Dear David Gagnon, It is unfortunate that you chose such a public forum for your complaint but perhaps I can help. I am familiar with the Schmoyer dial, having coveted one since reading the article in the 1960 Book of Projects for the Amateur Scientist by Scientific American. The design has sparked a life long interest in sundials. Years ago, an acquaintance of mine purchased a set of Schmoyer castings but, to my knowledge, he has not completed the project (machining or assembly). Would these be useful as patterns to reproduce the missing pieces? Let me know if this is worth follow up.
