Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

    Two Stuart S50 engines, the green one I have had for a long time but it needed a lot of work, the black one I acquired only very recently, and it prompted me to finally get around to attending to the first one. Required a third donor S50, as the original driveshaft on the green one was bent, along with plenty of other issues and parts swaps. Fortunately the black one required nothing more than a good cleaning, it was covered with a layer of dried steam oil residue, which had protected it well (it had clearly seen a lot of run time). Both are now absolutely tight and smooth runners, the black runs on barely a puff of air. I believe that both are older models, having the bronze cylinders and valve chests.

Nice looking engines!  Next in the build queue for me is a Stuart S50 and I'm looking forward to the build.

   Thanks to all for the comments.

   Gil, good to know the likely source of the governor itself. The engine came from England, but if your friend was offering them for that long, then no doubt some would have ended up there (maybe even more than anywhere else). It is certainly a fine piece of craftsmanship. I have only seen a few S50 models with governors, apparently Stuart does not make them specifically for the S50 today, but maybe they did in years past.

A couple of nice engines
 From what i can see the governor is only for looks and non functional

Cheers

Ok so the governor is functional .
I am at a loss as to how .
I am not doubting you but obviously i need to do more homework as to how they work

Cheers

Hi Greg, Stuart never provided a governor for the S-50. It is 100% John Coleman's work. John was a very good model engineer

  Thanks Gil for confirming the ID on my S50 governor. Nick, I would be interested to see photos of yours also, thanks.

Very nice looking engines, well done Greg!

@Dennis
Took a second round for me as well
