All Engines

3 pages of Plans for model steam engines and photographs of a few of my working models and projects. All of the steam engines where built using normal home workshop tools and a minilathe. Beginners should start with the bar stock engines (Elmers engines No. 19 has been recommended as a good starting engine) See Page 1, Page 2 and Page 3

Plans for Basic jet turbine engines along with some pictures of the first engine that I made and pictures of the latest project - jet engine plans will be added to the site for download when the engines are finished
