Brief Description: Rivet Hat Channel/Seal Supports to Sub Panel.
Lets rivet the Forward Upper Fuselage. I have not riveted anything in months it seems. First the F-697 Hat Channel and F-643-1 get riveted to the F-768A Center Sub-Panel. Bucked all these. Easy, when using this cool Vice/Clamp thingy. This Vise/Clamp thingy is attached or stowed in seconds with large wing nuts underneath.
Second, the Seal Support Angles get riveted to the Sub-Panel.. These can all be squeezed.
