Recently I got from Liquid Light an Agfa Isolette in a swap:
http://f295.tompersinger.com/cgi-bin/Blah/Blah.pl?b=cs,m=1129673906
In the meantime I finished and blackened the inside and made her lighttight, but now the shutter problem ::)
I'm not very good in drawing, but here are some drafts to show the problem:
As you can see from topview1, the cover is concave, so I have to construct a flat plate with the pinhole located on the backside of the plate (pinhole not drawn), see topview2
This plate will look like frontview1
Two possibilities for a shutter:
frontview2 and frontview3 ::)
What would be better and do you have any other ideas?

Alternate suggestion -- transplant a rotary shutter from an otherwise toasted box camera, or just fabricate one (if you have one to look at, you can probalby make one with only a little more effort than the sliding shutter above). You can even decide whether to make it T (no return spring, stays either open or closed, wherever it was when you took your hand off) or B (with return spring, closes without pressure on the release). You'll need a piece of sheet brass, a lever of some kind, one or two pieces of fine wire (a steel guitar string should work very well), and a few fasteners...

I decided to go for "frontview2"
Here are some photos of the shutter and the finished camera with a "shutter protection"
The full story can be found here:

I'd be tempted to trim the shutter piece -- at least round off the corners on the pivot end so they don't get into the frame if you don't rotate the shutter far enough -- but otherwise, that's about as simple as they get...

Looks great, Taco! There's always something to be said for simplicity.

For some reason I was not able to access the "full story". Lots of other nice stuff to look at on your site, however.

I could . I think you were just to afraid of the following sign:
If you ignore it and scroll down, you normally could see it

I'm not quite sure what I did before, but it worked fine this time. Operator error, to be sure.

Not yet! Ijust transformed it, but with the daylight in northern Europe and the "good" weather I didn't have time to test her ??)
