steam-engine-model-55This is a single action Open Column Twin Cylinder steam engine and actually the first one I ever attempted to build. The design it’s not mine. This is something that I came across on the internet when I was searching for blueprints and it looked cool to me but also neither too simple nor too complicated to make. The drawings are complete, the engine is well designed and it’s working perfectly. Although the engineer didn’t take into consideration the machinist’s way of seeing, building and measuring things and a lot of the dimensions must be recalculated. What made things worse for me was that I had to convert everything from inches to millimeters.

If you interested in building this steam engine you can find a link to a PDF file that includes the drawings and a 3D model of the engine on the Download section of my Blog.

I used aluminum for the engine block and the pistons, so you can tell that this is a light duty engine. It never was at my intention to run this engine on steam. I’m using a low pressure aquarium air pump instead. Although you can build a real heavy duty engine from this drawing’s by using different materials. Most parts of the engine have been made on my mini lathe before I purchase my mini mill, but I could be easily complete the entire project on my lathe by using the milling attachment.

    1. Hi and thank you for your kind words! I’m not an expert on engines, this my first small engine that I ever build but I’ll be glad to help if I can.

  1. Hello Baseline46

    I really like your website. Since I also own a D180 x 300 lathe from WEISS, you have fantastic video examples what is possible with this machine. So now I am also trying to make the twin cilinder engine.
    I first make a full 3D model in rounded millimeter measurements, so it is not exactly the same as yours. If you are interested, you can have a 3D PDF file.

    Regards, Willie

    1. Hi Willie and thank you for your kind words! It would be nice to add your 3D model in the post. I’ll send you an email… Regards, Dimitris

  2. Hello Baseline46,

    I just want to thank you for your Blog and the nice videos.
    I plan to buy a mini Lathe, and your Blog and Videos underscore my decision to buy a Optimum Tu2004V, which is equal to your D180x300 i think.
    I did not think that so much is possible with this little Lathe.
    I think this Machine is worth her price.


  3. Hello
    Building a Steam Engine;

    I would very much like to build the engine, are plans available please?
    I d’ont find 2D plan on the download page.


  4. Awesome work, well done! I own a similar lathe, 210×300, and a small milling machine. Did you make the drawings in mm? The pdf file shows only inches, and having the converted drawing to mm would make things easier for everuone that would like to make the engine. The challenge is building the engine, not spending days and days converting from inches to mm


  5. Dear Dimitri,
    I have managed to find at last the download of the drawings. John-tom etc. I even found a larger metric version, but I prefer the smaller model even though my lathe swings 13 inches and my milling machines one Horizontal and one vertical are not too small. Thanks anyway I think I will make the cylinder block of cast Iron or steel, the rest of the pieces Aluminium and Brass (Bronz).
