After being sick most of the week Mitch and I finally got some riveting done this Thursday evening. We started witth the gear tower on the left and right fwd skins and got most of the way through those rivets. I find that we could have left the fuslage upright and it would have been easier to do with several I could have done myself. I plan on turning the fuselage back upright until I just can't go any further and then flip it over.
Most of the -4 rivets are set on the fwd side skin which is where the gear towers tie in.
