A bottle engine made from an old gas tap.

No! Starting on November 3, 2025.

Ah, I was going by the posts just from the last few days. Its coming along great!

It looks great, I love the round valve chest, I haven't seen a model or actual engine with one before.....

Great stuff Michael!

Great project . 
Another way to build a engine.
Thanks for sharing !

The steam channels have been milled. A ring was manufactured to serve as the valve chest.

Using a complex CAD simulation ( Cardboard Aided Design ), I was able to determine that there was space for a slide valve.

When drilling the two steam intake channels, I again used my paper method. And it worked well again.

Finally, everything was assembled, and a few parts for the steam intake line and exhaust were fabricated.

That's has really come on a long way and looks fantastic; I love the use of the modern paper technology for your calculations, it puts AI to shame!

It's looking beautiful, Michael! 
And you do have amazing CAD skills!

clever use of the tap !
the resulting engine is very elegant !

and with the other part of the tap ?

[Michael S.]

Oops... why does it smell like gas?

Oh no, everything's fine.

The rest of the gas tap was made of cast iron and has been in the Junkyard.

So cool!

Very nice 

Real CAD is a most important skill

Today I made the piston and piston rod. Then I made the crosshead. The piston and piston rod are made of stainless steel, and the crosshead is made of cast iron.

Its really coming along and looking really great! I can't wait to see this one running

For those with money and the space I saw this bottle engine for sale - no I'm not buying it, divorces are expensive
