WORKING VERTICAL COKE BOTTLE STYLE MILL ENGINE
This is a 1/8 scale model of an original engine manufactured by the Orr & Sembower Company of Reading, Pa. The original engine was a six horsepower class F engine according to the Orr & Sembower literature. We scaled this model from an actual engine that came out of a nitroglycerin plant. It was used to mix the acids and glycerin for making nitro. Even after gas engines and electric motors became commonplace, steam engines were considered much more dependable. When mixing, they couldn’t stop; for if they did, it was time to run for your life. With the boiler in the distance and high torque at low RPMs, the steam engine was much safer. This makes a beautiful model that you will be proud to own. But please don’t make your own nitro plant. We like having you as a customer. Kit complete with 18 bronze and iron castings, all required hardware, gasket material, bar stock and complete working drawings. The base platform is cast aluminum. Machining and assembly required.

Quite a tricky engine to build. Castings very accurate.

Ordered on Tuesday and received Friday in California. That is fast service. The castings are very clean. Going to be a fun build.
Good running engine. It was entirely machined in 3 weekends and ran within a month. The iron castings are a bit harder than I’m used to so be sure to use high quality taps.
