Cool down my RSST Vapor, super intense TH.

[msmalls1982]

I have been vaping for about 8 months now, ventured into rebuildables a few months ago and got a magneto with an RSST from my local store here in CT. They built a stainless wick for me with 28 ga kanthal and it worked great (using PG Hype from Alien Visions). When that started tasting burnt I built my own wick using the same materials, oxidized it properly, even burnt off e-juice 3 times just to keep that metallic flavor down and that wick worked great as well. Now both of these wicks lasted me almost a month as it is my backup PV (I use a provari with a kanger as my primary at work, when on the road, ect).

I recently built another wick and I can't seem to find the right combination to get my RSST working how it was before. The vapor is so hot and the TH is so harsh. Before it was perfect. I prefer a cooler vape without a harsh TH. I have tried using 28ga doing a 3 wrap, a 4 wrap a 5 wrap, I tried 32 ga doing a 5 wrap, ect. I have tried building multiple wicks (some with big channels through the center, others that are almost solid) and I can't seem to figure out what I did the first time to get that cooler vapor that doesn't burn my throat when I am chain vaping.

Any ideas would help, I drilled out the standard 1mm hole to 2mm which helped *a little* but it is still so harsh I have found myself barely using it and it provides much better flavor with my sweeter juices when compared to a Kanger Protank II.

I searched the forum and found a thread similar to this and they indicated that trying a .8 ohm wick was probably the best answer, well I have an ohms meter and that's pretty much where I am right now and the TH is still so hot I can't stand it, feels like I am burning the back of my throat everytime I take a hit.

Any help would be GREATLY appreciated (btw I use 400x400 mesh if that makes a difference, oxidize 3 times, drip in juice and burn juice off 3 times before wrapping my coils).

I cannot help with your specific question, but...

Welcome to the forum.

Someone should be along soon with experience regarding your setup.

 

[Harlen]

If your using high Pg you will get a high Th
With the ss wick I don't find I need to change the wick often just the coil every month or so.
Good luck others may help you more.

 

[msmalls1982]

I use varying liquids, this one happens to be 50/50. I also am getting hard TH with VG liquids too (Gorilla Juice for example). It's definitely not the juice, I am doing something wrong. I think I am going to bring it into the store today and see if they can help me out. Luckily they have great customer service.

What are you using for wick? Cotton, silica etc. and have you tried a micro coil build?

Doesn't apply, he's using a gennie.

Go back and watch a few of Phil Busardo's way of wrapping a wick/coil. That is the best way to find a starting point He even has a vid on setting up the RSST.

It really sounds to me like you are getting hot spots.

 

[steveo9043]

what it sounds like to me is the air hole is not lined up with the wick. Without the direct air coming from the airhole to cool the coil you will get a harsher hit.

 

[msmalls1982]

I am using stainless mesh and my airhole is lined up with the wick, I have been using this RBA for about 3 months and the first 2 wicks worked fine. I am pretty good at wrapping wicks and coils, I use a drill bit that matches the exact hole size for the RSST, I oxidize my mesh before wrapping, then re-oxidize after I wrap it to the correct size and quench it, and then soak juice in it and burn that off 3 times and then wrap the coil (usuaully a 3-4 wrap using 28 ga). It's on a mech mod. Worked perfectly before, got great vapor production and no harsh throat hit but I cannot replicate it for the life of me now. I'm wondering if maybe my wicks are too large? Or maybe burning off the juice is causing that burnt taste as I didn't do that the first 2 times I wrapped and oxidized my wicks? I am honestly at a loss here.

It sounds like hot spots or shorts. Are each wrap glowing uniformly? Do they light up in the middle first and then spread to the outside? That is what they should look like. Have you moved the coils up and down to get rid of the hot spots?

This is why many vapers have given up with SS mesh wicks. They are very finicky. Take some time to move the coils around until every coil is glowing uniformly and begins in the middle

I have been fooling with the RSST rather intensively for the last 5 days. The coolest vape I have found so far is with a micro coil. I started with cotton, but have been trying SS mesh for the last 2 days, an I can't stand it. I am sure if you are experienced with it, it can work amazingly well. However, I am a complete mesh novice and think it tastes awful and is prone to issues if you aren't skilled in working with it.

I'd suggest setting up a cotton auto dripper with a micro coil, see what you think. If you don't like it head back to the shop and get some tips on SS mesh, and please share them with me!

Generally, if my RSST is hitting harshly, I'm either outpacing the wick action of the wick, or I didn't coil it properly and have some hot spots.

Check for hot spots and ensure your coil is glowing evenly.

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.

Given your cap is on right, I am agreeing with the hot spots, the truth is SS is seriously a pain sometimes to work with you can have a perfect working coil and end up with a hotspot out of nowhere add lower gauge wire or ribbon and it gets quite difficult sometimes to manage. It would help a little if we knew if your getting burnt hits or if its just to much TH.

 

[SonHouse]

Well, first problem. You say you want a cool vape and you're using a 0.8 Ohm coil? The resistance of the coil is what limits current flow with a mech. More current = more heat. Try a higher resistance coil. That will reduce the current flow and thence solve the heat issue. I'm guessing the throat hit is a hot spot so follow the suggestions of the previous posters.

I have organic cotton balls and am going to try to use a cotton wick when I get home. As far as micro coils do you just wrap the coils super close together on a drill bit? Don't have much experience with micro coils. I dont want to give up on the SS yet as I had it working fine with mesh before so it must be something else although I do like using cotton wicks too. Much easier, just rip off 1/2 a strand or so after unrolling the ball, twist it, apply some juice and stick it through a pre-attached coil.

What do you do to make your micro coils? And what gauge kanthal are you using?

That may be it, my coils tend to heat up at the top and bottom and then move to the center, not from the center outwards towards the top/bottom. Each wrap is glowing uniformly but definitely not starting at the center. Is there any suggestions as far as pulsing the coil first to achieve this? perhaps before attaching my wick?

Definitely not burnt hits, just harsh TH. I usually do a 4 wrap (which is what i did before and it worked fine) of 28 ga uniformly and evenly spaced. I wrap the coil around the dry wick before adding juice and pulse a couple times to make sure each coil is turning red uniformly but usually the top coil and bottom coils turn red first and then the middle 2 start to turn red. After a few pulses all 4 will light up, then I add my juice and vape, it's just a serious 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: http://imgur.com/2tziUhL


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!

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?

 

[zero7starz]

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.
