Riveting rudder skeleton
|Riveting counterbalance skin (Full size)|
We put on the upper counterbalance rib and skin, and put in the 6 rivets from the skin to the rib.

Here is another picture of the skin and rib, before we put in the rivets
|Dimpling rudder skins (Full size)|
I then dimpled the skins common to the ribs and spars.
|Angle clamped to skin to help hold it (Full size)|
The skin was too thin to get some of the holes dimpled, so I clamped an aluminum angle to one edge to help hold it. This worked great
|Cleco'd skin to rudder skeleton (Full size)|
Cleco'd the skins to the skeleton, before putting in the rivets common to the skin and counterbalance skin
|View of counterbalance weight bolted to rib (Full size)|
Here is the counterbalance weight bolted to the rib. Even though the grip length is right at a -10, there is still a whole lot of threads showing above the nut. I put 3 washers and there was still 6 threads showing. Yet the non-threaded bolt length is not showing above the hole. I think it is ok, just the style of these countersunk bolts, but I'll ask on the forums just in case.
