I have noticed several older sailplanes with some play in the wings.
They don't seem to pull into the fuselage and have a few thousandths
play so that the wings move fore and aft, slightly. Can this be
shimmed? I know from working on L-33's that they come from the factory
with shims. Is this an acceptable fix for older glass ships?

Jack,

I suppose there's no one answer, as a lot depends on the ship. For
example, I've owned gliders from both Grob and LS, and the approach to
adjusting out this play was very different. For example, the bushings
for the drag spars on the fuselage of the LS8 are threaded and allow
some of this play to be removed without additional shims. The Grob
Astir had a similar arrangement.
