"Somebody pinched it! And what I say is: them 'as pinched it, done her in" Eliza Doolittle
So, I'm a simple man. My cameras will be in one of two, at most three locations in the house.
I got the yen to convert my old Voigtlander Rollfilmkamera to a zoom pinhole - while the Skopar on it I think is capable, the shutter is way too violent in its action, thus causing all sorts of blur in photos. So, a pinhole with the shutter in T or B wouldn't actually make things worse... and as this isn't a self erecting folder, I can keep the bellows in for a wide angle, and pull them out for a longer 'focal length' for the pinhole. All I had to do was to take off the lens.
And to do that, my friends, I had to get my hands on the camera. I figured it would really be in one of two places... but no. I found some other stuff, but not this camera. I checked the other places it may be in, in descending order of likelihood... but nothing.
Grrr.
And I discovered that checking the same spot three times, with increasing care, won't turn up a large thing like a camera
So, I say, them's that pinched it, done her in! _________________ -Jussi

Ah, just done some calculations... with the pinhole around 50mm I get f/128, and at the infinity stop, f/288, and at the close focus stop f/325.
My Gossen reads directly f/128, and f/288 is close enough to three stops from f/90. I think I can do this just need the sun to come up
If I use my other pinhole (mounted on a K body cap) I get f/180, f/480, and f/542, which get into the zero image tiny pinhole territory. So I'll leave that for now.
My special pinhole mount is a plastic film cap, sized to fit a standard Compur shutter barrel, so all I had to do was to pop it in, and do a couple of quick measurements. _________________ -Jussi

at 55mm by Nesster, on Flickr
So, some success... at 115mm the pinhole covers the entire 6x9, but at around 55m there's a nice round image due to vignetting. You can see the threads from the bellows. But I'm not getting the sharpness I see in the Zero Image pinholes, maybe this hole is still too large.
Oh - film is Ilford HP5 Plus, D-76 1:1, Epson 4490. _________________ -Jussi

They look pretty good to me. The sharpness difference may have more to do with how close to perfect your pinhole is. The Zero Image ones may be laser shot.
Aluminum for your pinhole? Brass? Could be some itsy-bitsy burrs ... _________________ Paul
