Has anyone on the list tried to make a screen? I did the other day -- for a non-Pentax piece of equipment. I used a piece of glass from a 6x6 anti-Newton Ring slide mount. It worked very well. The glass is very clear but has very fine surface 'etching'.
I guess there are notches and indentations in the camera screens that might make this approach difficult. But even glass can be shaped using the right abrasives and tools. The surface would need to be protected by tape while this is being done -- clear Scotch would do. The glass could be shaped with small toolmakers stones and the like. I hesitate to mention Dremel because the diamond wheels I've seen were all too coarse for glass.
