Hey guys, still a newbie here, but I speak electronics so I have an advanced newb question. I took apart an atty and did my research here on the forum. I understand coil wrapping and wicks and pretty much all the basics...except airflow. I'm trying to design/build my very own atty, and I've drawn the simple diagram, but can someone please explain where the air comes and goes (well, I guess I know where it eventually winds up...hehe) when you draw on a carto? I know this is modding 101, but I don't think I'll get it until someone can explain this in idiot language for me. TIA.
