Another @arsimago #labbox fuckup. The first roll was Film Ferrania P30. Maybe there was something in the film that caused this? So this time I tried Tri-X. It’s about as common a film as you can find. And this one was worse. More than half the roll blown. EDIT: I think I may have figured out what causes this. When I disassembled the box to dry, I discovered that I had the reel put together wrong. Right side connected to the left side of the axel and vice-versa. I made sure the entry points were matched up, but looks like that wasn’t enough. So I’m going to try again in a couple of days, making sure the reel is correct
