Today I spent a couple hours putting the forward fuselage gussets in place. They are unique to the -7 vs the -7A. The tri-gear plane rear landing gear are mounted just forward of the center section. Since the -7 is a tail trager, there is a gap here that need to be reinforced using these gussets. They are attached to the sides of the fuselage with 5 bolts that need to be match drilled. The gussets also line up with the bottom wing attach bolts.
I lined everything up and then drilled the holes to #40 and then enlarged for the AN3 bolts. I prepped and primed these and then attached them to the fuselage. The whole interior will be painted with my interior paint, but it’s good to prime all the parts especially mating surfaces.
I also sent a bit of time working on the panel attachment brackets. Since I’m using twin Skyview HDC screens, I need to move the Vans panel supports inboard. This requires making some custom brackets to attach the panel to the sub panel. I received a shipment of L stock from vans that worked perfectly for this.
I decided to wrap up the center section bolts that are used for the tricycle gear. In the tail dragged version the bolts need to be put into the center section.
The bottom bolts were difficult to reach but everything is now in place and torqued.
I also placed the remaining two cover supports on the sides of the fuselage, forward of the center section.
Next up is to wrap up the exhaust hangar modification. And to drill the wing fuel attachment bracket to the sides of the fuselage.
