Tfv4 help.

[jahines1]

Hay all. I know this subject has been beat into the ground but in really having a hard time figuring out what the problem is. Ive tried wicking every way on this thing as I can find but still getting dry hits. It works fine for the first four or five hits but then starts to go dry. Anyone else rin into the problem where it starts out fine but cant keep up?

What diameter coil? What ohms? What watts? Got pics?

I'm just using the stock coil that came installed on the single rba deck. Been trying to run it around 40w. Not site on the ohms. Had to pull it out and put in the quad coil to make it through work.

If you're blocking the juice channels with your wick, the juice can't get to the coil. I had a bit of trouble with that too. My Tobeco tanks need much more wick in the channels and it threw me off. The wick really just needs to rest over the channels.

 

[jahines1]

This last build that failed didn't have any wick in the channels. It was just resting on the deck

I do have a friend who got a "bad deck" with his. It was the clapton though. Could be the case with yours, hope not.

 

[jahines1]

Decks alone are relatively cheap so it wouldn't bother me. But how would I narrow it down to that being the culprit. I typically drip bit I have fallen on love with this tank and am super determined to get it working right without having to spend a shit ton on stock coils

On mine I had to put the cotton in the coil a bit looser than I normally would, almost to the point where I was like "That damn thing is gonna flood" But as long as you make sure that the tails are fluffed out and covering the channel, not dipping in your good to go.

 

[jahines1]

I don't think I've tried it with the cotton being looser in the coil

[Neunerball]

I'm also assuming, too much cotton in the coil, thus preventing good juice flow into the coil.

 

[jahines1]

That could be cuz I think the last time I pulled it out the tails were wet but I was still getting dry hits.

Tried it with the wick a little loose. Hold up better but still getting dry hits. I wonder if it's just not capable of holding up to my vape style.

You need to put the wick in so its has resistance when pulled but doesnt stick or bunch up. It needs to slide in and out easily but not loose....
Then cut the ends to the edge of the tank, fit the cap on the deck and then take it off. Cuts the wick where the indentation is from the cap and then fluff the cotton. Point the wick end up and put the cap over then and screw it down, then guide, DO NOT CRAM OR BUNCH the cotton to the juice holes. You dont want the wicks in the holes but where the deck is above them.
Drop a few drops on the coil and pulse until juice is absorbed, then repeat (with low wattage), this will break in the coil/cotton easier, do this until the wick is SOAKED. Slap the tank on and fill it to the tippy top (I dont even close the airflow) and then try vaping at around 3.85V and go up from there.
I have built crazy builds in all the RBA's, with this method I dont get dry hits or gurgling/flodding and I have vaped up to 120w without dryhits (though I wasnt chain vaping).

 

[jahines1]

I will try that as soon as I get a break from work

I use that wicking method with almost all RTA/RBAs...
These are my builds I have in My TFV4's, if it works for these and for me-then it will work for anything you can make or fit in it.
26g/40g Fused Clapton (TF-R1)

26K/44N60 Fused Clapton (TF-RCA RBA)

2x26K/50N60 (TF-R2 RBA)

 

[jahines1]

Those are clean. And im really hoping it dose work for me. Im really love this tank just cant see paying for the coils.

I suggest getting the TF-R2 RBA, its the one I use most because it holds an extra coil (Easier atleast to do so) and has more Airflow. Try 22g 7 wrap on a 2.5mm bit-You will not be dissapointed for a regular coil in the TF-R1 RBA, the flavor is better then 90% of my RDA's

 

[jahines1]

I only have a couple of guages. I beleave 36 and 38

This is your problem right there...I use wire that thin for Claptoning wires, would not do well as a stand alone or core...
Get you some 22g/24g/26g and then you should have a MUCH BETTER experience....and that will be just a standard to grow from. Then you can clapton/fused clapton the lower gauge wire with your 36g/38g and get as much as you can out of the experience.

 

[jahines1]

I use the 36 and 38 for my drippers. Hadn't tried them in the tfv4 yet

You sure its not 26 and 28? 36 and 38 wouldnt be a good setup for dripper unless its like a pen sized dripper...Like the one below. I think you have 26g and 28g as they are popular wires for new/regular builders.

 

[jahines1]

It might be. I would have to look at then again here in about a half hour when I go on my lunch.

Double checked and your right its 28 and 26

Okay good.
Take the 2 strands of 26, about a foot worth (Hopefully you have a drill available) and twist the wire until there is 5-6 ridges per inch, if it breaks reset it in the drill and keep twisting then try putting it in the holes in the RBA to see if it fits, if not twist it until it does fit.. Then make 5 wraps around a 2.5-3mm bit. It will be sringy and difficult but once you pulse and pnch it it will harden into place and be well worth the effort. If you get it in this will increase the heat and flavor and give you a lower ohm build(.6-.9 Ohms), you should be able to use 40w at the least.
Should be similar to this:
24g Twisted and Helixed with 32g, Spun and Filed

Wouldn't a twisted build on this thing give massive spit back?

