Just imagine that the business end of a 60º center,which is normally round,looks like a pyramid with 90º corners on it. This is not complicated. Don't over think. The corners will bite enough into softer materials to allow light turning . This was used much more often back in the old days,when chucks were non existent,or too expensive to be affordable. Ivory turners could make chess pieces with a center like I have described. Brass candlesticks could also be made. The simple system would be very fast to change pieces of work in. Faster than using a chuck of any kind at all. So,in old factories,it would have been a good thing to use.
MANY years ago I bought the very LAST can of white lead that the paint store had in stock. It was being outlawed in the early 70's. I tried to be careful to not get it on my fingers,but probably did any way. Once you put a little dab of white lead on the end of a piece of work,it had a way of getting around on the work quite a bit!
I still have that can of Dutch Boy white lead,though it's probably dried out. Or,may have gotten tossed in one of my wife's clean out campaigns.
