Why doesn't anyone use stainless steel in their custom flashlights? I was just looking at a pill container I bought about a year ago for 5 or 10 bucks. It's stainless, has been carried in my pocket with all my keys for a year, and still looks good as new. Out of curiosity, I popped a 123 in it and it's almost a perfect fit. The top screws off, the threads are nice and smooth, it's o-ring sealed. The whole thing is light and easy to carry. The bottom might make a nice power pack for a mod. Here's a couple of pics, I put it on my scanner so they're not so great but you can get the idea. It looks nicer in person than in these scans.
