Quite interesting video showing how a spinner is made on a lathe.

Real knowledge is to know the extent of one's ignorance.

I saw them making spinners for Beechcraft years ago, while touring Globe
Engineering, years ago in Wichita. I production they were using a bearing
roller with a smooth radius face. I think the face of the bearing was
polished carbide.

They were turing out about one a minute, and claimed to produce them for all
the aircraft companies in the Wichita area. I know their tooling rack had
for or five dozens of tapered steel cone. One was required for each
different type.
