Parts of AZ do observe DST, kind of, the Navajo use DST, and a good bit of their reservation is in AZ. ;)

Hmmmm, I'm not doubting you, but strange that the AZ Apache tribes don't. I'm very familiar with both the San Carlos and Whiteriver Apache Nations.

Whats wrong on my RBA setup ? I am using the pre-build spaced RBA 0.5 ohm coil (measured as 0.6 ohm on my mod) with KGD cotton and vaping at 20 watts I can only take around 3 seconds pulls mostly before it starts to be unpleasable and somewhat too hot. Also the vapour isn't good as well. I am vaping with the biggest airflow open .. what actually sucks on it ?
As you can see I am trying to keep the juice channels free and etc. I am not sure what cause that ... I tried multiple times to build it with more or less cotton and etc but its the same ... Any ideas what to change ?

Sounds to me like you're still tring to go MTL. That being the case, it's going to be that hot with limited vapor. The build in the pic looks ok to me but I'm no expert on builds. Turn your airflow wide open, do a deep inhale like you're sucking on a straw, and do it for 3-5 seconds. You shouldn't get a hot vape that way.

I am seriously taking a deep inhale with the airflow wide open and it's not working as it should. At around 4 seconds its getting bad on these 20 watts. Also, I am lung hitting and not MTL for sure. :/
So the coil & wick looks all good ? Is there anything I should improve based on the picture I posted in the previous page on this thread ? here

What's the normal hit in seconds to consider it good as well ? I mean at 3-4 second pulls shouldn't be good and in terms of vapour production as well, isn't the 5-10 seconds pulls with good vapour production a good build actually ?

Cant tell much from the image, but have you tried raising the coil a little higher over the air inlet? Not so high that the chimney hits it, but almost.

Most vapers should easily be able to hit 0.5 Ω at 20W for a while...

You might also try making your own coil to perhaps .7-.8 Ω and see what you think of that vape!

do you take 10 second tokes? maybe my lung capacity is shot but I feel lucky to get 5 seconds into one.. now I can chain those 4-5sec pulls into several successions of 4-5sec pulls but the lungs will never do a 10sec toke wide open.

It's raised almost to the chimney. Anything higher will be too high I believe.

Also, at 20 watts I can handle around 4 seconds but at 22 watts It's already really hot. I mean shouldn't a good build able to stand up to 22-25 watts at around 5-6 seconds pulls without any issues ?

Basically, by looking at the picture, is there anything else I can try to make it a bit better or maybe more cotton?

Yes... definitely yes a GOOD BUILD should be able to withstand a 5-10 second lung hit. I am also assuming that you were taking big lung hits with the OCC heads?

I believe you problem is assuming that the mass produced "spring" Kanger included is a "good build". It is far far from that...
I'd suggest buying some wire and try wrapping your own.

Did you dry pulse the coil before you wicked it? Your photo looks like no oxidation on that coil at all... Always dry fire a coil by gently pulsing it to get it to start glowing, let it cool, pulse again, cool, repeat. The coil should heat evenly from the center outwards, if not you make adjustments. You might have a hot leg or some other issue.

I can take a 3-5 second hit on my STM RBA with a 0.7-0.8Ω coil and get massive dense vapor, so something is wrong with yours!

I understand, however, I dry fire my coil always before I wick it. It's glowing as it should outwards. Also, I don't like the stock OCC heads and I am not taking any big lung hits on them. I went directly with the RBA deck.

May I ask you at what wattage you can take these 3-5 second hits ? Also, 10 seconds pulls sounds really high to me. I am not sure if everyone do that but I believe 5-6 second pulls are somewhat optimal and normal .. is that correct ?

How are you keeping the legs from turning red? Are these NR (non-resistant) wire leads?

30AWG TLP 6/5, 2.5mm i.d., 9mm L/L, t.m.c. = .4345Ω

A straight line length comparison as there's no way to break out a lead twist comp in S-E. Res is closer to .5Ω, a wee bit on the high side.

But this…

Now Captain, didya not believe me post? <In my best Scotty.>

:D

Take a wind off this for a bit higher res. Likewise I'l try an extra wind and higher Ø for the SubT RBA as I have the chance. And yes, your spaced wind should fit with a bit larger loop dia., no cig? I'd try that. Prolly will.

This build's in almost another week in on the first rewick, kickin' some serious.

BTW, all your twisted spacers look tensioned.

:p

Good luck cig. Hope you know we're just funnin' ya.

No NR wire needed T. Thanks for the question. Good one.

The leads are stable on this parallel from the jump because it's just very symmetrical. Starting with the coil itself wound with tension. The purpose of the twisted leads is to protect that symmetry. It is fascinating that it looks like flatwire. That's the effect of uniformity I talk about. Running at about 15-18W it's producing every bit the vapor volume of the OCC @ 30W but with exceptional density. And I'm running the slot full out open to support that vaporization rate. Result, a very luxuriously warm vape with the flavor density normally associated with a much cooler vape (lower watts). However, not any way as airy or hot as the OCC at rated power.

Best part, once you've got a tensioned wind down this one's easy. Thicker wire that's holding it's shape is a lot less challenging to situate, .... with a screwdriver to hold ends in and screw leads down. Why I recommend tension winding to both new vapers and for advanced builds.

Good luck.

:)

Well I just rebuilt(again lol) but this time I did it on a 3/32nd bit(~2.4mm) shooting for .6 ohms, 25 gauge 6 wraps coils touching(MVP reads it at .6 so good enough for me). It's nice and cool at 25 watts. I still can't get those deep inhales I want, but the shorter 3-4 count inhales are much more satisfying than before. It chain vapes better and has better flavor on 2 holes so far versus wide open, which is fine because I care more about the result than how airy it is.


I'm still not thrilled about this RBA deck, but I'm at least making progress.



Nice, and it's handling 30 watts like a boss as long as I don't overdo it.
