For the subtank mini rba section.
Last build was with 26g 2.5mm 9 wraps came out 1.1Ω.
Put wick through coil I like mine snug to slightly tight in the coil.
Put chamber on threading wick through then cut each end about half an inch above the chamber.
Fold the ends of the wick over the chamber and push back and tuck down into chamber so the bottom of the wick ends are touching the deck.
Then juice the coil and wick and with a thin tool go between the wick and the side of the chamber and gently easy the wick away from the sides.
This has been good for me after many others were not.
For me doesn't like the wick touching the juice holes and didn't like the wick going from the end of the coil and straight down to the deck.
Once I had more horizontal wick out from the coil ends then bending down to the deck it liked that much more.

Try cutting the cotton to the length of the airflow base, not deck, then fluff each end carefully with something small and pointy, trim the excess fluff cotton that is pulled out...then do the rabbit ears, screw on chamber and carefully tuck the cotton down on each side...prime wick with juice (not too much) then with a large needle or similar thin object, carefully clear the juice channel area without putting too much pressure on the cotton...this has worked for me using 26 gauge wire, spaced coil, 5-6 wraps, 2.4 mm ID. I don't usually go over about 23 watts with the STM...oh, and don't go too tight on the cotton in the coil
What the other's have said makes sense. I would emphasize that the wick needs to be cut at the right length. If there is too much cotton packed into the wells then the liquid doesn't flow and a lack of vapour and dry hits will occur. You could try starting a fresh and cutting it long and see how it goes. Then re-wick but after screwing the drum back on cut the cotton about 5mm above the top, preferably with a pair of very sharp scissors. That seems to solve the problem. Less is more !.
Another problem, though probably not important, is how wide you cut your wick (or how much you're starting with if yore using something like cotton bacon which you don't cut from a strip so you have to guess) . I use pads and i cut a strip about 4mm wide for a 2.5mm coil which allows me to pull and twist it into the coil without any real resistance.
You will notice the difference if your wick is packed too tight in the wells. A big difference in vapour production. So much so that if you don't know what's wrong it would be quite frustrating. You'll turn the watts up, you'll change out the battery, then you'll think it's an airflow problem or you're just not sucking hard enough.
If the liquid can't flow to the coil then the coil has no liquid to vapourise. And that's what's happening.

This is what I did about ten days ago and not one dry hit since... Eliminates the need to be so picky with the wicking. In other words, you don't have to position the wick just perfect as to draw the juice in. This LETS the juice in without relying on a particular wick position or shape.

I run at 20 watts with a 1 ohm coil. Maybe I'm wrong about this but why run a .5 ohm coil at 35 watts and above when you can obtain the same thing with 1 ohm at 20 watts and not go through your battery as fast. I have tried both the 1 ohm and the .5 ohm and for me the experience was pretty much equal. Please, anyone, chime in and educate me if I'm wrong about this.
I did what Bob did on my wife's mini. She kept having problems burning the wick. Not sure what was going on, as both of ours are coiled the same and pretty close to same wicking. She had problems but mine works just fine though she does like a hotter vape.
I run mine at 25W .5 ohm two hole airflow, she was running 27W .51 ohm 2 hole airflow. After drilling she's hitting it at 35W airflow wide open and loving it. So glad I found this mod on the subtank mini.

I carefully dremeled (with a small disc) the juice channels about 15-20% larger on mine and it works great. Wicks are well fed now on high vg juice. Never a dry or burnt tasting hit, and never floods.
I picked up another Subtank Mini today in fact and dremeled that one too right out of the box, and it works great.

Nice Work... Looks nice and clean. I have a dremel but wasn't sure in my ability of how it would turn out. I felt confident in drilling the holes. But I admire your skill with the dremel...
Are you using twisted 32 gauge for your coil? It appears twisted to me in your post. I'm using the 3 wires of twisted 32 gauge and building 1 to 1.2 ohm coils... They're working perfect for me at about 18 to 20 watts...
I'm running twisted 26 5 wraps at .5 ohms, 25W on a stock STM, and I don't have issues. Same build for my wife but she always managed to get burnt hits pretty much same coil at .51 ohms so I drilled hers and no problems since Friday. We got or STMs a week apart, I can only guess the there is a difference between the two in tolerances.
For the juice I use, it tastes better to us in the range we are vaping , though it is even better on a mech at around .4 ohms in a dripper. Then I get a hint of lemon on the exhale which I don't get on the STM.
