Gun Bluing

The control panel is now in place. A couple minor things to do like tie back the wiring with wire ties, but done.

About six months ago I learned that black bolts aren’t actually black…they’ve been blued using the same process that they use to “blue” gun barrels.

There are two different processes…hot and cold.

Hot involves chemicals and temperatures that I have absolutely no way of achieving here @ Casa del Peale.

Cold is easy, but involves toxic chemicals. I just bought a little container of the solution, dipped in my part, rinsed it off and wiped it down. Repeated that a couple times. Turned these zinc plated bolts black in nothing flat.

The bolts were also polished down to remove the raised lettering on top. Started with 120 grit, then moved to 400, then to 800.
