Ive just purchased a manual ream/stack cutter that has a minimum cutting depth of 30mm. Ie. the closest the backstop can get to the blade is 30mm. I could manually move what im cutting closer to the blade but just wondering if there is a common workaround to keep it all square. Like some accurate 30mm block of some sort that you can put in there to shift the paper forward? Any ideas or experience with this?
