I've got my new calumet 4x5 camera this week, and while I'm waiting for the lens to arrive, I've decided to make my own camera bag for it. Here are some photos.
I started by creating a support frame made out of birch plywood. Basic tools... jigsaw, router, glue.
Then I carved the support holes and reinforced some joints with L-shaped brass
Next I've padded the wood with a crib filling, bought at walmart for about $3. I had some 3M spray glue around, which's proven perfect for this job.
The last step was to finish the support, gluing some fabric to the foam.
