I have a book charkha. I’ve watched this video from Joan Ruane (I mostly loathe video, but she comes highly recommended as a spinning teacher and it was efficient and informative, so that’s okay.)
She recommends using Vaseline to keep the wheels spinning easily.
This article from Spin Off magazine talks about spinning wheel oil:

I don’t have either of those right now. Would sewing machine oil also work?
