I have about 20 coil assembly units, and i can fit a 2mm screwdriver in the slot of three of them. Probably not an original Kanger coil, as i purchased the coils from different sources originally and a few were given to me by a friend who does not re-build. The aerotank coil slots are the perfect size for 2 mm, tight stable fit which doesn't move so you can use both hands for grommet placement and leg termination.

Vap'n on 2mm 2 ohm kgd wicked kmpt2 (no wick tuck) right now. My kmpt2 has two of three airholes enlarged to 1mm. No leaks or gurgles and it's flat out blasting the clouds.

It just keeps getting better as I go up in size. Wondering now if 2.2mm might be even better as it seems the larger the coil diameter the easier it is to achieve the correct cotton density; or at least it's more forgiving.

I also cut my cotton short to keep it from coming in contact with the base. This way the juice can flow unobstructed into the end fibers of the wick.

Increasing the slot size is easy with a pin drill or regular drill. Removing the burrs is easy by scraping the edges with a sharp knife or box cutter.

Thanks for the info Maz...:)

Got a question for those of you with a diversity of contact coil builds under your belt.

Which produces a more dense vape in a kpt; a coil with less winds or more winds (given they have equal resistance and diameter)? Or does it really change with coil length in your experience?

Not so concerned with how fast the coil heats up, how many winds will fit in a kpt or optimal wattage; just interested in vapor density based on the length of the coil.

Curious,
Cig

I have fit 12 wraps of 28 in a kpt, but it was quite a tight fit !

So I'm guessing the 12 wrap 28ga landed somewhere around 2ohms also? That's pretty much where I like to be for my on-the-go ego twists.

Currently I'm at about 2 ohms with 30ga 7/6 2mm. Vape is pretty dense but flavor seems a tiny bit lacking compared to my previous 2 ohm with 30ga 8/7 1.8mm build running at the exact same wattage.

Getting ready to order more wire and thought I might try some 29 gauge and bump up to 10/9 wrap if the vape density/flavor would improve.

What do you think Maz? Have you noticed that the longer coils produce more density/flavor?

Thought I'd weigh in for min cig on the subject of deflection. I agree with f1ve above more wraps whenever it's the option both to increase flavor production and output in general. But let's not lose sight of the fact that higher gauge wire is more efficient (less energy loss through legs as a percentile of wire length). So for you the 9/.07"/30awg (TEMCO) should give you about 2.0Ω which is the holy sweet spot for this tank. Right smack in the middle of the green zone of temperature output. This is an old spec post which I've hit countless times. But these days I'm winding tighter for my own builds as I test new densities of grommets targeting 1.78Ω steam-engine.org along with…

Wire Ø = 29 AWG
Inner Ø = 1.7018 mm
Lead length = 10 mm (16 mm measured median - 2x3mm pin hull length)
Wrap Spacing = 0 (contact coil)

Resulting wire wraps = 10

Nailing it mostly just around 1.8Ω with a low tight wind of 1.76Ω (the approx theoretical) on a good day. It's a great vape on the KPT.

For your ref.

The footnote on deflection is — match the coil to the wick. The total deflection (or real contact area) of a bunch of softballs on your mattress might exceed that of a few bowling balls. It depends on your pillow-top. Firmer surfaces might see more deflection and surface contact from a series of smaller diameters. Line 'em up! Raw feathers don't count.

:D

Good luck.

Cig, I have not used 28 in a kpt for a long time, but most of my builds were on a 1.8mm screwdriver, and if I remember correctly 12 wraps vame in around 1.8 ohms.

As far as vape density, I can't say for sure if I notice a difference, between 12 wraps of 28 and 10 wraps of 29. I wasn't looking out for it I suppose, where I would keep everything else constant and only alter the gauge of kanthal.

I just know I like 29 better in the kpt and 28 better in the kay/tai !

Oh, ..... and, what Mac said :)

Mac, do i remember you saying that the silicone grommets for sale at Lightning Vapes, is less slippery than the kangers ? Just about out of grommets and was wondering if i should order rubber or silicone.

I'm on Sean's website just as I'm reading your post maz. First, looking at the fine selection of raw core assemblies he's got on hand. Since you guys have gotten the jump on me where the dual-coil assemblies are concerned you might wanna take a gander at…

Kanger Protank 3 Dual Coil Head Assembly - Whole Unit or Parts - Lightning Vapes

These appear to be raw un-sleeved assemblies perfect for rebuilding. I've tested out recent whole and component KPT2 as well as M3Ts assemblies and they are of very good quality.

Likewise, the grommets. I use both the silicone and rubber (the latter actually silicone, greater hardness).

I've got a good supply of the silicone which is firmer than the Kanger factory and slightly less slippery. It is a rather flexible silicone nonetheless. For those that prefer it this would be what you want. I use it with their separate pins. You'll have to inquire and persuade Sean to stock 'em. They are of excellent uniformly and slightly off-spec from the Kanger's to the high side dimensionally. These are the pins that will improve termination for the standard Kanger's you may have as well as LV's own grommets. But they are essential to use with silli-caca grommets, you know the silly putty variety. A quick check of pins you may already own should reveal a significant differences. And yes, that does affect your build result…in a bunch of ways.

I've got a few types of higher firmness (rubber) grommets from LV. The material has improved since they were introduced and there's no question the sourcing/material has changed to the better. We are now in the zone of proper termination with a density equal to or superior to most grommet supplies I've encountered. LV's present rubber density is ideal, I repeat ideal. Any firmer and grommet set starts to become a tad too fiddly. However, the off spec pins which I hope he'll continue to stock can help up the termination friction for thicker gauges…!!!

All I can say is Sean's real people and doin' his darn best to up the game for us. He's put us into some serious toys here. So if you're determined to rebuild effectively, LV's lookin' like a necessary pit stop on that electron highway.

No sense having the best in materials if the build cannot be optimized to take advantage of that performance potential. And you guys are demonstrating right here just how effectively that can be done.

So have at it crew and good luck.

Good luck.

:)

Been surfing on lightening vapes and took a look at the PT3 coil assembly design. It incorporates a taller top cap (chimney seal) than the the PT2.
Looks to me like that top cap could be used on PT2s to elliminate the need for flavor wicks or wick tuck when using coils smaller than 2mm.
Might be a great candidate for using nextel slim in 070 (1.8mm) coils without a flavor wick!

Gotta try that for sure.

Currently vaping : Heathers Heavenly Vapes, Shadow (NET ) on a kpt2 with aerotank base 29awg 2.0 mm t.m.c 10/9, KGD cotton at 2.0 ohms, 9.5 watts. Can't say I have had a better vape ever! Happy :)

My kay/tai clones are officially out of commission until I go down to 6 mg nicotine in 2015 !

It'll be faster than you think if you start drippin'.

I started, and stopped dripping in less than a week ! Patriot and Trident clone being exchanged for 50 ml of ok juice !

Not the texture you enjoy, huh? There is something about the density of a consumer tank like the KPT. I keep sayin'.

Thanks for the comeback.
