In Great Britain, the term steam tractor is more usually applied to the smallest models of traction engine - typically those weighing seven tons or less - used for hauling small loads on public roads. In North America, the term steam tractor usually refers to a type of agricultural tractor powered by a steam engine, used extensively in the late 19th and early 20th centuries.

Maximizing the Efficiency of Steam Locomotives: Interesting data on how to make your steam engine more efficient. A steam tractor is a vehicle powered by a steam engine which is used for pulling. Steam Happens: Some good photos of Stevenson Linkages for steam launch engines. – Crankshaft length needs to be adjusted at either endĮncyclopedia Titanica: Article on Titanic’s Steam Engines: Great diagram of how a Stevenson Linkage works on a slide valve engine. – Slide valve has an interference with the eccentric rod Rotate the engine until the piston is 1/16 and 1/8 inch before bottom dead center and grind the exhaust cam so the valve just starts to open. – Cylinder mount has an extra bolt hole adjacent to standard. This is your starting place so make a new timing mark. – Detail on connecting rod to slider fasteners – Steam exhaust fitting on steam chest cover and gland – Steam inlet fitting to steam chest and gland This will also simplify and clean up the steam box, as well as eliminating a difficult setup that would have drilled the ports at an angle to position them closer to the ends of the cylinder.Ĭlick here for a page describing how I accomplished the “porting” in Rhino3D. In this improved design, a 1/8″ diameter end mill cuts a short arc into the cylinder wall to provide clearance for steam entry around the piston.

I took things a step further since I’ll be using a CNC and did a full “porting” job: Someone suggested I could vertically mill a groove into the wall of the cylinder to eliminate the bizarre piston shape and I thought it a good idea. This was to provide clearance for the steam passages. The astute observer will note, as several have, that the piston in the above renderings is very strangely shaped. Redesign of the Steam Passages and Hot Rod “Porting” Job It took me about 7 hours of work with Rhino to bring the model to this stage. The right hand side view with a better look at the steam chest… As of July 13, 2008, this was the current status of that model: I’ve started by creating a 3D solid model of the engine using Rhino 3D.

The 3D model has been pretty far along for some time but I am just now getting an update posted:

You can download the Rhino3D model over on our CAD Download Section. The proportions of this model cannot be faulted, and I’ve had a hard time trying to make sure my version is at all true to those aesthetics. The list below contains all the parts to build ONE model steam engine (Special fuel tablets and silver solder must be. This project was inspired by the Engineman’s (John Bentley’s) gorgeous naval brass version of the original Stuart Turner steam engine. It’s not finished, but wouldn’t take much to finish it up and start machining.

One last item, I would build a code boiler because you can sell it easier and get most, if not all of your money back if not make a little on it when you sell it.Here’s one from my archives. Ternings no longer has the 1/4 scale castings I know who bought them from him but castings are not for sale at this time. There are many 1/4 scale sawmills around that were built to complement the steam engine. You can operate anything with a 1/4 scale as long as it is also built to scale. I am considering a 3/4 ton but not because of the steam engine, but the fact that I can get a new F250 with the options I want for less than or equal to the same amount of money as a fully loaded F150, and also because I would like to add a truck camper. I have a 1/2 scale of a 65hp Case and I pull it with a 1/2 ton truck on a flatbed trailer. It will also fit on a small trailer or the bed of a pickup and you can tow it without having to buy an F350. BTW, a 1/4 scale one might not be able to run a sawmill, but it can drive around and pull a wagon.
