Need help with RSST

[HaggardFlorist]

Hi, so i bought a RSST a few days ago and have been having some issues.
I'm using 30AWG Kanthal A1, with a SS mesh wick.
what is happening is that I'm getting hot spots constantly and no matter what i seem to do, nothing is changing.
when preparing the SS wick, I did what I read to do. Folded the edge, Torched and quenched about 8 different times and then saturated it with juice and lit it on fire and I did that about 10 times.
then I put it in the hole and wrapped a 6/5 wrap for the first one. Im using my SVD to measure the resistance and I keep running into an issue where it shows 0.0 ohms. then i have to adjust the screw and it finally reads the ohms but it says 1.0-1.2 and doesnt fire.
then i adjust the distance on the wraps and make sure the leads are touching the contacts and then it shows the resistance as 1.4-1.6ohms.
but the real issue is that it will fire but after a while, it has a really harsh throat hit and taste and i look at the coils and the top 2 and bottom one are burning the juice but the middle ones arent burning at all.
I tried using a cotton wick instead, tried using different sizes of coils, even tried wrapping the coils on a drill bit first until they appear to be perfectly spaced. I read something about using cotton on the outside of the ss wick where the coil sits so i might try that.
the one in the pictures is 2 days old with relatively heavy vaping. probably 1.5-2 tanks full.

any help, tips, or criticism is greatly appreciated.

What grade stainless mesh are you using and what's your pg/vg?

Sent from my GS5.

Sent from my GS5.

its 400 mesh and im not sure what the ratio is, although i believe its more vg than pg, probably 80/20.

NM I can't see

Other than that, looks ok from your pics. I use cotton ball in mine.

To be honest I've never had much luck with mesh and I've tried most types of wicking material. Always had the dry hit problems no matter what grade of mesh or rolling method I used. Not much help I know.

But I now use SS rope on all my Genny type attys now. Started off using the screw method to build a micro coil then used just cotton as a vertical wick. Now I make a 2mm micro coil, take a piece of 1.5mm SS rope cover the top of the wick with a thin cotton sheath and carefully screw it through the coil and into the wick hole. Not had a dry hit since, amazing flavour and vapour production. You can also use hollow ekowool as a sheath if you prefer. Plus it's pretty easy to make your wick, build the coil onto the wick (if you're not using a micro coil) and install it on the RSST.

With the SVD, it won't fire a coil if the resistance is too low. If you want to go for a lower ohm coil, you really need a mech mod. But having said that, I find a decent micro coil with SS rope wick is just as satisfying as a sub-ohm build.

I do have a mech mod, SmokTech Telescope and I have a kick for it but i prefer the SVD as i like VW because i'm constantly adjusting Wattage, sometimes i like a hot vape, sometimes a lighter colder one.
and i'm not too obsessed with sub ohm or cloudchasing. I have a cheaper dual coil dripper that I use for that stuff but I rarely use it. I prefer a tank on the SVD.

but I might give the rope a try. Do you know of any good stores that sell it for a good price?
thanks for the help.

Looks like you're pretty well set up with your kit Must admit I do tend to run my Gennies on regulated mods too, I've found with my Kayfun type attys, I don't need to change the watts so I'll stick with mods for them. But the Gennies seem to perform a lot better with a change in power

the site I use for the SS rope is based in the UK, but they do sell international too, not sure on the postage costs though. Here's the one I use :

Prices are excellent and a high quality product. I get all my SS rope and wire from them.

Glad to help. Hope you manage to get the RRST working well.

Forgot to add, I have drilled out the airhole on mine too, big improvement with airflow. Keep us posted how you get on

Kidney Puncher has supplies as well as a center post rubber for an AGA that works on RSST to stop leaking. Haven't tried it yet.

I believe I've solved my problem.
Used new SS, rolled it on top of a very thin rolled piece of cotton then did a thin layer of cotton on the upper portion where the coil is, rolled the coil while the wick was in place, was not able to test fire as i did not want to dry burn the cotton but got it all set up, tested the resistance(1.4ohms which is good for me) and filled er up with juice/ saturated the wick and bam! works like a champ with no hot spots. althought it seems to be more of a juice hog with the cotton. full tank is almost gone and I filled it 2+/- hours ago.

