Friends, I have more and more onesies to do with critical parts of movie cameras. Aperture plates, the part of the film gate behind which the film gets exposed, intermediate parts, lens mounts, ground glasses, ground focusing prisms. Be it that a prism surface become finer or the contrary, be it that a lens turret should be made flat on the back side.
For that I need a lapping plate or disc. Looking out I am finding a few dealers, even OEM, that ask prices such as CHF 760, about even with the US Dollar. 150 mm diameter, 15 mm thick, cast iron, grooves grid. I mean, what? A piece of iron, grooves milled, lapped flat on a machine in a quarter hour? Can anybody help me understand what is going on? I can’t afford such madness.
