27-Oct-2002. Alternative layout for the water tank. The plans call for a square, windowed box to simulate a modern cab, which doesn't look right to me at all. Here I've fashioned a rounded tank that hugs the boiler. I think it would look really sharp with the rounded corners, and being against the boiler will pre-warm the water. The drawback to this design is it's added complexity. All those rounded curves will require bending, soldering or welding. And the tank would look best if it were riveted!
