Chris,

 

During my 9th condition inspection I decided to do something about the vibration in the stick and the loose hinges.  

 

No wonder the "looseness" had increased, the Teflon had flowed a bit but the original hinges had not worn at all.  The hardest part was removing the teflon spagetti from some of the hinges.  The finger-twisted reamer actually did no more than clean the gunk out of the old hinges except for one loop end that yielded a wee bit of metal.  I then made hinge pins out of 3/32 SS welding rod and replaced the pins in the elevator, ailerons and flaps (the tightest pin fit of all), lightly lubricating the insertion operation with lithium grease.   I decided to reuse my old hinges since they didn't exhibit much wear (when compared to new hinge material) and, although the fit was close, very little resistance was added. 

 

 

Now I can more clearly identify the remaining vibration that is rpm dependent.
