Hey Val, I guess you mean the "cutting up" of brass locos and such. Once you cut that first gaping hole in a $500 brass loco tender, it's all down hill. I'm working on another one of Gary's locos, this one is a NYC K-5 Pacific. It is getting a speaker for future sound installation. This time the speaker will face down. Usually I cut a hole in the coal bunker and mount it there. On this one I just bored about 100 little holes through the floor. I should post photos on the Yahoo brass collector's site. That scene would just peel the enamel off a collector's teeth!
