I've seen a fair amount of modifications made to rda's and I think it's something I'd like to try. I've seen attys with only 3 air holes on each side drilled out to make one slot on each side (which is what I'd like to try) but I'm not sure how one would go about doing this. I've also seen the "variable airflow" lips at the top of the juice well on attys completely taken down to the rim (also would like to try) and although it is a very cheap and easily acquired clone, I wouldn't want to mess anything up and have to order a new one. The main thing Im aiming for with this atty is directly enhanced airflow to the coils. See I bought a wide bore chuff cap (which I hoped might improve airflow) but since the atty has limited airflow due to the three tiny air holes on each side, the air flow feels really tight and leaves much to be desired. I have access to the tools I might need and even know a few talented machinists who could do the work for me, but I'd like to have a little advice from anyone who has experience with this before I go ahead and start chopping up my atty
