Once again, I am trying to get my Polaroid 405 back to work with my Calumet CC-400. I've just spent some time using it on a Toyo field camera, and I wish I could use it on the Calumet. It seems to be perhaps a quarter of an inch too thick to fit into the spring back of the Calumet.
After reading an older thread here, I contacted Jose Pueyo, the expert at Calumet. The thread had suggested using springs with the part numbers 105797 and 105798, however, after sending photos of my camera to Jose, he said that it had those springs already. Unfortunately, he had no firm suggestions, though he thought that washers under the spring to give a little more clearance might work. That would also require a longer screw to secure the spring.
Has anyone else had any successful experience with this problem? I would greatly appreciate any suggestions, keeping in mind my limited knowledge here!
