Protank MicroCoil Discussion!!

[cigatron]

Rewicked one of my MPT2s tonight and got an off flavor right away. Figured it would go away after a while as sometimes they do. Nothing doing. It was as tenacious as I am and even nastier. Pulled the wick and what do know? A cotton seed against the coil. Some days are just like that I guess.

Did that seed have legs?

 

[chet]

Simple way to determine wasup is…pull the wick and take a peek inside the cup with the coil installed. If either lead presents a darkened or charred area at the point of termination with the insulator…you have a short. You may need a magnifier to be sure and/or a penlight or such. I got ya covered on the insulators, if you like; however, replacing the grommet's not going to cure that chet. And we could spend hours here trying to diagnose the body mechanics for sure. Or, you could wind this…

and 90% of those shorts will vamoose.

It's not the grommet that's giving you the foul vape, it's an unstable coil. Sometimes they work, sometimes they don't.

Let us know here and we'll try and help. BTW, wash any lightly cut or scorched insulators well, dry them hot with a hairdryer and you are not likely to smell or taste any residual (unless you shorted really badly and kept vaping). So they're good to reuse. Slight chance of overlapping a cut or scorch but negligible if you're careful at the set.

If you've got the cheap parts we've been discussing here (pin vise, drill blanks or bits) you're minutes away from curing your grommet problems.

In fact, it's hardly even worth discussing what's wrong or right with the coil or set, as I've increasingly been making the argument. It just takes seconds or minutes to make a new one. That's time out of your life. Over and over. Stop tryin' to understand it y'all and just do it. And don't just say that…I hear it over and over…when it's this simple, rewind until your happy with it. That's the part that takes seconds. The fiddling is the maddening part. So if you wasted a couple of pennies of wire no biggie. Time is our most precious commodity.

Be pleased to send you some then if you still think you need 'em.

Good luck.

Thanks so much for the advice and offer Mac. My setup was 28ga microcoil wrapped on 1.5mm rod measured 1.2 ohm. My Panasonic NCR18650PD was fully charged but when under load with this atty the voltage went down to 3.65v, so around 11 watts. I've been always using washed hemp wick so I did expect some unintended taste, but this smelled somewhat like a rubber burn although I'm not 100% positive it is. It wasn't too bad but it's enough to hijack about half of the juice flavor. I'm pretty sure there isn't any short because my ohm meter shows constant 1.2ohm without any fluctuation.

It could also be not enough wick since I used very little of it as hemp tends to swell up alot. I'll take a peak inside to check the wire legs and maybe add a flavor wick and see what happens.

You're welcome. You could have a short with a constant low res. Been there from the get go. What was the number of wraps. Have you checked the theoretical parameters for your build? The premise I espouse is resistance targets. Easy to do on an external build such as a dripper as the consequences (typically) are visible. Harder in a tank. I've gained some respect for Coil wrapping | Steam Engine | free vaping calculators in helping me determine whether the resistance I've reached is friend or foe.

A check of the grommet termination and res spec should help isolate the problem. I mean certainly wicking material can be a contributor but at the heart of the issue regardless is heat generated. Where's the source? A loose turn? Technically a short (wire heating air not work, higher than req res). I think the opposite of your situation but maybe not. Perhaps you should be lower as we see your turn count.

Good luck chet and I'd love to know the outcome.

Thanks.



p.s. My read on steam-engine...28AWG, 8/7, 1.5 i.d. 2.0 mm i.d., m.c.= 1.173Ω, fyi.

p.s.s. BTW, great choice of batt for a PT variable. I've been workin' my original collection hard for well over a year now without a single failure. Still running strong, recharge consistently to full voltage (XTAR VP1). Got bunches but can't imagine I haven't exceeded the rated life cycles on these beauties. Obviously keeping short stress down pays dividends.

I love to wake up to fresh cotton in the morning!

In my favorite dripper. Yummm...

You're very funny. Great tag line.



Good luck.

Me too. Or, better yet, about 5 setups....ready to go.

So ib have officially converted another family member from smoking. Another pt2 user built up his coils to 1.5 hes good to go. Few more friends to go and ill have converted them all

So My Friends,

It would seem that most of us that have been here for a while are capable of a proper coil build or soon will be. Which brings me to this post.

