I’ve made two improvement to the in-situ book conservation fixture. First, the sliding arm is now machined out of a solid 1 x 1″ block of aluminum, so it much more rigid. The second is the front bar is now made from a 1″ rod of Delrin, much more paper friendly than the previous aluminum one, and has a larger diameter. History and more images of an earlier version. Available for purchase here.
