That clamp trick for pressing books I learned from a woodworker
I was having trouble getting my spines to form right on larger books, like the 10x12 inch ones I do for a local artist in Austin. No matter how long I left them in my press, the spine edges would come out rounded and uneven. Last month I stopped by a custom furniture shop to pick up some scrap hardwood for backing boards, and the guy there showed me how he uses three clamps instead of one on a glue-up. I tried it on my next project, putting one clamp at the top, one at the bottom, and one right in the middle of the pressing boards. The difference was night and day, the spine came out perfectly flat and square after just 6 hours instead of needing overnight. It distributed the pressure way more even across the whole book block. Has anyone else tried using multiple clamps for pressing or am I overthinking this?
