Aluminum shaft with captive ring

Captive ring

Lathe experiment #2, machined out of a piece of solid aluminum rod. Basically, the ring is stuck because it was carved out of the rod. A collaboration with Matt Stultz.

    @Marty
    Sure, it’s just a trick- you start by machining down two sections of rod, leaving a ring-sized separation between them, and then you turn the tool on an angle and undercut it until it is free :-) . You can make one, if you want!
