How to Modify a Polaroid Land Camera to Take 35mm film

Step 8 Light Proofing The Left Side Hole

So after you drilled the hole cut a piece of leather about 3/4"x 1/2". You can either cut the hole before you glue it to the camera or after it is up to you they both work. Cut the hole about a 1/16 too small so that it stretches around the dowel for a tight seal. After the hole is cut glue the same black fabric to the back of the leather. once it dries force the dowel through the leather like in pictures 6 and 7. Make Two of these, one for the inside one outside.
 
Because the metal has a funny bend and gets thinner for some reason we need to put a little piece of leather there so the other inside piece is flush and tightly sealed.
When you are happy with your piece dampen them lightly put the gorilla glue on them and clam away. Do Each  Piece of Leather Separately Be Patient! This part needs to dry fully! it takes the most stress of anything on the camera and its a weird glue, leather to aluminum. when it is dry put the clay piece back in, force the dowel in and you are almost ready to get cranking.
