Task: Riveted the skins onto the rudder skeleton.
a longeron yoke from a -9 builder at my airport. I used it to
get to the rivets that attach the R-901 skins to the R-904 bottom
rib and R-710 brace. They are tricky to get to due to the angle
of the brace. After some time adjusting the rivet set I was
able to get them squeezed. I wasn't, however, able to reach
the forward most bottom rivets. The plans call out for LP4-4
blind rivets but they are 1/8", so I need to find a pop
rivet 1/8" dimple die.
right skin is clecod to the skeleton and I've set most of the
rivets along the R-902 spar. I used back riveting tape on top
and squeezed most of the rivets. I've found that the tape keeps
the manufactured heads very clean. I had to drive a few of the
rivets that my 3" yoke couldn't reach.
Here is the left skin in position to be riveted
to the spar.
I then inserted the R-903 tip rib and clecod it into place.
There are several different sized rivets used here so I took
a few extra moments to make sure I was using the correct sizes.
I've gotten in to habit of putting tape along
the bottom of the rivets so the yoke or bucking bar doesn't
scratch the under structure. I squeezed all of the rivets to
the aft of the 710 brace.
Here I've finished riveting the left skin to
the counterbalance skin and tip rib.
The skins have been riveted to the front spar and the bottom
