What %vg too!

Running 85% VG this initial test. An avg as I've only evaluated down to 70% this past year and I'm not going to get into that discussion. I can't do all the pictures tonight either. Took a record I'm sure as mostly auto fire. And I've already found a few anomalies I'm not pleased with. But I didn't expect this first one to be ideal. However amazingly it's just coherent enough to be vaping cooler than I hoped at the vapor volume I had as I wrap up this first fill. At least meantime I can give you an advance shot and conjecture on what this might be…

Campers, it'll fit in the post spread fairly close. Little risk of end-turn leg skew with this wind. So if you whip out your coiltoy you'll find what fits. It also took two tries to wick it. I ended up doubling the wick density as running dry almost immediately at 10W. It was of course breaking in but I made a good guesstimate which so far has been holding up…the 2/3's part of a 3/8" width of KGD. Yes that's a wad of cotton. The tails are a tad, mm or 2 longer than what might seem intuitive and slightly propped up to help avert gravity sag. In the pic they're tucked in between the posts to allow installation of the rba sleeve.

Be back as I have a chance to look through all this stuff and see where I'd best put pics as I'd like to do a few this time. And take follow ups of this build which I've not done before.

Be a little patient, I've got a number of things cookin'

In the lower right background is the fuzzy distortion of a coiler wind, best I could get today, which I intended to run in tandem. However it pancaked real bad like so many I do on those darn things. All these hotplate vapers can play with 'em and make earrings as far as I can see.

But here's the glad news for me, the flavor potential is there. It begins to approximate what I'm getting with the two testers I've been using all along, my Raiju's and Immortalizers. Given the inconsistencies I noted in this build including a significant wire bend which I almost missed ending up on the coil bottom and a factory wire defect which is seen in this pic, performance did not peak. That is, I know this coil can build cooler. And by that I mean chuck more density. Vapor is all there is even on one hole. So the flavor potential <shrug> anybody's guess at this point but certainly better than a Mega. Which incidentally is vaping very close at this point for me* to my two reference standard devices.

Hope this optimistic news is encouraging. Be back at ya.

Good luck meantime all and enjoy the vape.

:)

* With the v3 slit multi-hole base!@ A footnote that the Mega really needs airflow to wring what little vapor volume the 510 allows and so its flavor potential.

Friend brought her son over tonight to build a coil. He is a cloud chaser. He has never built a coil and is at the mercy of paying the guys at the vapor bar to do it for him. Set him down at my coil station with magnifying light and some 26 gauge and let him play. 2 hours later he had it down pat. Loved the Cigamijig more than any thing else. He was pretty happy with the build he left with. Because he was so enthusiastic I ended up giving him my cigamajig #1. He was pretty happy to get it. I will be moving on to my more advanced Cigamajig

Oh, the suspense is just kill'n me!

Sent my brother a pic of a dripper cloud @50w claiming it was my Egrip @15.5w. Good times.:evil:

Oh, you're a bad puppy cig. Yep, caught me.

I bought a G-mod on the cheap from vapordrek and runnin' dual 16's [snappin' fingers].

:D

G'luck.


p.s. Frame one is the back end of chain 1 being followed by the rising remains of 2 and chain 3 in the remainder. Point being cig, the little twist is putting out some density in 5-6 secs along with the great vapor volume the subbies seem most suited for.

Kinda got caught up in a little concern that almost stopped me in my tracks with the Mini release and the darned insulators. I thought Busardo was talking about the 510 end as so many peeps call 'em that. But it's proven to be perhaps a more serious problem. Took the time to ack jc87 whose been ringin' the bell on this here and on other forums as it's entirely credible given Kanger's apparent ack and response. IOW, possibly not just isolated incidents. But it did stop my research. MOF, just got an answer from him.

Anyway I've got an hour here and I'll do my best.

