We interrupt this program to announce that I'm an idiot. (Some of you may have already suspected as much, but let's not have everyone speak up at once.) Last night I separated a bezel/reflector assembly for the first time. Partially because of ignorance and partially because of high gravity beer, I reassembled it incorrectly, without the lens and O-ring sandwich. After spending half of the day trying to take it back apart, it finally acquiesced. Then, just as I had all of the parts lined up correctly, I fumbled and dropped everything in such a way that the lens got trapped between the falling steel bezel and a granite table top.
CRACK!
So I broke my first lens. Now I have an order in with Unique Titanium for a new glass lens (at least it wasn't sapphire!) and I got a spare reflector, in case I muck something else up.
