open them all to 1mm, but the main feed to the coil still stays the same.
Altyd 'n plesier Johan!
Awesome post @free3dom ! Thanks for all the pics and steps. Someone will find this very helpful for sure!So I had to rebuild the coil for my MPT3 (using a old style dual coil, the one that came installed in the MPT3) - decided to share the experience
Coil specs:
Single coild, 30G Kanthal, 5 wraps, 2.5mm ID - came out to 1.7 Ohm (a bit higher than I expected, but works quite nice actually).
Here goes...
The prep - the removed coil from previous build was 2.2 Ohm (cotton wick)

I noticed that the gromet had a bit of scarring, but it was still good to go
View attachment 13910
The coil - initial wrap and after some heating and squeezing to get it nice and tight (I could have done better though, but I got impatient)
View attachment 13911 View attachment 13912
Wicking it with organic cotton, and placing it in the cup (I find this the easiest way to keep everything in place)
View attachment 13913 View attachment 13914
Making sure everything is aligned while bending the legs and inserting the gromet + pin
View attachment 13915 View attachment 13916
Tweaked the position a bit with a needle and then testing the resistance
View attachment 13917 View attachment 13918
Now just priming the wick with some juice, then re-assembling it
View attachment 13919 View attachment 13920
And finally screwing it back into the MPT3 base (tucking the wicks inside so it doesn't interfere with the threading), filling the tank and she's ready to vape - watching the bubbles as the cotton drinks up the juice (the level dips quite a bit since I did not prime the wick as much as I could have).

Gives a really nice vape, decent flavour and good vapour production.
Final thoughts:
Not as much fun as building for an RDB/RBA but really not bad if you have some of these old style dual coils (the new ones are a pain to build with, IMHO). If you have some of those lying around keep them safe, soon I expect they will be very hard (impossible?) to find. Clearly the new style coils were an attempt by the manufacturers to prevent what I just did here because (at least to me) the new style coils don't vape at all better than these ones - and they give more problems too.
Bonus features:
So i've built up a small "coil graveyard" and thought I'd share that too

Nice tutorial, thank you.
I just made one with 30g and 6 wraps and it came to 2.0 ohms.
I wanted to get to around 1,6, so this helps
Seems we both overshot a bit...I was actually aiming for around 1.4 - seems we both need to lose a wrap
"Does this wrap make my coil look fat?"
if you doing 4 wraps around a 2mm drill bit, you will get it to around 1ohm if im not mistaken
You are right (according to my calculator). Thanks a lot
awesome!!You are right (according to my calculator). Thanks a lot
I've been using 2.5mm ID, and it seems that 5 wraps around 2mm would be perfect for me @ 1.3 ohms
Will give it a go Chop! Thanks bro!So a guy, or girl, walks into a vape store, or goes online to find their very first vaping device. They are told the coil in this device is supposed to last 2-3 weeks, when in actual fact the bugger usually doesn't make it past the first week. If it does, you are lucky, if not, it is put down to 'user error'.
Now this is all very well for making large amounts of cash off those poor schmucks by selling pre-made coils from Mr lee Wong Dong in China, week after week, but lets suppose that poor guy or girl works as a waiter or is a student and has saved up money for 2 months, foregoing all other pleasures in order to buy their 'starter kit' from their preferred supplier. Only to find that their coil, which they have budgeted to last 2-3 weeks breaks, gets gunked up or is a dud. Now, this dude or duddett goes directly back to smoking those disgusting stinkies. They do not even make it to the level of an RDA, RBA etc etc.
Thankfully the coils are getting better but this was a real sore point for me and I would feel really bad for these poor souls. It is also advisable to know what you are doing before attempting to rebuild a 'factory line' made coil as it could be 'dangerous'.
I have thus made it my mission to find every factory made coil and show folks how to rebuild them in order to provide a longer lasting vape and keep folks away from the stinkies. There are so many ways to skin a cat, not that I would skin any cat, unless their fur was going to provide some sort of miracle wicking material, and yes I have tried it, cat fur does not work, but I did not skin the cat to get the fur, I collected it. Anyways, that is a whole other post.
Rebuild of The Nautilus Mini BVC Coil (NOT THE RIPTRIPPER METHOD) Much bigger vapor clouds, no flooding, no dry hits, Not a BVC Coil
1)Drill out the 2 holes on the side of the coil to 1.5mm. Use only the 2 holes that go directly through. the other 2 holes come up against a sleeve inside the coil chamber.
2)Plug the two other holes with some tightly packed cotton, we will not be needing these. Make your coil, using 26 gauge kanthal, do 9 wraps around a 1.4mm drill bit. Then insert the long ends through the top of the coil. Pull your coil down to the bottom of the chamber while holding on to the pigtail leads until you can see the inner coil diameter line up with the circumference of your previously drilled holes.
Before inserting the bottom ends of the bvc chamber, push a 1.3mm drill bit through the holes you previously drilled, while making sure to line it up with the center of your coil that is now inside the chamber.
This would be the view from the top:
3) Once you have seated the coil, insert the rubber grommit at the bottom of the chamber and then insert the pin, this will secure your coil in place(can be seen in 2nd picture).
Thread some cotton through the lined up hole of the inner coil and the drilled holes, making sure to not leave any gaps between the drilled hole wall and the cotton. On a side note, I like the cotton to not be too thick so as to impede juice flow, but also not too thin so that juice comes flooding in through your drilled holes.
4)Wet the cotton and give her a twirl around the coil post:
5)Reasemble the Aspire Mini and prepare for the most awesome vape ever. Flavor is amazing, but what got me the most was the amount of clouds that came forth from this device. Even better than the standard BVC coil, and I surmise this is due to the large chamber within the coil and the fact the 1.4mm thickness of the coil within the chamber allows for more air flow than would be common in a standard BVC coil. Totally amazed at the outcome.
You are now ready to vape and live free once again and it doesn't cost you an arm and a leg. The coil worked out to 0.9 ohms and using 15 watts pushed so much cloud out I had to open the yacht hatch to get some air in.
