So I tried a quick search and only found one other person with the question and it didn't really answer to me. So I picked up a used B&J Orbit 4x5 monorail camera and have been starting to teach myself how to use it all. I picked up a Polaroid 405 packfilm holder because I've been shooting a lot with my land camera prior and have a good amount of film to use while I learn. I'm just having trouble because for the life of me, I can't get the 405 to slide under the ground glass like a normal sheet film holder. It's just too large. The only work around I've been able to rig is if I undo the springs holding the top of the ground glass so it just kind of hangs there, then jam the film pack in just using the tension from the bottom half of the springs and shoot like that.
I don't really like having to undo my springs, risk bending or breaking things for my camera to work, so my question is has anyone else conquered this issue yet? Is it possible to buy longer springs for the ground glass back and replace them? Am I just going to have to live with it? Thanks! Any help would be greatly appreciated.
