Started with the harness shoulder strap support.
It is going to lift up the shoulder strap so it run’s down from that support point to my shoulders.
This whole structure sit’s on top of the spar carry through.
I still need to cut some of the vertical tubes, so that it’s flush with the top of the fuselage. I also will create some bracing with 1/2″ tube Then two, one size down, tubes go in the two verticals, high enough to lift up the shoulder strap. And when the plane is parked, I can just pull out the tubes so it’s not obvious it is there.
