We've got a little of this and a little of that going on today. Let's talk about cats, specifically one that is on my s*** list. Maggie got up on the layout, which isn't a problem unless she bumps into things and does this... 
Fortunately, it did not fall to the floor. I found it laying on a box under an access hole in the Staging Area.
While I was working on the Open Hearth, I decided to remove the tubing for the smoke generator that supplied the stacks. Here's what the tubing looked like after the unit failed and started to burn. 
It was a lucky thing that I was standing there when the unit failed and started shoot flame up into the "T".
Yeah, not good. But I haven't given up on the idea of smoke coming out of the stacks. Originally, I bought this Seuthe #500 unit for another project, but it's just too big for that. However, I think it might fit in the top of a stack with wires running down, through, and out the bottom to my 12VDC power supply. We will have to build a cradle 2" wide to fit in the top of the stack. The unit uses the bottle as a supply, so the cradle will be a bit tricky. I'm still working out the details. Right now, it's mostly a glint in my eye.
Replaced the Lean-To roof sections that had been misplaced (or cannibalized) after the roof rebuilt. They got weathered today as well. Here's the Charging Side and Lean-To portions of the Open Hearth. The stacks got more gray and a hint of red residue. DullCote is still to come, which will tone down the brightness of the red.
I also got to the Pouring Side and did both the roof and side walls.
And here's a closer look at the front of the Pouring extension. I'm hoping some additional pipe supports arrive on Monday, which will allow me to finish running the pipe across its front.
More when I know it.
