Might have to retire my mini nautilus

[David Wolf]

I heavily used my mini nautilus from about November 2014 up until last March, and still use it lightly. It became my "stick in breast pocket" to go out for dinner setup with an istick 20W, or my "I need to go visit someone for an hour" setup, while I used my IPV Mini 2 more at home or long visits at my parents. I used to really enjoy the istick/mini nautilus setup, with only more gripes about inconsistent coils and some gurgling, but I have noticed in the last month or so, I'll fill it up with Boba's Bounty (expensive in Canada, up to $14 cnd for a 15 ml!) and even with a new coil, in 2 days of little use the juice would darken (oxidization) and almost become unvape-able (harsh throat hit, harsh taste,etc).... Expensive juice is just too expensive to have a tank darkened like that. I used to sometimes vape the darkened juice down, dump it out, and fill it up, and it would just darken again quite quickly. It sucks.

I presume you're using the new vertical cotton coils and the old coils perhaps performed better for you? I've seen the same thing, backflow of darkened liquid after a day or two. I'm using the GS Air Tank now with 1.5 ohm dual coil not the 1.2 ohm vertical cotton and the backflow is less.

I find it usually takes about a week of fulltime vaping for the liquid to brown up quickly with each refill--that's one indicator to me that it's time to wash the tank and install a new coil. Now that these coils are truly cotton filled, there tends to be some liquid feedback from the cotton into the reservoir. So, when the cotton gets brown, the liquid darkens much more quickly.

Try two days to see darkened backflow from the vertical cotton coils when vaping darker liquids on a mini.

I agree....I wish I could find a round micro wire brush that I could insert into the vertical coil and give it a good scrubbing. I have yet to find such a beast.

Wallgreens or CVS have long throw away brush's that come in a 5 pack.

This is what I did with my dual coil nautilus coil explanation under pic

View attachment 477303 this is a 1.6 ohm dual coils Aspire head that I gutted completely and drilled with a small size bit.

I drilled all four holes and pressed a tooth pick into one of the two opposing holes after

cutting the tip off the tooth pic and then did the same with the other opposing hole.

This leaves me with 2 wooden plugs plugging 2 opposing holes.

I then slide jewlers screwdriver thru the hole and thru a small coil that I tied and put

grommet and pin back in.

I just pull out the wick every 2 days and dry burn the coil and put new cotton wick back in

and ready to roll again.........

made a cotton wick and slide threw and leave tails about one half inch long and litely tuck

the tails down into

the nautilus base and wet the coil good and put it all together and it works good. Single

horizontal coil. Whatever size you can fit in the hole will work, I used 28 guage with 5

wraps---comes out to .5 ohms------fun fooling around with this.

nice work. The current standard coil for the nautilus is the 4 hole wick 1.8 ohm vertical cotton coil. 2 of the holes have an internal barrier that forces liquid around the wick. Good flavor at the expense of gurgling on hot days outside and darkened liquid backflow from the coil after a couple days vaping.

one reason i only vape clear or slightly colored juices
