Well, let me start with fact, that I really like Arca Swiss camera. It was my entrance into LF, and served me very well. But recently I started using barrel lenses, and I needed something more sophisticated for a shutter than a lens cap. I used lens cap together with 10-stop ND filter, but it drive me crazy. So, Sinar Copal shutter it'll be. My idea was to use front standard from Sinar Norma that is smaller than Arca 171mm front standard. So I got auxiliary standard from e-*** for next to nothing. Then I asked a friend, who have a milling machine for adaptor. I also ordered custom made bellows from Custom Bellows in UK. Here are few photos of "present state" of modification. I need to sand blast adaptors and make few modifications in lens plates to accommodate both pins from the shutter (auxiliary standard is narrower that regular front standard). Then everything needs to be anodized.
Here are few photos from current state of the project.
Cheers,
Marko
