Building a 6 Inch Scale Little Samson Traction Engine

The 6 Inch Scale Little Samson Traction Engine Building Project Starts Here

This website chronicles the construction of a half size (6″ scale) model of the Savage’s brothers Little Samson Traction Engine. It is reported that between 1904 and 1910 nine Little Samson 4NHP, 5 ton, steam tractors were built.

There are probably more than nine live steam models of this traction engine in operation today.

Video – Turning the Shafts

The crank shaft and 2nd shaft must turn freely. This is difficult to achieve if the hornplates are bent as in my case.

After straightening the hornplates in a home made plate bender the shafts can easily be turned by hand.

I have taken off the front wheels (which you can see in the previous progress photos below) so that I can get the front spring heat treated.

The two photos below show the Hornplates complete with Spectacle Plate and Front Plate (which is at the back!) offered up to the boiler but not fixed in position.

Clearly visible (that big black tube at the bottom) is the Axle Tube in which the back axle will run.

Also visible are two temporary spacer tubes. These will be removed later.

Tandem Build Progress Photo by Fergal in Ireland

Fergal Roche started building his Little Samson Traction Engine in 6″ scale (half full size) a good few months after me and he’s making spectacular progress.

The photo below shows the progress of his build as of 5 June 2016.

  • Thank you for starting this website. You take a lot of mystery out of building. A lot of books don,t have good pictures of engine or machining. Thank you thank you Where is the announcement list sign up?

  • Well done Alan. When you said a vid of me turning the shafts I thought you meant machining them.

  • Alan,

    Looks very impressive! I hadn’t realized the size of it. I now understand why you bought the Kinwa 430.

    Hope to be starting the shop build in the next month, finally.

  • Looks like you’re making good progress Alan.
    The rear axle tube alone looks like it must weigh over 50 lbs, then add on all the plates and connecting rods/tubes and I’m guessing the weight adds up pretty quickly. My back hurts just thinking about moving all those heavy steel parts around during the alignment and assembly phases 🙂

    Keep having fun,
    Mike

    BTW: I moved from Nong Khae to Bang Saen. (Chon Buri area)
