Here is one of the great watchmaking mysteries of the universe. It is what is thought to be a prototype gear cutting/screw cutting/ indexing attachment made to fit a Geneva Pattern Watchmaker’s lathe. The backstory is this: I bought this from Harvey Schmidt, who was considered one of the greatest watchmaking tool experts here in the USA, after Ted Crom. Harvey was a Star Fellow in the NAWCC for his contributions on watch and clock tooling. I bought many, many tools from him for my shop, and his stuff was always first rate. At the time I was looking for accessories for my 6mm Lorch. He had this on his table. He said he bought it at a Regional and tried for many hours to figure out how it was set up. As sharp as he was, he was unable to set it all up. He even researched the maker, to try to find out something about him. If he was an engineer, model maker, or horologist. He was never able to track him down. So, towards the end when he was breaking down his massive collection he decided to part from this device. I have spent many hours trying to set it up on my lathe to see if I could see what maybe he didn’t. So after nearly 20 years in my cabinet I have decided to let it go to the next generation of watch tool enthusiasts, who may finally be able to figure it all out! I wish I could tell you more, but I simply dont know. I even have the notes the original maker made in his project. They look like gear ratios and teeth count ratio tables that he was trying to translate into his device. Unfortunately Harvey passed about 10 years ago, and with him went a lot of knowledge on these machines. You can try to ask me questions – I will answer them all – many will be simply I don’t know!
