A kit where the cylinder and the engine base had already been machined served as the basis for this steam engine project. I machined the missing parts in accordance with the original drawings, changing all threads and bolts to metric. Since the originial flywheel was missing, I decided to obtain a finished one from Wolfgang Bengs, who makes these flywheels on a CNC machine and by now has expanded his shop, also offering high quality accessory parts for steam  engines. I nickel plated some of the shiny surfaces of this model.
