Suggestion for New Protank Re-buliders...TWIST YOUR KANTHAL

[pauly walnuts]

I realize there are other Protank Coil threads which are very informative and extensive. I didnt want this getting lost in the vastness of some 300page thread, as it has completely changed the way I think about rebuilding my coils. So, here ya go.

So ive seen others use twisted kanthal on other builds and have heard of it used with the protank coils. I was hitting a wall, getting really good performance with boring consistancy from 30ga kanthal and 1\16" coils, but im always looking for something better. Well, I found it and it rocks.

First off, your gonna need some kind of locking pliers or hemostats.
I used 32ga kanthal, doubled it up, locked the open end in the pliers and stuck a toothpick through the looped top.
twist, twist, twist Once it looks like rope, maybe 30twists per 4inch section (8inches before its folded over), your good.
Torch
I used a 1\16" drill bit to wrap, 8wraps(1.4ohm)-11wraps(1.8ohm)
compress coil and torch
Install in coil head

I used cotton yarn, a full piece works best (end pinched and twisted to thread through) , but you can use what ever suits you.

I found, that the 8wrap coils almost produce too much vapor (which may be perfect for 3.7v batteries), but the 11wrap coils are quite a bit smoother on my vamo.

The good news is, these work fabulously on ego batteries and dont seem to require a VW to perform decently.

Hope this helps someone get a better vape from their protank.

Nice idea for twisted in a pt rebuild, I like 30 guage micro coils and use them in everything. I have some spare 32 and will try that next. Thanks for the ideas.

Not much room in the protank heads, I would have thought twisted 32g wouldn't fit in there. Got some wire on order should be here by Monday, will be trying this. Thanks for the tip.

I found that 11 wraps will just fit inside the protank head, and using the 1/16 drill bit to 'seat' the coil gets it low enough that it doesnt hit the 'stove pipe', and high enough doesnt burn the grommet (mine are the translucent silicon grommets, not the white rubber).

The key is squeezing the coil together then torching it. If it was a loose wrap it would never work.

What impedance did you get from that set up?

Ive been rebuilding for a little while but I have yet to mess around with twisted coils nor have I ever bothered trying to rebuild one of my PTs.

1.4ohms with 8wraps to 1.8ohms with 11wraps. This is the farthest ive gotten and i havnt tried 9 or 10 wraps, but I can surely say theyre somewhere in the middle.

The protank coils lend themselves to being rebuilt. The difference is unbelievable from factory coils, my rebuilds blow them away. The best part, its soooo easy once youve done it a couple times.

Let us know what you think, id love to get some feedback.

Been using the EXACT same build on my pt coils for a bit now as well. Usually round 9 wraps though.

Have to agree that the build is leaps and bounds above a single wrap and the factory coils. Least for my taste.

7 wraps of 30 K1 give 1.7 ohms. Have some 32 here and may give twisting a try. Love my protanks because they are rebuildable.

Just rebuilt my GFs protank.
Guess I am spoiled by Kayfuns and RDAs cuz that was a bit of PITA!

Did a contact 30g coil with cotton.
Def much better than a factory head but not sure if it was enough for me to pull my protanks out of emergency reserve status.

Never did it in a ProTank, but I might try. I have quite a bit of 32ga on hand. I did do a 3 strand twisted coil for my KFL, 10 wraps on a 16ga needle, 1ohm. Wicked it with cotton and it performs very nicely, but not over-the-moon substantially better than a regular 30 or 28ga micro coil.

With my PT's I have been very happy with 30ga micro coils at 1.8ohm wicked with cotton. I believe the substantial gains can be made by perfecting the wicking and coil build techniques within the limitations inherent with the PT2 design. I agree that a twisted wire coil presents more surface area to the wick and thus, results in more flavor. There is however, a limit to how much a PT can actually effectively wick. I believe if you stay above the 1.5 ohm range, all should be good.

I will try this coil. It sounds like it probably pushes the performance limit of the PT right to the edge. Thanks!
