bellows for large format camera

Step 3 Cut up and line up

since this is just a demo bellows i elected to make a simple square one but if you want you can make a tapered one for that old fashioned look(or to reduce the size of the front lensboard which is why alot of old cameras look that way. it also allows the bellows to fold up in a more compact space)
the sheet was 22x28 inches so i started from the long edge and scored in 11 inches worth of lines cut it away then divided the sheet into 4 equal bits(7x11).
lay one side in front of you score lines up .
cut off a piece of hockey tape and slide it under the long edge of the sheet so 1/3rd of it is under the edge glue side up(keep it even)
press the sheet into the tape so it sticks well.
line up the next sheet so the lines exactly match the first one than slide it out so its covering 1/3rd from the other side of the tape.(leaving 1/3 in the middle uncovered).
cut another piece of hockey tape and cover the seam (so the tape is face to face) press it well to make the tapes stick to each other and the card.
repeat that step untill you have the four sheets joined with a 1/3 inch cloth joint in between each.( use 3/4 inch tape for small bellows and 1/4 inch spacing).
now to join them together to make a tube lay the assembly down with the score marks up fold the number one sheet and the number 4 sheet towards each other( they should lie 1/3 of an inch away from each other) slide a strip of tape glue side up under the two edges .
when its lined up press the edges into it then cover with another tape strip, press well again because all this is going to be strained around and a bad tape join may pop and ruin the whole thing.
