Hello one and all

My uncle had a National diesel engine to generate electricity on his farm. This thing is huge. It ran on used car oil and had 1 cylinder of 12 inches. It was horizontal and had a flywheel of almost 2m in diameter. I don't have more information than that. Where can one look for plans for such an engine? I like the idea of building a replica of an engine that existed and this one has sentimental value to me. I realize of course that there aren't plans simply because a model builder wants plans but I thought maybe someone could point me in the direction of something similar for which there are plans. I hope I can go to the farm one of these days to get some pics. It does not run anymore and I doubt it ever will.

Thank you
 
One engine that you may be able to adapt for your project, is the Centaur gas engine there are plans and castings available for this engine in the UK see link.

Thank you, I see the plans are free to download off their site. Great stuff!!!
I don't think the plans are a free down load, however there is a PDF available of the the original article of the engine build which will give you the size of the model and description Link

Very dusty and the space is cramped. Could not get good pics showing the whole engine. The toilet roll is for scale :) just kidding....I did not put it there.

R: "It does not run anymore and I doubt it ever will". That may be true of my body, but there are plenty of restoration groups around who buy engines for scrap value - and then restore them for their museums. But you must be sure (from their websites) that they are museums, not traders. And who the real owner is....
The handicap is often the cost of getting lifts and transport from the site to museum. That can be more than the scrap value of the bits, so no-one wants to know then...
The loo roll does add a perspective of size, so is a valuable addition to the photo!
Does the generator still exist? - Full of copper windings it will have a high scrap value... - but high cost for re-winding too. - If the insulation has broken down with age...
