Picked up post from Re: Subbies CAN go deep and rich! on the Protank MicroCoil Discussion!!
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
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
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.
