As mentioned earlier
we plan to eventually mount a camera in the tip of the Vertical
Stabilizer. This is an idea fellow RV-10 builder Michael
Sausen showed me, and I really liked it. In order to get
cables to the camera we needed to drill a hole in the VS-1006 Top
Rib. There are lightening holes in the other two ribs, but
not in this one. I consulted Van's regarding the modification
and they indicated it shouldn't cause any problems. So, using
the recommended hole size (3/4") for the 5/8" conduit Van's offers I
used a unibit to drill the hole.

Here is the finished
product, along with the conduit installed for a test fit.
Originally I planned the hole a bit further back, but then noticed it
was directly between the cutouts in the flanges. These ribs
are already pretty flimsy between these cutouts so I felt moving the
hole forward between the flanges would provide a little more support.

Here Angela is
formulating her plan of attack for the night.
|
First step is
finishing the R-1015 stiffeners (7-3 step 1). They're all cut
to length, but still need the triangular portion removed fron the
angled end. These will eventually be clecoed together with
shear clips like the ones at the top of the picture.
|
Next step is
to debur the R-1005 Rudder Horn (7-4 step 2), and then countersink 4
holes in it (2 on one side, 2 on the other.)
|
7-4 Step 3
has us clecoing the R-1005 Rudder Horn to the R-1004 Bottom Rib
Assembly. This is so we can match-drill the 6 holes in the
Rudder Horn to the Bottom Rib Web. Once done, we use these
new holes to cleco the assembly together. Here you can see
the assembly and the countersunk holes from the previous step.

And this is
a shot of the whole assembly after 7-4 step 3.
