@foundthefault@tech.lgbt @deviantollam@defcon.social Maybe friction-weld a tapered shaft to a bearing ball? If I were trying that, I'd spin my lathe at 2K RPM max speed in one direction and have a fixture for the ball going 12K RPM max speed in the other using my toolpost grinder, and hope that 14K RPM difference was enough. But I've never friction-welded metal, only plastic.
