Greetings all; The new encoder wheel I made last night, by fiddling with the math that determines the slot width until it has virtually no side wobble of the 1/16" mill at the inner apex of the slot, makes me ask a question about what is the best way to chemically blacken brass, hopefully with the intention of preventing reflections from the sides of the cut in the brass that might artificially broaden the effective aperture of the slot.
So, how does one chemically blacken brass? Ideally something that destroys any and all surface gloss, leaving a dead flat microscopic felt like finish. I considered paint, but at those angles of reflectance, even black paint might as well be glossy white. Plus I don't have any other than some ebony wood stain. ;-) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
