My path to the best mini pro tank 2 performance

[jiminsandiego]

Total newbie here. Got a mini PT2. shop said drill out the holes OK. Internet says flip the grommet around OK. You tube says take the silicon wicks out and use cotton OK. You tube shows how to rebuild coil (32 ga.) and use yarn OK. (By the way, this thing seems to be working very well and getting better and better.) I also replaced the metal tip with a plastic one, and got a full set of o-rings. Vey happily using an ego twist at 3.5v and 1.8 ohms with cotton yarn. So….how else does one improve on a mini PT2? Perhaps thicker wire/micro coils? Mesh wicks? Flat wire? Something I've overlooked? Any input is much appreciated,
Jim

Sterile cotton balls for the wick... ;-)

Microcoils with 30g wire on your vv battery.

I had the flooding problem with my Hypertank. The solution for me was leaving the gasket the way it is supposed to be. I then cleaned the coil threads on the tank and changed to a 2.2 OHM coil. It stopped the flooding.

Consider the vertical coil with cotton stuffed around it, and leave center clear for airflow.

Not something I can do myself, but others have done it.

Throw a micro coil in there and you'll never look back.

I have my Kanthal on order. Going to do a 28g Microcoil. Can't wait for my first coil to fail miserably

 

[Rossum]

28 gauge strikes me as rather aggressive for a Protank coil.

 

[jiminsandiego]

Thanks for the input folks. I tried 28 ga with 12 wraps (youtube). However… it seems like a rather tight fit. So I think I'll try 30 ga next. How many wraps for 1.8 ohms? Vertical coil sounds cool. Any you tubes or thread links? Any one try mesh wicks?
Thanks again folks,
Jim

Quickest easiest method:
All of the protank/EVOD coils can use a very simple "tuneup" it's not rebuilding em (it's like putting better sparkplugs, wires and a new air filter in your car)

The silica wick over the coil wick sometimes gets loose or is too tight and either results in dry hits or gurgling

A very easy process to fix it is available
You need some organic cotton and a pair of nail clippers

1. Remove the chimney and rubber cap
2. Remove the silica wick over the coil (leave the wick inside the coil)
3. Take a tiny strip of cotton roll it into a string the same width as the coil
4. Lay across the coil
5. Replace the chimney and cap catching the cotton under it
6. Snip the extra off with nail clippers
7. Reassemble, let it sit for a few seconds to wick the juice into the cotton
8. Vape Yo Face Off!!!

Tuneup, not a rebuild

Best method but has a rather large learning curve is to "rebuild" with a micro coil, I wrap 10-12 wraps around a metal dripper bottle top , squish wires together, put in tweezers hold in fire, build the coil, pull some cotton thru the coil, put a cotton flavor wick...whammo! I am throwing an AWESOME vape with 1.8Ω-2.0Ω at 6.5watts...it's actually amazing how well it performs

 

[jiminsandiego]

I did the "take the silica wick out, dry burn the coil and replace with cotton" thing but after awhile the "stock' coils got dirty and the cotton was impossible to remove. Youtube makes it pretty darn easy to learn to make coils and I'm finding that a fresh coil and cotton wick is a good thing. 32 ga with 4 wraps is a breeze but 12 wraps with 28 ga not so easy. I'll try 30 ga next. I bit the bullet on a $20 ohm meter made for vapors and am glad I did.

Doesnt matter the wraps; its the length that matters; get an ohm meter.

use the ohm meter to measure out a 1.8 ohm LENGTH of wire; THEN start wrapping your coil.

It's funny, i don't mod my pt's at all. Reading the op made me think about how weird it would be to rip apart a tailor made and make a rollie out of it because it would work better.

Geez, I remember a thread just like this one titled My path to the best CE2 performance

edyle,

Does the shape of the wire do anything to its resistance? Or does that whole electromagnetic-field/coil thing only apply to something like transformers, as in induction? Just wondering if a set length of straight wire is the same number of ohms as one that is twisted into a coil. Wouldn't tight-touching coils have less resistance than one that is spaced? My old meter isn't the best for low ohms and my new iTaste V3 isn't something I really want to experiment on, even though the built-in meter seems to work very well for my 2-ohm-average Kanger rebuilds, better than my old meter that I always had to be conservative with.

Just wondering, thanks.

I have my Kanthal on order. Going to do a 28g Microcoil. Can't wait for my first coil to fail miserably

Do set yourself up to fail, have confidence going in! I just built my first coil about a week ago and was successful my first try. Infact, I have not built one yet out of 10 that didn't work. You will be good to go!




As many have already mentioned, I rebuilt my coils and use cotton for the wick and I have not had a problem since. Like the OP, I tried many other methods as well which failed and was about to give up on my MPT until I learned to rebuild. I use 32GA Kanthal with 5 wraps around a 1/16th drill bit and I am consistently getting 2.0 ohms. Problems solved!

 

[tj99959]

Wouldn't tight-touching coils have less resistance than one that is spaced?

The irony of it all
As a general rule I expect the resistance of my coils to go UP by about 0.1 ohms when I squeeze the coils together into a micro coil. The coils insulate themselves when you build a micro coil (just like oxidizing a SS wick insulates it from the coils) It's the thermodynamics that changes with a micro ... not the resistance.

I just built my first coil about a week ago and was successful my first try. Infact, I have not built one yet out of 10 that didn't work.

You have needed to build 10 coils in a week?!? Must be just having fun building coils instead of using them. I've been using the same coil for over a month.

 

[STiZzle2010]

Lol I had quite a bit of coils that were no longer working. Some were duds and others were for a friend but yes, I did enjoy building them!

So "Infact, I have not built one yet out of 10 that didn't work." isn't exactly true.

Don't feel bad, you don't even wanna know about my first attempt at building coils.

In terms of wire shape, it is the cross sectional area that matter; like a pipe; a fatter pipe passes more water; by shape of wire here, I mean as in flat wire versus round wire, but I'm now thinking you meant something else.


By shape of the wire, I think you mean as the a coil shape:
electromagnetic field thing applies for alternating current; not for direct current; which does mean in practice if you are using a 'mod' with voltage regulation that actually puts a rippling voltage component, then your 'impedence' will be affected by the coil shape because of fluctuating magnetic field producing back emf.

but in theory, if you have just plain direct current from a battery, the impedence is purely resistive, whether the wire is straight or coiled.


touching coils ought to end up having less resistance because they supposedly would be shorting out; but according to what people report here, the condition of coils can be made so that they don't seem to short; presumably they develop a surface insulation of oxide preventing shorting out of coils in 'microcoils' just as oxidizing steel mesh helps prevent shorting out the coil.



Getting back to the coil shape, its unnecessary for dc battery current; you could just make it zigzag, or spiral; on the other hand the concentration of metal to a small space is relevant to our application, and that it what 'microcoil' is about- alot of hot metal within a small space.

If you could heat up a thin flat horizontal steel mesh and drip on it, I bet the vape would be great.
