Hey JJ - any reason to be concerned about the tightness of the fit of
the pins in the bushings? I'd think you wouldn't want a shimmy in
flight. Is there any risk of that?

Some will experience what is known as the "clunk". That is the sound
you may hear when rolling into a thermal. It is the fuselage sliding
in the lift fittings and going "clunk". If you hear this you need at
least a 20 thousands shim on one aft lift fitting, determine which one
by measuring from the TE probe on the fin with a steel tape to a
common point on each wing, say the aileron cut-out. Don't be surprised
to find your prize possession is off by close to an inch! This will
tell you where to epoxy the shim onto one of the aft lift fittings.
Some will find their lift fittings are too tight which makes getting
the wing onto the lift fittings a chore. Clean the fittings and scrub
them with magic-marker, then put it together again. Then remove the
wing and observe the magic-marked pins. The shinny spots show the
interference fit areas. My ship showed a problem on the front end of
the forward lift fitting and the back end of the aft lift fitting. It
took months of working these areas down with emery cloth every time I
flew to finally get the wing to slide on easily. Believe me you don't
remove much steel with sandpaper!
