I was annoyed because my 510 cart wasn't fitting snugly into my 901 atty, when I noticed my Kobalt 8" long-nosed pliers (from Lowe's) sitting on the table next to my elbow.
So I put the last mm or so of the 901 atty in that circular void by the cutting blades, and very lightly squeezed the pliers. Not enough to see any visible change to the atomizer, just flexed it a little. Then I turned the atty about 1/4 turn, and did it again. No visible change, but now it holds my 510 carts so tightly, they're hard to get in and out! I drip through a gutted cart, so that's perfect for me.
Hope this helps someone avoid a little frustration.
And yeah, I know there's a proper tool for this but I don't have one. Can't even think of the name, off the top of my head. Pliers are easy to come by.
