Very nice - its so nice to see an excellent display

In my project Klosterstollen I build models and vehicles on this topic.
Since there is nothing that you can not do even better, I have dealt with the Schalker battery locomotive again.
I had the impression that it was just too broad.


As it should be, I then measured the model of my Schalker.


In the Feldbahn Museum Frankfurt an original could then be measured and lo and behold my model of the Schalker was 4.4 mm too wide.


In one bundle I was able to buy, among other things, 2 identical models of the Schalker battery locomotive. I disassembled them and sawed them out on a circular saw 4.4 mm from the middle with a finely toothed 100mm saw blade. I shortened the buffer planks at the end.


Put together to sample and I think it looks much better.

The difference is subtle but noticeable ... and an improvement. -- Russ

[Bill Gill]

It does look better.

[Ray Dunakin]

I agree, a subtle but noticeable improvement!

Hi Helmut.
Great to see you posting again , I hope your recent injuries are healing well.
All the best Kim.

My latest project for my monastery tunnel model.


The heavy mine train coupling on a submarine.



The core of the coupling are the suspensions milled from 2 mm brass sheet for a standard mine wagon.



For the soldering itself, I also milled spacers from 1.5 mm thick aluminum sheet.



Items prepared for assembly. The sawn MDF blocks are soldering aids.



The original is welded together from sheet metal plates, which I converted into the model and milled out the parts from 0.5 mm nickel silver sheet.



Here is the 0.3 mm cotter pin, ground down from a brass wire and bent by hand, for fastening the chain.



Individual parts for the clutch. The 15 mm long chain gets a cotter pin at each end. The coupling pin has been pierced twice with a 0.3 mm drill bit before bending. A 0.5 mm stainless steel wire was soldered into a hole. The wire was ground flush at the top and shortened to 0.75 mm at the bottom. The pin prevents the coupling bolt from falling out in the latch. A piece of M 2 threaded rod was soldered into the central center piece of the coupling, over which the compressive and tensile forces are transmitted to the spring.



The first individual parts are soldered together with the soldering aids.



The first 4 couplings are ready and can be checked for function.



A clutch with a pulled coupling pin.



The coupling with inserted coupling irons.



Coupling to the locomotive.

Ho-hum, another superb component. -- Russ

Wow! Excellent work, very impressive!

[Bernhard]

Nice little detail work.

Hi Helmut.
yes, a beautiful bit of mini-functionalism.
