Very nice pictorial!

Curious; how do you use a 6-32 screw in a 4-40 hole?

I'm starting on a BH P-47 and my ailerons were already hinged and pinned as you say your T-28 was. But my T-28 control surfaces were not prehinged and came with dry CA type hinges stuck in the slots. However the control rods for the elevator were shiny new while the ones in my P-47 are covered in fairly heavy rust and will have to be replaced. (just noticed this last night)

But overall I'm impressed with the two BH planes construction. I know I haven't put anything so complex together and have it anywhere near as nice. The factory doing this clearly has the process refined.

Regards,