My approach as I've recommended on this thread and I'm sure cig, brook that you and others do is…to build for the device. Find out what the tank needs. Goodness we have so many tools around now and particularly so with steam-engine.com and the mod specs integrated right into the online app. I did that of course and decided to go in to opposite direction to the above. Yes build geometrically for the optimum space screw channel-to-screw channel, minimal tight leads but at the optimum efficiency I could muster to find in such a wind. It's not a beginners build but hey. I had a chance to thoroughly check this PEEK insulator question as I've got one. And tensioned parallels are easier to build and rock solid steady when the leads are twained. The method's pretty straightforward and I'll be taking it up on this thread.

Had the overall post width (over the screws) at ~3.2mm, the span between posts @ ~2.2 and the cross-post coil bed span at 7mm for the RBA accessory. My inclination, as was brook's, to go for the juggler and a workable straight-wire reproducible single. A wind that favors the common sweet spot for many APV's lately at around .8Ω. I think brook came close with his t.m.c. and glad it's workin for ya bro. Here's what I threw at it to meet the most congruent minimalist geometry...

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



attachment.php



As I mentioned yesterday, I had to double the wicking density as it was clearly insufficient at 15W. What does this mean? Well cig for one, we may have to build more wire into these guys and chunky wicks. Or, alternatively high-flow synthetics if feasible. That may mean hybrid wicking to avoid the hula-hoop. Mind you I have been testing twisted leads for a while down to and under my personal sanity limit of .3Ω experiencing nothing but explosive performance and very cool results. But I was very skeptical about including such a wind in a small high-pressure environment that the transition benefits wouldn't be overcome by heat concentration from the likes of this…


attachment.php



Not going to show you some full temperature yields, that would be obscene. Write me. This was not a tight wind. Even at full 10-sec full temp burst, leads stayed cool. However, this was not a perfect build. One small wire imperfection may have sent the whole wind hot. And it proved so during oxidation as I had to prematurely cut it short departing from my technique. So I was expecting a rather hot build on several counts.

The wind definitely shows promise. And I must find a place to anchor wire for parallels as I'm going to be building a lot more of them than I have. Certainly for each and every block post device in my collection where they are ideally suited. They fire fast like a light single wire coil and deliver power like the high-mass wind it is. And the narrower turn width and coil thickness puts a maximum of surface area for coil length of anything you can wind. The problem with parallels as that they typically result in a slight to much drier, hotter vape. Not so in this instance or for tensioned twisted leads. That's the point.

Check in anyone needing info on producing these uniquely satisfying artifacts. And I'll be back with a follow up.

Good luck all.

:)

Congrats Mac, glad things worked out there. The insulator is deff a concern. I have the clearish one. Don't know how that's gonna turn out.

I have done several iterations of twisted lead parallels on my dripper. Using thicker gauges for single coil .25 ohm builds the heatup/cooldown times were longer than I liked. Did one dual 30awg build identical yours hoping for magic at .25ohms. It vaped really good. Have since moved back to single strand duals at .37ohm for easey peasy and batt life reasons.

Way to go....awful pretty!

Ps. I figured out the wicking has to be heavier in the minisub than what I'm used to for sure. Vaping it now at 25w with a tightly twisted 30awg tmc.. Up 5w from my previous experiences.

I've set up a lot of Kay's, Aqua's and others for bunch of peeps but this is the first "rna" I've run (exc. genny's). I am having occasional dry feed on this when I tilt it and disrupt the air column below half fill. That'll take some getting used to. And this build is very much tied into a very narrow zone. Lot's of power, low end, lots of density, good vapor. The opposite of beaucoup power and heat. So yes on the thicker builds but you need that to build up the production…more power, more vapor, more flavor. Like I said, chunky wicks, lol. But with this build I could use more juice flow to really open it up. The opposite of what I see on the Mega. Don't think I'd like the res any lower than this for that reason. More than enough power with this wind.

Looks like there's more build potential here than I expected. I'll try and head higher to >.8Ω for some more balanced results. Gotta def try to break the habit of tilting this. The old Protank tilt to induce air when saturated. Bad habit.

This one'll swap to the sub tank for continued testing.

Thanks for the nod cig.

:D

Good luck.

Maybe more like 1.3-1.6ohm. Less wire to heat/cool and more controllable temp by varying draw effort. Don't see a subohm build being needed or even desirable for power levels under 25w especially when limited/irregular juice flow from the tank is the culprit. These are just my thoughts based on my limited tests with the SM.

