I was a diamond setter for many years in Manhattan, back in the 1970's. For our cutting tools, used to cut the notches for the stones, in the metal prongs and channels, we lubricated and cooled with oil of wintergreen, not machine oil. It has a pleasant smell, and is not toxic when heated.
Thank you watching and telling us the fascinating story. I've never heard of the plants name "Winter green" before. I found that the oil is sold as aromatherapy oil in Japan. I'm looking forward to smell it. So, I have a couple of quetions I'd like to ask you. Was winter green oil major cutting fluid among diamond setters in Manhattan in the 1970's or was it a special method in your workshop? Did you used to use other plants oils such as olive oil? If you have time, I would be really grateful if you could give me your thoughts. Warm regards, Shou
Available online from carving, lapidary, or jewelry supply stores. Or can be fairly easily made. A Dremel or Foredom tool is a good start, and they can be quite inexpensive.
