Rudder is nearing completion

 

I have done the trailing edge of the rudder. I was obsessing about it for several months, then I did it in afternoon.

I followed the plans, except for using mushroom set to finish off all the rivets. I was doing gradual backriveting on them and things looked well. When I tried to use mushroom set, the edge started deforming almost immediately. I stopped and continued with backriveting. 

I think it turned out well, except the small part where I used mushroom set, which is still OK.
