Thanks Dave. That car is On3. Most of my work is On3, although I also work in HO some. I have misc pics on my blog (there's a link in my sig). I'm currently building 3 passenger cars. I'm getting close to the roof phase. The roof, minus the ends and sheathing, took me a single evening. The beauty of working with styrene. The sheathing was 0.010" thick styrene which readily bends and holds the shape once glued. I suppose that the best way to cut curves in brass would be to create some sort of turntable to use on a scroll saw, a nibbler, or a jeweler's saw.
