I have 400 feet of Eastman 5222 in the freezer. I received five re-loadable cassettes a few days ago so only now am I thinking of how I'm going to load these in my not-light-tight-enough darkroom. Can someone tell me the diameter of the hole in the core of film spools like this? With no flanges I'm afraid a wobble will cause the film to telescope into a disaster. I'll do something in a box with a changing bag type of sleeve arrangement.

thanks,

s-a