All builds give spitback (especially horizontal builds), it will be minimal, if any at all reaches as far as your mouth. If you want to reduce the chance even more then make it a vertical coil (Cotton on the outside) or tilted (45 degrees, cotton through the center)

I'll try it tonight. Just realized that I'm not seeing the bubbles come up inside the tank. Curious if I don't have a vacuum issue

If theres enough juice flow it happens fast enough where the bubbles happen while your drawing from the tank...making it look like its not flowing but it my be happening faster then you think. Try upping the wattage 5-10w and seeing if you can take a 4-5 second pull, if you dont sense any dry hits Id say its working setup.

 

[jahines1]

I'm using a.74 build at forty watts. Slight burnt taste. Upp it to 45 and a decent pull is burnt

I've heard people use max vg on this tank and not have any problems. But it's acting like the juice is to think. My wicks now don't fully go dry but it can't keep up.

I use 82VG/20PG, No dry hits, even with 6 second pulls at 77w...You need to concentrate on the wicking. Its a PITA until you get where it needs to be and after you understand what works then its not a issue any more. You want it dry, fluffy, and just resting lightly on the deck above the juice channels...How is it pulling through the coil when you insert your new cotton It needs to slide in like...well..intercourse after a first session-not tight and not too loose (bad example I know just didnt have anything else to describe it with)

Yes in a heartbeat! I recommend it over the RCA RBA also.

It seem to wick better, more airflow, dual coil and the wire limit is only set y how you install the wires....you can hammer wire flat for the leads and fit BIG wire/coil builds in. I had problems with the Single RBA also and tried to mod it nd then I gave up and bought the other 2 RBA's the dual coil RBA is the one I prefer...

Did you know there is a TF-R3?? A 3 Coil RBA for the TFV4 coming out and a Octuple Clapton Coilhead comes with it...for 11 Bucks..

 

[jahines1]

I saw the octuple Clapton. Had not heard of the triple tho. I think I'm settled.I'm just going to buy the dual coil rba

I've had them get vapor lock if I filled them too full. Both full size and the mini. I use all VG DIY with 10% flavoring and 10% water.

I prefer the RCA with a vertical coil. I also liked the single over the dual, but I've never been a fan of duals and I see no use for them using TC.

Took checking out ten different shops to find a place locally that carried it and it was there last one. Hadn't tried it yet tho because I bought a Clapton coil to ride me over till I could find the rba. We'll update when I try it.

Yeah I'm having the same issue as the OP. Running 24g with a 3/32 ID. I'm wondering if going with a 1/8 would allow for more juice flow to the coil.
When I pull the wick out, it's always juicy and never burnt so I'm really having a hard time figuring this one out. Followed all the tutorials i.e. No wick in the juice channels, just touching the deck, etc.

Still getting dry hits. :/

Have you tried the twisted builds? Sometimes it's not just the wicking but your coil simply getting too hot too fast. Maybe the especially long legs on the single RBA are causing issues? Anyways, as soon as I went to Twisted and Helix builds I never had that dry/burn hit, where I did with strait Kanthal wire and especially strait SS.

I actually had a 32g over 28g Clapton on it before and had the same issue.

Maybe a twisted 28g would work. Not sure how I would get it to fit into those tiny little holes or underneath the screws

I did twisted 26g dual coils on that RBA, it was a bit of a pain but I was able to get them in there. I just had the leads on the opposite sides of the screws so each coil had a small little angle on one of the leads to center themselves.

What ID are your coils? Usually pretty big?

On that it was 2.5mm IIRC, I honestly haven't used the dual coil in a while, since I made my single coil into a vertical behemoth (there's a guide on these forums about it that a few of us have made our own modifications with). But it sits there ready to use if I ever need it, and I liked it better than the quad coil, smaller cloud but more density.

Anyways, I've had a lot of problems with singular wires and heat, twisted seems to have solved that issue for me basically completely. Claptons I haven't really been wow'd by yet. Granted I haven't made that many but I've made 26g w/32g wrap and I liked my strait twisted 26g better, but it's fair to say I may have done something wrong. I do all my stuff by hand (no power drill) so it takes me a while to make a clapton and I haven't perfected it yet (and not much time lately to play with things).

Worth trying twisted at least IMO. Especially if you like to fiddle, I mean it's fun either way.