On a completely different note, have any of you that use the rsst tried to do a dual coil? If so, what modifications did you do? I'm thinking of using the fill hole for a second wick and drilling and threading a hole nearby for the second ground and drilling a new fill hole. Or maybe I'll just buy a dual coil genesis.

 

[Sthur]

I prefer my rsst with a cotton wick and a micro coil running 28 guage at 1.3 ohms. Also drilling the air hole out to 5/64 worked out better.

Glad you figured it out, I will give your idea too a try. I haven't had much luck with ss mesh ever.

 

[PaulBHC]

I just got a second, used, RSST that had the cap drilled for dual coil. He made two vertical coils and twisted cotton ball wick down the two holes. Figuring out the placement and drilling the second hole is the key.

I drilled my first one to 5/64 and it dog whistles to the wife and dogs. Someone recommended chamfer the hole with the next size drill. I did and it didn't help. It was too airy for me so I covered half the hole with clear tape. Haven't tried the dual cap yet.

Glad you got it sorted out. A little bit of cotton can work wonders I find that whenever I use cotton in a build you can almost see the juice going down in the tank, but you can't beat the flavour. I'd still recommend the SS rope method, if you want to try it at some point.

Not tried duals in an RSST, I have used them in a Kayfun though and my aga. It does increase the TH a lot for me as well as vapour production, but seems to give the same level of flavour as a well built single coil - but that's just my experience.

As for drilling out the RSST, I've got one drilled out to 1.5mm and another drilled out to 2mm. To be honest, I prefer the 1.5mm, as the larger one does give more vapour but seems to mute the flavour a little - again just my experience

 

[Chris405]

I have two rsst's and they both perform amazing. I use mesh and flavor is outstanding. just a question about the pics but from what I can see, is there a gap between the mesh and hole? I was always told to have it fill the hole, not to tight but just right....lol

if you want to do a duel coil, just buy one. I have a kraken now and its so much better than my rsst. I have my new prometheus rba on its way here now. should have it tomorrow night to build

My RSST is working great with a 500 mesh wick. I would suggest two things:
Wrap you coil on a 2.4 form and dry fire it on whatever atty you have at hand. Press it together after you release the fire button until it's glowing perfectly from the center out. Then roll your wick so you can pull it through the coil without deforming it; a thick juice helps. Also you can roll it tighter on one end so the initial threading is easier —top side is better. Then cut the bottom end of the wick either diagonally at a very steep angle or do 4 lengthwise cuts about 2~4mm long in a cross (learned that from Todd & PBusardo) it helps tremendously to pull the juice up. Place the wick so it barely touches the bottom or is about 1mm off it.

Last, slide your coil with the wick in place as low as it will go without touching the deck and fix it to the poles. Cut the top of the wick about 4~5mm from the top of the coil. Helps capilar pull and holds more juice.

That works very fine for me on the RSST (got two) and my new Atmomixani Dome clone.

Mesh is not very good tasting initially but improves by the hour and lasts forever.

the problem you are having with your RSST is that it has SS mesh in it
try a 3mm silica wick in the tank to the build bed, lay cotton on top of that and then use a horizontal coil on top of the cotton... works like a charm

Just wondering if you've tried SS rope instead of the silica with the same build, or even Ekowool. The reason I'm asking is I've got loads of SS rope and Ekowool, but very little silica now

I've been using an RSST for quite a long time as my full time vape, and I'm very happy with it. Hot spots have not been a problem for me at all, but I must say I've never quenched a wick I was making. I do torch the mesh well on both sides, do the fold-over, thin, on the end I'm rolling toward, then immerse it in juice and burn that off. I roll my wicks tight, and coil them with 26 kanthal 5/4 for .7 ohm, and I've been wrapping the coil on a plastic Q-tip stick, which has been working well for me.

For the wicks I cut a piece of 400 mesh 3 inches by 1 3/8th inches. Rolled tight this slips into the coil nicely being twisted in the direction it's rolled as it goes in. I work out the hot spots with a dental pic, nudging the coil loops gently until the coil glows uniformly. Hope this helps.
