To cut up the side pieces;
- cut up a piece of board so that is 115x56mm,
- then make a mark 38mm from the left edge at a) and from the right edge at b)
- cut along the shown line.
- make marks at 38 mm once again, at c) and d)
- measure 46mm from a) against b), to get x),
- cut from x) to c)
- lay the pieces on top of each other so that c) and d) are at the same place
- cut at d) along the edge that differs.
… these form the side pieces.
The remaining pieces are rectangular:
2pcs 122×32 mm, with a centered hole on both – these are to hold the pinhole.
1pcs each that are 42, 46 and 56 mm – and 122mm wide. Ooops one more that is 42! (top&bottom)
53mm wide pieces, 2pcs each of 20, 21 and 29.
One more piece 53mm high, that is 75mm long and has a centered rectangular hole of 65x24mm – to allow the film to see light through.
