The weather has finally improved so I spent the afternoon persuading the last of the screws that held the base on and then started attacking the rust. Only two screws needed to have their heads popped off with the hammer and cold chisel. The rest after a soak of WD-40 and a few taps with a hammer unscrewed with almost no effort.
There is a piece of sheet metal that rests in top of the base I will have to replace.
I’m using an angle grinder with a grinding disc first to clean off the scale and buildup, then I swap in a stripping wheel that brings it down to the bare metal and scours any remaining rust. Then it is sprayed with a rust converter. Once all the rust is done I’ll spray down a red oxide rust paint and then a primer. The final coats of paint are applied once I’m done working on the underside.
I mentioned before I need to sandblast some components because I can’t reach into the tight spaces with the grinder. I found my bottle of sandblasting compound but now I need a compressor with a large tank capacity. Anyone willing to lend theirs out?
I also pulled a few of the components off the door so I could lay it flat without things getting more messed up. This is the little fan at the bottom of the doors. There’s a duct behind the mechanism that blows air over the doors for some reason. Condensation protection?
I never powered it up, so the winding must of burned out years ago. The fan itself spins freely. It’s a basic induction motor so I can steal another one out of just about any bathroom fan.
