Very impressive work. The tools hanging in the background give a great sense of scale! :ThumbsUp:

Great thread, amazing model with the real shovel behind, fascinating!
the attention to the mechanics is clearly first class.
thanks to share this build !

I don't know how I missed this thread but now that I've seen it it is truly and amazing piece of craftsmanship! Outstanding detail. How many trips did you make back and forth to get pictures and dimensions?

I had about four trips to one of the „surviving“ shovel. I couldn‘t have made the mechanics without a reprint of a 1930s engineering handbook containing sketches of components hidden within the original machine.

The last few weeks I have been tinkering with the house on the superstructure. Frames and walls are now almost finished.
Now that the beautiful mechanics are largely hidden, I have made part of the roof and walls easily removable with clamping mechanism.
Aligning frames and walls was more complex than expected. There are no sufficiently large straight surfaces to which you can apply an angle. In the original, the housing is screwed together, as it was removed during the transport of the machine. That's why I also worked with screws in the model. The M1 brass screws are reasonably scaled, but handling requires a lot of patience and concentration. Two socket wrenches size 1.6 mm were indispensable. The screwed-in sheets made the house surprisingly stable.
Primer and varnish follow as soon as it gets a little warmer in the workshop. This will end phase 1 of the construction project. In phase 2, refinements will be added.
Kind regards, Horst

That‘s the camera‘s idea of automatic colour temperature adjustment, just confused by daylight coming in from the left side. I am not very good in correcting colour in Lightroom, so I left it.

After walls and roof of the house are finished, waiting for higher temperature to get painted, I started making the levers and steam pipes for the (not functional) crowd engine. To move the boom on the original engine, six flanges of the steam pipes had to be loosened. Therefore a steam valve was installed near the operator’s seat. My model steam valve lets the air  through, but it can’t block the air flow. I would need shop elve’s help to operate the model hand wheel because there is not enough space for my fingers. I tried to make curved spokes in the hand wheel like on the original. It’s not perfect, but shows the shape.
Kind regards, Horst

Horst.....not sure if you are aware, but in real life, globe valves in industry [especially marine] were tightened & unloosened  :hammerbash: by a manual lever with a twist knuckle in the head....this grips the spokes in the valve rotary wheel handle

This was especially important where hand operation was not physically practicable due the location of the valves

Again in many cases these handles were hung against the railings surrounding these series of valve chests

It's a generational thing, today all of these valves would have a pneumatic or hydraulic actuator with proximity switching and all linked to a PLC system..............in earlier years :old:, humans were needed to open & close these valve functions

Horst, nice looking valve and handwheel.

Derek, on this side of the pond we call that tool a wheel wrench. Most of them were shop made from a 3/4" round bar with two pieces welded at a 90-degree angle. There was one or two on every deck of the engine room in a pipe welded to the railing. I made one up in my shop to bend red hot iron.

I should make a 1:12 wheel wrench for the shop elves  ;D
