Where to repair my studio shutter?

[Soomuu]

Very nice work and interesting to see all the details of the leaves. Not for the faint hearted, though. The shutter design is smart, but has a built-in weakness around the holes.
I think a better project for entrepreneurs in China, or elsewhere, would be a range of simple iris clamps to replace the lost lens flanges

Thanks Steven. I agree with the weakness around the holes in combination with material used.
As for the Iris clamps, What Roger mentioned with Chamonix having made one already.

Chamonix has your iris clamp. http://www.chamonixviewcamera.com/irislensboard.html

OH yes, I remember seeing this some years ago. With all respect to Chamonix and their investment in tooling and large format in general, it is strange that a very simple item is priced at exactly the same level that the original iris clamps command!
