Prepped and riveted the F-830B(PP) stiffener to F-829 Front Seat Floor.
Fabricated, prepped and riveted the F-832E Seat Back Hinge to the floor skin.
I recommend that anytime you're riveting hinge material, you lower the pressure on your rivet gun to the minimum practical, say 30 PSI or so, and use a 2X gun instead of a 3X or larger gun. I seem to re-learn this lesson every time I deal with hinges. The hinges are very soft aluminum, and it's easy to over-drive the rivets and cause ripples in the hinge. I over-drove mine, and the seat-back hinge came out slightly wavy -- not enough to cause problems with inserting the hinge pin, but just enough to annoy me.
The hinge has been cut to size, polished, and oriented on the floorboard skin.
Stiffener on bottom of floorboard has been dimpled and clecoed.
Hinge and stiffener riveted in place. The hinge is a bit wavier than I'd like.
