I've become a little spoiled getting to use the plough to even off the edges of books. It's a little intimidating at first but once you get the hang of it the smooth edge is addictive, and takes some of the pressure off of binding it perfectly. Basically you just have to mark what side you want trimmed, put the text block between boards that are ever so slightly bigger with the margin to be trimmed exposed on the side facing you, and line it up in the press with the spine side facing you to begin. (Trim the foredge last.) The hardest part is getting it in the press with the margin to be trimmed evenly exposed/not tilted at all, etc. Though I will admit, I still can only plough in one direction, unlike Gavin who zips back and forth and at twice my speed. Someday!
