bottom so it catches juice coming out of the mesh hole. the ekowool strands acts as a sponge to pick it up. The juice flow stops when the ekowool is fully saturated and it never overflows or spills cause my fill hole is plugged.
