Fitting the longerons to the aft fuselage - 9 hours

As usual. It's been a very busy week leaving not a whole lot of time to work on the RV. I am teaching ground school one day a week but frankly its lots of work to write power point presentations. Did I mention its not easy to teach...You really want to know a subject, try teaching it.

I rechecked the fit of the longerons just to make sure I was happy with everything. I need to make very small adjustments for the vertical stabilizer bars. (Longeron openings are a tad snug). I also double checked the ends of the angles for trimming.


Now that I'm happy with the fit of the F-710B angle I riveted it to the bulkhead.

Next step I cleaned up the longerons. I filed the openings for the horizontal stabilizer bars so they weren't so tight. I filed down some thickness on the flange that was trimmed back on the aft end, and I also timed the aft length so that it sat flush with the tab on the aft bulkhead.


All ready to install on the fuse and then to flip the fuse over.


Next I was then ready to join the aft and center sections. Slow and easy wins the race.

It occurred to me after some time that the F-704 Bulkhead does not sit "in" the angle. I used some spacers to lift up the F-704 bulkhead as it sits on "top" of the angle.Then the side skins and everything else started to fit quite nicely.
