Shoutout to the old repair manual that showed me how many shutter parts are actually stamped steel
Found a 1973 Nikon service guide at a flea market, and it blew my mind that over 60% of the components in the F2's curtain assembly are just stamped and folded. Anyone else get surprised by how much basic metalwork is in these 'precision' machines?
My grandpa's 1968 Pentax Spotmatic was the same. I had to fix a slow curtain and found the whole advance lever assembly was just three stamped plates riveted together. The claw that catches the film sprocket? A single piece of steel, folded into a tiny hook. It's kind of beautiful in a cheap way, like they solved a hard problem with a simple punch press.
Yeah that stamping thing is wild, right? I had a similar shock taking apart an old Minolta. You learn to check for stress lines on those folded edges, they crack there first. A lot of those parts you can actually flatten and re-bend if you're careful, saves hunting for impossible spares.
My 1972 Konica had a stamped film counter gear that cracked. Tried the flatten and rebend trick lilyt90 mentioned, but my hands are too shaky. Ended up making a new one from a soda can. Looked terrible but worked for another decade.
