The day my book press slipped and I blamed the wrong glue
Last spring I was flattening a batch of 12 covers in my garage workshop in Portland. I stacked them in the press like always, tightened it down, and walked away for 20 minutes. When I came back, the top three boards had shifted and left these ugly diagonal creases across the middle. At first I figured my PVA mix was too thin, so I switched to a thicker paste and tried again. Same result. Turns out the press platen had a tiny wobble from a loose bolt underneath, not the adhesive at all. After I tightened that bolt and added a cheap cork liner, the creases vanished completely. Has anyone else had a tool failure masquerade as a material issue? I spent a whole weekend chasing the wrong variable.
