I had this posted on another forum a while back when i did these buildings in N scale when i was doing N Scale Steel Mills
This one is of the Walthers Cornerstone N Scale Blast Furnace, thought you guys might like to see how i built them. So these threads will contain the building and weathering process from start to finish of each of the 3 Steel Mill buildings i did. Hope you enjoy them if you have not already seen them

Step 1
Here I have assembled the Furnace halfs, the Bust Pipe, the Mantle ring to the Bust Pipe, the Bell Hopper, and the Sheaves to the Sheave Rod.
Step 2
Here I have assembled the Bell Beams and the Trolley Support. I then put the Bell Beam in place on the Trolley Supports and also glued the Sheaves and Sheave Rod in place on the top of the Trolley Supports.
Step 3
Next I glued the Trolley Braces in (front and rear tops) and glued the Mantle Ring and Bust Pipe to the Furnace.
Step 4
I glued the Bell Platform to the Furnace.
Step 5
I put the pipes together but only glued in a couple spots (it says to leave the others unglued for now for later assemble. this was just a pre-assemble on how it goes together) and placed the Trolley Supports in postion, again, not glued in place yet.
Step 6
I glued the supports for the Mantle Ring to the Ring and then to the wall of the Furnace.
Step 7
Was to glue the supports for the Bell Platform to the Platform and the Furnace
Step 8
Glued the Bell Hopper to the top of the Furnace.
Step 9
I glued the Trolley Supports to the Bell Platform. I noticed that the Beam Bells were in the wrong spot because the Trolley Supports would not fit because of the location of the Bell Hopper. I moved the Beam Bells to the right loccation which is right next to the Sheaves and Sheave rod.
Step 10
I then put the top of the furnace together. I glued the Bleeder Platform to the tops of the Offtakes. Then the Bleeder Valves and Bleeder Handles were added on top of the Bleeder Platform. Next, the handrails were added around the Platform and was finished off by glueing the Platform Bracing to the top.
Step 11
Next was to glue the Offtakes to the Lower Offtakes on the Furnace. Now the Furnace is almost complete. All that needs to be done is adding the handrails around the Bell Platform and painting. The handrails will be added after they have been painted yellow. The furnace also gets a nice coat of rust brown primer. That's the next step.
Step 12
I sprayed the Furnace with rust brown primer and the handrails have been sprayed yellow. The paint is still wet and the flash on the camera was used for the furnace so that is why they look so shinny.
Step 13
Here is the finished Furnace with yellow handrails. You can see that the color is more of a rust brown and that the railings are a real eye catcher, just what I was going for.
Step 14
I started to assemble the Hoist House and Main Furnace Building. I sprayed the brick encasements on the columns grey, they were originally a yellow brick and looked really bad.
Step 15
Added 2 of the Main Furnace Walls. I painted them an Aluminum color and I will weather the heck out of em so that they look more like if has been there for a while like the rest of the furnace.
That is Myth Busters on the TV in the backround, love that show lol
Step 16
Was to start the Cast House. This is one of the 3 support walls. Again, the brick encasement's have been sprayed grey instead of that nasty yellow!
Step 17
Here is the finished Cast House. Next, the Upper Cast House Floor will be installed.
Step 18
Was to paint the Cast House 2nd level floor to the rust brown primer color. This was also the ugly yellow color that the brick encasement's were molded in. This pic is of it still wet, it will dry the same color as the Furnace. You can see were the molten hot steel would run along the paths to waiting hot metal cars on the tracks below.
Step 19
Here are some pics of the Cast House Top Level Floor in it's final postion over the Cast House and Main Furnace Room. I glued the floor down and added another wall to the Main Furnace Room wall. I also added Slag Runner Roof Supports.
In the next 2 or 3 steps, you will see the main building take shape with roofs and the rest of the walls being added on
