 |

Greetings:
The construction of my RV8A (RV7 and RV9 are the
same) the Rudders Top Rib swings OVER the top Rib of
the VS. There is suppose to be a "Gap" between the
two Ribs so that there is no interference (rubbing of
them together) as the Rudder is moved.
My question is - how do you set this Gap up ???
It seems to me that the Rod End Bearings on the Rudder
Spar need to be screwed into the Rudder Spar the "
Final" distance so that the Gap can be set up properly
BEFORE the Rudder Skin is finally riveted to the
Rudders Top Rib (R703) which sets this Gap. My
understanding the dimensions for screwing the Rod End
Bearings as shown on the Drawing 7 is only
"approximate" and needs to be fined tuned later = this
could change this Gap distance.
Or if one marks a center-line on the flange of the
Rudders Top Rib and aligns the pre-punched holes in
the Rudder Skin directly over the "center of this
line", does it Guarantee automatic clearance and a
constant Gap distance when the Rod End bearings are
set to their "Final" screwed-in distance ??????
The Orndorff Tapes show the Rod End bearings installed
in the Rudder Spar (no Rod End Bearing dimensions
given) and mounted to the VS and the Gap set by
bending Up the Rudders Top Rib (R703) to parallel the
VS Top Rib. Maybe I am missing something. So what
worked for you - set the Rod End Bearings "approx" or
align the pre-punched holes in the Rudder Skin
directly over the marked center-line on the Rudders
Top Rib flange and THEN rivet the Rudder Skin ????
Once the Rudder Skin is riveted to the Rudders Top
Rib, the Rudders Top Rib is fixed and can NOT be
readjusted to get the "correct Gap" later.
Appreciate your help, Garey Wittich
