Half size Stuart 10 V.

[Michael S.]

Hello everyone,
Now the craft time begins again for me.
I could now continue with the projects I have started or I could start something new.
A few days ago I discovered a video on YouTube where someone was building a Stuart engine. But a little smaller than the 10 V. ("Make This Super Tiny Steam Engine From Scratch" is the name of the video.)
So I thought I'd give it a try too.
I suspect the engine was reduced in size by half. I don't have a blueprint for the 10 V. Only from the 10 H.
But I have a blue Stuart 10V that I didn't build myself. I use this as a template for the construction on a scale of 2:1.
The stand is built first in the video and I did it too......

I didn't want it soldered with soft solder like in the video. The holder for soldering is definitely very helpful. I expected that perhaps the brackets would also be soldered on and a screw was also soldered on.
But it all still has to be removed or something destroyed.
The two brass plates on the left and right of the stand were then soldered on with soft solder.
Afterwards everything was cleaned. Initially I'm happy with the result.
All parts are painted with paint.

Great project, and a great start! I like the jig used to hold all the leg pieces for soldering. Watching along...

´lovley ! i am following !

That's going to be a really cute little engine, Michael!

Looks good and I thought the 12mm bore engine I'm making at the moment was small!

I suppose it should be called a 20V as the Stuart numbers tend to increase as the size gets smaller

Great jig for the soldering, will be taking note of your methods, any insights into making steam engines that  approximate these sizes are of considerable interest to me. Like this half size model of a model I have been toying with the idea of a half or perhaps 1/3 size of Josef Reineck’s “Diesbar” oscillator. Brass engines always look good. Looking forward to seeing more. Regards, Paul Gough.

I think I have a drawing for the 10V somewhere Michael, I'll have a look when Im home and PM you some pictures if it will help. I also think Julius did a metric plan somewhere online (might have been on modelengineeringwebsite)

Here are the plans from Julius

Thanks for the good tips. A plan for the base of the 10V would be interesting. The rest, the crankshaft, the connecting rod and the slide control are identical to the 10 H.

The idea of ​​calling the motor 20V is interesting. The order of the numbers isn't really logical.
I took a picture of the stand setup. 20, 10, 7, 4 but 5 is the largest.

Since I still have a 10 V stand, the idea of ​​a tandem composite machine occurred to me. I think I've seen an engine like this somewhere before.

Is there any indication which RAL color from the RAL color catalog is very similar to the original stuart green?

Greetings Michael

I don't think there is just one colour, they have varied a bit over time.

Try RAL 6005 or 6011

Great fabrication process + jigs Michael

thanks Per,

and thank you Jason. Good to know that you can vary the green color a bit.

This may already be known, but I discovered that there must have been two versions of the stand. At one point the rib goes up to the cylinder flange and at another point it ends flat.

It is a very warm, rich, olive mid green. I have a RAL K7 colour fan in front of me but I am working from memory on the ST shade. I would say 6025 is about the right hue, but not quite dark enough while 6010 is dark and strong enough (lightness and chroma) but not quite yellowy enough a hue.  I would say 6011 is too pale (at one time at least, every machine on a Ford factory floor was painted 6011 Reseda Green). Can't think where Jason gets 6005 from, but what do I know.
