Hello Willie,

Thanks.

I call it a rotary slide valve.
I saw the inspiration for this valve on steam engines in steamships. And there are old pictures where such a valve is installed. I think it's a valve for quick maneuvers on not so big steamships.

What ever it is it must be catching... I have hardly been in my workshop for a couple of years. I did manage to make a list of easy things to do when I wandered in there earlier and even chucked up the material in a collet to turn up a couple of main bearings. I wonder how long it will be before I do those  :thinking:

Sounds like an impressive engine!  Do you have a picture of what it will look like?
Watching along!

There was a video of an American guy at YouTube, showing a test run at a show, but I can´t find it anymore.
Wow - thats fantastic!
I have just find the missed video again.

Today I didn't accomplish much. I made both cylinder heads, but I had to go across town and buy a slitting saw to cut the fins into the heads. I did have the correct slitting saw in my shop, but it had dulled from a lot of use, and it costs as much to have it resharpened as it does to buy a new one.

Yes, that's a bit crazy with the name of the condensate taps.
I only know this name “hissing cocks” from the Oktant model building catalog. (A model shop for model steam engines from Hamburg.)
But in old catalogs for valves and taps they are just called cylinder drain taps. It even has to be translated as hissing rooster 🐓. ( Zischhahn )   And we call the conical thing that rotates the chicken.  :facepalm:

The translation software can be funny sometimes. I remember years ago my mother was doing some geneology research on family in Germany, and the translation for one of the guys names came through as 'Cement Louse'.   :lolb: Sort of glad the papers didn't include a picture of him...   :Jester:
