Posted for "Jim Nordin" <panelmaker@earthlink.net>:

  I asked someone at Lancair years ago about this problem and his (name
  withheld) answer was simple.
  Misalignment is a problem with two hinges on the same elevator. Put one
  hinge on that is the length of the elevator attachment (26.75") and make
  sure it's straight ... not wavy in any axis. That was a statement from a
  previous support person there.
  
  I think the Teflon is the best fix for installed hinges. And you might take
  a look to make sure the best job of alignment has been done. The fit can be
  improved without damage to the paint job if you're careful.

   I've done 30 odd hours in my recently completed 320 (small tail) and
  notice
  grey streaks (aluminium I think) coming from the outboard elevator hinges .
   Everything seems tight - has anyone got any ideas what may be causing it
  and
  the best fix.
   
   Thanks
  
  [It's strange to hear it reported in a plane with only 30 hours on it, but
  it's a well-documented phenomenon.  The grey streaks are most likely
  aluminum,
  as you surmised, resulting from the wear the hinge knuckles are seeing from
  rotating around the hinge pins.  The most typical fix is to ream the
  knuckles
  and go to the teflon tube hinge pin sleeves.  Search the archive for
  "airframe
  vibration".  One of our members sells the teflon and hinge pin kits... I'm
  sure he'll jump in.   <marv>     ]
