Door galley is installed....finally! Still waiting on the Southco latch for the countertop. I ordered one from Ebay and the seller sent the wrong part; they are sending a replacement.
I installed riv-nuts (rivet nuts) in the door sheet metal. Here is a pic of a riv-nut:
Riv-nuts come in a few different materials....aluminum is easy to install if you can live with aluminum threads. I could only get steel ones so this is what I went with.
I have an installation tool but these can also be installed in a more "pedestrian" fashion using a screw of the proper size. Simply drill a hole the same size as the riv nut OD (you want a sung fit), insert the riv-nut into the hole and swage in place with the tool or just by tightening a screw really tight. The screw method requires a tight fit of the riv nut in the hole to assure that it doesn't spin when swaging.
I splurged a bit in a moment of weakness and bought black oxide hardware from McMaster for the friction hinges, right down to fancy "black Luster" cap nuts. The cables are used bicycle shifter cables (Shimano stainless SIS wire).