I have been doing my coils for a while now although not properly in the beginning. I have used silica, then organic cotton, then rayon. I'm still not 100% sold on rayon though.

Another thing that can effect flavor is the PG/VG ratio that we use. There are vendors that seem to use a proprietary blend where you have no choice, places like Halo, Bionic Vapor and Nicoticket are a few.

So what are your choices and why? Just curiosity getting the best of me I guess. It's always good to hear what people prefer.

I personally was using Halo e-juice exclusively and was really getting bored, my guess is maybe an 80/20 pg/vg. I decided to make a drastic change and ordered some juice from 3 or 4 different place and went to a 50/50 mix or whatever the proprietary blend was. I'm still working on opinions of that move. The vape density is definitely much more dense and that's all I can attest to so far.

As many here I'm still learning as many here are. Opinions are a great start, so what are yours?

 

[clnire]

Some juice I do 50/50, but most of the time 30/70pg/vg. Higher pg seems to suck the moisture from my mouth and throat, and can give me a sore throat.

I make a lot of juice, all at 70/30 VG/PG. I flavor heavily, and get both great flavor and vapor from this mix. This is also very popular in the marketplace, particularly with the lastest, greatest drip craze, and way more 3mg/ml nicotine mixes than I've seen previously. Drippers.......gotta love 'em! They fly through the stuff!

 

[PaulBHC]

Started out with 50/50. Bought some that were 70pg/30vg and some others that are 30pg/70vg. Started DIY with 50/50 and now 25-30pg 75-70vg. Bought some Open Source Vapor that is 100% vg just to try it.

I'm past the point of needing a harsh throat/lung burn and like the smokey cloud that a higher vg gives.

I'm with ya Paul. PG gives me heartburn. LOL

Vapor production declines dramatically with PG. And so does flavor as far as I'm concerned. Now taste, that's a horse of a different color. And texture is most definitely part of taste. But I don't need throat hit or dryness to define my flavors.

So sombadi pleez to 'splain gwy we juz pee-jee?

SOTB

 

[crg31953]

So if pg is the flavor carrier and vg is vapor why does everyone seem to prefer higher vg? Is this a vendor issue?

I agree Mac, throat hit has become a far less priority to me over time! As I said it could be vendor issues that cloud the flavor. I have found that some vendors at least with me, the longer you steep the less flavor you have.

Forgive the ignorance here, but if pg is flavor, how can a 70vg/30pg carry the same flavor as 30vg/70pg?

Actually it's quite perplexing to me. I have it on good authority from juice producers I know that PG is more expensive. And I keep asking them, why do they use it? I've yet to hear a plausibly justifying answer. Like so many other things we do in this phenomenon we call vaping — why do we do it? Just askin'.

 

[chanelvaps]

I have almost always been 50/50. Deviated a few times, when I heard PG gave more flavor to 70pg. Got heartburn and acne. Deviated the other way on occasion because some fo the things I like are a higher VG (Omega and Cyclops) but too much of that gives me phlegm so I only do it in small doses.
preference is 50/50

 

[chanelvaps]

It does seem like there are a lot more 100% VG (or high VG) juices moving in. The Vape Kitchen and I think Coval, Good Lifes Nebbia line and Velvet Cloud. There are quite a few out there that are promoting 'mostly Vg" juice

 

[crg31953]

So are the cloud chasers taking over?? I surely hope not, because a lot of us are here for flavor and have figured out how to do this at a reasonable price!

So now Kanger has got into the dual coil/sub ohm category and why?

I presented the post for all of us, and hopefully Mac don't mind, was to help show that the quality is not expensive.

Most of us are not cloud chasers, yet some of you may take that rout. You will leave here with a basic knowledge of proper coil builds and air flow issues or the lack there of and I don't condone or condemn personal choices. We all have them.

I do believe that if we occasionally get a little OT and discuss ratio's and wicking that this thread will be a start for any noob or experienced vapor to latch on to for the basic knowledge that Mac or anyone else can provide.

Sorry for venting here, but I believe in the efforts made here in this thread!

Vape On and Enjoy!
