You can use this method with silica but, I use this with natural 1mm hemp twine. It allows for swapping of the wick without replacing the coil should you need to. The original post is here and contains good info from pg. 8 on with the tutorial beginning on pg. 9

It was suggested I start a thread or blog it
Quick artistic rendering I did in s memo for another user in another thread. Save the accolades. Lol it serves it's purpose

Explanation FOLLOWS after the photos

That first image is a hook I made with the excess 32g Kanthal a-1 I trimmed from the legs to feed the wick. You'll want like a 4" length of 32g Kanthal a-1. Heat prior to using to remove impurities and makes it more malleable..
Disassemble pulling the top post gently but, firmly while wiggling slightly. It's a friction fit. Use the needle nose pliers . Then remove positive pin. Should come out easy.

Un hook positive wire from insulator gasket/grommet and pull out with your fingers.

Remove old coil and wick.

6 wraps 32g Kanthal a-1

Remove and place on paperclip. Paperclip is thin enough to reach the bottom of the v-groove in the wick opening

Grip like so to keep coil in place. Thumb on atomizer body. Fingers on the paperclip

Be sure the wires correlate with the side of the coil they are on. Slide the longer wire through the center of insulator gasket. INSIDE. This is your positive. Flex the other wire to a 90°. Insert gasket pinching it slightly keeping the flexed wire on the OUTSIDE of the gasket. This is your negative.

Flex the positive straight wire to a90° opposite the other negative wire and insert your positive pin.

You should have one wire through and under the gasket and one outside and above the gasket.

Make sure your coil is aligned. Feel free to use the toothpick to adjust and center. Then trim the excess wire as close as possible at the base.

Coil is aligned with base of wick opening. Cut piece of wick. Wind it tight and slide through coil. May have to use that hook you made with excess 32g Kanthal a-1 to feed the far side of wick up and over the base of the wick opening.

Place additional flavor wick on top of coil. Align. Replace top post keeping flavor wick aligned and press into place against a hard surface. I suggest using some kind of buffer between your thumb and atomizer. It could dent a wood table so use some kind of buffer there too.

A cloth or paper towel work just fine as a buffer.

Replace the gasket that seals the atomizer and body tubes together and whhaaa laaa. You've just rebuilt your first EVOD or ProTank head.

Just did that real quick.. hope it helps..
I used the extra 32g Kanthal a-1 I trimmed from the legs to make a hook to help feed the coil wick through the wick opening on the far side. That is the 1mm hemp twine. Natural wick expands so 2 pieces is plenty...

Also this setup allows you to replace the natural wick without having to replace the still good coil should the wick go before the coil. Remove old wick. Quick dry burn off the coil only. Replace new wick..

Gorilla Juice after 4 puffs. No gurgling, leaking.. anything
It's not the head in the images. I might trim those closer for the ProTank but, you get the idea..

Thanks Boiler. I've found better performance from the natural wick. Holds more liquid but, doesn't wick as fast. Just needs longer at first to absorb and a few primer puffs before firing at low voltage then slowly turning up once you know it's good. Once it's going it more than keeps up.

No second chances with natural. If you do burn it just takes minutes to replace with this setup.

The stock ProTank heads don't do 100%vg well.

I'm using 1mm hemp twine natural from love pedal on eBay. Boiled thrice,20 minutes each, new water each time. Then immediately oven drying on WARM setting 150-170° overnight...

I have some cotton yarn (Peaches and Cream I've seen recommended) but it wasn't ready yet so I cannibalized some silica from a spare Nova head. It was difficult to make a decent coil wrapping around a limp piece of silica.

I'm also using 100% Vg and my cotton is boiled out now and ready to go when this coil goes.

I sent you the outline PM so you can post this as a blog. By tomorrow Unforeseen will probably have moved this thread to the "tutorials" sub-forum and it might get buried.
I got it. It's perfect and awesome. I will take care of that once I'm on my comp. Thanks very much

I know. This place buries things. The search engine isn't good either. Better off using Google..

I think you'll love it. The cotton I used worked just as well I thought. Just give it more time initially like I said. Primer puffs and low voltage initially.

I should of mentioned that silica will work with this setup. Just may need more pieces depending on size. If the silica was 1mm I would do 2 through and 2 over. Doesn't expand like the natural.

Looks like you wrapped it 6 times. What ohm does that come out to. And is it less for less ohms etc...

Should give you 2.3-2.5ohms. Yes less wraps for less ohms.

4 wraps would give you around 1.8-1-9 which is what you want when you don't have a Variable Voltage device. With VV you definitely want higher ohms.

Resistance(ohms) is also relative to wire thickness Crock. A thicker gauge like 28 would probably read at 1.1 ohms with 6 wraps around the same toothpick.

It's weird, the search engine used to be pretty good, but it changed.

And Google indexes in almost real time. Eddie's rebuild from the prior thread already shows up in a Google search.

I learned that my first week. I couldn't find anything I had been looking at but, hadn't posted in. New window, Google. There it is...

You do a search here and the return literally has nothing to do with your search...I don't know.. it's free right?
