Updated 3/26/2025:
It was too cold to open the basement window ventilation system (we had snow this morning!!! 
) and apply DullCote. Instead I worked on the pipe bridge that will sit between the Open Hearth and the Strip Steel mills.
Here's the beginnings of the assembly.
Since the area underneath the pipe bridge is a roadway, it makes sense that the inner sides of the columns would be (sloppily) painted yellow so the 1:48 truck drivers can see them.
I'm using this piece of wood as a spacer to mount the pipe vessel saddles.
Finally, here's a test fit of the coke oven gas pipe on the vessel saddles.
More when I know it.
