Very interesting ideas!
The next phase would have the stroke-adjusting disc position controlled by the boiler water level control, to automatically maintain water level...
And yes, I know there are other ways to do that, going back a century and more in time.
'Just for the mental exercise...

Russ,
There was some little success. The piston rod gland nuts were finished so it is possible to use the spanner to tighten it with the above shown spanner.
I will built the the eccentric rods from several parts.

Probably not, the mechanics should remain simple.... The next phase would have the stroke-adjusting disc position controlled by the boiler water level control, to automatically maintain water level...

The outer eccentric bodies were silver soldered.
Now i will mill and saw them as designed.

Good solution to save material.

Additive fabrication, saves material and machining difficulties.

On additive fabrication: Those who are not familiar with Kozo Hiraoka's excellent series in Live Steam back in the 70s and 80s would do well to examine one of his books or magazine artiles. Although somewhat smaller in scale than stuff many of us are used to, his fabrication techniques which rely extensively on fixturing and silver soldering parts together and then finish machining are well worth examining.

I couldn't agree more about Kozo's books.
I have them all, have studied his multitude of techniques and built two steam locomotives so far.
And silver brazing remains one of my favorite fabrication techniques.

Hi,
kozos books are one of the best i know.
The eccentric rods are ready. It is a composite construction. The head is soldered to the middle part and that is fixed with three M3-screws to the outer eccentric bodies.
I have built a soldering fixture so all four rods will have the equal length.

Hi,
then the forks were rounded so they will look nice and go free from other parts. I had built a milling fixture and panned the parts by hand.
Then the borings were reamed and the M5 x 0,5 mm threads cutted.

Dietrich,
Your work looks very good. I have to remind myself the scale that you're building at and how steady and patient you must be.
Love seeing your updates.
Cannot wait to see more
