Anodized aluminum would be nice. But I'd have some comments: 1) The thinnest "generally available" aluminum is 1/16 (0.0625"). 1/32 (0.03125") can be had, but is not so easy to find. I haven't measured my dark slides (I'll try to remember to do it tonight), but I'd bet they're not more than 0.020.
2) You really will need something like a brake or a horizontal shear to get the thin sheet metal cut with real accuracy and smoothness. You'll need to do that, as machining a thin sheet-metal edge is not so easy. 3) Home-brew anodizing can indeed be done, but it is neither (a) the easiest, nor (b) the safest procedure you've ever undertaken in your life. There are recently some products available (name escapes me) which allow "cold anodizing" of aluminum. Essentially it's a chemical stripper followed by a coating that penetrates a couple of thou into the metal. It is non toxic, and, I've heard, quite durable.

Black anodized aluminum would be very nice. _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
