A little dowel rod held the 16 mm spool. I made a little gate for in front of the pinhole, also out of cardboard, I think. I had to estimate the diameter of the pinhole, which was basically too small to measure. Black felt taped above the hole on the outside of the box "closed the shutter" while the frame was advanced. From outside of the box I estimated how much I had to turn the rod to advance one frame.

I made a pinhole film that used only a cardboard box and pinhole, just like you use in photography.

Tom Comerford is really the expert on the pinholes for Bolexes. He produced a little pamphlet on it a few years back and a number of lovely films. He teaches at the School of the Art Institute in Chicago and may be willing to answer your questions via email.
In my own experiments I used an extension tube that I capped with black wrap with a hole in it made with a straight pin. I measured my focal length (the distance from the front of the lens/black wrap to the film plane) and knew (roughly) the size of the pinhole because my straight pins were .65mm (they are for sewing and thus precise). Then I used the following formula
f-stop=focal length/pinhole diameter
I ended up with an f-stop around 90 so I shot outside on a sunny day with plus-x reversal and had very good results.
Hope this helps,
Kathryn
