Today the two sides of the rudder become one. I read in the manual that it was recommended that we use some fuel tank sealant to hold the trailing edge together during riveting to achieve a straight trailing edge. However, I failed to order the sealant so I decided to use "Gorilla Glue" because it claims it will adhere to metals. The part I missed was that Gorilla Glue expands when it dries so my trailing edge is not as sharp as it could be. If I were to do this again I would order the sealant and not use the Gorilla Glue. In images 2 and 3 (below) you can see that I used some blue masking tape wrapped around the yoke of the pneumatic squeezer to protect the skins. This would not have been necessary if I had waited to roll the leading edges until after I riveted the skins. It worked out OK on the rudder but it wasn't nearly as easy when I tried it on the elevators.
