Steamboat Engine Specifications

Some have wondered why there is a set of plans for a Mississippi river steamboat engine on the same web site as radial engines.
The reason is that In 1984, my father vacationed on the Delta Queen steamboat and became fascinated by the California cutoff valve gear. All of the detail pictures he took, did not come out.
Working from memory, and from the text of an International Correspondence School textbook, he was able to build a model of a similar engine.
It is an unusual engine and the only model of its type available to the model engine hobby.
The original engines are horizontal cross compound with a HP Cylinder of 26"diameter, the LP Cylinder is 52" diameter, the stroke is 10 feet. The engines are rated at 2000 horsepower at 13 RPM.
