Oscillating Steam Engine

Plans for the Oscillating Steam Engine, this is a large model at 240mm long x 80mm wide and 90mm high. At the same time it is easily built using a small lathe and milling machine. I designed and made this when I bought the Warco WM240B lathe. This was to be a simple larger scale engine than what I had made previously.

  • 15mm bore
  • 50mm stroke
  • ball races for main bearings
  • ball race on the conrod big end
  • feature thumb nut used to apply pressure to oscillating cylinder
  • 100mm (4″) diameter cast iron flywheel

This engine runs like a dream even at low pressures. The main chassis frame is made from 3 parts all 1/4″ thick mild steel plate. Commonly available from model engineering suppliers.

The plans come as a pdf download – the link is provided on the payment confirmation page. These plans have a title page and 14 pages of detailed technical drawings enhanced with the designers notes and images of the actual engine made by Nigel Taylor.

This is a great starter engine design for those new to model engineering or a design that can be built and improved.
