I re-powder-coated the part that didn’t come out right last week. The problem turned out not to be lubricant leaking out between the steel and brass components. In fact, I had simply not cleaned out all of the grease from the inside of the weldment. When it heated up, it flowed out and ruined the finish. I ground off all of the powder coat and cleaned it inside and out before redoing it tonight. Afterward, I assembled all of the components. This will stay on the shelf until the prop comes back off.
