Cigar presses are usually smaller than book presses, and often just half-arch, rather than full-arch. As such, they cannot generate as much pressure as a real book press. The one I purchased seems to have the compressional force of a typical copy press, which is adequate for the most common bookbinding tasks: firm adhesion of pastedowns, casing-in, and tray attachment when boxmaking. It wouldn’t be too difficult to modify a large C – clamp to make something similar.
Since they are lightweight, this one is about 30 lbs, they are great for teaching and travel. They usually have much more daylight than copy presses, again, useful when teaching, or for a secondary press. The main disadvantage is they only can be used for small format books.
Since cigar presses were originally used for pressing hand rolled cigars in long wooden molds, they often don’t have a top platen. I made a 7 x 9.5 inch aluminum one for this machine. Will I end up in conservation purgatory for drilling two holes in a historic machine?
