Spent 3 days fighting a warped text block before I checked the press
I was trimming a 500 page novel and every single pass came out crooked. Swapped blades, recalibrated the cutter, even blamed the humidity in my shop near Pittsburgh. Finally on day three I realized the press plate had a slight bow from when I dropped it last spring. A flat file and 20 minutes fixed what 3 days of head scratching couldn't. Anyone else got a tool that fails in a sneaky way like that?
