There are mock-ups in many Zone System books. I sat down and cut chips off a printed step wedge. Then followed the layout in Minor White's booklet. You really don't "need" to precisely find the 10 actual print tones. Find any scrap print with some smooth tones that you can cut small chips that divide "visually" into 10 different values from black to white.
