Building a model Improved Ericsson Hot-Air Pumping Engine
This model is a 1/4 scale reproduction of an 8″ bore Improved Ericsson Hot-Air Pumping Engine dating back to the late 1800’s. It is nearly identical to the full size original 6″ Ericsson that I have in my collection. The model is in the form of a kit containing most of the major parts as unmachined castings straight out of the foundry, and a set of blueprints. As with my 1/2 scale Olds engine and 1/4 scale Mery engine, all machining, fabricating, finishing and painting, as well as assembly must be done to produce a usable engine. The engine itself went together quicker than I had anticipated, but the display became much more elaborate than I had expected, and took much more effort. All in all, a fun project!
