OZ and David,
Thanks for looking in and kind words.

The belt material arrived and a belt was made.
A video of the engine running and testing the governor.

With the governor working, the post and valve was removed for some finishing work.
The post set up on the mill.

A few holes were drilled and bored.

The corners were rounded over.

The finished post.

The corners on the valve body were also rounded.

I needed a connector for the exhaust. Started by turning and drilling a piece of rectangular brass.

After cutting it off it was mounted in the collet chuck to face and put a radius on the outside of the flange.

I did not have any round brass for the outer part and had to turn down a piece of hex bar. The end was threaded 3/8-32 ME to take a commercial union nut. The inside was tapered with a centre drill for a union coupling.

The two pieces done.

The pieces were silver soldered together while soldering some other bits
The governor parts and exhaust connector after a bit of polishing.

The coupling mounted on the engine.

The governor remounted on the engine.

And finally a couple of videos of the engine running. (sound is unfortunately a bit bad)

I will be building a generator to go with the engine that I will post in a different thread. Once that is done they will be painted and mounted on a base.

Thanks to all for following along.

Cheers
Abraham

Hi all.

Am finally at the last stretch of this build.

For the base 4 pieces of wood had their ends milled at 45 degrees. The only way I had to hold them was an angle plate and two large gudgeon pins,

They were milled to with.

And glued together.

Forgot to drill a hole in the one end piece and had to set it up on the lathe do drill it nice and square.

A mounting adaptor was turned from brass to fit in the hole in the base. A DC power connector will be fitted in the adaptor to supply excitation to the generator.

After the base was stained and varnished a DC motor speed controller and the connector were fitted inside.

Then the fun started with painting all the parts. In the end it took 4 tries and a change from brush enamel to aerosol spray. On the smaller parts the painting was done with an airbrush.

The cylinder was lagged using stained and varnished ice-cream sticks and bands made from brass shim stock.

The steam chest cover was engraved on the CNC router. (nearly 150000 lines of code and two and a half hours running)

And the background was painted.

Finally the completed engine set.

My dear wife assisted me in making a short video, it was a bit windy so the sound is not so good in a few places.

Thank you to for following along and encouragement given.

Cheers
Abraham
