Brief Description: Finished riveting wins ribs to main spar.
I riveded ribs to the main spar by starting at the outside and working in. Once you get about half way through, you have the main spar leading edge reenforcement blocks in the way of the bucking bar. It would be very easy to damage these spar blocks. The manual talks about using tape to protect them from the bucking bar but I don't think that's enough. The first picture shows this piece of scrap of aluminum with double stick tape on one side. I would stick this scrap against the leading edge spar block for the bucking bar to rest against. Worked better then tape.
