Many have built dual-coil setups on their SubTanks. Below is probably the most popular config. There are many YT videos detailing the process. Good luck!

The only thing i have is 1/8 drill-bit. anything smaller will be the mini screwdriver that comes with the subtank mini which i do not know the diameter lolThat's the full sized.... Deck is wider. Would need a pretty small ID to go that route on the mini, the rba in question![]()

Is the small blue screw driver 1/16? I tried making a coil out of the screwdriver, and I was thinking it is too small to fit any cotton in!1/8" is almost 3.2mm. 1/16" is almost 1.6mm... Two 3.2mm coils in a STMini would be tight... Good luck!

I shall give them a try! Thanks for the info!I think the bluedrivers are 2mm. Use it if they fit! Vapers used 1.6mm microcoils for a long time. You can wick 'em...
i guess it depends on ur definition of micro, macro.I donno guys, I just dont get it. I built many micro coils, even rebuilt dozens upon dozens of coils for CE4/5's but when I started messing around with RDA's I started building much larger coils that would hold a lot more wicking material. I tried the micro coils in them and everytime I started chain vaping I would get a burnt taste. To me. if you have the room for a bigger coil, why build a micro coil. What is the allure to it for yall?
I have 3 subtanks (one is the Subox tank) and I have noticed that some of the "replacement" rings are not the same size by feel. I noticed when I changed the color rings to id the flavor in the tanks that it doesn't leak, it seeps out. The base was clean and dry but there was still juice coming out. It was from the lower ring where it meets the glass. It just barely had the "pressure line" around the bottom of the glass. I cleaned it out and used some waxed thin dental floss under where the ring sets and replaced the o-ring and reset the glass. After doing this I have not had one issue with seeping.
Someone above posted that he had rust in his airflow base, I would take those back to where you got them from as stainless will not do that and those would be clones built of a different type of metal.
this wont stop any juice going into the air control base, just out from under the glass. The dental floss will just increase the size of the washer, too much is almost worse than not enough so start lean.
If your airflow is getting juice, this is more than likely a wicking problem. Not enough wicking will allow the juice to go from the tank into the airflow valves as well as vaping it down to the point where there is a positive pressure inside the tank forcing juice into the RBA cap.
If it is leaking I would give her a good bath and bulk up the washers (or replace them if you have spares).
