Chris,

During my 9th condition inspection I decided to do something = about the=20 vibration in the stick and the loose hinges.

No wonder the "looseness" had increased, the Teflon had flowed a = bit but=20 the original hinges had not worn at all. The hardest part was = removing=20 the teflon spagetti from some of the hinges. The finger-twisted = reamer=20 actually did no more than clean the gunk out of the old hinges except = for one=20 loop end that yielded a wee bit of metal. I then made hinge = pins=20 out of 3/32 SS welding rod and replaced the pins in the elevator, = ailerons and=20 flaps (the tightest pin fit of all), lightly lubricating the=20 insertion operation with lithium grease. I decided to = reuse=20 my old hinges since they didn't exhibit much wear (when compared to = new hinge=20 material) and, although the fit was close, very little resistance = was=20 added.

Now I can more clearly identify the remaining vibration that = is rpm=20 dependent. =20
