Large combs are easy; punching for them is not. A document this thick has to be punched in several passes, and every pass has to align or the holes will not sit on the tines. Use the machine backstop and keep the batches identical. Consider whether a wire or thermal bind suits the document better. See plastic binding combs, comb binding machines and thermal binding.
