Hello, everybody. We’re finally here at the end of our Contax 2 article. In part 2, we took apart the rangefinder and removed the shutter mechanism from the chassis. It’s not an easy task to take this camera apart but the real fun begins here in part 3 where we repair the broken shutter and adjust it until we get something acceptable. This is probably the deepest most repairman will bother to open this camera to, any further disassembly will be too time-consuming and should only be done when absolutely necessary. The shutter’s clockwork mechanism should be left-alone as much as possible. A very good flushing of the gears and its parts is usually more than sufficient to get this camera back into smooth operation. If your shutter mechanism is corroded then a good ultrasonic cleaning will be the best option for you. Just don’t forget to clean it very well afterwards to prevent your shutter from corrosion due to residual salts or acids from the solution. Some liquids use citric acid or ascetic acid and that will eat-away at the metal and leave crystal-like white deposits as corrosion (“white rust”). Use distilled water to prevent mineral deposits. Use alcohol or naphtha to do a final flushing just in case.
Does this look fun? Depending on who you ask, this can be a fun activity or a nightmare. The shutter of the Contax is a marvel of its time. I have never seen a shutter that is more intricate that this. Just think about it, it stood the test of time and it’s still functioning well into its 80th year. They really don’t make things the way they used to.
