Could someone show or explain exactly how Chip Hyde designed this elevator pushrod bushing at the tail end of the aircraft?

It seems as if a brass sleeve is glued onto the end of a pushrod. I think it is slid into another brass sleeve that is secured into the tail end of the airplane. The brass sleeve is inserted into a sleeve at the tail end of the airplane and slides back and forth inside this sleeve.

Is this correct? What materials are used in this bushing assembly?

I stole this picture in another thread from Scott Anderson (PatternPilot) with Performance Model Aviation. I hope this is okay.
