REFLECTOR: AN111 rudder cable bushing

[Brian Michalk]

I've been having people over to inspect the plane, and the last person 
wanted castellated nuts on all things that rotate such as cable/rudder 
horn, cable/rudder pedal, pitch trim and control stick.
I purchased drilled bolts and castellated nuts for everything and 
decided to switch out my thimble in the rudder to an AN111 bushing.

Now, it's not clear to me how the bushing is supposed to keep the steel 
cable from jumping out of the AN111 bushing.  Is this design correct?  
It's just a little interesting to me.
