Tonight I spent about 45 minutes riveting the bottom skin to bulkheads. I set about 50 rivets, most came out well. I’ll need to drill and redo one where there is too much of a gap between the sheer clip and the j-channel. I need to clamp down the end of the clip so it doesn’t lift away when I rivet. I’m going to finish riveting then come back to it. If I can get another 2-3 hours in tomorrow and Friday, I should have this step done by the weekend. Riveting with the gun is a noisy process, so I need to be mindful of my hours.
