The more I think about water vapor, the less worried I am about rust and such. Just because open hearth stacks are so stinkin' tall. I can't see rust being an issue with nickel tracks and painted locos and rolling stock. Maybe I'll set one up when I get the track done and just let it spew for a month and see what happens.
Bill,
To your point about the height of open hearth stacks, it's possible to extend the length of the Lionel Industrial Smokestack (6-14142) almost indefinitely. This is done by cannibalizing a stack and using the middle piece. That will buy you about 8". The other thing you can do to gain height is to mount the stack inside the building (all stacks in the Weirton Steel OH emanated from the roof). That buys you about 6".
Here's a shot of two Lionel smokestacks (altered). On the left is a "shorty" created by removing the middle section and "donating" it to the one on the right. That 28.5" high stack will end up in my new OH. The shorty will end up in some other building - perhaps a powerhouse? That's still TBD.
Here are a few photos showing how the stacks were mounted in my old OH to increase their apparent height.
In this shot from the rear of the building, the wooden platform for the stacks is visible at the right.
This photo shows the mountings and wiring for both stacks.
Finally, this photo shows the stacks mounted inside the building. A piece of foamcore is lined up. You can see the markings where I am going to cut the holes. Later, the foamcore will be covered with Plastruct or Evergreen corrugated roofing.
Placing that cool misting unit at the very top of each stack would create a very realistic effect! And running the wiring, that's no big deal at all. I like this idea!
