The shutter was a piece of card hinged with black tape and held closed by tape and rubber band (when not in use). However it de-laminated when I was trying the camera out so it has been removed for the time being.
pdf and dwg files for the various format can be found here
http://86.20.28.106/temp/. The files are Drawing24, Drawing35 & Drawing70.
The formats are 70x24, 35x24 and 24x24. Although I have only made up the first in the series at present and they are quite basic. With the 70 I toyed with the idea of having the pinhole biased to on edge or the other but haven't tried this out yet. Still refining the design\use.
They should be printed full size onto A4 paper. With adobe reader you may have to uncheck the "shrink oversized pages" to paper size to get the right size. Particularly with the 70 model.
Glue the printout onto thin card (I used a cereal box) or print onto thin card.
I would recommend that the film aperture\pinhole and lead through's for film winding are cut out of the card before any of the other cuts are made. Once the remaining cuts are made the camera will fold up into a box. Secure using elastic\rubber bands.
I have not included any visual instructions at this stage but will try and sort some out before the weekend as I am away. (I plan to take one of these with me to play\waste some film with.)
The film is fed from one cassette to another as per the pin hole instructions at the start of this thread.
My wind on mechanisim is a 8 mm diameter dowel with a slot in the end and for the 70 I use two full turns to wind on to the next frame.
If anybody has any question about these then I will do my best to answer them prompty.
Good Luck.
