I mentioned this a couple times on this forum and to others in PMs, but never got around to taking/posting pics.
Here's how I modified the
Ijoy Exo-S RBA to work in the
Eleaf Ello tank. This is the regular Ello tank, I don't know anything about the other Ello tanks like the T, Duro, Vate, etc.
I got these tanks with my
Pico 21700 Kits and the
Pico 25 kits. The RBA fits the tank with 2ml or 4ml glass. The modification would be the same regardless.
The reason for the modification - You can't use the exo-s rba in the Ello as-is because the oring seal at the bottom of the glass completely blocks the wick holes on the RBA. You'd be vaping burnt wick because the Ello's oring/seal hugs the rba very snuggly right at or right above the RBA's wick holes. You'd be licky to get a drop of juice to them even with high PG juices.
The tool I used to make my new wick holes is a
manual nibbler tool, however on my next rba mod I'm going to try it with a dremmel instead and make the holes a bit different. But using the nibbler tool for this project is easy. Downside is the end result isn't very pretty lol. But functional. The nibbler cuts by squeezing so it has a tendency to bend the the material it's cutting a bit (however this didn't affect the threading). I'll be taking a Dremmel to this one at some point to smooth the edges out a bit & make it look better.
Top/inner view with the original wick holes packed tight with cotton. I did this to plug them up just in case some juice does get to the holes, which would result in
eliquid eventually flooding the RBA and leaking out of the airflow since I'm no longer going to be wicking down to the stock wick holes...
Pic with the chamber screwed on. You can see how low the wick holes sit. If I were to install the oring/seal the wick holes would completely cover and seal-up the wick holes (sorry, forgot to take a pic with the oring/seal on it)...
Here's the chamber screwed on with my square wick holes I made with my nibbler tool. Not great looking, but it does the job. You can see how the nibbler does bend the metal a bit, but it hasn't affected the chamber's ability to screw onto the deck...
With the RBA wicked up and the tank assembled (2ml glass). Notice how even the bottom my my own wick holes are covered by the tank's oring/seal. The RBA's stock wick holes are covered up completely...
With 4ml glass (chimney extension) to show how well the chimney threads screw into the top of the RBA chamber - seals very well...
Been vaping on this for weeks now without issue.
When I do this on the next RBA with a dremmel, I'm going to make the wick holes about 1/2 to 3/4 the size that my nibbler tool makes.
No other modifications were made. You just make one wick hole on each side if the chamber. But you have to make sure you make the holes to line up with where the coil holes are going to be. So just screw the chamber on the deck, mark the chamber where the original wick holes are below it, then take the chamber off and make your new wick holes where you marked the chamber.
Pretty easy. Just make sure you wash your chamber real good after you make your holes, regardless of what method you use to make the holes.
When you install the RBA in the tank, you have to remove the bottom tank oring/seal, screw in the RBA, put the bottom tank oring/seal on then put your tank together, in that order. You can't put the RBA into the tank with the oring/seal in place...it won't fit in that way.
Now if there were a oring/seal from another 25mm tank I could replace the original Ello seal, one that would not go the whole way up to the RBA, that would be best as no modding would be needed since the juice would be able to freely get to the stock wick holes on the RBA. I bet there's an oring/seal on a tank out there that would work, but finding it would be a real
