Final fitting of the landing gear weldments - 6 hours

 After reading up on the forums and blogs, Now is a good time to check fitment of the landing gear weldments with the centre spar (F-704) . Once I assemble the fuse making adjustments to the landing gear become much more difficult.

First I drilled out the rivets for the three nutplates in the forward spar ends. I noticed on initial fitment, that these will get in the way later. Once the weldments are permanently installed, it will be super easy to install the nutplates....again 


Now begins a very very slow process of fitting the weldments to the center section. The instructions specifically indicate that holes may be filed a bit open to allow the bolts to fit. The process is slow since I test fit, remove, file, test fit, remove, file, over and over again until all bolts fit.

I am extremely careful to not file the close tolerance bolt holes if i can avoid it. So I started with the placing those bolts first securely and then working/fitting all the other holes.





Once I was happy with the weldment fit, I was ready to assemble the F-704 center spar to the center section in preparation to fit the fuse all back together.
