How to mill down grand

Unless something magical comes out, I think I could be happy with these forever.

That's what I ended up using today. Because of the shape, it was tough to mark up, so I just kind of eyeballed it until I was close and then just took off another couple of layers. It was a piece of cake. Since it's aluminum, it gets hot rather fast, particularly if the abrasive isn't really fresh and sharp. All in all, though, with cool down periods, it took about 15 minutes. I took the bottle, delrin cover, and button out, de-burred the grind by hand with a piece of 600 grit sandpaper, and ran it under hot water to get any errant shavings out. Slapped it back together and put one of my Odins on it with a .94 ohm double coil using 9 wraps per side with 30g Kanthal. Works perfectly.

If it's flat to begin with, you should be able to do that with a file in a couple of minutes. Sit your file across both sides of the lip, use long strokes, preferably with a file wide enough to do the whole surface in one pass. No power tools required, very little chance of buggering it up.
