My column-style steamengine

A special section just for steam engines and boilers, as without these you may as well fit a sail.

Will you just stop it already! You're making me feel inadequate ;) :lol:

I really like the brazing fixture for the trough. Very nice!

Hello,

every engine needs an throttle valve, so i have asked my library. I found two different solutions, a piston valve (STUART Undertype) and a slide valve (Navy K engine). The advantage of a piston valve is that the actuating forces are independent of the effective vapor pressure. That's why I chose it.

The valve body i have built from three gun metal parts, they were silver soldered.

There are four ventilation holes in the piston to prevent it from sucking at "full throttle" position.

Hello,

I wanted to know what it looked like in the work position, so I put it in this position.

I like it. For those who think that a simple ball valve would have done it - yes, but a technical solution should also look nice

Next step will be to built the quadrant and the operating lever.
