CH-640 Fuselage Hull - Stage One (6 of 206)




Square up the HT-frame and drill through the stiffener into the HT frame.  NOTE:  The HT fram is not actually square, the drawings show it as 88 degrees not 90, but I still used my square and found that it is very easy to lean it back the 2 degrees after drilling my rivet holes.
