Hi Fellas,
Well it came in ...
...but I can't get the shutter to open. While I don't know how to operate film cameras I can only assume that when I cock it and press the shutter the "click" should be accompanied by a shutter opened for a fraction of a second.
Well, you picked one hell of a camera to learn camera repair on.
1. It isn't going to work right without a battery. Since the thing was designed to take PX625 mercury batteries, and since it is now illegal for anyone to make or import them, this presents a problem; it isn't that difficult to solve though. A couple of companies make 625 alkaline batteries that they sell to people who don't know any better. They won't work right (1.5 volts won't work right in a camera meant for 1.35 volts). HOWEVER, you can punch the middle out of the POS alkaline battery, ream it a bit, and you have an adapter that will let you use #675 zinc/air hearing aid batteries -- those WILL work, and they are (relatively speaking) cheap as dirt.
2. Canonets are very susceptible to sticky shutter syndrome. This is what happens when excess oil slowly spreads onto the shutter blades over a period of years and then dries out. The drying lubricant becomes sticky and tar-like and sticks the shutter blades together. The usual solution is to flush or scrub it out of there with naptha.
To do that, you will first need to get a lens wrench with fine tips. A cheap $15 lens wrench from ebay won't do the job, as is, but you can grind the tips down thinner and narrower. Once you have a wrench that works, you remove some lens elements and this gives you access to the shutter blades, which you can then scrub (gently) with naptha on cotton swabs about 50 times (no, I'm not kidding -- 50 times, firing the shutter between each of the swabbings). This should free up the shutter and get the speeds very close to accurate -- well within the acceptable error range.
To get it
really accurate you need to get a shutter timer and you need to take the whole thing apart and clean each part individually, by hand. Then you need to lube it,
very sparingly, and keeping oil well away from the blades.
