I haven't used a scroll saw before, will it let me cut to a given depth and stop? That's important, as you have to glue the pages to the back cover too, and you don't want to cut through that. It also requires being able to start the cut away from the page edges. I guess I just assumed that a RotoZip or router type device were my only options for that. Well, aside from the trusty Xacto knife.
