I'm building a feild camera like the Tachihara, Winser, etc. I've located several sources for small (5/8 or smaller diameter) brass knurled nuts several places on the net. But I can't seem to find anything larger. I'm looking for something to use as focusing knobs like the traditional ones for these cameras. Anyone have an idea where I can find these?
I've tried all the usual places like Small Parts, Reid Tools and McMaster-Carr.
