OK,
I don't do spinney stuff but had a young man out to fix my water heater over the weekend. We got to talking and he's handy with a scrollsaw and the lathe. He was telling me about a couple of "Chinese Balls" he has made in the past. He said they are very time consuming and he had to index? them 64 times What is he talking about as I tried googling the balls and never found a picture only some tools from Packard WW? Me, not wanting to appear too stupid, just nodded as if I had a clue what he was talking about I was humbled 'cuz my 6 years of high school couldn't help out on this one, so, maybe I'm not as "smart" as I thought I was
