Has any tried filing air slots on aTank atty????

[alongo]

Has anyone tried making the airslots on the bottom chrome ring of the ego atty bigger? this would let more air in and make the draw easier. My only 3 atties, 2 r and 1 LR and seem to get a little hard to draw on after awhile. cleaning helps some, but if i take them off the battery its really easy to draw thru. If I had a couple more i'd experiment on one. let me know if you tried this. Thanks.
Mine always seem to line up with the batery button and my finger blocks it off half the time.

As the threads wear from going on and off the battery, they do cinch down tighter and restrict airflow a little. - And yes, somewhere in the massive ego-t thread there were a few posts about it. You can do it with a file or a rasp fairly quickly, but I did one of mine in about 1/10th of a second with my band saw.

I usually just push a safety pin up though the hole in the battery end. What this does is push up on the coil itself, when it's laying to flat it can restrict the airflow. I do this carefully of course.

when you made it bigger was it better??????

It let more air through.

My experience was just like yours. I thought the atty was getting clogged, but I noticed it was easy to blow out and the draw was fine when it wasn't on the battery. So, I buzzed the the two air notches on the bottom of the atty a little bit deeper with my band saw. That atty now lets more air through.

I tried filing the slots, even added two more slots for a total of 4 slots and couldn't tell a difference. What I did that actually did improve airflow was to drill two small 1/16" holes right below the threads on the battery itself. The battery I did this to had a tight draw and whistled a lot and it drove me nuts.

I used a small pointed grinding bit on my dremel to create a starting point for the drill. Drilling on a rounded surface is difficult to do without creating a small divit for the drill to start in. Just be careful not to drill into the center battery contact.

This actually did improve airflow and almost completely stopped the whistle sound. Interestingly enough, my other battery draws fine and does not whistle as-is.

EDIT: for clarification, there are two sets of thread on the ego batteries. The threads I'm talking about are on the smaller end on the inside. As it is the air has to travel thru the threads and between the center contact and the atomizer threaded end. As far as I can see, that center hole that sits right on top of the battery contact is the only place for air to travel thru. I'm surprised they work at all.

No. That's not where the air flows. They are just like any other 510 with two holes above the threads on the atty. Then, the air has to come from some where. it comes through the two rectangular slots on the bottom of the cone. If those slots cinch down too tight on the battery, it restricts the airflow. Notch those deeper and more air can make it in the cone to feed the two holes above the 510 threads on the atty.
