Here is one I found by a google search of wheel wrench.

Now I have to make a scale version for my mini tool collection.

Yep.....thats it Dan 'there was one or two on every deck of the engine room in a pipe welded to the railing'. including the E/R bottom Flat where the valves for Sea Chests to manifold pipes connected again with isolation valves to Eductor and Ballast mains

The 'wheel wrench'   :killcomputer:, absolutely invaluable  :ThumbsUp:

The Menck steam shovel is now equipped with a non functional ashpan, which can easily be removed to give access to the compressed air connection.

The crowd engine now has levers connecting the reversing-valve to the operator’s place. As the crowd engine does not really work with compressed air, I decided to make scale size steam pipes which can’t take air pressure. The flanges are held by 1 mm brass screws. There was no flexible pipe connection between the house and the boom. To move the boom, six flanges had to be unscrewed.
Walls and the roof of the house are removed, awaiting painting. I will make a display cabinet for the model to protect it from dust.
Kind regards, Horst

Hello Horst,

this will be a very good model of an excavator.
Maybe I can admire it live at some exhibition.

The Menck IV steam shovel model is now painted. That's the end of building phase one.
Phase two now starts with attempts to improve the crowd and slew engines. Some design work will be necessary before I can start cutting metal.
Kind regards, Horst

Wow - place it in a different background scenario and you might fool people to believe it is a full size (for that, it might also need some wear and tear + fading colors)  :praise2:   :praise2:

Horst:

Did you mean that for you to move the boom you have to unscrew the flanges?  If that's the case then maybe you could slot the flanges and leave the bolts loose enough to allow the flanges to rotate?  That way you could raise and lower the boom without having to tear it apart.

Hello Don,
I‘d like to stick to the operation of the original engine. They had to loosen the screws on the flanges, so they avoided moving the boom.

Can you explain more about moving the boom? I must have missed that earlier in the thread and can't find it. Which parts dont move easily?  :headscratch:

Hello Chris,
It‘s the steam pipes to and from the crowd engine, see the second picture in my April 17th post. There is no flexible steam connection between the house and the boom. Six flanges had to be loosened to move the boom. Actually I haven’t found out how they lowered the boom, as there is no brake for the winch.

Horst
Kind regards, Horst

Ah, now I understand.  Most of the shovels like that only lowered the boom down for transport, in operations the boom stayed at that fixed angle and the dipper stick did all the up/down/in/out moving. For loading the machine on a rail car for transportation, the stick would be removed, all pipes disconnected, and the boom lowered down using the bucket cable reconnected to the end of the boom. On the Marion I modelled there were extra pulleys used just for that process. I'll check the catalogs for pictures of that...