Gotcha, that ideal would be right in the .8Ω mark for most of my APV's. I was actually kind of acceding to you that the power build is rather thwarted by the fluid flow; my take, unless you go really airy and light (the design) to the middle of it's design range, or 15-20W. I'd say because the juice channels are designed for that, i.e. optimized for the center. Above that and you're not going to see the vapor unless you produce it through diffusion of that limited flow. Pouffy bear wicks and hula-hoops.

So a preliminary conclusion here that if you're looking for high wattage density, this would not be the outlet for you. However, with this wind I got a fairly respectable showing as good as some RDA's I build at .5Ω or lower. That's saying something for any consumer tank, that's it's capable of that.

My wind selection as intended to max a balance of output in the rough center of Kanger's recommended range. I think most will be happy there at 15-20W. Although quite a few who've participated on this thread over time have been quite comfortable well under that. Insofar as the build and power, doesn't it depend more on the chip? What the designer targeted as a priority in the power curve. Have you seen steam-engine's power presets in their mod eval section? Anyway, we're talkin' tanks here. I've had an assortment of devices I've run out to max power on all the boxes. And I had a ZNA long before the current variable craze. So I know how to build for flavor at those levels. But it's going to always be somewhat elusive in an RBA without adjustable juice flow. The way I've always seen it is you've got to have a wick capable of it and that's where synthetics may lend a hand, the ones we have now and perhaps alternatives if the makers get their stuff together. I'm a fan, as you know.


IMG_1414a.jpg IMG_1415a.jpg IMG_1416a.jpg


It is chaining comfortably at 15-17.5W but I had hoped for the full range to 20W. given flow. To put it in context the max vapor shots were taken at 15 W. The fire test stream, 10 secs long, was done at 12W. It's a really fast quarter mile to that bright red bar (pictured), <1sec. Can I tell ya? I'll be workin' on this wind and some possible variants in this range to try to cool it down some. Eke some more watts out of it with the given flow. That would make me a happy camper. Then it finally becomes a candidate for the wind/tank combo I've been seeking for Tribeca which is favored by a cool side for the very kind of fast chaining you enjoy but which I also favor at higher wattage at times. This may finally be the answer I've not had the time for this whole past year.

I gotta stop puttin these on their sides and tilting 'em tho. Yikes. Hadn't crossed my mind just how pernicious that habit could be to flow.

Good luck all.

This build is working ok in the mini. Plenty of warning when going dry on juice, which my mini will do at power levels exceeding 25w. This build and rtas in general need much heavier wicking than protanks. The wicking needs to just touch the deck and be kept away from the juice channels. I cut my wicking, juice it up and put it in position before screwing on the chimney. I cut the wick at a 45° angle while horizontal so when it gets bent down to touch the deck it's square; all wick tails touching the deck.

Build is 30awg twisted(27 twists per inch), 7wrap, 7/64(2.77mm) ID, 1.1 ohms, tmc, KGD wicked very heavy.

Folks, admittedly there are some things I just can't explain. Like why wicking heavier in any rta encourages the larger size and quicker transition of air bubbles into the tank. This allows for much speedier juice flow and allows for higher power levels before dry hits. I just don't understand it; seems counter intuitive but it works. Just so happens that twisted winds need more wick too so....win win. I also can't get a handle on why the lemo with a similar build and airflow setting can bang away at 45w all day but work perfect at 25w as well. Also don't understand why my Egrip with 1.1 ohm twisted and an itty bitty chamber can chain at 20w and stay so cool compared to the sub mini. Bugs the ....outta me......whatever!!!!!!

Chaining this build at 23.5w with slightly elevated heat at the drip tip; more than I like. Cloud production is slightly diffused but ample. Flavor is really good now with only a slight metallic taste(kanger); very close to the Lemo and only slightly sub par to the Egrip.

Thinking of spreading the turns apart a tiny bit to cool things down and add a little more temp predictability to this wind. Effeciency will suffer for sure, albeit minimally imo.
