A slightly larger farm engine model that I designed in 1976. Plans for building it were published in 1988 in Strictly IC, and again with improvements in that magazine in 2000. Many of these have been made both in the U.S. and abroad, and this model has been used as a project in technical schools for machine shop training. The bore is 3/4-inch, it has a 1-inch stroke and it can be made with or without hit-and-miss governing. There are no castings used except for the spoked flywheels. I know that lovers of brass have made several examples of this engine entirely of polished brass.
