Finally figured out why my shutter curtain timing was always off by a hair
I was working on a Pentax K1000 from a local shop, and the second curtain kept lagging just enough to overexpose the right edge. For months I'd been adjusting the spring tension, but it never stuck. The tip-off was a tiny bit of old, sticky grease on the curtain roller axle that I only saw under my bench light at a certain angle. Cleaned that off with some lighter fluid and a cotton swab, and the timing snapped right into place. Anyone else miss a simple cleaning step that turned out to be the whole problem?

Oh, that's so satisfying when you finally spot the one tiny thing causing all the trouble. Been there with stubborn mechanisms myself.

Honestly that sounds like a pretty minor issue for months of work. A tiny bit of leftover grease wouldn't cause a huge problem on most cameras. Maybe the timing was just finally broken in from all that adjusting.
