Nicholas,

Here is the schematic for the 4x5 negative carrier. You only need to change the dimension for the actual film size (actual, not stated) to make any carrier you need. This one is set up to use the water jet to increase the opening from "4x5" to "5x7". The existing pins will be reset to maintain the film registration or we will make new ones.
