Re-made the F-711D angle and fitted the Aft Deck - 7 hours

I started fitting the aft deck onto the fuselage and noticed that I wasnt quite getting the holes to line up with the 7/16" measurement on drawing #18. The holes are very close, but the sit just inward from the dimension given. I looked all over to be sure my fitment was correct and yup...things are just slightly off. No way I can squeeze things together to make the 7/16" line fall within the center of the holes on the Aft Deck. 

Looks like I will need to run with this. I'm not worried as it is so darn close, and I certainly have enough edge distance. I drew a red minimum edge distance line on the longeron just to be sure.

Now...because the rivet line is just a bit off from what I originally thought, I re-checked my F-711D angle. One thing that was bothering my is that the angle did not nest nicely into the longeron inside radius. Well, I am getting quite good with fabricating these angles so I quickly made a new one and shaped it so that it will nest into the longeron and yet clear the rivet.


I then fitted the new angle and it looks fantastic. Only took my 20min to make a new one. So time well spent.



 

I backdrilled the angle, Deburred and primed. After some dry time I riveted the angle on using my handy alligator squeezer. 


 No I took some time and carefully adjusted everything so that the plane was level on both the longitudinal and lateral axis. This was a tedious process but everything looks great.


 

Now I can begin the process of fitting the aft deck.
