bellows for large format camera

Step 4 Folding

folding while this step is simple it takes a long time so settle in a comfy chair and get to it.
fold the nearest edge to you away from you( bend it so it creases nicely)
then turn the tube 90 degrees and fold the top edge towards you then 90 degrees fold away,90 degrees fold towards and so on.
as you can see the card wants to bend on the lines we scored earlier thats good.
when you have folded the top move to the next row below and fold it opposite of the one directly above .
repeat the pattern until you get to the bottom.
this will get hard to do with smaller bellows but go slow and dont try to rush by doing more than 1 row at a time. also if you decide to turn it over and start at the other end too make sure you keep close track of what one bends in and what 1 bends out.
now some of you are probably thinking why didnt he fold the sheets before he taped them together?... anyone? no?
well ill explain it anyway . if you fold before hand it almost never lines up accurately so you get out of alignment and the joints are under unequal strain and fail.
