REFLECTOR: Plumbing the Spar

[Epstein Lawrence Jay]

No-

The wings should be on, all plumb & level, incidence gauge on, while you fabricate/install the strakes. The strakes are what hold the spar/wing at the correct incidence.

>> Slow building Hooper here.  When we installed the spar everything was level, on the money.  The vertical line on the spar bushings was also on the money.  The fire wall was and remains dead nuts perfect.  The wings have been on for three months and we're about to mount the lower strake on the pilot side.  I rechecked the levels, and all is exact.  Nothing has moved.  However, in placing a level against the spare (front, outboard), and plumbing a line down between the spar and the wing to the center or the earth, it appears that the outboard part of the spar is twisted a bit, not in plumb, rotating aft.  My bubble level error may be from unevenness in the spar surface.  I am also assuming that twist will  be induced by the weight of the wings.
