Forward Spar Work

I set my first rivet! I had to rivet the elevator hinge bracket around the elevator bearing with six rivets squeezed with my pneumatic squeezer. This was fairly simple and turned out looking pretty good. 


First rivet of thousands!

After that, I worked at shaping the reinforcement angles that will attached to the forward spar. I had to round off the ends and then bend them 6 degrees, according to the plans. This was pretty simple and they turned out pretty well.

Next, I started work on the front spar. The front spar comes in two pieces. These were designed for use on the RV-8 and have to be trimmed down for use on the RV-7. I got the spar flanges cut back according to the plans and then created bend reliefs so I can bend the tabs appropriately. I used my flies to create these reliefs, but the plans say to use a drill and then files. It probably would've been easier had I used the drill first, but they still turned out pretty well.

Reliefs started... had to make them a bit deeper with my files 

To finish out a productive day, I cut two of the front ribs according to the plans. The aft flanges on these ribs have to be cut to allow them to fit around the reinforcing angles I worked on earlier.

This was a really productive day. I hope every weekend day will be this productive, but I know life will get in the way sometimes. I'm already finding myself losing time on the project to doing stuff with my friends. But I'm OK with that... I don't know how long I'll live in California and I want to take advantage of that while I'm here. This all just goes back to my insistence that I not have a set timeline for my project. As long as I'm working consistently on the project, I'll be happy.
