here is my cut and shut camera,it has a slit shutter,and will accept any m42 mount lens,uses 35mm film ,as its wound on, something has to move to get a picture either the subject or the camera.this took a little over a day to make.and wieghs just under 12oz without lens or film.this is a cross between a fed5 (body)a zenit e (42 lensmount)and a spinner dolphin 360(shutter concept)i did consider going for the full 360 functionality but that would increase the materials list, this camera would be easy enough to make again,and to have the ability to make super panoramas with any lens i like on an object that looks the part would be awesome, as it is i guesstimate that it can do 210 degrees on about 60mm of film.(hold the lever and turn the camera)

well half of it ,the arm and the 2nd prism are missing. the prism that is there has had it.  unscrew the cam lever visible through the lens mount to release rf assembly

Step 4: Speed selector

the speed selector can be tricky to disassemble,
A. A3 grub screws and then unscrew
B. then unhook the spring.
C. remove the screw that goes through the spindle. then the brass piece will lift off. 
D. remove the selftimer lever reverse thread screw.
E. 4 screws in the front and 2 on the top hold the shutter box,the rest comes apart easily.
F. the only gear needed to remain in is the spindle that stablises the film sprocket  thingy. its secured withe a leaf spring which i replaced with a circlip

What is the point of this camera? Will it create usable images? I'm quite bemused with all the engineering and the end result.

flatterd that u call it engineering . what would u call a usable image. whats the point,thats a bit harsh.

Do, what are the results like?
crazyg (author)  Kiteman1 year ago
test images are up :-)
Kiteman crazyg1 year ago
And they are fascinating!
crazyg (author)  Kiteman1 year ago
dunno yet. :-)
Kiteman crazyg1 year ago
Oh, you need to sort that!

Very nice. The camera has got plenty of style too and the finished job looks tidy. Have you got any pics to show us?
crazyg (author)  Machine1 year ago
test images are up :-)
crazyg (author)  Machine1 year ago
thanks your too kind. Im just coming to the end of a rotton cold. i promis to get some film in it , the images should be up in a couple of days

I had a basic Zenit SLR film camera back in the 1970s. The shutter was a focal plane cloth shutter, what you called a slit shutter. It had an accident that was probably my fault. I had to repair the shutter and add some new ribbon to drag the two sections across the back. I used the scan rate of an old TV to calibrate the shutter. A couple of things on that camera were copied from German camera designs out of the 1930s.

the slit i was referring to, more of a hole than a shutter,the wonder of no moving parts!.
cloth shutters i find tricky to reassemble ,i managed it once with a kmz zenit start, all the rollers are housed in a cage which all the body sections are attached to.(i got one with serial number xxxxx666) much more all thumbs friendly.
calibration with a telly sounds ingenious how does that work?
my zenit c (s for sync flash socket) is like a shadow of my fake leica II, they both like to tear film and have dubious loading methods.

A shutter can be calibrated within limits by photographing an old analog TV with a cathode ray tube. It has been a long time since I read about it and tried it, but an analog TV scans 525 lines per second, which I believe is the full screen top to bottom. If you photographed the TV screen at a particular shutter speed, say 1/60th second, the resulting photo would show a portion of the screen illuminated with the screen image and the remainder of the screen black. The black portions are likely to be above and below the section that is illuminated. You examine how much of the screen is illuminated with an image and compare that with how many lines out of 525 should be illuminated at that shutter speed. This is what I remember, but it may not be completely accurate. Here is a link that should help.

i was previously wondering if there was a method where you didnt have to get film processed ha ha wishful thinking,
thats a super link really demonstrates the communicative power of drawing.
thanks
