This day we continued on the next page 07-03 of the manual. We skipped the step 1 because we needed the section 6 assembly that we left for later (we are waiting the shipping of a damaged part replace) So we start doing the steps 2, 3 and 4 in the same page that consist on riveting que upper hinge and the step 1 of page 07-04 mostly of them with a hand squeeze rivet. Tip. One member on the team will squeeze the rivet and the other will take an eye checking the correct allignment all the time.
