Ch. 6 - Fuselage assembly - Part 9

F-28 installation (1.1 hrs)  

The main thing to know about F-28, is that its front face needs to be 5.9” from the front face of F-22. There is an additional change to the plans, requiring one ply of BID at 45˚ over the wooden doubler, F-22, sidewall, and upper longeron.

Pure epoxy brushed where F-28 will go

Right doubler and F-28 floxed in place
