Yesterday I worked on riveting the aft three bulkheads. Each of them are made up of several parts, including doublers.
I tried a few techniques to clamp parts, and to support the rivet squeezer. my first two rivets were perfect, but in the wrong holes! I got distracted for a minute, pulled out the wrong cleco, and set a rivet in the wrong hole. I set a second one before I suddenly realized my mistake. Fortunately I was able to drill and remove both without any damage.
I found it easiest to clamp the parts to the bench, with some carpet as padding, then hold the squeezer the two hands to set the rivets.
Today I was able to finish the job, the aft three bulkheads are ready to install now.
