Frank is looking for advice from anyone who has experience building scenery and structures:

“On a large HO layout I want to use an old grist mill with a dam and running water over a water wheel. #1 I’m concerned the water may have a corrosive problem for the train? Will it? #2 Is there a good substitute for water without the problem of corrison. Forgot to mention I would like to add a waterfall (apprx 12- 15″) close to the mill site. Thanks.”
