I own a few cameras with Synchro-Compur shutters ( Zeiss Contaflex lV, 35mm ) and recently took a look at an online video @ cleaning the lens. I was OK with what I saw ( could probably do it ) until the fellow started to disassemble the spring-loaded, innermost parts: he took each item out very quickly, and did not provide, say, a line drawing to go along with the video, that would outline the part, and allow it to be related to where it came from.

The work, itself, seems doable with proper tools and a good sense of Things Mechanical, but I would not attempt this work without a good, well-illustrated manual that clearly showed each step.

Some of the small springs in the shutter reminded me of similar items in the calendar mechanisms of wristwatches: they are not easy to manipulate and are delicate little critters, all-too-given to flying off into space...perhaps, never to return!

Oh: of my small collection of Old Cameras, the one that sure looks to have been the most nicely-made, is a Contax lla, with the Color Dial. I found it 25 years ago in a small Antique shop, an hour's drive away. What a Sweetie. It's not only jewel-like to look at, but the 1/60 th second shutter sound is almost...erotic!

Compurs/Synchro/Electro-Compurs/Copals/Prontor, all central shutters have the same origin, from old 6x6/6x9 middle format folders to 8x10", they all are the same basically, they just got more refined and bigger. I'm not an expert on this but I got most of them repaired again.
Yes, a well-light environment, tweezers and caution..those springs never return, haha
Contax are great, I also love my Pentax but really got in it with large format..a look onto a lit mirror-inverted viewig glass, almost in 3D quality, made me switch to 1920s' 9x12cm view cameras, then Linhof and later 13x18cm wooden cameras ..
and yes, without plans you are lost, as a non-pro..mostly its just mechanical repair, like this etc

radios/audio, for fun I build a tube amp from an old italian accordion amplifier, it became a Marshall JCM800-clone, sounded great..I dont think I could do that today again

Oh, cameras too? I am beginning to suspect the people on this forum might have a hobby overlap thing.

Mostly I keep to newer 35mm SLRs. Last thing I refurbished was a Praktica MTL3.

oh yes, that GDR Praktika was the one I learned for the first time in 1990, good cameras
