don't use super glue for the second nut!!!

the next step, we'll need a PVC tube ( I didn't have an exact diameter tube so it was sawed  on one side , heated and putted on the same size  bead )

Next - the beads need to be glued to PVC tube ( super glue )
and attached inside the torso ( magic smooth epoxy )
This joint allow the hand to move in all necessary direction

Very cool!  Now I get it! The pearl bead rotates around the cotter pin. BTW I've always called a "spilt pin" a cotter pin. I love the connection inside the arm also. Very smart!

Thank you so much for taking the time to post photos of the process.

Thanks! Frankly, I didn't know how this pin should be called so my version isn't correct 
Thank you for the right name
